A REPORT ON SOME ARENACEOUS FORAMINIFERA (Piates 1-12) By JOSEPH A. CUSHMAN and IRENE McCULLOCH THE UNIVERSITY OF SOUTHERN CALIFORNIA PUBLICATIONS ALLAN Hancock PAciric EXPEDITIONS VoLuME 6, NUMBER 1 IssueD Aucust 14, 1939 THE UNIVERSITY OF SOUTHERN CALIFORNIA PRESS Los ANGELES, CALIFORNIA A REPORT ON SOME ARENACEOUS FORAMINIFERA (Piates 1-12) Jos—EpH A. CUSHMAN and IRENE McCuLiocH From relatively shallow waters along the eastern edge of the Pacific from Seward, Alaska, to areas off the coast of Peru, large numbers of bottom samples have been assembled for study. That such a collection for study exists is due almost entirely to the interest, energy, and efficiency of Captain Hancock personally. In this connection due credit must be given to a mechanical genius, Alex Campbell, Chief Engineer of the Velero III, for devising all sorts of mud dippers when needed, ranging from a section of pipe to most efficient metal snappers. The sincere appreciation herein expressed means so much more when it is remembered that the several specialists on each expedition always became too engrossed in special fields to devote time and energy to collecting material outside their special interests. From time to time additional material has been added to the collec- tions brought back by the Velero III, by people who were visiting re- mote areas and knew the value of comparative material in connection with such extensive studies. Such aid has been invaluable and the hope is expressed that even greater amounts of such material will be avail- able in the future for comparative studies. Unfortunately, when the system of numbering samples was begun there was no way of anticipating the scope of the work in the future. In 1932 the plan of arbitrarily using the figure “1” for all samples off San Pedro; the figure “2” to begin the number of all samples off Mexico; “3” for South America; ‘4’ for Galapagos; ‘5’ for South America was adopted. Shortly afterward, a trip to Alaska resulted in a series beginning with “A”; “V” for British Columbia; “W” for Washington; “C” for one collection of samples from off the coast of northern California to Los Angeles. Beginning northward and proceeding southward the station lists arranged in tables record the available data. The arenaceous foraminifera recorded in the following pages do not represent all the species obtained in the dredgings. As in all similar collections there are single specimens, or incomplete ones, or specimens representing the early stages alone. While it may be evident that these . bay 999 2 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 probably belong to described species not present in adult form, or pos- sibly to undescribed ones, it is much better to wait until additional material shall be available before assigning such material to definite names. In these arenaceous forms which, in part at least, use the materials from the bottom on which they live to form the test, there must be a considerable variation as bottom materials change. In some of the species we have attempted to illustrate examples of this varied test material. Being the most primitive group of the foraminifera it is not surprising that there is considerable variation in different characters, although it is perhaps most noteworthy that the characters of a species are so definitely held. It is interesting to find that many of the species found along the Eastern Pacific in cold waters are similar to or identical with those described from the Arctic and Antarctic regions. Others are known as yet only from the Eastern Pacific but it is to be expected that their range will be extended by later explorations. Collections upon which this report is based are a part of the collec- tions of the Allan Hancock Foundation, The University of Southern California, Los Angeles. The official abbreviation is AHF used in the numbering of all specimens, including the holotypes and paratypes. Paratypes of the new species will be deposited at Smithsonian Insti- tution, Washington, D.C., and at Cushman Laboratory for Foraminif- eral Research, Sharon, Mass.

