THE FORAMINIFERA OF THE TROPICAL PACIFIC COLLECTIONS OF THE “ALBATROSS,” 1899-1900

Part 3.—HETEROHELICIDAE AND BULIMINIDAE

By JosrpH AUGUSTINE CUSHMAN

INTRODUCTION

THIS PAPER is the third part of a work the intent of which is to de- scribe 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. Part 4 will complete the work and will take up in systematic order the families beginning with the Rotaliidae. Readers are referred to Part 1, p. 3, for a map showing the general route of the Albatross through the South Pacific.

Some interesting relationships have been noted in these faunas in which are living representatives of species known hitherto only from the late Tertiary of other regions. The number of distinctive species in this area is large, which is not surprising when the remoteness from other shallow-water material is taken into consideration and also the very small amount of work that has been done on the deeper-water deposits of the Pacific region.

Japan, vol. 45, No. 538, p. 607, pl. 16 (5), fig. 17, 1938.

Test elongate, slender, very slightly tapering, in end view quadri- lateral, the angles usually carinate; chambers high and narrow, run- ning back obliquely on the outer border, compressed; the initial end of the test often with a stout spine, occasionally with several small spines or smooth and broadly rounded, the early chambers sometimes with one or more longitudinal raised costae for a short distance; wall hyaline, distinctly perforate; aperture at one side near the distal end of the chamber, sometimes obliquely elongate, but somewhat varia- ble. Length, up to 1.25 mm.

This species was originally described from the Pliocene of Kar Nico- bar by Schwager. It is a characteristic species of the present Indo- Pacific region although it apparently also occurs in the Atlantic. The Atlantic specimens, however, as a rule seem to lack the basal spine, and it may be that other differences may make it possible to separate the Atlantic form. In the present collections this species has occurred almost entirely at Albatross stations, the data for which will be found in table 2. In addition it has occurred at 3 fathoms, Viva Anchorage, Fiji, and at 12 fathoms off Levuka, Fiji. At some of the Albatross stations, as will be noted, the species is relatively abundant.

Test free, very much compressed, broad and triangular in front view, the apertural end usually broadly convex, in end view narrow, widest near the middle, thence tapering toward the rather acute lateral mar- gins; chambers broad and low in the adult, in two alternating series, somewhat curved; sutures thickened, in the later portion usually somewhat sigmoid, median line with a slightly raised median suture; wall rather coarsely perforate; proloculum rounded or quadrangular, periphery often with spines at the outer angles or sometimes at the sides, independent of the individual chambers. Length, usually not more than 0.50 mm.

This is one of the typical Indo-Pacific species especially in the warm shallow waters of coral reefs. There are numerous records for the Indo-Pacific as follows: Shore sand, Melbourne (Parker and Jones); Mauritius, rare, from the intestine of Maretia planulata (Moebius) ; off East Moncoeur Island, Bass Strait, 38 fathoms; off Raine Island, Torres Strait, 155 fathoms; off Kandavu, Fiji, 255 fathoms; off Levuka, Fiji; Nares Harbor, Admiralty Islands, 17 fathoms; Honolulu coral reefs, 40 fathoms (H. B. Brady) ; Mauritius and East Australia (Egger) ; from the lagoon at Funafuti; shore sands of Victoria (Chapman); shallow water off Laysan Island (Rhumbler); off the Hawaiian Islands, 305 fathoms (Bagg), 249 and 271 fathoms (Cushman); a single specimen from the Kerimba Archipelago, 5-10 fathoms (Heron- Allen and Earland); Lord Howe Island (Heron-Allen and Earland);a single specimen, Philippines; and Hawaii to Midway Island (Cush-

man). In addition to the above localities the species has occurred at several Albatross stations, data for which are given in table 3. It has also been found to be common in shallow water at the following stations about the Fiji Islands: Off Nairai, 12 and 24 fathoms; off Levuka, 12 fathoms; and Mokaujar Anchorage. There are also abun- dant specimens from Makemo Lagoon, Paumotu Islands. It seems strange that the species should be absent from the shoal-water collec- tions of some of the other regions that are represented by material, such as the Marshall Islands and Ladrone Islands.

Bolivinella folia (PARKER and JONES) var. ornata CusHMaN, Contr. Cushman Lab. Foram. Res., vol. 5, p. 32, pl. 5, figs. 3, 4, 1929.

Test somewhat similar to the typical form but the apertural end much more convex, typically with a large stout spine at either side, the sutures broadly limbate and raised throughout into a fine beaded ornamentation, the median line slightly raised but not markedly so.

This variety was originally described from the shore sand of Hard- wicke Bay, Australia. There is a single specimen in our collections from 12 fathoms off Levuka, Fiji, and it has not occurred elsewhere.

BOLIVINELLA MARGARITACEA Cushman PuLaTH 2, FIGURE 7

Bolivinella margaritacea CusHMAN, Contr. Cushman Lab. Foram. Res., vol. 5, p. 33, pl. 5, fig. 5, 1929.

Test elongate, whole test very gradually broadening as chambers are added, sides usually irregularly indented and with irregular spinose projections of small size or wanting; chambers gently curved, the last one slightly sigmoid; sutures limbate, slightly raised, the earlier ones only slightly curved, later ones tending to become sig- moid and irregularly beaded, median line with a very slightly chan- neled ridge. Length, 0.40 mm.; breadth, 0.20 mm.

This species was described from the Miocene of France, the fauna of which is related in many ways to the present Indo-Pacific fauna. It is, therefore, not surprising that a typical specimen, which is here figured, appears in the material from Rutavu.

PLATE 2, Figure 11

Nodogenerina spinata CusaMAN, B. P. Bishop Mus. Bull. 119, p. 123, pl. 14, fir. 14, 1934.

Test elongate, very rapidly tapering from the somewhat rounded base; most of the chambers of the same diameter or even slightly smaller toward the apertural end, inflated; sutures distinct, depressed; wall calcareous, finely perforate, ornamented with numerous spines projecting backward and more abundant on the lower half of the chamber; aperture rounded, at the end of an elongate neck which has a slight lip.

Holotype (Bishop Museum No. 1308) from the late Tertiary of Fiji.

