THE FORAMINIFERA OF THE TROPICAL PACIFIC COLLECTIONS OF THE “ALBATROSS,” 1899-1900
Part 1.—ASTRORHIZIDAE to TROCHAMMINIDAE

Director, Cushman Laboratory for Foraminiferal Research
UNITED STATES GOVERNMENT PRINTING OFFICE WASHINGTON : 1932
ADVERTISEMENT
The scientific publications of the National Museum include two series, known, respectively, as Proceedings and Bulletin.
The Proceedings series, begun in 1878, is intended primarily as a medium for the publication of original papers, based on the collec- tions of the National Museum, that set forth newly acquired facts in biology, anthropology, and geology, with descriptions of new forms and revisions of limited groups. Copies of each paper, in pamphlet form, are distributed as published to libraries and scientific organizations and to specialists and others interested in the different subjects.
The dates at which these separate papers are published are re- corded in the table of contents of each of the volumes.
The Bulletin series, the first of which was issued in 1875, con- sists of separate publications comprising monographs of large zoo-
/logieal groups and “other, general systematic treatises (occasionally
on
‘fin several volumes), faunal works, reports of expeditions, cata-
. logues of type specimens and special collections, and other material of
similar nature. The majority of the volumes are octavo in size, . f
but’a’ quarto sjze-ha& heen adopted in a few instances in which large plates*were-regarded as indispensable. In the Bulletin series appear volumes under the heading Contributions from the United States National Herbarium, in octavo form, published by the National Museum since 1902, which contain papers relating to the botanical collections of the Museum.
The present volume forms No. 161 of the Bulletin series.

THE FORAMINIFERA OF THE TROPICAL PACIFIC COLLECTIONS OF THE “ALBATROSS,” 1899-1900
Part 1.—ASTRORHIZIDAE TO TROCHAMMINIDAE
By JosrrH AUGUSTINE CUSHMAN
Director, Cushman Laboratory for Foraminiferal Research Sharon, Massachusetts
INTRODUCTION
THIS PAPER is the first part of a work the intent of which is to describe and illustrate the foraminifera of the tropical Pacific collected by the United States Bureau of Fisheries steamer Albatross, together with certain other related material from shallow water of the same region. Parts 2 and 3 will take up in systematic order the rest of the families after the Trochamminidae.
Numerous papers deal with the shallow-water foraminifera of the Indo-Pacific, but from deep water few records are available for the general area except those from the Challenger expedition of 50 years ago.
Two previous bulletins of the United States National Museum, one on the foraminifera of the North Pacific Ocean (Bulletin 71, 1910-1917) and the other on the foraminifera of the Atlantic Ocean (Bulletin 104, 1918-1931), are general accounts, especially of the foraminifera dredged by the Albatross. These bulletins also include many of the species recorded from the same areas in other pub- lications.
The collections of the Albatross made during the voyage from August 26, 1899, to February 21, 1900, form the basis of the present series. These were made largely in deep water, although many of them were in the immediate neighborhood of oceanic islands, par- ticularly the Paumotu group. Shallow-water collections made from this same area have also come into my hands for study and greatly supplement the fauna obtained in the deeper-water dredgings. A few of the stations are in north latitude, especially those near the Marshall and Ladrone Islands. The fauna treated, however, is all more or less of a unit, and the fact that some forms come from north of the Equator and most of them from south does not interfere with the general unity of the paper.

2 BULLETIN 161, UNITED STATES NATIONAL MUSEUM
Most of the papers published on the foraminifera of the Indo- Pacific region are cited in the synonymy under the various species, and in some of them species were figured and described that were not obtained in our collections. To have added all the other records from the general Indo-Pacific region would not only have greatly enlarged this work, but would have involved the addition of many species the types of which were not available for study. It has seemed best, therefore, to limit the scope of the work to the actual collections of the Albatross and to the other available shallow-water deposits from the same groups of islands.
Though the fauna as a whole is a unified one, nevertheless the study of the present collections shows that there are in the shallow water about various groups of oceanic islands of the South Pacific locally developed species that are strictly limited. The species of deeper water, however, have a wide distribution.
Furthermore, there are numerous species that occur definitely asso- ciated in other areas. For instance, many are widely distributed among the islands of the South Pacific that are known also from the West Indian region. Others are known from the Mediterranean and the Red Sea regions. A few of them are very closely related to species originally described from the warm-water facies of the Miocene or Pliocene of southern Europe.
The accompanying map (fig. 1) shows the general path of the Albatross during this voyage, and for further details the reader is referred to the tables accompanying a number of the species. These give the depth, temperature, and other data regarding the samples from which the material was taken.
The plates are all from original drawings made from the collec- tions by Miss Margaret S. Moore, and form perhaps the most useful part of the present work.
I wish to take this opportunity to express my great appreciation of the many kindnesses and the constant help that the United States National Museum and its staff have so constantly given me in the study of this and other material.

There are a few very fragmentary specimens of a tubular form composed of rather coarse sand grains, firmly cemented. These strongly resemble broken portions of the arms of this species, and are placed here provisionally. They are the only records for this family in the material examined. They are from Albatross Station H3779, latitude 24° 45’ N., longitude 130° 16’ W., in 2,627 fathoms.

Test composed of a series of pyriform chambers with a thin chiti- nous lining and the exterior composed of tests of other foraminifera firmly cemented; aperture extended into a narrow, cylindrical neck.
There are in the A/dbatross collections a number of specimens, some of which are figured here. These are composed of young tests of nearly uniform size neatly cemented. A few of the specimens simi- lar to that shown in Plate 1, Figure 1, are evidently the initial cham- bers of this form. Although the stations are somewhat widely dis- tant from one another, the specimens are all very uniform in char- acter. They have been referred to this species, which in other locali- ties seems to lack the uniformity in the size of the tests that com- pose the wall.

Test free, early chambers planispiral in both microspheric and megalospheric forms, later ones biserial; wall arenaceous with a yel- lowish-brown cement; aperture in the planispiral portion at the base of the apertural face, in the biserial portion at the inner margin of the chamber. Carboniferous to Recent.
Out of all the Zewtularia group present in this collection from the Pacific only mlletti seems to belong to this genus. At this time com- ment may be made on the relationships of this genus to 7’extularia. Doctor Lacroix has recently published a paper on the relationships of these, seeming to show that “ Spiroplecta wrightii” is the same as “Textularia sagittula.” We also comes to the conclusion that all species of 7extularia have a spiral beginning, and that the chambers may have been displaced where they are not present. An examina- tion of many species of this genus does not carry out this hypothesis. There are forms that have been placed under Spiroplectammina in which both the megalospheric and microspheric forms have plani- spirally coiled chambers in the end. These have been included under Spiroplectammina. There are, however, a great many species excel- lently preserved both in fossil and Recent material in which the megalospheric form does not show any trace of spiral beginnings. These seem to be distinct from the former group. It may be noted here also that certain of the species referred to J'extularia evidently have their relationship with Gaudryina, and the microspheric form shows traces of a triserial beginning instead of a spiral one. From a strictly phylogenetic point of view, these should be distinguished from the other 7'ewtularia group having their beginning in a spiral form. By acceleration of development the triserial stage has become more and more restricted, and the biserial stage is taken on earlier and earlier. This process may continue until the relationship with Gaudryina is lost entirely, and there may be no possible way of dis- tinguishing textularian forms developed from this source from those that have developed from spiral beginnings.

Test compressed, somewhat longer than broad, composed of numer- ous broad, low chambers, the whole test rapidly increasing in width, especially in the earlier portion, end view narrow, periphery acute, each chamber with the outer margin thickened and coarsely arena- ceous, the early portion concave and much less roughened, so that the surface of the test is composed of an alternating series of raised, rough ridges, and smoother depressions; sutures rather indistinct except for the depressions; wall coarsely arenaceous; aperture nar- row at the inner margin of the last-formed chamber, with a slightly overhanging lip. Length, 0.8 mm.
This species, which has been recorded from a number of stations in the North Pacific and also by Heron-Allen and Earland from the Antarctic, seems to have a wide distribution in the Pacific region. It is nearest to a species described from the Atlantic as Zewxtularia mexicana. 'The microspheric form shows distinct traces of coiling in the early chambers.
The species has been recorded by Hofker from the Zuider Zee, but from his figures his species from the Atlantic is not the same as this one, which is well developed in the Pacific.

Test of medium size, much compressed, triangular, the outer aper- tural end broadly convex; chambers numerous, 9 to 11 on each side in the adult; sutures fairly distinct but only slightly depressed; surface roughly formed, of sand grains so cemented as to leave a characteristic, rough, somewhat flaky surface; aperture fairly large, curved, at the base of the last-formed chamber, with a slight lip. Length, 1 to 1.5 mm.
This species is one of the commonest in the shallow water of the general Indo-Pacific region. It is much compressed and has a char- acteristic size and shape in the adult specimens. When seen with other specimens in the sample it is usually much lighter in color. It is evidently most at home in shallow water of coral-reef regions, and while there are some records from deeper water they are mostly small specimens that may have been easily carried into deeper water. Previous records are by Heron-Allen and Farland from the Kerimba Archipelago, from Timor Sea, Java, 50 fathoms. I have recorded it from seven stations off the Philippines at depths ranging from 20 to 494 fathoms, and from shallow water about Samoa. In the present collections it has occurred at the following localities: Mokaujar Anchorage, Fiji; Viva Anchorage, Fiji, 3 fathoms; Levuka, Fiji, 12 fathoms; Nairai, Fiji, 12 fathoms and 24 fathoms; Vavau Anchorage, Tonga Islands; Rongelap Atoll, Marshall Islands; and from the Guam Anchorage, Ladrone (Marianas) Islands, 21 fathoms. At the last locality specimens are abundant, and the largest in size of any of the localities.
TEXTULARIA FOLIACEA Heron-Allen and Earland OCEANICA, new variety PLaTe 1, Ficures 11, 12
Variety differing from the typical in the much thicker form and rougher appearance of the test. Length of holotype of variety, 2 mm.; width, 1.25 mm.; thickness, 1 mm.
Holotype of variety—Cushman Coll. No. 14667, from Mokaujar Anchorage, Fiji.
This variety is much thicker than the typical, much rougher, and usually of a much darker color. The two occur together at some of the localities, but the variety seems to occur alone at certain others. The holotype is an exceptionally large, fine specimen, much larger

than the usual run of specimens in the collection. In the early stages the variety is usually distinguished by its greater thickness.
Besides the type locality the variety occurs at Levuka, Fiji, 12 fathoms; Nairai, Fiji, 12 fathoms; Vavau Anchorage, Tonga Islands; Rotonga, 7 fathoms; and Port Lotten, Kersail, Caroline Islands.