Test free, consisting of a single elongate oval or pyriform chamber with a more or less distinct tubular neck usually tapering gradually from the body of the chamber, undivided; wall fairly thick, of sand grains of variable size, firmly cemented or in small specimens with an excess of cement and fairly smooth; aperture circular, simple, terminal. This is a common and well-distributed species in our collections occurring at the following stations: 213, 253, 14, 414, 298, 538, 253, 512, 573, 583, 1021, 511, 2014, 325, 2066, 1024, 1034, 2026, 2029, 61, 2063, 506, 106, 2050, 516, 517, 508, 509. There is a considerable amount of variation particularly in the material of the test, evidently somewhat dependent upon the character of the bottom on which it lives and the kind of building material available. The figured specimen is one which has used comparatively few sand grains but is mostly com- posed of other foraminiferal tests. Distribution —Numerous stations from near San Francisco, Cali- fornia, southward to stations off South America. Proteonina difflugiformis (H. B.

Test elongate, subcylindrical, often somewhat tapering toward the apertural end, straight or nearly so, composed of a rather large globular proloculum and elongate cylindrical or slightly tapering second cham- ber slightly less in diameter than the proloculum; wall thick, loosely cemented especially on the exterior, rough, composed usually of fine sand, sometimes mixed with coarse sand particles, occasionally with a varying amount of sponge spicules, interior commonly smoother, with a yellowish-brown cement; aperture circular, at the distal end of the second chamber. Diameter, 2.00 mm; length, up to 10.00 mm. There is a considerable amount of variation in the material of which the test is made, undoubtedly depending much on the character of the bottom. Some of our specimens have a considerable proportion of sponge spicules included at certain stations and this is shown in our figured specimens. Localities: 415, 487, 447, 2026.

This species was originally described from off the Falkland Islands. Very elongate specimens nearly 10.00 mm in length occurred at several stations. They are made up entirely of sponge spicules and apparently closed at one end as in the type figures. It is difficult to distinguish be- tween the broken portions of this species and those of Marsipella. There is a possibility that Marsipella elongata may have been described from the tubular portions of this species. Stations: 414, 299(?), 450, 451, 465(?). Distribution.—Gulf of California, San Jose de Cubo, 82 fms. ; Gala- pagos Islands, north and south of Duncan Island, south of Albemarle Island ; Post Office Bay and Black Beach, Charles Island, in depths rang- ing from 15 to 68 fms.

No. 1 CUSHMAN, MCCULLOCH: ARENACEOUS FORAMINIFERA 53 Our figured specimens show a peculiar species made up of broken sponge spicules and arranged in sections, the lines of growth appearing almost as sutures but not showing any sign of division in the interior. Lacroix has described a species from the Mediterranean which is so similar in its characters that it seems, in spite of the long distance be- tween the localities, that the two may be identical. Our specimens occurred at stations 414, 415, and 417. Distribution.—Galapagos Islands, several stations near Duncan Is- land, in 55 to 68 fms.

Test free, consisting of an ovoid proloculum passing into a short, tubular chamber, soon becoming branched, of nearly uniform diameter throughout; wall composed of sand grains, firmly cemented with numer- ous sponge spicules fixed in the outer layer, giving a bristling appear- ance to the whole test; apertures formed by the open ends of the tubu- lar chamber; color reddish or yellowish brown or gray. Rare specimens show the proloculum. There is a considerable range in the material of which the test is made. At one station, 2070, there is a series of very small, slender specimens that are assigned here but they are very minute compared with the usual run of material. Locali- ties: 2034, 2035, 2024, 2063, 299, 246, 290, 226.

Test short and thick, composed typically of three chambers, increas- ing rapidly in size as added, last-formed chamber making up a large proportion of the test, fusiform or elliptic, axis of the test straight or more often slightly curved; wall composed of angular quartz sand grains with a considerable amount of gray cement between; apertural end slightly tapering, without a definite neck, the aperture being an opening between three or more sand grains at the end of the chamber. Our material shows a very great variation in the type of material of which the test is built but the general form remains fairly constant. Specimens from sandy bottoms such as that figured very closely resem- ble the type specimens. Others in different conditions use in addition fragments of mollusca and occasionally other foraminifera.