We have from Albatross station H3866, lat. 17°17’00’’ S., long. 145°45’30’" W., in 804 fathoms, glob. oz. mang., a single typical specimen of this species, which is here figured. Its distribution must, therefore, be very greatly restricted, occurring in the late Tertiary and still living off Fiji.

Nodogenerina milletti CusHman, Contr. Cushman Lab. Foram. Res., vol. 9, p. 86, pl. 8, figs. 17, 18, 1933.

Test elongate, tapering rapidly from the somewhat narrow base, greatest breadth in the adult specimens near the middle, and later chambers somewhat reduced in size; chambers numerous, those of the early portion not inflated, later ones much inflated and excavated at the base forming a distinct ridge about that portion; sutures distinct, depressed especially in the later portion; wall calcareous, perforate, ornamented by very fine longitudinal costae which tend to break up into fine rows of papillae; aperture rounded, at the end of a slight neck but without a definite lip. Length, 0.70 mm.; breadth, 0.20 mm.

The holotype is from 21 fathoms, Guam Anchorage, Ladrone Is- lands. The only other records for this species are those given by Millett from the Malay region. This is not the same as Parker and Jones’ species, and the generic position of it is very much in

TROPICAL PACIFIC FORAMINIFERA OF “ALBATROSS” 7

doubt. Millett figures some very strange forms with lobed chambers and the early portions possibly not entirely uniserial. Our specimens have been too few to warrant the making of sections to determine the structure of this early part, and this generic position must remain doubtful until sufficient material can be obtained for sectioning.

Test small, tapering, initial end bluntly rounded, increasing in diameter toward the apertural end, consisting of two or three whorls; chambers distinct, four or more making up the last whorl, slightly inflated; sutures distinct, flush with the surface or slightly depressed, especially the spiral suture, slightly limbate; wall smooth, very finely perforate; aperture a semielliptical opening at the base of the apertural face which is broadly rounded with slight ridges running into the depressed area at the center. Length, 0.30 mm.; diameter, 0.15— 0.20 mm.

The types are from Mokaujar Anchorage, Fiji. The species occurs at various localities in the Fiji Islands, Pago Pago Harbor, Samoa, Zanzibar, Montego Bay, Jamaica, the Dry Tortugas, and St. Johns, Antigua. It has been reported by Sidebottom from the Island of Delos. The species also occurs in the shallow-water samples from 12 fathoms, Levuka, Fiji; 12 and 24 fathoms, Nairai, Fiji; 18 fath- oms, Vavau Anchorage, Tonga Islands; off Niau and Niau Lagoon, Rongelap Atoll, Marshall Islands; 7 fathoms, Rotonga; Port Lotten, Kersail, Caroline Islands; and 21 fathoms, Guam Anchorage, Ladrone Islands. It did not occur at any of the deeper Albatross stations.

The species is larger, more tapering, and has fewer whorls than Buliminella parallela Cushman and Parker.

Res., vol. 18, p. 39, pl. 4, figs. 10a, b, 1937.

Variety differmg from the typical in its somewhat larger size and in the presence of a stout, basal spine. Length, 0.40-0.72 mm.; diameter, 0.24—0.38 mm.

The types are from the Oligocene, Grices Creek, Balcombe Bay, Kackeraboite Creek, and Altoona Bay Coal Shaft, Victoria, Australia. The variety also occurs in the Oligocene, Byram mar], Byram, Miss., and the Miocene and Recent of Australia, and in the Recent of the Fiji and Samoan Islands. In our material it has occurred at one Albatross station, H3931, Anu Anuraro Atoll, % mile southeast, in 405 fathoms at 42.5° F., co.s.pter.oz.mang.part., as a single specimen. A number of specimens were found in the material dredged at 40-50 fathoms off Fiji; a few at Mokaujar Anchorage, Fiji; and single speci- mens from Makemo Lagoon and Pinaki Atoll in the Paumotu Islands.

This variety has been given a new name owing to the priority of Egger’s Bulimina ovata d’Orbigny var. apiculata (1895).

There is a great variation in size. The Recent specimens are especially large and bear a close resemblance to Buliminella spinigera Cushman. They differ, however, in lacking the high polish of the latter, in having more numerous, more distinct chambers, and a less regular shape.

Test elongate, subcylindrical, broadly rounded at the initial end and increasing slightly in breadth toward the apertural end, circular or nearly so in transverse section; chambers and sutures indistinct owing to ornamentation of the surface, which consists of longitudinal costae usually somewhat spirally twisted, running unbroken from the initial to the apertural end and to the rim of the aperture; aperture rounded, circular or elliptical, in the middle of the sunken apertural face. Length, up to 0.75 mm.; diameter, 0.15-0.20 mm.

This is a widely distributed species in the Indo-Pacific with the exception of the records from the Tortugas region in the Atlantic, where it occurs rarely but in typical form. The aperture is often broken owing probably to the fact that the young are developed in the final chamber and the wall breaks down when they are released. Specimens have occurred at the following shallow-water stations: 12 fathoms, Levuka, Fiji; Mokaujar Anchorage, Fiji; 12 fathoms, Nairai, Fiji; Port Lotten, Kersail, Caroline Islands; and Rangiroa. In the Albatross material it occurred only at station H3954, west end of Nomuka Island, N. 33°, 6 miles east, in 600 fathoms, at 39.2° F., co.s.pum.pter.oz.

smooth, thin, translucent; aperture comparatively short, narrow, nearly in the line of the elongate axis, supplementary aperture very inconspicuous. Length, 0.50 mm.; diameter, 0.24 mm.

Brady’s types of this species were from Challenger station 120, off Pernambuco, Brazil. It has been recorded from the Indo-Pacific and Australian regions. We have a typical specimen from 98 fathoms, off the Big King, New Zealand, and one specimen from off the Philip- pines. It is interesting, therefore, to find that in our Pacific material this species is comparatively rare, occurring almost entirely at the deeper Albatross stations and found only once at Rutavu in the shallow-water samples and then only as a single specimen.