Test compressed, rather rapidly increasing in width, the periphery rounded, especially in the later chambers; chambers numerous, con- siderably overlapping so that all except the last two are much broader than high from the exterior; sutures distinct, nearly hori- zontal, depressed; wall finely arenaceous, very smoothly finished; aperture at the inner margin of the chamber with a distinct, over- hanging lip. Length, 0.8 mm.; breadth, 0.55-0.7 mm.; thickness, 0.8-0.35 mm.
This species was originally described from the Philippines. Very typical specimens of the broad form occur at Mokaujar Anchorage, Fiji, and a single specimen, apparently the same, from Albatross Station H3901, in 1,620 fathoms, off Marokau Island, Paumotus (Tuamotu Archipelago).

Test elongate, club-shaped, the early portion narrow, much com- pressed, the edges almost carinate, tapering gradually to the rounded apex; chambers numerous, those of the early portion somewhat com- pressed, later ones enlarging very rapidly, and the final ones becom- ing much inflated; sutures of the later portion fairly distinct and considerably oblique, very slightly depressed; wall rather coarsely arenaceous especially in the early portion, often obscuring the sutures; aperture in a broad, shallow sinus at the base of the inner margin of the chamber. Length, up to 1 mm.; breadth, up to 0.6 mm.; thickness, 0.5 mm.
This species is common in the West Indian region, from which it was originally described by d’Orbigny. It occurs also in typical form in the Pacific. It may be distinguished from the following species (agglutinans) by the greater obliquity of the sutures and by the very rapid expansion of the chambers toward the apertural end together with the characteristic roughness of the surface of the early chambers. In the Pacific material examined this species and 7’. agglutinans occur together very rarely, the latter occurring in the Fiji collections but the former apparently absent.
Our records for 7. candeiana include the following localities: Makemo Lagoon, Paumotus; Rangiroa; Rutavu; Port Lotten, Ker- sail, Caroline Islands; Rongelap Atoll, Marshall Islands; Guam Anchorage, Ladrone Islands, 21 fathoms; and the following Alba- tross stations: H8814, latitude 15° 14’ 10’ S., longitude 147° 51’ 05’ W., 391 fathoms off the Paumotus; H3855, off Apataki Island, Paumotus, 654 fathoms; H38889, off Taenge Atoll, Paumotus, 928 fathoms; and H3898, off Hikueru Atoll, Paumotus, 348 fathoms.

right angles to the long axis of the test; wall rather coarsely arena- ceous, but smoothly finished; aperture an elongate slit in a well- marked depression of the inner border of the chamber. Length, 0.8-1 mm.; breadth, 0.5-0.6 mm.
This species was described by d’Orbigny from shore sands of Cuba, and it is a typical species of the general West Indian region, occur- ring in typical form at least as far back as the Miocene in Florida and probably in the West Indies. It is not so common in the Pacific but occurs widely distributed, especially in rather shallow water. It may be distinguished from candeiana by the horizontal sutures, the uniform tapering test, and the rather uniform shape of the cham- bers. In the Pacific collections it has occurred at Albatross Station H3961, off the south coast of Tarawa, Gilbert Islands, 4138 fathoms. In the shallow water material it occurs off the Fiji Islands from Levuka, 12 fathoms, Mokaujar Anchorage. There are typical speci- mens also from Rongelap Atoll, Marshall Islands. It is much less common than candeiana.

Test usually wider than high, triangular in front view, broadly oval in end view, slightly compressed, apex bluntly pointed; cham- bers comparatively few, distinct; sutures distinct, slightly depressed ; wall arenaceous, smooth, or slightly roughened; aperture a narrow slit at the base of the inner margin of the last-formed chamber; color gray. Length, 0.55-0.7 mm.; breadth, 0.55-0.65 mm. ; thickness, 0.4-0.5 mm.
D’Orbigny’s original types of this species were from the West Indies in shallow water, where it is common and widely distributed. It has been recorded from many regions both as a Recent and fossil species, but an examination of the records where figures are given would show that these are not all one species. Various authors have referred the species to Textularia abbreviata d’Orbigny described by him from the Vienna Basin Miocene, but that species in its typical form is very different from the Recent West Indian one. The species occurs in our material from Rangiroa, Paumotus; Vavau Anchorage,

Tonga Islands; Mokaujar Anchorage, Fiji Islands; and from Ron- gelap Atoll, Marshall Islands. There is also a typical specimen from Albatross Station H8930, off Anu Anuraro Atoll, Paumotus, 438 fathoms, evidently a specimen carried out into deep water, as the station is only three-fourths of a mile offshore.

Test short and broad, nearly as broad as long, oval in end view; chambers very distinct, much excavated toward the base, low and broad; sutures deep, usually curved upward in the middle, thence rather sharply downward toward the periphery; wall arenaceous, fine, of rounded particles with considerable cement giving it a smooth finish. Length and breadth, up to 1 mm.; thickness, 0.65-0.75 mm.
Heron-Allen and Earland described this species from Kerimba Archipelago off southeast Africa as a variety of Teatularia conica. While the two forms occur together occasionally in our material they seem to be very distinct. This species is widely distributed, occur- ring off the Fiji Islands in 40 to 50 fathoms, off Rongelap Atoll, Marshall Islands, and Guam Anchorage, Ladrone Islands, in 21 fathoms.

Genotype—By designation, Gaudryina rugosa d’Orbigny.
Test in the early stages triserial, later biserial, transverse section angled or rounded; wall coarsely or finely arenaceous often with a large proportion of cement; aperture, typically a low opening at the base of the inner margin of the chamber, or in the wall of the apertural face. Lower Cretaceous to Recent.
There are a number of species in this Pacific material, and these show very little difference in the relative amount of the test made up by the triserial portion. As already noted under Spiroplectam- mina, textularian forms may easily be developed from Gaudryina and the triserial portion entirely crowded out. All stages in this process can be seen in various species of the genus.

TROPICAL PACIFIC FORAMINIFERA OF ALBATROSS 15
This species was originally described by Bagg from off the Hawaiian Islands. It is now known from numerous stations, espe- cially from the Philippine region and in the North Atlantic. It has proved to be the most common species of the genus in these collec- tions but occurs only in the Albatross material from comparatively deep water as follows: Station H3808, entrance to Avatoru Pass, Rahiroa Atoll, Paumotus, 645 fathoms; H3810, same locality, 661 fathoms; H3959, Ngaruae Pass, Fakarava Atoll, 666 fathoms; H3860, off Fakarava, 602 fathoms; and H38954, off Nomuka Island, Cook Islands, 600 fathoms.
The specimens are uniform in showing the peculiar flaky rough- ness, especially over the earlier chambers, obscuring the sutures to a considerable degree.

GAUDRYINA RUGULOSA, new species PLATE 4, F1cuRES 1 a, D
Test large, stout, somewhat longer than broad, early triserial portion usually confined to the earliest stages, later becoming biserial for most of the growth, periphery broadly rounded; chambers fairly distinct, with the lower side much excavated, sometimes with one or more backwardly directed projections overlapping onto the pre- ceding chamber; sutures distinct, depressed, nearly horizontal or somewhat upwardly curved in the middle; wall arenaceous, but with much cement rather smoothly finished; aperture a low opening at the inner margin of the last-formed chamber. Length, 2 mm.; breadth, 1.85 mm.; thickness, 0.75 mm.
Holotype.—Cushman Coll. No. 14698, from Alofi Niue.
This species has been often recorded from the Indo-Pacific as Textularia rugosa (Reuss). The early stages are, however, triserial, and the species should be placed in Gaudryina. This has been noted by Heron-Allen and Earland in their Kerimba paper, and shown by them in figures in that same paper (pl. 47, figs. 7-9).*
Though the species described by Reuss from the Tertiary from Gaas has apparently chambers that are excavated somewhat at the base, it is certainly not the same as this very large species, so

well developed in the Indo-Pacific in shallow water of coral reefs. Besides the type locality where the species is common and well de- veloped, it has also occurred in the material from Guam Anchorage, Ladrone Islands, 21 fathoms. It occurs in the Philippines, where it is often common and grows to large size.

There is a single large specimen figured here that may be referred to this species. It is from Albatross Station H3816, latitude 15° 16’ 50’’ S., longitude 147° 52’ 30’ W., in 450 fathoms. The typical form of the species is often common in shallow water of the Mediter- ranean, and it is surprising that it has not occurred in many of the shallow-water Pacific samples included in this paper.

tural end, the whole rounded; aperture circular, with a fairly large tooth; color yellowish brown. Length, up to 1.5 mm.
This species was described from Samoa, where it occurred at sev- eral stations. The species has been usually recorded from the Pacific as Clavulina angularis. It is, however, a very different species from that of d’Orbigny and also from C. tricarinata, which is characteristic of the West Indian region. It is apparently not so common in the shallow water of the Pacific as the following species, C. difformis H. B. Brady. Typical specimens of (. pacifica were obtained from Rangiroa and from Makemo Lagoon, Paumotu Islands, specimens from both localities being figured here.

Test elongate, somewhat tapering, usually polygonal, the sides con- cave, early triserial portion short, angles of the test sharp, slightly produced; chambers numerous, distinct, slightly inflated; sutures distinct, depressed, curved; wall arenaceous, rather roughly finished ; aperture circular, with a distinct tooth, the last-formed chamber short and at the apertural end broadly truncate or even slightly de- pressed. Length, up to slightly more than 1 mm.
Brady described this as a variety of Clavulina angularis. It is, however, a distinct species developed in the Indo-Pacific region. The test is typically polygonal in end view, and the wall is very dis- tinctly roughened, the chambers slightly inflated and often having distinct angular projections, which overlap the preceding chamber. Previous records include Nares Harbor, Admiralty Islands (Brady) ; Kerimba Archipelago, southeast coast of Africa (Heron-Allen and Farland) ; Apra Bay, Guam, and Samoa (Cushman). In the present collections typical specimens occurred at Guam Anchorage, Ladrone Islands, 21 fathoms; Mokaujar Anchorage, Fiji Islands, Vavau An- chorage, Tonga Islands; and Makemo Lagoon, Paumotu Archipelago.