Distribution These studies record this species as far north as the South Farallone Island, San Francisco, California, in 38 fms.; as far south as Gorgona Island, Colombia, in 32 fms. A single record for the Galapagos Islands is Cartago Bay, Albemarle Island, in 12 fms. Numerous localities off southern California and Mexico have this species. In the Gulf of California it has been recorded as far north as San Pedro Nolasco Island, in 32 fms. Reophax scorpiurus Montfort (?) Plate 2, Fig. 13 Under this species have been placed very many elongate and irregu- lar forms of Reophax. Brady’s figures in the Challenger Report assigned to this species cover a wide range of form and building materials in the tests. There are numerous specimens in our collections ranging from the very coarse test figures (Pl. 2, Fig. 13) to those of pure sand grains. It is difficult to tell how much of the variation is due to the difference in the kind of ocean bottom and how much due to the selective power of the animal itself. It has seemed best, therefore, to leave this some- what heterogeneous series under this name. Localities: 79, 215, 223, 226, 229, 230, 225, 246, 249, 253, 264, 265, 281, 283, 284, 286, 290, 293, 298, 304, 308, 320, 316, 409, 410, 411, 413, 414, 416, 421, 423, 425, 426, 456, 460, 461, 462, 465, 468, 467, 471, 472, 473, 504, 505, 519, 539, 545, 546, 554, 547, 555, 1042, 2007, 2017, 2012, 2018, 2029, 2032, 2034, 2054, 2066.

Length up to 5.00 mm. Under this species have been placed numerous specimens such as those figured here, which are built largely from other foraminiferal tests. Such specimens vary considerably in form but in general have rapidly enlarging chambers with a pyriform shape and a distinct pro- tuberant neck. Localities: 290, 296, 447, 266, 278, 458, 251, 2001, 284, 281, 546, 238, 272, 55, 265, 2014, 2009, 82, 487, 331, 2072, 328. Distribution Station 546 places this species in shallow waters, low tide, off the coast of Ecuador. In the Galapagos Islands, off Chatham, it has been found at 400 fms. Off Central America and Mexico, numer- ous records indicate a depth range of 10 to 400 fms. Reophax excentricus Cushman Plate 3, Figs. 4-9 Reophax excentricus Cushman, Bull. 71, U. S. Nat.

Brady in the shorter chambers, com- pression of the test and elongate aperture without a neck. ‘The species occurs at numerous stations and often in considerable numbers retaining its characters unusually well for this genus. Lo- calities: 535, 298, 296, 250, 2000, 57, 505, 2009, 482, 2035, 2016, 2075, 290, 241, 293, 230, 278, 474, 294, 257, 242, 546, 540, 2018. Distribution—Numerous stations in the Gulf of California, with a depth range, 20 fms. in Agua Verde Bay to 140 fms. at the north end of Isla Partida; off Lobos de Afuera Island, Peru, and Gorgona Island, Colombia, with a depth range of shore to 22 fms. Reophax sp. (?) Plate)3;) Pig: 13 A very few specimens from locality 216 give characters which makes it seem different from any described species but material is not at present sufficient to warrant a full description and name. The specimens are very small and slender. They may possibly be allied to R. scotti Chaster. Distribution—Type locality is Petatlan Bay, Mexico, in 100 to 140 fms. Reophax dentaliniformis H. B. Brady Plate 4, Figs. 1-5 A few specimens in our collections have been placed under this specific name with some uncertainty. As the figures show, they repre- sent a considerable range in the amount of overlapping of the chambers, but all have the short neck and rather large aperture characteristic of this species and some of them seem rather close to Brady’s type figures. A glance at the literature will show what diverse series of forms have been placed by various authors under this name. Our specimens seem nearer to Brady’s types than many which have been referred here. Localities: 55, 251, 226, 286, 249, 241. Distribution—Mexico, off Guadalupe Island in 96 fms.; large numbers off North Isla Partida in 55 to 225 fms.; in the Gulf of Cali- fornia this species has been recorded as far north as San Pedro Nolasco Island in 48 fms. 64 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 EXPLANATION OF PLATE 7 Fics. 1.