Test elongate, in the adult about 2% times as long as broad, periphery distinctly rounded, the early stages rapidly increasing in width as chambers are added, after which the sides become nearly parallel; chambers very distinct but not strongly inflated, of rather uniform shape throughout but increasing very slightly in size as added; sutures very distinct, limbate, peculiarly sigmoid, the mner end especially in the adult having almost a distinct angle after which the sutures pass to the border in a nearly straight line which is strongly oblique to the horizontal; wall smooth, but very distinctly perforate ; aperture at the base of the last-formed chamber, consisting of a broad loop-shaped opening. Length, 0.65 mm.; breadth, 0.30 mm.; thick- ness, 0.15 mm.

This species in its general size and shape is very similar to Bolivina eceanica, but the chambers are very different in their shape, and the sutures particularly with their sigmoid curvature and strongly limbate character are very distinct. The species is fairly common in the shoal water of various areas. It occurs about Fiji off Nairai in 12 and 24 fathoms; off Levuka, 12 fathoms; Viva Anchorage, 3 fathoms; Makemo Lagoon, Paumotu Islands; Rotonga, 7 fathoms; and at Guam Anchor- age, Ladrone Islands, 21 fathoms.

Test broad, muc: compressed, usually completely surrounded except at the aperture by a broad winglike flange, either entire or variously lobed; chambers inflated somewhat; sutures very distinct, slightly depressed; wall calcareous, with a few short, longitudinal costae, usually confined to the limits of the chamber on which they originate; aperture narrow, oval, with a single toothlike projection in the orifice. Length, up to nearly 1.00 mm.

This is a species originally described from the Indo-Pacific and confined to that area so far as authentic material has been examined. There are records for it from various Tertiary deposits, but the figures. accompanying the records do not seem to belong to this very definite species. In our Recent collections the species has occurred almost entirely at Albatross stations, as will be noted in table 6. There are two distinct forms, one very broad and with distinct transparent keels about the periphery especially of the later chamber, the other form somewhat narrower and with the keels eithtr wanting or greatly reduced. In both forms the characteristic costae are present but variable in number and strength. The only shallow-water station from which we had material is Viva Anchorage, Fiji, in 3 fathoms.

as high, the middle area of each expanded into coarse, spinose pro- jections; sutures distinct, strongly depressed, straight, oblique, form- ing an angle of 25°-30° with the horizontal in the adult, more strongly oblique in the early stages; wall distinctly perforate; aperture elongate, with a slightly expanded opening at the base of the inner margin of the chamber. Length, 0.60 mm.; breadth, 0.35 mm.; thickness 0.20 mm.

The types are from 40-50 fathoms off Fiji.

This resembles B. simpsoni Heron-Allen and Earland but is much more coarsely spinose.

This is a widely distributed species in comparatively deep water recorded at many stations in the Pacific but also apparently widely distributed in other parts of the world both Recent and fossil. It has not occurred abundantly at any of the stations, all of which are from the deeper-water Albatross collections. None of the highly developed forms with the long spine was present.

oblique, forming an angle of about 45° with the horizontal; wall distinctly perforate, ornamented by longitudinal costae, sharp and high, few in number, usually one prominent one toward the periphery at each side, with supplementary ones at the periphery; aperture broadly oval, sometimes with a slight lip. Length, 0. 50-0. 75 mm.; breadth, 0. 25-0. 35 mm.; thickness, 0. 20-0. 30 mm.

This species was originally described by Brady from off the Philip- pines, and there are very few records for the species, all of which are found in the same general region. It has occurred rather abundantly at only one station in our material, that from 3 fathoms, Viva Anchor- age, Fiji.

Test short and broad, slightly longer than broad, much compressed, periphery acute but not carinate, early portion with the axis much twisted; chambers few, distinct, comparatively high, periphery not lobulate; sutures distinct, not depressed; wall with numerous coarse punctae; aperture tending to become terminal, elongate, elliptical. Length, up to 0.35 mm.; breadth, up to 0.35 mm.

This species is one EF the characteristic ones of the Indo- Pacific region, although there are records for it in the Atlantic. Some of the colder-water records for this species are evidently not the same, as the name has been applied to various species of Bolivina that have the same twisted test. B. tortuosa as developed in the Indo-Pacific region and found rarely in the Tropics elsewhere is a very distinctive and easily distinguished form. In our Pacific collections it has occurred at numerous Albatross stations, as will be seen from table 8, and often in considerable numbers. Itis, however, most abundant in the shallow- water collections, occurring about the Fiji Islands in 40-50 fathoms; off Nairai, 12 fathoms; off Levuka, 12 fathoms; Viva Anchorage, 3 fathoms; and Mokaujar Anchorage. Inother collections it has occurred at Vavau Anchorage, Tonga Islands, 18 fathoms: Rangiroa; Makemo Lagoon, Paumotu Islands; inside the lagoon at Pinaki Atoll, Paumotu Islands; Rongelap Atoll, Marshall Islands; and Port Lotten, Kersail, Caroline Islands.

Test elongate, tapering, 2% to 3 times as long as broad, periphery rounded, initial end bluntly pointed, apertural end obliquely rounded; chambers numerous, somewhat inflated; sutures very slightly de- pressed, not very distinct; wall ornamented by a series of large coarse punctae somewhat irregularly arranged, those of the last- formed chambers finer and more numerous; aperture elongate, extend- ing from the base of the inner margin of the last-formed chamber to the highest point of the chamber. Length, up to 0.75 mm.; breadth, 0.25-0.30 mm.; thickness, 0.12-0.15 mm.

This is a widely distributed species in the Pacific material and is a striking one in its characters. The early portion of the test has a pearly luster and is very distinctive, the ornamentation consisting of coarse depressions with the portions of the wall between often raised into low platelike areas. Most of the records are from the deeper Albatross stations where it is often common, but it has also occurred somewhat less abundantly at the following shallow-water stations: Off Fiji, 40-50 fathoms; off Levuka, Fiji, 12 fathoms; off Nairai, Fiji, 12 and 24 fathoms; Viva Anchorage, 3 fathoms; and Mokaujar Anchorage, Fiji. It was abundant off Niau, and less abundant from Pinaki Atoll inside the lagoon. There are specimens also from Rangiroa; Vavau Anchorage, Tonga Islands, 18 fathoms; Guam Anchorage, Ladrone Islands, 21 fathoms; Rongelap Atoll, Marshall Islands; and from Makemo Lagoon, Paumotu Islands.