Test with the coiling in five planes, the chambers half a coil in length and added successfully in planes 144° apart, five chambers completing a cycle, each chamber 72° from its adjacent one but 144° from the immediately preceding one; wall imperforate, calcareous, often with arenaceous material on the exterior and in deep or brack- ish water occasionally becoming siliceous; aperture usually with a simple tooth.
This is one of the common genera in the shallow water of the South Pacific represented by numerous species. In addition to those recorded here, there are probably several others in our material, but they are represented by either incomplete or insufficient specimens so that specific determination of them is not possible. Some of the species show considerable variation in shape of the chambers and the orna- mentation from the young stages to the adult, and it is necessary to have rather full suites of specimens in order really to understand the complete developmental stages and the adult as well. In order to facilitate use of the species of the genus they are here arranged alphabetically.

somewhat bluntly carinate edges of the test often becoming sinuous; sutures fairly distinct, only slightly if at all depressed; wall smooth or slightly roughened, with minute pits; aperture generally rounded at the end of a distinct neck, and with a single short tooth. Length, 0.6-0.75 mm.; breadth, 0.3-0.4 mm.; thickness, 0.15-0.2 mm.
Many different forms similar to those shown in our figures have been assigned numerous specific names. d’Orbigny’s originals seem to be of the form that has polygonal chambers and a distinctly ex- serted neck. The degree of sinuosity of the edges of the chambers is very variable. Our specimens cover a wide range of territory including a number of Albatross stations, data for which are given in the accompanying table. From our other stations it occurs at Rangiroa; Rutavu; 40 to 50 fathoms off Fiji Islands; Makemo Lagoon; Hereheretue; Pinaki Atoll; Rongelap Atoll, Marshall Islands; Port Lotten, Kersail, Caroline Islands.

Test somewhat longer than broad, periphery squarely truncate or somewhat concave; chambers fairly distinct, rounded or polygonal in transverse section; sutures somewhat obscure; wall composed on the exterior of rather coarse sand grains, but fairly smoothly fin- ished ; aperture somewhat extended with a slight lip and thin plate- like tooth, which extends out beyond the opening. Length, 1 mm.; breadth, 0.6 mm.
This species seems to be identical with that described by d’Orbigny from the West Indian region. I have already recorded it from Samoa. It is, however, not nearly so common in the region as are the other two arenaceous forms. Specimens occurred only off the Fiji Islands; Mokaujar Anchorage, Levuka, 12 fathoms; and Nairai Islands, 12 fathoms.

Miliolina costata Hrron-ALLEN and HARLAND, Trans. Zool. Soc. London, vol. 20, pt. 2, p. 579, pl. 44, figs. 9-12, 1915.
Test elongate, two to three times as long as broad, periphery usually rounded; chambers distinct, inflated; sutures somewhat de- pressed ; wall ornamented by numerous fine longitudinal costae, often slightly oblique to the axis of the chamber; aperture at the end of a short neck, with a slight lip, and single short tooth. Length, 0.35-0.5 mm.; breadth, 0.15-0.25 mm.; thickness, 0.1-0.12 mm.
The types of d’Orbigny’s species are from the Mediterranean. Forms such as those figured here occur rather abundantly in our material from Vavau Anchorage, Tonga Islands, from which the figured specimens came, and from the following Fiji Islands local- ities: 12 fathoms off Levuka; 3 fathoms, Viva Anchorage; Mokaujar Anchorage; and near Nairai. It was also common in 7 fathoms at Rotonga.

Test similar to the typical form in ornamentation but short, and the chambers wedge-shaped, almost sharp at the peripheral angles.
This variety, originally described from the Philippines, occurs widely distributed in the Indo-Pacific and also extends into the Atlantic. ‘
The form is not common in our material, but occurs rarely off Levuka, Fiji Islands, in 12 fathoms; Vavau Anchorage, Tonga Islands, 18 fathoms; off Rotonga, 7 fathoms; Port Lotten, Kersail, Caroline Islands; and Rongelap Atoll, Marshall Islands.

Holotype-—U.S.N.M. No. 14615, from Port Lotten, Kersail, Caro- line Islands.
This is a very peculiarly ornamented species, and it somewhat re- motely resembles the form described and named by d’Orbigny in his Cuban papers as Quingueloculina tricarinata. Our species is, how- ever, apparently quite distinct from d’Orbigny’s, and enough speci- mens were found at the type locality to show that the characters are fairly constant. It has not occurred, however, at any of the other stations.

Our material in the present collections shows that the species is well distributed about the South Pacific Islands, occurring at Mo- kaujar Anchorage, Fiji Islands; off Levuka, Fiji, in 12 fathoms; Vavau Anchorage, Tonga Islands; both in the lagoon and off the ished; aperture rounded or elliptical, with a distinct tooth, some- times bifid at end.

Our figure shows a very elongate specimen, which has a tapering neck with a very distinct phialine lip and circular aperture. Such forms occur at Rangiroa and are somewhat like d’Orbigny’s species, although they seem to be distinct. There are slight traces of longi- tudinal markings, and the wall is polished. Not enough specimens were obtained to be sure of the complete characters.

Quinqueloculina gualtieriana D’ORBIGNY, in De la Sagra, Hist. Fis. Pol. Nat. Cuba, “ Foraminiféres,” p. 186, pl. 11, figs. 1-3, 1839.
Test slightly longer than broad, with the periphery sharply angled and the test tending to become more compressed as the later cham- bers are added; chambers distinct, slightly inflated, broadest toward the basal end, which projects somewhat beyond the general outline of the test; sutures very distinct, depressed; wall smooth and _ pol- ished; aperture rounded or elliptical, with a distinct tooth, sometimes bifid at end. Length, 0.6 mm.; breadth, 0.35 mm.; thickness, 0.25 mm.
This species, described by d’Orbigny from the West Indian region, is present in very typical form in our South Pacific material. In a Jarge series there are a few specimens that seem to show that this species is tending toward Massilina, as occasionally specimens are found in which the last-formed chambers are in a single plane. The whole test is much compressed, as shown in the original figures, and the step to Masstlina would not be a very great one.
Our specimens are from off the Fiji Islands in 12 fathoms, Levuka; 3 fathoms, Viva Anchorage; in 7 fathoms off Rotonga; and most abundant at Vavau Anchorage, Tonga Islands.

Test nearly as broad as long; chambers distinct; sutures slightly depressed; chambers generally triangular in transverse section, the angles subacute but not carinate; wall smooth and polished; aper- tural end of the chamber very slightly extended, forming an ellip- tical neck without a definite lip, but with a narrow elongate tooth. Maximum length, 1 mm.; breadth, 0.8 mm.; thickness, 0.5 mm.
This is a very widely distributed species occurring most commonly in tropical waters, although there are numerous records for it in comparatively deep water. Our specimens, in addition to the Adlba- tross stations, data for which are given in the accompanying table, are from off Fiji Islands, 40 to 50 fathoms; off Nairai, Fiji, 12 to 24 fathoms; off Levuka, Fiji, 12 fathoms; and Viva Anchorage, Fiji, 3 fathoms. The species is common also at Vavau Anchorage, Tonga Islands, in 18 fathoms.

Test about twice as long as broad, periphery subacute; chambers distinct; sutures depressed; surface marked by a series of transverse ridges and alternating excavations not involving the peripheral mar- gin; aperture with a slight lip, rectangular, with a single tooth. Length, 1-1.65 mm.; breadth, 0.6-1 mm.; thickness, 0.4-0.6 mm.
This typically Indo-Pacific species, which from published records has a wide range, occurs rather sparingly in our collections, although it has occurred in few numbers at the following stations: Off the Fiji Islands in 12 fathoms at Levuka, and at Mokaujar Anchorage; in 18 fathoms, Vavau Anchorage, Tonga Islands; Makemo Lagoon, Paumotu Archipelago; Port Lotten, Kersail, Caroline Islands; and Guam Anchorage, Ladrone Islands, in 21 fathoms. Specimens from the last locality are the largest and best developed of all these, and the figured specimens are from there.

very distinct, usually slightly depressed; wall either smooth or more frequently with slight elongate pits covering much of the surface; aperture elongate, somewhat rectangular, but usually narrowest toward the base, toward each a simple narrow tooth extends into the opening. Length, 1-1.3 mm.; breadth, 0.4-0.5 mm.; thickness, 0.2— 0.25 mm.
D’Orbigny described this species originally from the West Indies, from Jamaica and Cuba. The Indo-Pacific specimens seem to show a wide variation the extremes of which seem very distinct, but with a large series these distinctions are usually bridged.
It is one of the commonest species in our collections, occurring off Fiji Islands at Mokaujar Anchorage; 12 fathoms off Levuka; Vavau Anchorage, Tonga Islands; Rutavu; Makemo Lagoon; Pinaki; and beach off wharf Hereheretue. There are also specimens noted in the accompanying table from two Albatross stations.

Quinqueloculina samoaensis CUSHMAN, Carnegie Inst. Washington Publ. 342, p. 59, pl. 21, figs. 4-7, 1924.
Test slightly longer than broad, periphery either squarish in the adult or with a blunt keel in the young, often sinuous; wall thick, with an encrusting of fine sand grains, initial end of the chamber extended and the apertural end elongated slightly into a cylindrical neck with a phialine lip and single tooth. Length, 0.65 mm.; breadth, 0.45 mm.; thickness, 0.3 mm.
This species, originally described from shallow water collections at Samoa, seems to be widely distributed in the collections examined, occurring at the following localities: Mokaujar Anchorage, Fiji; Levuka, Fiji, 12 fathoms; off Nairai, Fiji, 12-24 fathoms; inside the lagoon, Pinaki Atoll, Paumotus; off Rotonga, 7 fathoms; Vavau Anchorage, Tonga Islands, 18 fathoms; off Niau; Port Lotten, Kersail, Caroline Islands; and Guam Anchorage, Ladrone Islands, 21 fathoms.
TROPICAL PACIFIC FORAMINIFERA OF ALBATROSS 27
There is considerable variation in the sinuous character of the chambers, but except for this variation the other characters seem to be generally constant. It may be easily distinguished from either of the other two arenaceous forms which are common in the region.
QUINQUELOCULINA SEMIRETICULOSA, new species
PLATE 7, FIGURES 2 a, Db
Test small, two to three times as long as broad, periphery rounded, the basal end broadly rounded, the apertural end somewhat more contracted; chambers distinct, slightly inflated; sutures slightly depressed; wall beautifully ornamented by a somewhat reticulate pattern, the main elements of which are composed of oblique costae, somewhat irregularly sinuous, the depressed areas between broken up by transverse ridges into a series of elongate pits; aperture very slightly produced, occasionally with a very short neck, the aperture itself nearly circular with a very short, simple tooth. Length, 0.4-0.5 mm.; breadth, 0.2-0.25 mm.; thickness, 0.15-0.2 mm.
Holotype—Cushman Coll. No. 14619, from Port Lotten, Kersail, Caroline Islands.
This seems to be a very beautifully ornamented, localized species, which was fairly common at the type locality but was not seen in any of the other collections.
QUINQUELOCULINA STRIATULA, new species PLATE 7, Ficures 3, 4
Test slightly longer than broad, the periphery of the chambers subacute; chambers triangular in section, distinct; sutures distinct, only slightly depressed; wall ornamented with numerous very fine, incised lines, slightly oblique to the periphery of the chamber, the peripheral angle of the chamber usually smooth; aperture large, broad, with a very slight lip, and a large, fiat tooth nearly filling the aperture. Length, 0.6-0.8 mm.; breadth, 0.55-0.65 mm.; thick- ness, 0.35—0.4 mm.
Holotype—Cushman Coll. No. 14780, from Mokaujar Anchorage, Fiji Islands.
This is abundant at the type locality, and also occurs about Fiji from Viva Anchorage, 3 fathoms; off Levuka, 12 fathoms; off Nairai, 12 fathoms. It is evidently widely distributed in the South Pacific, as we have less abundant specimens from Rotonga, 7 fathoms; Pinaki Islands; Makemo Lagoon; and Rongelap Atoll, Marshall Islands.
This is evidently the same as Afiliolina undulata of Heron-Allen and Earland, not of d’Orbigny, figured in their Kerimba paper