Brady Plate 4, Fig. 6 A very few specimens are referred to this species. Most of them are incomplete but they strongly suggest this in their form. They are from localities: 55, 216, 522, 2016. Distribution —Mexico, in the Gulf of California off Point Escon- dido Bay in 138 fms. and North Isla Partida in 180 fms. Off the rocks of San Lorenzo Island, Callao, Peru, in 25 fms.

Sl, pl. 2, figs: 29, 30. Lacroix has described and figured a tiny species from the Medi- terranean and the Atlantic. Earland also records it from off the Falk- lands. Occasional specimens in our collections in size and general char- acters seem to fit well with this species but specimens are very rare. They are from stations 577, 586. Distribution—Off Cape San Francisco, Ecuador, in 15 fms.; Sechura Bay, Peru, in 10 fms. Genus AMMOFRONDICULARIA Schubert, 1902 Ammofrondicularia compressa Cushman and McCulloch, new species Plate 4, Figs. 7-13 Test one and one-half to two and one-half times as long as broad, very much compressed, generally rhomboid in front view, greatest breadth somewhat above the middle, periphery subacute; chambers in- distinct from the exterior, increasing rapidly in size as added, earlier ones narrow, later becoming very broad and chevron shaped; wall com- posed of sand grains and large flakes of calcareous fragments, surface rough; aperture narrow, elongate, terminal, without distinct neck. Length up to 3.00 mm; diameter 1.00-2.25 mm. Holotype (AHF no. 4) from locality 447. No. 1 CUSHMAN, MCCULLOCH: ARENACEOUS FORAMINIFERA 69 This species differs from Ammofrondicularia angusta Schubert in the broadly rhomboid form and much greater increase in size of chambers. Our species is characterized by its very rough wall composed of calcareous flakes rather roughly cemented and in some respects resem- bling Flabellammina but the earlier chambers are not coiled. Schubert has described a peculiar form for which he has erected the genus 4mzno- frondicularia. His specimen, however, consists of a section only and details of its full characters are lacking. Our species is very unique and we have referred it tentatively at least to Ammofrondicularia. It has occurred at numerous stations as follows: 248, 290, 296, 264, 299, 318, 447, 546, 2013, 2031, 2032, 2057, 256, 2018. Distribution.—Type locality, Cartago Bay, Albemarle, Galapagos Islands, in 32 fms. On the shore below sandy beach of Gorgona Island, Colombia; numerous stations in the Gulf of California in depths rang- ing from 15 to 81 fms. Family Ammodiscidae Genus AMMODISCUS Reuss, 1861 Ammodiscus pacificus Cushman and Valentine Plate 5, Figs. 1, 2 Ammodiscus pacificus Cushman and Valentine, Contr. Dept. Geol. Stanford Univ., vol. 1, no. 1, 1930, p. 7, pl. 1, fig. 1. Test large, planispirally coiled, proloculum nearly spherical, later coils covering about two fifths of the previous coil; chamber tubular, not compressed, the coils increasing slightly in diameter as added; suture distinct, depressed ; wall smoothly finished, consisting largely of reddish- brown cement with numerous fine angular particles of sand; aperture semicircular. Diameter up to 3.15 mm. This species was originally described from the Pacific and has proved to be rather common in our material occurring at the following localities: 136, 444, 328, 482, 488, 411, 207-2, 403, 73. Distribution—This investigation extends the range of this species from off San Pedro, California, southward along Mexico and into the region of Galapagos Islands where a number of records show a depth range of 9 fms. in James Bay, James Island, to 250 fms. at Cartago Bay, Albemarle Island. 70 ALLAN HANCOCK PACIFIC EXPEDITIONS VoL. 6 Ammodiscus minutissimus Cushman and McCulloch, new species Plate 5, Figs. 3, 4 Test very small, composed of comparatively few coils, periphery rounded, coils considerably overlapping; wall largely chitinous with few very fine sand grains, surface polished; aperture rounded, at the free end of the tubular chamber. Diameter 0.15-0.30 mm; thickness 0.10-0.15. Holotype (AHF no. 6) from locality 534. This species differs from Ammodiscus pacificus in the very minute size and the highly polished chitinous wall. It has proved to be a rather common and widely distributed species along the eastern coast of the Pacific occurring at the following localities: 57, 80, 82, 266, 281, 293, 299, 409, 410, 421, 460, 461, 462, 466, 534, 573, 574, 585, 1033, 1035, 1042, 2005, 2008, 2037, 2057, 2062, 2070. Distribution—Type locality, north of the Middle Chincha Island, off Peru in 18 fms. Numerous station records outline a range from San Francisco, California, in 37 to 105 fms.; in the Gulf of California, a depth range of 18 to 75 fms.; in the region of the Galapagos Islands, 9 to 80 fms.; off Peru from 18 to 100 fms.