Bolivina oceanica CusHMAN, Contr. Cushman Lab. Foram. Res., vol. 9, p. 81, pl. 8, figs. 10a, b, 1933; Special Publ. No. 9, p. 147, pl. 19, fig. 31, 1937.

Test small, tapering only at the ends, greatest breadth rather rapidly attained after which the sides are nearly parallel for most of their length, periphery slightly rounded, test in end view elliptical; chambers fairly distinct, not greatly inflated, of rather uniform size and shape in the adult, increasing only slightly in size as added; sutures distinct, very slightly depressed, forming a very slight angle with the horizontal in the early stages and increasing slightly but gradually as chambers are added; wall smooth, distinctly perforate; aperture small, at the base of the inner margin of the last-formed chamber, forming a distinct re-entrant in the apertural face but not strongly contracted at the base. Length, 0.60 mm.; breadth, 0.25 mm.; thickness, 0.12 mm.

The types are from Albatross station H8838, lat. 16°57’00’’ S., long. 148°58’00’’ W., in 2,224 fathoms, vol. m. glob.

TROPICAL PACIFIC FORAMINIFERA OF “ALBATROSS” 25

This small species has occurred only in the Albatross material from the deeper-water stations, no specimens at all having been found in any of the shallow-water stations around any of the islands. It may be distinguished by its straight sutures, nearly parallel sides, and the increase in obliquity of the sutures from the early stages to the adult.

Test elongate, 2% to 3 times as long as broad, very much compressed; chambers becoming much broader as added, the inner margin high, thence tapering to the acute periphery, periphery slightly rounded or even slightly carinate; sutures distinct, limbate, very little if at all depressed, very strongly oblique backward or slightly sigmoid especially in the later chambers; wall smooth, very finely perforate; aperture large, elongate, taking up nearly the whole of the inner margin of the last-formed chamber. Length, up to 1.00 mm.; breadth, 0.35—-0.40 mm.; thickness, 0.10—0.12 mm.

The records for this species are few. It was originally described by Brady from Challenger material from East Moncoeur Island, Bass Strait, 38 fathoms, and from off Raine Island, Torres Strait, 155 fathoms. It was recorded as rare at both localities. Jensen’s record

26 BULLETIN 161, UNITED STATES NATIONAL MUSEUM

for the species is from foraminiferal sand dredged 16 miles east of Wollongong off Australia, at a depth of 100 fathoms. In our present collections the species has occurred as single specimens at two Alba- tross stations as follows: H3989, South Pass, Likieb, 4% mile north, 468 fathoms, 42.6° F., crs. co. s. (U.S.N.M.

Test elongate, subcylindrical, very slightly compressed, initial end rounded; chambers numerous, high, very slightly inflated; sutures distinct but not depressed; wall hyaline, the lower half of each chamber with rather coarse foramina, the upper half clear; aperture elongate, loop-shaped; transparent except the lower half of each chamber, which is whitish. Length, up to 1.00 mm.

The original references for this are from the cold waters of the North Pacific as are also the other records. It occurs also in the late Tertiary of California. Specimens apparently identical with this species occur in our present material only at three Albatross stations in the eastern part of the area.

Test elongate, subcylindrical, the apex bluntly pointed; chambers numerous, inflated, the sutures fairly deep, the surface smooth except the portion at and just above the sutures, which is minutely spinose or granular; aperture large, loop-shaped, with a slightly raised border. Length, 0.50-0.75 mm.; breadth, 0.15 mm.; thickness, 0.12 mm.

This species occurs at numerous Albatross stations, data for which are given in table 12.

BOLIVINA CAPITATA Cushman PuaTE 8, Figures 1-3

Bolivina capitata CusHMan, Contr. Cushman Lab. Foram. Res., vol. 9, p. 80, pl. 8, figs. 12a, b, 1933; Cushman Lab. Foram. Res. Special Publ. No. 9, p. 146, pl. 19, fig. 29, 1937.

Test elongate, about 3 times as long as broad, tapering gradually from the subacute initial end to the somewhat swollen apertural end, periphery rounded and somewhat lobulated; chambers numerous, distinctly inflated, especially toward the apertural end; sutures dis- tinct, depressed, strongly oblique; wall smooth, nearly transparent, finely perforate; aperture broadly elliptical, sometimes tending to become terminal. Length, up to 0.50 mm.; breadth, 0.15 mm.; thickness, 0.10 mm.

It has occurred rather commonly at the shallow water stations: 12 and 24 fathoms off Nairai, Fiji, and 12 fathoms off Levuka, Fiji. Specimens were also obtained from 7 fathoms off Rotonga.

BOLIVINA GLOBULOSA Cushman PLATE 8, Figure 4

Bolivina globulosa CusHMAN, Contr. Cushman Lab. Foram. Res., vol. 9, p. 80, pl. 8, figs. 9a, b, 19383; Cushman Lab. Foram. Res. Special Publ. No. 9, p. 146, pl. 19, fig. 30, 1937.

Test small, elongate, tapering gradually from the subacute initial end to the greatest breadth formed by the last two chambers, periphery rounded; chambers inflated, more or less globose, increasing rather uniformly in size as added; sutures distinct, depressed, somewhat sigmoid, slanting backward but a small amount from the horizontal; wall smooth, finely perforate; aperture comparatively large, at the base of the last-formed chamber and forming a loop-shaped opening. Length of holotype, 0.70 mm.; breadth, 0.40 mm.; thickness, 0.15 mm.

The type is from Albatross station H3786, lat. 12°07’00’’ N., long. 137°18’00’’ W., in 2,883 fathoms, It. br. rad. oz.

This is a small species but is rather widely distributed in the Alba- tross collections. It has usually not occurred in any considerable numbers at any particular station. The data for these are given in table 13. No specimens were found at any of the shallow-water stations about the various islands.

Test much compressed, nearly as broad as long, widest just above the middle; chambers comparatively few, fairly distinct; sutures strongly curved, the inner portion of each chamber showing signs of a subdivision in some cases; wall smooth; aperture at one side, rounded, with a very slight lip. Length, about 0.25 mm.