(pl. 48, figs. 5-8).2 A reference to the figures of Quingueloculina undulata d’Orbigny given by Fornasini shows that the species has a rather narrow, elongate aperture, and a very narrow tooth. Speci- mens in my collection from Castel Arquato, Italy, one of the locali- ties mentioned by d’Orbigny, are entirely identical with the original figures of d’Orbigny and show the same type of aperture and general characters of the test, the outer angles of which are not nearly so sharply formed as in our South Pacific species. The figures given by Heron-Allen and Earland show specimens with the same broad aperture and flat tooth that are seen throughout our series. They ~ mention the close relation of their material to Quinqueloculina nussdorfensis d’Orbigny, but topotype material of that species com- pared with the figures shows that it has a narrow tooth and an elon- gate aperture, with the sides truncate. They also mention 7'rélocu- lina brongniartiana d’Orbigny in this connection, but that species as developed in the West Indies is triloculine with a rounded periph- ery, and an exserted neck, making it a very different species from ours.
The material that I have referred to Triloculina suborbicularis d’Orbigny * is also possibly to be referred to this same species.

Test elongate, 214 to 3 times as long as broad, apertural end con- siderably extended out beyond the main body of the test; chambers distinct, elongate, in the early stages with a single angle at the periphery, later becoming truncate with two distinct angles, and in the adult typically with three raised costae; sutures fairly distinct, not much depressed; wall smooth except for the costae; both ends of the last-formed chamber extending beyond the previous chambers, the apertural end tapering with a rounded opening, a definite lip, and a simple tooth, which extends slightly beyond the rim of the aperture in side view. Maximum length, 1.75 mm.; breadth, 0.6 mm.; thickness, 0.8 mm.
D’Orbigny’s original material of this species was from the Red Sea, an area that is closely associated in its fauna with that of the general Indo-Pacific region. Although this species was not really known until the publication of Fornasini’s paper in 1900, it seems

to fit this particular species much better than any of the earlier fig- ures. The development as shown in our series of specimens is inter- esting. Though the neck remains of the same general character throughout and also the general form of the test, the form of the chambers changes greatly from the young to the adult condition, as already noted in the above description.
This is one of the largest species of the genus in the collection and is best developed in the collections from Guam Anchorage, Ladrone Islands, in 21 fathoms. It also occurs off the Fiji Islands at Mokaujar Anchorage and at Rangiroa. There are numerous specimens from various localities that are possibly the young of this species, but where no adults are present to check this they have not been included.

The Miliolina alveoliniformis H. B. Brady described in 1879 is probably the same as Munier-Chalmas’s species, and belongs here. This species is often abundant in shallow-water tropical collections, especially in the Indo-Pacific, but similar forms are also found in shallow warm water in the West Indian region.

Test elongate, fusiform, composed of numerous chambers, long and narrow, five normally visible from the exterior in the early stages, more in the adult; wall in young specimens thin and porcelaneous, in adults covered with sand grains; aperture composed of numerous pores, or radiate, typically cribrate. Length, 1.5-2.2 mm.; breadth, 0.8-1 mm.
The species is abundant in the Fiji Islands at Mokaujar Anchorage, but it has not occurred in the other shallow-water collections. There is a specimen from Albatross Station H3875, half a mile off south- west point of Tahanae, Paumotus, in 269 fathoms. The bottom char- acter at this station is given as coarse coral sand, and this is un- doubtedly a specimen washed out from shallow water. It is sur- prising that this species did not occur at more localities, as it is widely distributed in the Indo-Pacific.

Genotype.—By designation, Quinqueloculina secans d’Orbigny.
Test with the early chambers quinqueloculine, later ones added on opposite sides in a single plane, the quinqueloculine stage present in both megalospheric and microspheric forms; aperture simple, with a bifid tooth.
Some of our specimens show very clearly the development of this genus from Quingueloculina, the early stages being decidedly quin- queloculine, while the later ones progressively add the chambers more and more in a single plane. The genus may be distinguished from Spiroloculina, which has almost all the chambers in a single plane from the beginning, especially in the megalospheric form. In Massilina all the early chambers are quinqueloculine in both the microspheric and megalospheric forms. Species occur in which the exterior is arenaceous, but most of the species have lost that character and are entirely calcareous.

Test much compressed, nearly circular; early chambers quinque- loculine, later ones in a single plane, periphery rounded, chambers distinct; wall of sand grains with a porcelaneous lining to the cham- bers; aperture very slightly exserted. Length, 1 mm.; breadth, 0.9 mm.; thickness, 0.25 mm.
This species, except for a very few records in the Tortugas region off Florida, is known only from the Indo-Pacific, but it is apparently widely distributed in that region. The only material we have in the present collection that can be referred to it is from off Levuka, Fiji Islands, 12 fathoms.
It may be noted here that the Quinqueloculina variabilis of d’Orbigny’s 1826 paper, which came from Rawack, is probably the same as Millett’s species. As the name Quinqueloculina variabilis d’Orbigny remained a nomen nudum until the publication of Forna- sini in 1905, d’Orbigny’s name can not be used for this species.
MASSILINA PLANATA, new species PxLaTE 8, Fiaures 8 a, 6
Test comparatively large, very much compressed, periphery subacute, both ends of the final chamber projecting beyond the body of the test; chambers distinct, much compressed, early ones entirely quinqueloculine, later ones in a single plane; sutures fairly distinct, but very slightly depressed; wall matte, smooth except for very fine elongate pits arranged generally in the long axis of the chamber; aperture elliptical, with a slight lp and an elongate simple tooth, shghtly bifid at the tip. Length of holotype, 2 mm.; breadth, 1 mm.; thickness, 0.2 mm.
Holotype—Cushman Coll. No. 14629, from Guam Anchorage, Ladrone Islands, 21 fathoms.
This is a large striking species that in our material occurred at the type locality only. It suggests rather strongly the specimens re- ferred by Heron-Allen and Earland in their Kerimba Archipelago paper (pl. 41, figs. 1-5)* to Spiroloculina planissima (Lamarck). The early quinqueloculine chambers show that their species belongs to the genus Masstlina and not to Spiroloculina, and its general char- acter suggests that our species is to be found widely distributed in the Indo-Pacific region.

Test longer than broad, compressed, periphery squarely truncate; chambers elongate, of uniform width, quadrangular in transverse section; sutures distinct, very slightly depressed; wall smooth except for numerous fine, linear depressions breaking up the evenness of the surface; aperture rounded, with a sight lip and a definite linear tooth which is slightly bifid at the tip. Length, 1.3 mm.; breadth, 0.6 mm.; thickness, 0.18 mm.
This species was originally described from the north coast of Jamaica at Montego Bay, where it was fairly common. It has not been recorded elsewhere, but very typical specimens occur in our material from Vavau Anchorage, Tonga Islands, which seem to be absolutely identical with the Jamaican specimens.
MASSILINA AUSTRALIS, new species
PLATE 8, FIGURES 2 a, 0D
Test very much compressed, the earliest chambers quinqueloculine, later ones becoming planispiral, with slightly more than two cham- bers making up a coil, periphery subacute; chambers distinct, very slightly inflated; sutures fairly distinct, very slightly depressed be- tween the last-formed chambers, but those of the earlier portion obscured ; wall fairly thin, usually translucent, finely pitted; aperture elongate, narrow, with a slight lip, but no apertural tooth. Diameter, 0.8-1 mm.; thickness, 0.1 mm.
Holotype—U.S.N.M. No. 14625, from Rotonga (=? Rarotonga, Cook Islands), 7 fathoms.
This species is very common at the type locality. It is probably the same as that assigned by some authors to Massilina secans of d’Orbigny. That species, however, in its typical development has a very prominent quinqueloculine stage, and the later chambers have a definite elongate tooth in the aperture. Our series of specimens from the type locality shows that some of the last-formed chambers have a wrinkled appearance as if due to stages of growth of the chamber. The surface is dull and seems to be slightly pitted all over.

The records for this species show that it is rather definitely limited to the Indo-Pacific regions. It is a very distinctive, although small species, and shows little variation in its characters. Specimens are rare in our material, but represent the following localities: Off Fiji Islands in 12 fathoms, Levuka, and Mokaujar Anchorage; near Niau, and Vavau Anchorage, Tonga Islands, 18 fathoms.

Test in its early development quinqueloculine, adult chambers in a single plane, in front view subelliptical, nearly as broad as long, compressed; chambers long and narrow, margin crenulate, due to the regular contractions or plications of the chamber in the adult; aperture rounded. Length, 0.55 mm.; breadth, 0.35 mm.; thickness, 0.08 mm.
This is typically an Indo-Pacific species, but there are rare speci- mens from the West Indian region.
In the present collections the species has occurred at but two stations, at Rangiroa and at Albatross Station H3858, 28° south, 3.5 miles east of Ngaruae Pass, Fakarava Atoll, Paumotus. A specimen from the latter station is figured.