This species in our material shows considerable variation in the material of the test from a nearly purely chitinous wall to one composed largely of fine arenaceous material on a chitinous base. Some of the very smooth thin forms resemble 4mmodiscus minutissimus in the char- acters of the wall. The species occurs at numerous stations as follows: Dey OF 943355 1046.4 20055 20572037, 2052, 202922065, 253, 510; 280, 265, 255, 205, 299, 254, 258, 226, 298, 461, 319, 2066, 2048, 2020. 72 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 Distribution—The stations listed above show that this species occurs off San Miguel Island, California; along Mexico, in the Gulf of Cali- fornia, off Costa Rica, off Panama, near Albemarle, Galapagos Islands; Gorgona Island, Colombia, and Sechura Bay, Peru.

Length 0.35-0.70 mm; breadth 0.25-0.50 mm; thickness 0.15- 0.20 mm. The types of the species were from Queen Charlotte Sound in 25 fms. It has proved to be one of the most common species in our ma- terial as will be seen by the list of stations. There is considerable varia- tion. Typical specimens have somewhat triangular chambers in side view which are usually flattened on the sides. The following variety is apparently related to these but has much more rounded chambers and a more open coil.

Diameter 0.45-0.65 mm. There are specimens from two localities only which may belong to this species; for the most part they are small and have only 5 chambers in the last-formed coil similar to our figure. Localities: 227, 2071. At some of our other localities the wall of the species has a con- siderable proportion of sponge spicules but this is apparently due to the condition of the ocean bottom at these localities. This form occurs at the following stations: 461, 226, A-16. It is particularly marked at sta- tions: 416, 413, 461. Distribution —Off Guadalupe Island, Mexico, in 200 fms. and off Cape San Lucas in 345 fms. The forms having sponge spicules show a range from Cordova, Alaska, to the Galapagos Islands, off Albemarle and Duncan islands. Haplophragmoides trullissatum (H. B.