This seems to be a very rare species described by Brady from 255 fathoms off Kandavu, Fiji, and I have recorded it from stations off Samoa. I have single typical specimens, one from Albatross station H3945, northeast point of Murea Island, 5 miles southwest, in 981 fathoms, at 36.7° F., ers. vol. s. pter., the other from Mokaujar An- chorage, Fiji. This seems to be a very distinct but very rare form so far as the records show, being confined to the area of the Fiji and Samoan Islands.

end subacute, apertural end broadly rounded, periphery acute but not keeled, the early chambers often with short backward-pointing spines; chambers distinct, about as high as broad but much over- lapping so that the visible portion of the chamber in the early stages is apparently 2 or 3 times as broad as high; sutures distinct, but only slightly depressed, only slightly oblique; wall nearly transparent except toward the base of the chamber where it becomes opaque due to the large close-set perforations; aperture elongate, comma-shaped. Length, 0.25 mm.; thickness, 0.10 mm.

The types are from Albatross station H3989, South Pass, Likieb, ¥ mile north, in 468 fathoms, at 42.6° F., crs. co. s.

This is a very distinctive species, occurring in small numbers but at numerous Albatross stations, as will be seen in table 14. Its dis- tribution is comparatively limited as the position of these stations shows them all to be in the general region of the Marshall Islands. The only shallow-water station at which the species occurred is that of Rongelap Atoll, Marshall Islands.

toward the apertural end, where height and breadth are often about equal; sutures distinct, slightly limbate, obliquely curved, forming an angle of about 30°-40° with the horizontal, slightly depressed in the adult portion; wall finely perforate, smooth, except for the early portion, which has numerous, fine, longitudinal costae, sometimes running up halfway of the length of the test; aperture elongate, par- row at the base, and somewhat expanded at the upper end. Length, 0.35 mm.; breadth, 0.10 mm.; thickness, 0.03-0.04 mm.

This species has previously been known only from the Atlantic, but typical specimens occur commonly at Vavau Anchorage, Tonga Island; in Niau Lagoon and off Niau; 12 fathoms off Nairai, Fiji; and slightly less common inside the lagoon at Pinaki Atoll. There is a single record for it in the Albatross material at station H3915, Pinaki Atoll, 3.5 miles southeast, in 860 fathoms, 37.0° F., glob. mang.

Test elongate, usually compressed, early portion often slightly twisted; early chambers biserial with the aperture as in Bolivina at the base of the apertural face, but in the adult tending to become uniserial and the aperture failing to reach the base of the chamber, finally becoming terminal. Cretaceous to Recent.

This genus represents a further development from Bolivna, in which the aperture becomes terminal at the same time that the chambers become uniserial, a combination of the chambers seen in a great many other groups of Foraminifera.

There are a number of well-characterized species in the Pacific material, some of which also exist in the West Indian region of the Atlantic.

Test elongate, 3 or 4 times as long as broad, much compressed, taper- ing at the ends, the middle portion with the sides nearly parallel, thickest along the median line thence thinning toward the lateral margins which are subacute, the whole test usually somewhat twisted; chambers rapidly increasing in height as added until in the adult they are as high as wide, slightly inflated; sutures very distinct, strongly limbate, rather strongly curved backward; wall calcareous, smooth, coarsely perforate; aperture elongate, oval, in the adult becoming terminal. Length, up to about 1.00 mm.; breadth, 0.35- 0.40 mm.; thickness, 0.20-0.25 mm.

This species is a common one in the Indo-Pacific region and also occurs in typical form but much more rarely in the West Indian region. Many records for this species, especially those without figures, make it difficult to determine whether they are typical or belong to some of the varieties. In our material the typical form of the species has been rare, occurring only at Levuka, Fiji, in 12 fathoms, and from two Albatross stations: H3830, lat. 15°00’30”’ S., long. 148°47'00’’ W., in 1,257 fathoms, wh. co. s. glob. vol. part., and H3984, entrance to South Pass, Rongelap, 1% miles north in 746 fathoms, 39° F., ers. co. s.

Variety differing from the typical form of the species mainly in the addition of longitudinal costae usually few in number and mostly near the base of the test. Length, up to 2.00 mm.; breadth, 0.40 mm.; thickness, 0.20 mm.

This variety is much commoner than the typical form wherever the species occurs and often has a larger test and is usually strongly twisted. In our Pacific material this variety has occurred most abundantly at Guam Anchorage, Ladrone Islands, in 21 fathoms, but specimens also occur at Nairai, Fiji, 24 fathoms; Vavau Anchorage, Tonga Islands, 18 fathoms; Rotonga, 7 fathoms; Rangiroa; and also at the Albatross stations in deeper water given in table 17.

Test elongate, somewhat compressed, periphery lobed, early portion tapering, remainder of the test with the breadth rather uniform; chambers distinct, the early ones rather uniformly increasing in size as added, later ones becoming more inflated and more distinctly separated ; sutures distinct, depressed, strongly oblique, nearly straight; wall ornamented by a distinct raised ridge somewhat above the suture, the periphery of which is often toothed and the later chambers some- what roughened; aperture elongate, terminal in the adult, with a slight lip. Length, 0.75 mm.; breadth, 0.40 mm.; thickness, 0.25 mm.

Most of the records for this species are from the Indo-Pacific region. The types were from off New Guinea. There are a number of other records from this same general region some of which have no figures accompanying them. There are also other records for the species from other areas both fossil and Recent, but the figures accompanying these records show rather distinctly that they are not the same as this Indo-Pacific species of Brady. The only specimen of this species that we have from this area is from the Paumotu Islands, Albatross station H3870, village, point of Anaa Atoll, S. 50°, 5 miles west, in 1,110 fathoms, 36.0° F., fne.co.s.pter.oz.glob.

Lozxostoma vertebrale CUSHMAN (in part), ibid., p. 194.

Test very elongate, slender, about 4 times as long as broad, periph- ery serrate in front view, rounded in end view; chambers distinct, inflated, as high as broad throughout, early ones smooth except for a spine at the peripheral angle, later ones very deeply excavated on the lower side and crenulate at the border, tending to become somewhat uniserial in the adult; sutures distinct, depressed, very strongly so in the adult, oblique; wall of early portion smooth, later portion smooth except for the crenulate border; aperture elongate, oval, with a dis- tinct lip, tending to become terminal.