This is a more specialized genus than Masstlina, and the character of having chambers in a single plane is taken on very early even in the microspheric form. In the shallow-water material of the Pacific islands, specimens of this genus are often very abundant but belong to but few species.

cases a pair of such bifid teeth opposite one another; surface of the test dull, somewhat roughened. Length, 1.25 mm.; breadth, 0.6 mm. ; thickness, 0.25 mm.
The typical form of the species is extremely common at some of the South Pacific stations, especially about the Fiji Islands, where it occurs off Levuka, 12 fathoms; Nairai, 12 fathoms; Viva Anchorage, 3 fathoms; and Mokaujar Anchorage; as well as at a station locality not given, but in 40 to 50 fathoms. Besides these Fiji stations 1t occurs at Vavau Anchorage, Tonga Islands; off Rotonga, 7 fathoms; at Port Lotten, Kersail, Caroline Islands; and at Guam Anchorage, Ladrone Islands, 21 fathoms. In the Albatross samples it occurs at Stations H3848, off Point Venus, Tahiti Island, 807 fathoms; H3930, off Anu Anuraro Atoll, Paumotus, 438 fathoms; and H3992, Schisch- marev Pass, Marshall Islands, 482 fathoms.

PLATE 9, F1GuRES 1 a, D
Variety differing from the typical in the peripheral margins which in the variety are beautifully serrate with a series of irregularly shaped teeth.
Holotype of variety—Cushman Coll. No. 14748, from Viva An- chorage, Fiji Islands, in 3 fathoms.
The figured specimen shows the holotype, which has the teeth very well developed along the edges. There seem to be many gradations between this and the form in which these edges are only roughened. The variety was only found at the type locality, but there it is abundant.

Variety with the test elongate, elliptical, much compressed, some- what variably depressed in the middle; chambers distinct, earlier ones rectangular in transverse section, periphery truncate, the angles sharply keeled, later chambers much compressed with a single keel; sutures distinct, little depressed; wall smooth, glossy; apertural end extended into a cylindrical neck and a distinct phialine lip and tooth.
Holotype of variety —Cushman Coll. No. 14747, from off Nairai, Fiji Islands, 24 fathoms.
This variety is very abundant at the type locality, and there are a few other records for it: Mokaujar Anchorage, Fiji; Levuka, Fiji. T have already noted this variety from Samoa. The young stages, which are found with the adults, are very similar to Spzroloculina grateloupi, but as the form develops toward its adult stage there is a very considerable compression of the test, and, in the adult, chambers are developed that are not only compressed but have a definite thin peripheral keel.

Test elongate, elliptical; chambers nearly circular in cross section; surface ornamented by numerous longitudinal costae, often slightly oblique, both ends of the chamber projecting and the intermediate portions thus left either filled by a plate of clear material or occa- sionally open; apertural end projecting and forming a cylindrical neck with a slight lip and a single tooth, sometimes bifid at the tip. Length, 0.55-0.75 mm.; breadth, 0.35-0.4 mm.; thickness, 0.15-0.18 mm.
The original specimens of this species came from off the West Indies and were described by d’Orbigny in 1839. His species was allowed to lapse, and much of the material that should have been recorded as his species has been known under the name of S. grata Terquem, because of the adoption of that name by Brady in the Challenger report for this species of d’Orbigny. As a rule the typi- cal form is more involute than the following variety (angulata), and in the Pacific at least it is much less common. The chambers
TROPICAL PACIFIC FORAMINIFERA OF ALBATROSS aT
are circular in the transverse section in the typical form. Typical specimens occur at the following localities: Off Nairai, Fiji, 24 fathoms; Rutavu; Rangiroa; and at the following Albatross Sta- tions: H3853, Pakaka entrance to Apataki Lagoon, Paumotus, 613 fathoms; H3910, 1 mile off southwest point of Aki Aki, Paumotus, 877 fathoms; H3916, 1 mile off Pinaki Atoll, Paumotus, 486 fathoms; H3983, half a mile off entrance of South Pass, Rongelap Atoll, Marshall Islands, 400 fathoms.

This variety is very much more abundant than the typical form and shows considerable variation, from specimens that are but shghtly angled to those that are very much so. In some specimens there is a contortion of the chambers, and one is here figured (pl. 9, fig. 7) in which the chambers have become arranged three in a coil resembling
Flintina. 'The distribution of the variety is given in the following table:

TROPICAL PACIFIC FORAMINIFERA OF ALBATROSS 39
Chapman described this variety from “forty miles South of Cape Wiles,” and I have had it from material off New Zealand. There is a single specimen from Albatross Station H38992, Schischmarev Pass, Marshall Islands, 482 fathoms, which seems to belong to this variety.

Test broadly elliptical, much compressed, the apertural end ex- tended; chambers of the adult with a sharp translucent keel, usually somewhat lobulated; sutures slightly depressed, surface of the chambers sometimes with irregular, raised costae, more or less oblique in position; aperture at the end of the cylindrical neck, rounded, with a simple tooth; surface smooth, shining, but the wall very thin and brittle. Length, 0.75 mm.; breadth, 0.45 mm.; thickness,
0.1 mm. The only previous locality for this species is the Tortugas off
Florida. It is interesting to find very typical specimens, two of which are here figured from Port Lotten, Kersail, Caroline Islands.

Spiroloculina planissima (LAMARCK) var. samoaensis CUSHMAN, Carnegie Inst. Washington Publ. 342, p. 58, pl. 21, figs. 9, 10, 1924.
Variety differing from the typical in the broader form and the ornamentation consisting of oblique costae running in part way from the border of the test.
This variety, described and figured from Samoa, occurs in very typical form at Vavau Anchorage, Tonga Islands. It apparently is the same as S. striata d’Orbigny, which was named by him in 1826, but not figured until Fornasini gave figures of those species described by d’Orbigny but not figured in the 1826 paper. Meanwhile other authors had used d’Orbigny’s name of striata, so that this is not available for this form, which is probably somewhat widely dis- tributed in the Indo-Pacific, d’Orbigny’s species being from Rawack.

Test elongate, elliptical, periphery convex, the opposite faces con- cave, ends of the chamber projecting; sutures fairly distinct, the outer angle of each chamber projecting above the inner portion of the adjacent next-formed chamber; wall with a granular, dull sur- face; apertural end with a projecting cylindrical neck, circular, with a single, very thin, slightly bifid tooth. Length, 0.5--0.6 mm; breadth, 0.25-0.38 mm; thickness, 0.15-0.18 mm.
This species is not common, but it was found at a number of sta- tions. It is easily distinguished by the partly rounded periphery of the chambers and by the projecting lateral margins originally de- scribed from the Tortugas. It has also been recorded at Samoa and in the present collections occurs off Levuka, Fiji, 12 fathoms; off Nairai, Fiji, 12 and 24 fathoms; Viva Anchorage, 3 fathoms; off Vavau Anchorage, Tonga Islands; and off Rutavu.

This genus has developed from a quinqueloculine ancestry adding the later chambers in a single plane and then reducing the length so that more than two chambers make a coil. With this change in structure is developed a strongly cribrate aperture.
Some of the species, especially Hauerina CRATES TE, are very com- mon in the shallow waters of the Indo-Pacific.

There are numerous records for this species showing its wide dis- tribution in the Indo-Pacific region from Kerimba Archipelago off southeast Africa to the Philippines and southward to Australia. Very similar specimens occur in the lower Oligocene, Byram marl. This is easily confused with the flattened forms of Planispirina, which often occur in the same locality. It may be noted here that the specimens referred to this species in United States National Mu- seum Bulletin 71 (pt. 6, pl. 24, fig. 4, 1917) are not Hauerina, but should be placed in Planispirina.

Test compressed, early chambers milioline, later ones either em- bracing and extending in the center to cover the previously formed chambers or becoming elongate and more or less encircling the periphery; surface ornamented by strong transverse or radial ridges or crenulations crossed by numerous fine longitudinal striae; aperture consisting of numerous small pores in several linear series or scattered, the sieve plate thus formed extending the full height of the chamber. Diameter, up to 1.5 mm.
Although this species is typically an Indo-Pacific one, it occurs sparingly in the West Indian region, but specimens are never so well developed as in the Pacific and Indian Oceans. Forms referable to this species also occur in the Oligocene of the Gulf Coastal Plain of the United States. The types described by Karrer are from the Miocene of Europe.
In our collections the species is often abundant and occurs at the following localities: Levuka, Fiji, 12 fathoms; Mokaujar Anchorage, Fiji; Nairai Islands, Fiji, 12 fathoms; Rotonga, 7 fathoms; Makemo

Test in the early stages quinqueloculine, with strongly angled chambers, in the adult with the chambers somewhat more inflated but carinate and irregularly coiled, more than two making up a coil; sutures fairly distinct in the early portion but not depressed, in the adult much more depressed; wall smooth, matte; aperture somewhat projecting with a slightly convex sieve plate, with numerous irregu- larly arranged pores. Length, 0.7 mm.
The types of this species are from off the Hawaiian Islands in shallow water ranging from 21 to 33 fathoms where it is common. In our material specimens occurred at Guam Anchorage, Ladrone Islands, 21 fathoms, and Mokaujar Anchorage, Fiji Islands.

Test much compressed, the very earliest ones milioline, later ones becoming spiroloculine, and finally, in the last-formed coil, more than two chambers appear, usually three making up a complete coil; wall very finely striate-reticulate; periphery rounded or subcarinate; aperture a sieve plate the entire height of the chamber, curved, with numerous pores. Diameter, 1 mm.; thickness, 0.15 mm.
This is a widely distributed species in the Indo-Pacific. There is a very considerable degree of variation shown by the specimens we have. In the early stages the chambers are in a compact mass of
TROPICAL PACIFIC FORAMINIFERA OF ALBATROSS 45
a generally quinqueloculine character; following these, chambers are developed that fail to make the usual half coil, after which, in the adult, chambers are developed generally in one plane but increasingly shorter so that three or four make up a complete coil. Some of the stages in this development are shown in the figures given here.

Test with the early chambers quinqueloculine or triloculine, later ones in a rectilinear series; aperture in the adult a rounded, usually elliptical opening, at the end of a short neck with a phialine lip.
Lower Eocene to Recent.
This genus has developed from a quinqueloculine ancestry by the addition of a uniserial stage, which is represented only by one or two chambers in some species, but in others these become numerous.