This species is close to L. vertebrale (Cushman), and the two may be easily confused. JL. convallarium occurs in our shallow water collec- tions from off Fiji, 40-50 fathoms; off Nairai, 12 fathoms; off Levuka, 12 fathoms; and Rotonga, 7 fathoms.

Test very elongate, slender, 5 to 6 times as long as broad, tapering from the subacute initial end, but very gradually, much twisted, in some adult specimens making a complete turn, periphery lobulate; chambers numerous, distinct, somewhat inflated, in the adult higher than broad, basal margin in the adult typically projecting above the previous chamber; sutures distinct, somewhat limbate in the early portion, deeply depressed in the adult; wall in the early stages with indistinct, longitudinal costae, in the later chambers smooth, except near the lower margin, which has numerous, very short, fine spines; aperture in the adult tending to become terminal, elongate, curved, with a slight lip. Length, up to 0.75 mm.; breadth, 0.15 mm.

A few specimens occurred in our material from Vavau Anchorage, Tonga Islands, 18 fathoms; from Rotonga, 7 fathoms; and from off Nairai, 12 fathoms. The species is easily confused with L. convallarvum (Millett).

Variety differing from the typical in the much greater depression of the whole test, the periphery acute and carinate, aperture elongate.

The only station at which this variety was represented is Albatross H3896, Tekokoto Atoll, 1 mile east, Paumotu Islands, 617 fathoms.

distinct, limbate, slightly depressed, more so in the later portion, in the early portion oblique and nearly straight, later becoming sigmoid as the chambers tend to become uniserial; wall coarsely perforate, the perforations often in longitudinal lines and the surface with a few short, weakly developed costae; aperture in the adult terminal, nar- rowly elliptical, often with a slight, rounded lip. Length, up to 2.00 mm.; breadth, 0.30 mm.; thickness, 0.20 mm.

The figured specimens are from off Nairai, Fiji, in 24 fathoms, where the species is very common and well developed. It also occurs off Levuka, Fiji, 12 fathoms; Viva Anchorage, Fiji, 3 fathoms; Mokaujar Anchorage, Fiji; Vavau Anchorage, Tonga Islands, 18 fathoms; Guam Anchorage, Ladrone Islands, 21 fathoms; Port Lotten, Kersail, Caroline Islands, and at one Albatross station, H3840, lat. 17°21’00’’ S., long. 149°15’00’’ W., in 1,585 fathoms, vol. m. Judged from the fact that this is typically a shallow-water species probably these specimens in the Albatross collections represent individuals carried by the cur- rents and deposited in deeper water, a frequent occurrence about ocean- ic islands.

apertural end; sutures fairly distinct, very slightly depressed toward the apertural end, becoming gradually more oblique as chambers are added; wall smooth, very finely perforate; aperture in the adult terminal, ovate, without a distinct lip. Length, 0.75 mm.; breadth, 0.25 mm.; thickness, 0.15 mm.

The types of this species are from Albatross station H3840, lat. 17°21’00”’ S., long. 149°15’00’’ W., in 1,585 fathoms, vol. m.

While it has not occurred in any considerable numbers, nevertheless it has been found from a number of different stations at which the characters of the species are held rather uniformly. From the records it seems to be a species of comparatively deep water and did not occur in any of the material from the shallow water about the various islands.

Test pyramidal, 3-sided, triangular in transverse section, angles of the test usually acute, the sides flat ur slightly concave, initial end acutely pointed, initial end and angles of chambers often with sharp spines more or less strongly developed; sutures distinct, often limbate, usually not raised but occasionally strongly so; wall of medium thickness, calcareous, hyaline, usually distinctly perforate, in some cases thickened and the surface roughened, occasionally with definite beadlike ornamentation near the periphery of the chamber; apertural end of test bluntly angled, the edges of the cham- bers thickened, the aperture itself a curved slit at the base of the inner margin of the chamber. Length, up to 1 mm.; breadth, 0.50-0.70 mm.

This species is a very variable one especially in the amount of spines ornamenting the test. It is a widely distributed species, occur- ring at least as far back as the Miocene and being widely distributed at the present time particularly in rather shallow water. In the Pacific material it has occurred at numerous Albatross stations, data for which are given in table 19. In the shallow water material it has occurred about Fiji near Nairai, 12 and 24 fathoms; off Levuka, Fiji, 12 fathoms; Viva Anchorage, Fiji, 3 fathoms; Mokaujar Anchor- age, Fiji; and at the deeper station 40-50 fathoms off Fiji. It has

also occurred at Vavau Anchorage, Tonga Islands, 18 fathoms; Pinaki Island, Paumotu Islands; Makemo Lagoon, Paumotu Islands; off Rotonga, 7 fathoms; Rongelap Atoll, Marshall Islands; off Ran- giroa, 21 fathoms; Guam Anchorage, Ladrone Islands; and at Port

Lotten, Kersail, Caroline Islands.

Genus TRIMOSINA Cushman, 1927

Trimosina CusHMAN, Contr. Cushman Lab. Foram. Res., vol. 3, p. 64, 1927.

Genoholotype.—Mimosina spinulosa Millett, var.

Test triserial; chambers with a single acicular spine, or these may become obsolete; wall calcareous, vesicular; aperture elongate, removed from the edge, sometimes with an added series of rounded pores along the base of the apertural face. Recent.

TRIMOSINA ORIENTALIS Cushman Puate 12, Figures 1-5 Trimosina orientalis CusHMAN, Contr. Cushman Lab. Foram. Res., vol. 9, p. 78, pl. 8, fig. 4, 1933.

Test elongate, tapering, 2 or 3 times as long as broad, the basal ends of the chambers much angled especially in the young stages; chambers very distinct, inflated, the early ones very angular, those of the adult becoming less so; sutures distinct, depressed; wall coarsely perforate; aperture an elongate, curved, slitlike opening becoming

broader in the last-formed chamber. Length, up to 0.55 mm.; diam- eter, 0.25 mm.

The types are from 7 fathoms off Rotonga.

This is apparently a species of shallow warm water and has a wide distribution as the following records of our material show: In the vicinity of the Fiji Islands, 12 and 24 fathoms off Nairai; 12 fathoms off Levuka; 3 fathoms, Viva Anchorage; and 40-50 fathoms off Fiji; as well as at Mokaujar Anchorage. Specimens also were found com- mon at Vavau Anchorage, Tonga Islands, in 18 fathoms, and rare specimens occurred in the material from Rongelap Atoll, Marshall Islands.