Test much compressed, even in the earlier portion, which is triloc- uline, the later portion consisting of one or two much compressed chambers in linear arrangement, periphery usually keeled; chambers distinct, with numerous fine longitudinal costae; wall translucent,
of a bluish-white color; the aperture with a lip much thickened at the edge, but not everted and not extending out beyond the periphery of the chamber. Length, 0.8 mm.; breadth, 0.3-0.4 mm.; thickness, 0.12-0.15 mm.
Brady’s specimens were from off Kandavu, Fiji Islands, 210 fathoms and 255 fathoms, and he also had it from Raine Island, Torres Strait, 155 fathoms. Brady also recorded the species from off the Bermudas in 435 fathoms, and according to Nuttall the figured specimens in the Challenger report are from this last locality.
I have recorded this species from the West Indian region, but a comparison of the Pacific and the Atlantic series of specimens seems to show that there are decided differences. If the two are found on further study to be different, the name /ineata should be applied to the Atlantic form, as the figured specimens are the Atlantic ones. In the Pacific collections included in the present paper the most numerous are from Mokaujar Anchorage, where it is very common. Similar specimens have occurred also from Levuka, Fiji, in 12 fathoms, but specimens were not obtained from the other area from which material was examined.
ARTICULINA SULCATA Reuss(7?) PLate 11, Fieures 3, 4
Recent material from various regions has been referred to the above species. Specimens consist typically of a quinqueloculine early stage with one or two linear chambers with a decided neck and the surface
48 BULLETIN 161, UNITED STATES NATIONAL MUSEUM
sharply costate. Such forms are widely distributed and seem never to have any considerable number of linear chambers. Reuss’s types were from the Miocene of central Europe and should be compared with the various forms referred to this species from widely separated regions. These specimens figured are from Mokaujar Anchorage, Fiji, and the species occurred also at Albatross Station H3984, off entrance to South Pass, Rongelap, Marshall Islands, in 746 fathoms. This is marked as coarse coral sand and undoubtedly represents material carried out from shallow water.

Test composed of subglobular chambers connected by slender cylin- drical necks; the main body of the chambers with a calcareous base and the exterior composed of rather coarse calcareous fragments of various sorts; the apertural end of each chamber with an elongated tubular neck free from agglutinated material, with a definite lip and a series of platelike teeth inside the lip.
Brady described this species from the following three stations: Humboldt Bay, on the north coast of Papua, 37 fathoms; off Raine Island, Torres Strait, 155 fathoms; and off Tongatabu, Tonga Islands, 18 fathoms.
Although the species has been referred to by numerous authors, most of the specimens from the Indo-Pacific belong to the following variety, which has closely set chambers and a very short neck, and the teeth in the aperture are quite different. The only specimens we have that can be referred to Brady’s species are fragments that are here figured from Nairai, Fiji. They show a characteristic, elongate, small neck and definite lip.

Nubeculina divaricaia (H. B. Brapy) var. advena CusHMAN, Carnegie Inst. Washington Publ. 342, p. 53, pl. 19, figs. 1-4, 1924.
Variety differing from the typical in the closely set chambers, which increase greatly in size and diameter as added; the aperture tubular, but short and stout with a definite everted phialine lip, and very coarse teeth in the opening.
Numerous figured specimens such as those of Sidebottom from the Mediterranean and Heron-Allen and Earland from the Kerimba Archipelago seem to belong to this variety rather than to the typical form. I had this variety in abundance from Samoa, where it reaches a size up to 2.5 mm.
In the present collections it has occurred in typical form from Mokaujar Anchorage, Fiji; off Levuka, Fiji, 12 fathoms; and off Nairai, Fiji, 24 fathoms; with somewhat less typical specimens from off Rotonga (= ? Rarotonga, Cook Islands), 7 fathoms.

Miliolina (part) Wir1AMmson, Rec. Foram. Great Britain, p. 83, 1858 (and later authors).
Genotype.—By designation, Miliola trigonula Lamarck.
Test with the early chambers quinqueloculine, at least in the micro- spheric form, later ones added in the planes 120° from one another, the third of each series added in the plane of the third preceding and covering it so that the surface of the test is composed of but three visible chambers, interior not labyrinthic; aperture simple, typically with a bifid tooth.
This genus is definitely derived from Quinqueloculina by the addi- tion of chambers 120° apart and three making up a complete cycle, and the aperture typically with a bifid tooth. In the microspheric form all the stages are usually present, but in the megalospheric form the early quinqueloculine stages may be entirely skipped and the triloculine stage taken on at once.
In this genus there is a considerable degree of difference in the characters of the aperture. Some of the species have a large semi- circular aperture with a flattened tooth, which nearly fills the aper- ture, while other forms have a narrow aperture with a very narrow tooth typically bifid at the tip. So far as has been noted these two forms are not closely related, but they need further study. In the young stages of the microspheric form chambers are arranged in a quinqueloculine manner, and such specimens can only be determined as the young of 7'riloculina by comparison with the adult form that accompanies them.

It is very evident that more than one species is included in the various references to Montagu’s oblonga. The apertural features show specimens with an elongate, either simple or bifid tooth, to- gether with a somewhat similar form with a flattened tooth nearly filling the aperture. In this South Pacific collection we have lim- ited this species to those forms which have the narrow tooth.

Such specimens occur widely distributed and often are very abun- dant. They occur off Fiji in 40 to 50 fathoms; in 12 to 24 fathoms, off Nairai; in 3 fathoms, Viva Anchorage; 12 fathoms off Levuka; and Mokaujar Anchorage. From other areas the species occurs at Rangiroa; Rutavu; Rotonga; both off the island and from the lagoon at Niau; Port Lotten, Kersail, Caroline Islands; and in 21 fathoms, Guam Anchorage, Ladrone Islands. The data for the Albatross stations are given in the accompanying table.

Test rounded, compressed, the periphery rounded, the three cham- bers making up the visible portion of the test, rounded, inflated; last- formed chamber strongly embracing; sutures distinct, depressed; wall smooth, polished; aperture, a narrow crescentiform slit with a large, flattened, semicircular tooth. Length, 0.4-1 mm.; breadth, 0.38-1 mm.; thickness, 0.2-0.85 mm.
This is one of the commonest species in warm shallow waters, and apparently has a very wide distribution. The general character of a large semicircular platelike tooth nearly filling the large opening is a constant one. The early quinqueloculine stages are usually found accompanying the adult triloculine ones, but are usually of much smaller size.
The accompanying table gives the distribution of this species as found in our collections at the Albatross stations. In addition it has occurred in shoal water inside the lagoon, Pinaki Atoll; Vavau Anchorage, Tonga Islands, 18 fathoms; and off Nairai, Fiji, in 24 fathoms.

Miliolina iabiosa H. B. Brapy, Rep. Voy. Challenger, Zoology, vol. 9, p. 170, pl. 6, figs. 3-5, 1884.
Test much broader than long, surface largely composed of the two last-formed chambers; chambers often somewhat irregular; periphery rounded; surface smooth, but dull; aperture crescentiform, with a somewhat triangular tooth, placed somewhat back from the aperture. Diameter, 0.5-0.65 mm.; thickness, 0.2-0.35 mm.
This somewhat irregular species, originally described by d’Or- bigny from the West Indies occurs in these collections from Ran- giroa; Rutavu; Hereheretue Island; off Fiji, 40 to 50 fathoms; at Mokaujar Anchorage, Fiji; and to the northward at Port Lotten, Kersail, Caroline Islands. At all these stations the material shows
54 BULLETIN 161, UNITED STATES NATIONAL MUSEUM
some variations in the shape of the chambers, which are typically irregular, but the general characters of the aperture and arrange- ment of the chambers remain fairly constant.
TRILOCULINA LABIOSA d@’Orbigny SPARSICOSTATA, new variety
PLATE 12, F1acurEs 1 a—c
Variety differing from the typical in the ornamentation of the sur- face, which has a few, slightly developed, rounding costae with shal. low depressions between.
Holotype of variety—Cushman Coll. No. 14738, from beach off wharf, Hereheretue Island.
This variety is abundant at the type locality and occurs as well with the typical at Rutavu, and a single specimen was taken from Albatross Station H38924, 7 miles northwest of Nukutipipi Atoll, Paumotus.

Test slightly longer than broad, nearly circular in side view, com- pressed, periphery truncate, with the angles produced into definite costae, apertural end slightly extended; chambers distinct; sutures distinct, but not depressed; wall matte, with slightly incised short lines; aperture elongate with a distinct, narrow tooth, with a bifid tip. Length, 0.8 mm.; breadth, 0.5 mm.; thickness, 0.8 mm.
The types of this species described by d’Orbigny are from the Mediterranean. Very similar specimens occur in considerable num- bers in 40 to 50 fathoms off Fiji Islands. In its general characters it somewhat resembles the one here described as 7riloculina oceanica, but the characters of the aperture are very distinctive, and the range of the form with a narrow aperture is very limited.
TRILOCULINA OCEANICA, new species
PLATE 12, Figures 3 a—c
Test about as long as broad, the periphery concave with very prominent angles to the chambers, which are acute; sutures distinct, slightly depressed; wall smooth except for the very coarse costae and angles of the chambers; aperture large, with a semicircular, flattened tooth nearly filling the opening. Length, 0.5-0.6 mm.; breadth, 0.45-0.5 mm.; thickness, 0.3-0.35 mm.

Holotype-—U.S.N.M. No. 22078, from Albatross Station H3935, 1 mile west of Hereheretue Atoll, Paumotus.
This species, with its large flat tooth and broad, semicircular open- ing with the acutely angled chambers, seems to be a distinct one in fairly deep water among the islands of the South Pacific. There are specimens from Pinaki Atoll and from the beach off the wharf at Hereheretue. It occurs also at a number of Albatross stations, the data for which are given in the accompanying table.

PLATE 12, Ficures 4 a—c
Variety differing from the typical in the ornamentation of the surface, which consists of numerous additional fine costae, especially on the periphery, in addition to the angles of the chambers.
Holotype of variety —U.S.N.M. No. 22089, from Albatross Station H8857, one-half mile east of Center Tikei Island, Paumotus.
This variety is evidently closely allied to the species, but seems to be worth a distinction from the smoother form.