TRIMOSINA PERFORATA Cushman PLATE 12, FiaurRE 6

Trimosina perforata CusHMAN, Journ. Washington Acad. Sci., vol. 19, p. 157, figs. la, b (in text), 1929.

Test small, generally triangular in both side and end views, angles acute; chambers triserial throughout, rapidly increasing in size as added, the angles of the chambers usually protruding and early cham- bers sometimes twisted; sutures distinct, not depressed, slightly lim- bate; wall calcareous, finely perforate with coarser perforations along the borders near the sutures connecting with the interior by definite tubules, generally smooth, thin and nearly transparent; apertural face convex, with numerous ridges and irregular projections, aperture consisting of a long narrow opening connecting with the basal mar- gin by a narrow slit at a sharp angle to the axis of the main opening, bordered by a distinct thickened lip, the apertural face with numerous irregularly rounded openings. Length, 0.50 mm.; breadth, 0.35 mm.

This species, which was described from 40-50 fathoms off Fiji, seems to be a very limited one in its distribution; it has not been recorded elsewhere, although it is fairly common at the type locality.

TRIMOSINA SIMPLEX Cushman PLATE 12, FIGURE 7

Trimosina simplex CusSHMAN, Journ. Washington Acad. Sci., vol. 19, p. 158, figs. 2a, b (in text), 1929.

Test of medium size, triangular in both side and end views, angles acute; chambers triserial throughout, uniformly increasing in size as added, angles of the chambers slightly spinose, the outer angle thick- ened, almost carinate; sutures distinct, not depressed, very slightly limbate, rather evenly curved; wall calcareous, coarsely perforate, especially along the borders, smooth, fairly thick but translucent; apertural face slightly convex, fairly smooth, the aperture elongate without a lip, and with a few supplementary openings in the center of the terminal face. Length, up to 1.00 mm.; breadth 0.50 mm.

TROPICAL PACIFIC FORAMINIFERA OF “ALBATROSS” 45

This species, like perforata, was described from rich collections taken at a depth of 40-50 fathoms off Fiji and has not been obtained in any of the other material. It is larger than perforata, and the outline of the chambers in the early portion is very distinct in the two species.

Mimosina pacifica CusHMAN, Contr. Cushman Lab. Foram. Res., vol. 9, p. 77, pl. 8, figs. 3a, b, 1933.

Test irregularly triserial except in the adult portion, which becomes biserial, tapering from an acute initial end to the broad rounded aper- tural end, nearly circular in end view; chambers distinct, inflated; sutures of the early portion indistinet, later ones slightly depressed; wall calcareous, finely perforate, the initial portion with short spines which in the later portion become largely confined to the base of the chamber; aperture double in the adult, a narrow slit at the base of the inner margin of the last-formed chamber above, which is a low, elong- ate, supplementary opening. Length of holotype, 0.35 mm.; diameter, 0.25 mm.

The types are from off Levuka, Fiji, 12 fathoms.

This distinctive small species also occurs at Mokaujar Anchorage, Fiji, and Rongelap Atoll, Marshall Islands.

Genus CHRYSALIDINELLA Schubert, 1907

Chrysalidinella ScuusERT, Neues Jahrb. fiir Min., vol. 25, p. 242, 1907. Chrysalidina of authors (not d’Orbigny).

Genoholotype.—Chrysalidina dimorpha H. B. Brady.

Test tapering, triangular in transverse section, early chambers tri- serial, later ones becoming uniserial; wall calcareous, perforate; aperture in the adult cribrate, consisting of numerous rounded open- ings scattered over the triangular apertural face. Miocene to Recent.

This genus is directly derived from Reussella. The stages in de- velopment are very nicely seen in material from the station at 40-50 fathoms off Fiji, and show that it has a very close connection with Reussella at this station. As already noted it cannot have been derived from Chrysalidina, as is held by some authors, as that very large coarsely arenaceous genus belongs in the family Verneuilinidae.

Test elongate, tapering, triangular in transverse section, the sides nearly equal, flat, or somewhat carinate, angles acute, early portion consisting of chambers arranged triserially, the later portion with chambers in a single series; sutures distinct, slightly limbate, curved, not raised; wall smooth but distinctly and somewhat coarsely perfo- rate; aperture in the early stages similar to that in Reussella, in the adult numerous, scattered more or less irregularly over the terminal face of the chamber. Length, up to 0.50 mm.; breadth, 0.25-0.35 mm.

This is a widely distributed species in the Indo-Pacific, but it has

not occurred widely in our material. The best specimens are from

40-50 fathoms off Fiji.

Test elongate, somewhat fusiform, or the basal portion somewhat inflated and later chambers becoming nearly uniserial; chambers inflated, later ones particularly rather distinct, early ones sometimes obscured by the ornamentation of the surface; sutures slightly de- pressed, fairly distinct; wall ornamented by numerous, fine, short, rather evenly distributed spines, covering the entire surface, often even on the neck itself; aperture elongate, cylindrical, in well-preserved specimens with an everted lip, apertural opening being rounded. Length, up to 1 mm.; breadth, 0.20-0.35 mm.

This has proved to be a rather common species in our Tropical Pacific material, but it is a species of comparatively deep water and has not occurred at the shallower water stations about the various slands. Its distribution with data is given in table 20.

Test much elongated, the early chambers in a close spiral, later ones drawn out and considerably separated from one another, in an irregular loose spiral, the later chambers particularly being somewhat concave below, the peripheral angle angular and projecting, upper surface convex and ornamented by coarse longitudinal costae which project slightly at the periphery making it serrate; sutures distinct, depressed; wall calcareous, usually opaque, ornamented as already noted; aperture with an elongate tubular neck, but the lip usually only slightly developed. Length, up to 0.65 mm.; breadth, 0.20 mm.

The records for this species are almost entirely from the Pacific. The other records referred to this are probably not the same. Our specimens are mostly from off Levuka, Fiji, in 12 fathoms, where it is common. It also occurs in shallow water near Nairai, Fiji, but the few other records are from Albatross stations, data for which are given in table 21. These, strangely enough, are all from the western part of the area in which the Albatross dredged. The following variety is very distinct.

Variety differing from the typical in the very elongate test, in the much greater separation of the chambers into a loose spiral, and in the high development of the peripheral keel, the lower side of the cham- bers becoming distinctly concave.

This variety is common at the station from 40-50 fathoms off Fiji but was not met with elsewhere. Sidebottom’s types were from off the east coast of Australia in 465 fathoms. Bermudez has recorded it from off the north coast of Cuba.

This species described by Schwager from the Pliocene of Kar Nicobar is a fairly common one in various parts of the Pacific. In our present material it is not nearly so abundant as is the preceding species. It may be distinguished from U. ampullacea by the stouter form of the test, which does not have the chambers so definitely concentrated at the base, in the adult stage tending rather to become biserial than uniserial. In our material it is represented particularly by the following variety.

This genus is well developed in the Pacific and shows three of the principal developments of ornamentation in the group, longitudinally costate, finely spinose, and strongly pitted. Some of the specimens are very similar to Rectobolivina and perhaps should be placed in that genus, which is one closely allied to Siphogenerina but derived evi- dently from Bolivina. There is a great difference in the microspheric and megalospheric forms in the shape of the test, which in the micro- spheric has a sharply tapering base, while the megalospheric form is broadly rounded at the base.

Test elongate, somewhat tapering, composed of a number of in- flated chambers, the early ones in a uvigerine arrangement, later ones uniserial, the uniserial portion making up most of the test, surface hispid; aperture large, terminal, with a broad everted lip, the border of which often has a series of backwardly pointing, long, acicular spines. Length, up to 1.75 mm.; diameter, 0.30 mm.

There is a tendency in many of the specimens to reduce greatly the early stages so that in the megalospheric form nearly the entire test is uniserial. This typically Indo-Pacific species has occurred at a number of stations in our Pacific material, but all from the shoal-

water material where it is often very abundant. It is abundant at some of the stations off Fiji, in 12 fathoms off Nairai; 12 fathoms off Levuka; Mokaujar Anchorage, Fiji; and Viva Anchorage, Fiji. It occurs less commonly at Vavau Anchorage, Tonga Islands, 18 fathoms; Rotonga, 7 fathoms; and Port Lotten, Kersail, Caroline Islands.

Variety differing from the typical in the greater number of uniserial chambers, the cylindrical form of the test, and the much more promi- nent depressions at the base of the chambers along the sutures.

This variety is widely distributed in the Pacific in Recent samples, and it is also recorded by Schubert from the Globigerina marl of late Tertiary age from Panaras in the Bismarck Archipelago, and by Koch from the late Tertiary of Kabu, Java. Most of the records are from offshore stations, and the same holds true in the Albatross material under discussion. ‘The species has not occurred at any of the shoal- water stations, all of them being from the Albatross dredgings, data for which are given in table 24.

Test elongate, subcylindrical, somewhat tapering, straight or very slightly curved; chambers comparatively few, those of the uniserial portion well rounded, shorter than broad; sutures only slightly con- stricted; aperture large, terminal, with a very short tubular neck and broad flaring lip; wall smooth. Length, up to 2.25 mm.; diameter, 0.50 mm.

This is the least common of the species of the genus in our material. It has occurred in only one of the shoal-water stations, in 24 fathoms off Nairai, Fiji, and rarely at three of the Albatross stations, data for which are given in table 25. The figured specimen is a megalospheric one in which the proloculum is very large, but the general characters. of the test are typical.

Genus ANGULOGERINA Cushman, 1927

Angulogerina CusHMAN, Contr. Cushman Lab. Foram. Res., vol. 3, p. 69, 1927. Uvigerina (part) of authors.

Genoholotype.— Uvigerina angulosa Williamson.

Test triserial, elongate, the whole test angled, with three flattened sides and distinct angles; wall calcareous, perforate; aperture at the end of a short neck, with a phialine lip. Eocene to Recent.

Instead of the distribution of this genus being in temperate shallow waters, as has been recorded by some authors, there are a number of characteristic species found in shallow tropical waters of the Atlantic, but in the Pacific it occurs at very considerable depths, where it is often abundant, as off the California coast. Specimens are rare in the Pacific material that we have, and only two species are represented.

This variety is already known from fairly deep water in the eastern Pacific. The last chamber is usually smooth, but the early ones show longitudinal costae and the chambers are decidedly angular. Our specimens are all from the Albatross dredgings, data for which are given in table 27.

Test minute, elongate, triangular in transverse section, the periphery somewhat lobulate; chambers distinct, those of the last-formed por- tion becoming more distinct and remote; sutures distinct and depressed ; wall ornamented with longitudinal costae on all but the last-formed chambers in the adult; apertural end drawn out into a short tubular neck and slight phialine lip. Length, 0.30 mm.; diameter, 0.12 mm.

The figured specimen does not show the uniserial stage very highly developed. This species, originally described from the Atlantic in the West Indian region, is found rarely also in the Pacific about the oceanic islands. We have records for three Albatross stations, given in table 28. The species is also known from the Miocene onward, botb in Florida and California.

Test elongate, slightly tapering toward either end, often somewhat twisted, triangular in transverse section, with carinae at three angles, thin and fairly high, running from the initial end to the aperture, even onto the neck itself; chambers distinct, those of the earlier portion at least irregularly spiral, later ones less distinctly so; sutures distinct but not depressed; wall thin, translucent, finely punctate, smooth; aperture terminal, central, at the end of a short tubular neck, usually with a phialine lip. Length, 0.40 mm.; breadth, 0.18 mm.

This species is widely distributed both in the Atlantic and Pacific. It is possible that the Pacific form may be distinguished from the Atlantic one, the latter having the sides more concave and the carinae at the angles higher and more prominent with a thinner keel while it is less distinctly perforate. This is not the same as d’Orbigny’s Vaginu- lina tricarinata, which is a peculiar form with the aperture at one angle. This species occurs most abundantly in deep water, as will be seen by the data of the long list of Albatross stations given in table 29. Besides these, specimens have occurred in 12 fathoms off Nairai, Fiji; 12 fathoms off Levuka, Fiji; and in 7 fathoms off Rotonga.