Test subcircular in front view, somewhat compressed, periphery rounded; chambers distinct; sutures slightly depressed; wall orna- mented by numerous longitudinal costae; aperture semicircular, with a slight tooth, which in side view projects beyond the outline of the aperture, and sometimes shows a distinct perforation. Diameter, 0.55-0.8 mm.; thickness, 0.4-0.45 mm.
This is one of the typical West Indian species described by d’Orbigny from Cuba and Jamaica. There are numerous records for it in the general West Indian region, and our material shows that it extends definitely into the Indo-Pacific, although much of the material that has been referred to this species is not the same as the species described by d’Orbigny. The only typical material we have is from Guam Anchorage, Ladrone Islands, 21 fathoms, one of which is here figured.
TRILOCULINA SPINATA, new species
PLATE 12, FIGURES 5 a—c
Test elongate, fusiform, periphery rounded, the basal end extend- ing into a definite pointed spine, the apertural end extended into a long cylindrical neck; chambers distinct, somewhat inflated; sutures distinct, not depressed; wall smooth; aperture circular with a very slight lip and a very small simple tooth, which may or may not be present. Length, 0.6 mm.; breadth, 0.12 mm.; thickness, 0.1 mm.
Holotype-—Cushman Coll. No. 14633, from Rongelap Atoll, Mar- shall Islands.
This very distinctive species occurs only at the type locality, but a number of specimens were present to give the full characters of the species, which were very constant. The spine at the basal end is very well developed and is a rather unique feature in this group.

wide, in end view rounded, triangular, the sides convex; sutures dis- tinct; wall smooth; aperture with a rather broad bifid tooth. Length, 0.5-0.85 mm.; diameter, 0.4-0.45 mm.
As noted previously in Bulletin 104, Lamarck’s type of this spe- cies is from the Eocene of the Paris Basin, and before the applica- tion of this name can be very definitely and accurately used it would be necessary to make sections of microspheric specimens to determine the characters of the early stages. It has been the usual custom for authors to place under this species almost any of the triangular forms that have the edges rounded.
Such specimens as that figured here are fairly common in our material occurring off Fiji at Mokaujar Anchorage; 12 fathoms off Nairai; 12 fathoms off Levuka; and also from Makemo beach and Rutavu, as well as a specimen from Albatross Station H3936, 0.3 mile east of Hereheretue Atoll, Paumotus.

Triloculina austriaca DORBIGNY, Foram. Foss. Bass, Tert. Vienne, p. 275, pl. 16, figs. 25-27, 1846.
Test slightly longer than broad, generally triangular in transverse section, the sides and periphery of the chambers rounded; chambers distinct, inflated, usually broader at the base than at the apertural end, giving an asymmetrical shape to the test in front and side views; sutures distinct, slightly depressed; wall smooth and polished, but often marked by very slight elongate pits; aperture either rounded or somewhat modified as shown in the accompanying figures, with an elongate tooth bifid at the tip, apertural lip thin and slightly everted. Length, 0.7 mm.; breadth, 0.45 mm.; thickness, 0.4 mm.
A number of the species described by d’Orbigny from the Miocene of the Vienna Basin are found still living in the Indo-Pacific region

as well as in the Mediterranean. Our material fits very well the form described by d’Orbigny, which we have from the type locality. It differs from 7’. trigonula in the side view on account of the greater inflation of the base, and the chamber is not symmetrical as it is in T. trigonula. The aperture also is distinctive. Those specimens that do not have a circular aperture have the sides toward the base with definite thin lobes, which are difficult to describe but which are shown in the accompanying figures.
So far as our material shows this species seems to have very definite and restricted distribution. It is abundant in the collections from the Paumotu Islands, occurring both inside the lagoon and off the island of Rongiroa; from the beach off wharf, Hereheretue; on the outer beach and in the lagoon at Pinaki Island.
Similar specimens occurred at a few Albatross stations, all also off the Paumotu Islands as shown in the accompanying table.
TRILOCULINA AFFINIS d’Orbigny PLATE 13, Ficurss 4 a, DB

Test slightly longer than broad, triangular in transverse section, the angles subacute and the outer wall of the chamber decidedly con- vex; sutures distinct, slightly if at all depressed; wall smooth; aper- ture generally circular, with a distinctly bifid tooth. Length, 0.35- 0.45 mm.; breadth, 0.35-0.4 mm.
The types of this species were from the Miocene of Dax in the Bordeaux region. Terquem records a somewhat similar form under this name, and Fornasini reproduced outline figures from d’Orbig- ny’s plates. An examination of the Miocene material from the type locality of Dax shows that there are forms present there that strongly suggest that this species is closely related to the forms here called Triloculina trigonula. The outer periphery is distinctly convex, al- though the peripheral angles are often rather sharply formed.
Such specimens occurred at a number of stations as follows: Mokaujar Anchorage, Fiji; Viva Anchorage, 3 fathoms, Fiji; Le- vuka, 12 fathoms, Fiji; near Nairai, Fiji; Rotonga, 7 fathoms; Makemo Lagoon; and in 21 fathoms off Guam Anchorage, Ladrone Islands. It occurred also at several Albatross stations as noted in Table 19.

Miliolina tricarinata H. B. Brapy, Rep. Voy. Challenger, Zoology, vol. 9, p. 165, pl. 3, figs. 17 a, 6b, 1884.
Test in the adult with three visible chambers, the angles of the chambers sharp, often almost carinate, whole test usually somewhat longer than wide, in end view triangular, the sides straight; sutures distinct; wall smooth, often polished; aperture with a narrow bifid tooth or variously angled in large specimens. Maximum length of our specimens, 0.6 mm.; diameter, 0.45 mm.
As noted previously, this species, also like affinis, needs definite sections to determine its early stages in relationships. I have in- cluded here only those specimens that have very sharp angles and the sides flat or slightly concave. There is apparently a difference in the distribution between this and affinis, our specimens being mostly from Albatross stations in deeper water, although rare specimens have occurred at Mokaujar Anchorage; Vavau Anchorage, Tonga, in 18 fathoms; and at Rongelap Atoll, Marshall Islands.
Although there are a great many references to this species, they are not given here, as so many things have been included under this name that probably are not strictly to be included under one species.

Test longer than broad, triloculine, typically with the chambers with a truncate periphery, the angles somewhat extended; cham- bers distinct; sutures somewhat depressed; surface ornamented by reticulations both on the sides and on the outer angles; aperture elongate, with a definite thin lip, shghtly everted, tooth elongate, narrow, extending above the outline of the aperture. Length, 0.8-1 mm.; breadth, 0.7-0.9 mm; thickness, 0.55-0.6 mm.
The reticulately ornamented species have been noted under many different names since the earliest ones given by d’Orbigny. D’Or- bigny’s Triloculina reticulata was not figured in the 1826 paper, and while it may apply to various forms with a rounded periphery such as those to which Brady assigned the name in the Challenger report, our specimens with definitely angled chambers are much closer to the West Indian species described by d’Orbigny in 1839 as Triloculina bicarinata.
Our specimens are all from Mokaujar Anchorage, Fiji, where this form is very abundant, but it was not found in any of the other stations. There is as usual a considerable degree of variation in size and arrangement of the reticulations, and in these Fiji speci- mens the peripheral face of the chambers is highly ornamented, while the sides are much less so.
TRILOCULINA sp. (7)
PLATE 13, FIGURES 7 a-c
There are in the collections certain forms similar to that here figured that are very difficult to place specifically. The species seems to be on the border line between Z7riloculina and Quingueloculina, and it is figured here in order that attention may be called to this peculiar form.

In its microspheric form this genus shows all three stages—quin- queloculine, triloculine, and biloculine—but in the specimens with a small megalospheric proloculum acceleration takes place and the quinqueloculine stage is skipped, and in specimens with a very large proloculum the biloculine character is taken on at once and both the quinqueloculine and triloculine stages are skipped entirely.

A number of the species of this genus have become adapted to a cold, deep-water habitat, an unusual one for most of the genera of this family.
In the shallow water of the Pacific the genus is often very abundant, but is limited to a very few species.

Test elongate, roughly quadrangular in front view, in end view somewhat compressed, biconvex, apertural end broadly rounded, opposite end with a series of short, irregular teeth; wall smooth, us- ually polished; aperture very broad and narrow, extending nearly the whole width of the test, the ends somewhat expanded, with a long, narrow tooth, making the inner border of the aperture platelike, somewhat raised above the level of the surface to which it is attached, as is the whole border of the aperture. Length, 0.6-1 mm.; breadth, 0.45-0.9 mm.; thickness, 0.3-0.5 mm.
This is a typical species of the Indo-Pacific usually most abundant in coral reef regions. There are numerous records for it from shal- low water in various parts of the Pacific from the Philippines to the Hawaiian Islands, southward through the various groups of islands, and westward to the coast of Africa. It also occurs in much less abundance and is less well developed in the Atlantic. It is by far the most common species of the genus in the material we have examined from the South Pacific. There is a great deal of variation in this species, and some of the various forms are figured here. The young stage is very close to Pyrgo elongata in many ways, and it is these small light forms that are most easily carried out into deep water by the current and are found at a number of Albatross stations a short distance away from these islands, as will be noted. The figures give these early stages, which may be compared with the adults. Not all

Some of those with well-developed teeth are here figured as well as the smooth forms. In these collections the species occurs in typical form at the following localities: Mokaujar Anchorage, Fiji; Nairai, Fiji, 24 fathoms; Levuka, Fiji, 12 fathoms; Vavau Anchorage, Tonga Islands, 18 fathoms; Rongelap Atoll, Marshall Islands; Guam An- chorage, Ladrone Islands, 21 fathoms; Rutavu; and at the following Albatross Stations: H8857, one-half mile off Center Tikei Islands, 360 fathoms; H3858, Ngaruae Pass, Fakarava Atoll, 599 fathoms; H3916, 1 mile off Pinaki Atoll, 486 fathoms; H3935, 1 mile off Here- heretue Atoll, 594 fathoms; H3936, same locality, 189 fathoms; all off Paumotu Islands; and H3967, one-half mile off Maraki Atoll, Mar- shall Islands, 431 fathoms,

Specimens that seem to be the same as the specimens described by
Bornemann from the Oligocene of Europe, and recorded by Schlum-
berger from off the Azores, are found at numerous stations in the
Albatross collections but not in the shallow-water samples. The
typical form has a flat tooth largely filling the aperture. The speci-
mens figured from the Philippines do not have this typical tooth but are otherwise similar.

Test with a globular proloculum followed by a planispiral tubular second chamber, the adult chambers in a rectilinear series; aperture simple, with a lip.
Lias to Recent.
This genus was apparently developed early in the history of the family, and species and specimens are common in the Jurassic. There are few living species.
The early stages in most specimens are very delicate, and easily broken away so that the majority of specimens have only the later heavy-walled chambers present. In some specimens there is only the proloculum and a second coiled chamber before the rectilinear series is taken on. In others there are two or three coiled chambers usually making up a half coil or less, but the proloculum is always evident. This is a typically tropical shallow-water genus. Owing to the early chambers being usually lacking, it is difficult to place some of the early described species, such as, for example, the forms usually re- ferred to Articulina conico-articulata. The original figure given by Batsch does not have the early chambers, and it is very difficult to be sure of his species.
NODOBACULARIA ANTILLARUM Cushman PACIFICA, new variety
PLATE 16, FiagurEs 1 a—c

Length, 2.2 mm.; breadth, 0.2 mm.

Holotype of variety—Cushman Coll. No. 14741, from Mokaujar Anchorage, Fiji.
This variety has also occurred off Levuka, Fiji, in 12 fathoms, and off Nairai, Fiji, 12 fathoms. Somewhat less typical specimens, but probably belonging to this same variety, occurred off Rotonga, 7 fathoms, and at Vavau Anchorage, Tonga Islands, 18 fathoms.
It is close to the species I have described as Nodobacularia antil- larwm from the West Indian region. The Pacific specimens, how- ever, uniformly have more and sharper costae, and the earliest cham- bers are more compressed and smaller in comparison with the adult chambers.

Test with the early chambers planispiral, the later ones rectilinear and rapidly increasing in size as added, adult chambers very strongly pyriform, greatest breadth at the base, and thence rather rapidly contracting toward the apertural end, which is expanded into a broad smooth lip; sutures distinct; wall ornamented by a few, 12 to 18 usually, high, thin, platelike costae, which terminate in spines at the basal end, those of the later chambers often bifurcating; aperture elliptical, with a very broad lip. Length, 1.5 mm.; breadth, 0.5 mm.; thickness, 0.35 mm.
Holotype——Cushman Coll. No, 14743, from Mokaujar Anchorage, Fiji.
This is probably the same form as that described and figured by Millett in the above reference from the Malay Archipelago. His specimens, however, show a much larger proloculum, and the coiled chambers show practically no compression, while in our speci- mens from Fiji there is a strongly compressed young stage. Later chambers, however, seem to be very close to ours. It may be that his specimens are the megalospheric form, while ours are micro- spheric. This is a fine distinctive species, beautifully ornamented, and so far as the material we have shows, has only occurred off Fiji at Mokaujar Anchorage, and off Levuka in 12 fathoms. It is common at the type locality.
In the early stages there may be developed short chambers of one- third of a coil in length, which begin to take on the characteristic costz ornamentation before the adult uniserial stage is developed.

This is a small easily overlooked species occurring in its typical form rather widely distributed in the Indo-Pacific, although there are records from other regions. I have in the present collections very typical specimens from 12 fathoms off Levuka, Fiji, where it is fairly common, and from near Nairai, Fiji. A single specimen also occurred at Albatross Station H3812, 714 miles south of entrance, Avatoru Pass, Rahiroa Atoll, Paumotus.

Test minute, generally oval in outline, biconvex, consisting of a few milioline chambers, the apertural end somewhat extended, turned so that the aperture is entirely at one side of the test; aperture elliptical or rounded, with a broad, flaring lip; sutures fairly dis- tinct, not depressed; wall translucent; color, bluish white. Length, 0.3 mm.; breadth, 0.15 mm.; thickness, 0.05 mm.
The only specimens we have are a few from Port Lotten, Kersail, Caroline Islands,
This minute species is, like the preceding, very easily overlooked on account of its small size. From the records, however, it has a wide distribution in both the Atlantic and Pacific. It is easily distin- guished by the large aperture in proportion to the size of the test, and the fiaring lip.

Test much compressed, early portion close coiled, later uncoiling in a series of low, broad, uniserial chambers; sutures distinct, de- pressed; surface ornamented by fine longitudinal striae; aperture elongate, irregular, the lip on one side being shorter than on the other, making the aperture really on the ventral side of the test, lip smooth, ends rounded and not projecting. Length, 0.6-1.2 mm.; breadth, 0.5-0.7 mm.; thickness, 0.2-0.25 mm.
This is a common species in the material, rather widely distributed, and while it varies somewhat in form, because the early stages are close coiled and the later ones somewhat uncoiled, nevertheless the ornamentation, which is very constant, will serve to distinguish the species from any other of those allied to it. There are occa- sional specimens that tend toward V. reticulosa Cushman described from the Philippines, but none of them has these characters very strongly developed. D’Orbigny’s model of this species shows a much uncoiled specimen with the sides in the adult nearly parallel. Such specimens are not common, but are occasionally found in large series of specimens. Most of those found are usually in the early coiled stages. There are specimens in the present collection from Mokaujar Anchorage, Fiji; Levuka, Fiji, 12 fathoms; Viva Anchorage, Fiji, 3 fathoms; and off Nairai, Fiji, 12 fathoms. Specimens also occur off Vavau Anchorage, Tonga Islands; off Rotonga (= ?Rarotonga) ; and Guam Anchorage, Ladrone Islands, in 21 fathoms.

TROPICAL PACIFIC FORAMINIFERA OF ALBATROSS wo
This species seems to be widely distributed in warm coral reef areas, especially in the Mediterranean and the Indo-Pacific. It is an extremely variable form, and assumes many shapes.
Our specimens are all from comparatively shallow waters, except for one station off Fiji in 21 fathoms or less. They include the fol- lowing stations: Off Nairai, Fiji, 12 fathoms; off Levuka, Fiji, 12 fathoms; off Fiji, 40-50 fathoms; Rangiroa; off Niau; Makemo Lagoon; beach off wharf, Hereheretue Island; Rutavu; Vavau An- chorage, Tonga Islands, 18 fathoms; Port Lotten, Kersail, Caroline Islands; and Guam Anchorage, Ladrone Islands, in 21 fathoms.
Family FISCHERINIDAE
Test coiled, earlier ones somewhat planispiral, later ones trochoid, all coils visible from the dorsal side, only the last-formed one from the ventral side; chambers distinct but not inflated, usually four or five making up the last-formed coil; wall calcareous, imperforate; aperture rounded, formed by the open end of the last-formed chamber.
This family is represented by the single genus Fischerina, which is commonest in the warm waters of the Tropics. The family is closely related to and derived from the family Ophthalmidiidae. It is a direct derivative of the genus Cornuspira, assumes a trochoid form, and is divided into chambers.

Test coiled in a low conical spiral; chambers few in each coil, all visible from the dorsal side, only those of the last-formed coil from the ventral side; wall calcareous, imperforate; aperture formed by the open end of the last-formed chamber, simple.
The species of this genus are mostly confined to shallow warm water of the Tropics.
Our material has yielded three species of this genus, all of them apparently different from the West Indian one.

Test forming a very low, compressed, trochoid spiral of only about 114 to 2 whorls, the earliest portion in the microspheric form with the chamber following the proloculum, making about one complete coil, followed by an adult whorl, in which there are from 5 to 6 cham- bers on the dorsal side, the coils very slightly if at all overlapping, on the ventral side the central portion slightly umbilicate, the last- formed whorl making up most of the surface on the ventral side, periphery broadly rounded; wall thin, translucent, bluish white; aperture circular, formed by the open end of the last-formed chamber. Diameter, 0.25 mm.; thickness, 0.05-0.07 mm.
Millett’s types of this species are from the Malay Archipelago, and there are records for it, references to which are given above, from the Kerimba Archipelago (Heron-Allen and Earland) ; off New Zea- land, off Samoa (Cushman) ; Lord Howe Island (Heron-Allen and Earland). Rather typical specimens occurred in our material from Port Lotten, Kersail, Caroline Islands, and from Guam Anchorage, Ladrone Islands, in 21 fathoms.

Test forming a definite trochoid spiral of 4 or 5 volutions, pe- riphery broadly rounded, whorls with about 3 or 4 chambers to each; sutures flush with the surface except the spiral suture, which is somewhat depressed; wall very thin, fragile, opalescent; aperture formed by the open end of the last-formed chamber. Diameter, 0.25-0.8 mm.; height, 0.18-0.2 mm.
Heron-Allen and Earland described this species from the Kerimba Archipelago off southeast Africa, and also recorded it from a dredging off the Poor Knights Islands, New Zealand. The only material I have had in these present collections is 40 to 50 fathoms off Fiji.

Test nearly planispiral and almost completely involute on both sides; chambers somewhat indistinct, three or four in the final whorl; sutures sigmoid on the ventral side, on the dorsal side radial, flush with the surface; wall very thin, fragile; aperture semicircular, formed by the open end of the last-formed chamber. Diameter, 0.3-0.35 mm.; thickness, 0.2 mm.
TROPICAL PACIFIC FORAMINIFERA OF ALBATROSS 77
Holotype —uvU.S.N.M. No. 14626, from Rangiroa.
This species differs from the other known ones of the genus in having the whorls almost completely involute, especially in the later development. A few specimens seem to show that the earliest cham- bers are more open. The ventral side seems to be almost completely involute with a very slight umbilical depression, the dorsal side flattened or slightly convex. As far as our material shows, this is the commonest species of the genus in the South Pacific. It is abundant at the type locality, and also occurs at Rutavu; Makemo Lagoon, Paumotus; inside lagoon, Pinaki Atoll; beach off wharf, Hereheretue; and from Albatross Station H3933, latitude 20° 02’ S., longitude 144° 28’ W., Paumotus.

NOURIA POLYMORPHINOIDES Heron-Allen and Earland PLATE 17, Fiaures 9 a, 0
Nouria polymorphinoides HrRon-ALLEN and HAriAnp, Trans. Zool. Soc. London, vol. 20, pt. 12, p. 376, pl. 37, figs. 1-14, 1914; pt. 17, p. 615, 1915 —CusHMan, Proc. U. 8S. Nat. Mus., vol. 56, p. 601, pl. 75, figs. 4, 5, 1919.—HERoN-ALLEN and EARLAND, British Antarctic Expedition, Zoology, vol. 6, p. 103, 1922.— CusHMAN, Contr. Cushman Lab. Foram. Res., vol. 3, p. 189, 1927; Bull. Seripps Inst. Oceanogr., Tech. Ser., vol. 1, p. 142, 1927.
This species has now been recorded from several widely distributed stations in the Indo-Pacific region from the east coast of Africa, the western coast of America, and from off New Zealand. The record given by Heron-Allen and Earland from the Eocene of Biar- ritz® seems from the figures to be a different thing. The Indo- Pacific material is definite in its general characters. Our specimens are from Mokaujar Anchorage, Fiji, in comparatively shallow water. They often have sponge spicules incorporated in the test as well as other fragments of various sorts. These are usually neatly cemented, and there are traces of sutures in most of the specimens.