This species has been found common in our material from locality 2070 but has not been seen elsewhere. The very smooth form shown in our pl. 6, fig. 9, occurs abundantly at Station 2014 and somewhat similar ones at 2001. These have been included in above species. Distribution.—It is probable that material from depths equal to the record off Guadalupe Island in 250 fms. will show a wide range for this species. Ihe records for the smooth form are from near North Isla Partida in 225 fms. Haplophragmoides tenuum Cushman Plate 7, Fig. 1 Haplophragmoides tenuis Cushman, Bull. Scripps Instit. Oceanogra- phy, lech: (Ser.,: vol. (1)! no. 10s 1927, \p./135, fig. 5, pl. 1: Test planispiral, close coiled, compressed, involute, umbilicate, pe- riphery rounded, chambers few, usually six in the last-formed coil, su- tures radial, distinct, slightly depressed ; wall very thin, composed of fine quartz grains with grayish cement giving a translucent appearance, smoothly finished; aperture a curved slit at the base of the apertural face. Length 0.45 mm; breadth 0.35 mm. This species is described from off the west coast of America and occurs very commonly in our material from this same general region. It is completely involute and the umbilical region very slightly de- pressed. The color is usually gray in all our specimens as in the types. It occurs at a large number of stations but shows very little variation: 80, 299, 509, 508, 513, 519, 504, 554, 516, 447, 1037, 2066, 2075, 1043, 2010, 2008, 2067, 332, 575, 2063, 59, 278, 290, 296, 298, 241, 237: Distribution—From Monterey Bay off Salinas River, south to Sechura Bay, Peru, and at Cartago Bay, Albemarle, Galapagos Islands. Haplophragmoides veleronis Cushman and McCulloch, new species Plate’ ¥7,)Figs 2 Test planispiral, very evolute, the last-formed coil overlapping only slightly, deeply umbilicate, periphery broadly rounded; chambers fairly distinct, numerous, 10-12 in the last-formed coil, increasing very gradu- ally in size as added, in the adult the last-formed chambers sometimes No. | CUSHMAN, MCCULLOCH: ARENACEOUS FORAMINIFERA 83 smaller than the preceding ones as the last-formed whorl decreases in height ; sutures fairly distinct, depressed only in the latest portion; wall finely arenaceous, smoothly finished; aperture a narrow elliptical open- ing near the base of the last-formed chamber, often with a slight lip. Diameter 0.65-0.80 mm; thickness 0.50 mm. Holotype (AHF no. 9) from Station 2070. This species differs from H. trullissatum in the very much more evolute form, lower coils in the adult and usually a larger number of chambers. It has occurred only at Station 2070 but they appear in con- siderable numbers showing very little variation in its characters. Distribution—Type locality is Guadalupe Island, in 250 fms. Haplophragmoides subinvolutum Cushman and McCulloch, new species Plate 7, Figs. 3-5 Test close coiled, somewhat depressed, sutures umbilicate, mostly involute, periphery rounded or somewhat angled; chambers distinct, 7 or 8 in the adult coil, slightly inflated, triangular in side view, increas- ing rather evenly in size as added; sutures distinct, depressed, sigmoid ; wall finely arenaceous, with much cement and occasionally larger frag- ments, very smoothly finished on the exterior; aperture a low arched opening at the base of the apertural face in the median line with a dis- tinct overhanging lip. Diameter 0.40-0.65 mm; thickness 0.15-0.30 mm. Holotype (AHF no. 10) from Station A-8. This species differs from H. columbiense in the more involute test, less compressed and in having the aperture at the base instead of in the apertural face. Localities: A-8, 557, 521, 510, 552, 2014, 55. Distribution.—Type locality, Excursion Bay, near Astoria, Puget Sound Cannery, collected at low tide.

Length up to 1.25 mm. Specimens referable to this species occur from numerous stations in our material. They are never so well developed as in some parts of the Atlantic but may be included under this name. The spiral suture in the coiled portion is well marked and the earlier coils are visible. Specimens occur at the following stations: 2054, 514, 318, 2061, 64, 321, 248, 2042, 2045, 245, 253, 280, 298, 2012, 2027, 215, 506, 2046, 2044, 2038, 2042, 52, 244, 255, 281, 294, 546, 325, 583, 2075. Distribution—vThe present records indicate a depth range from shore to 163 fms.; a geographical range from Point Prieta, Mexico, in the Gulf of California to Consag Rock, and on south to Gorgona Island and Port Utria, Colombia. Ammobaculites ineptus Cushman and McCulloch, new species Plate 7, Fig. 6 Test in the early portion coiled, later with the chambers very elon- gate, each making up one entire side of the test; chambers distinct, very slightly inflated in the upper part, greatly increasing in size and length as added; sutures distinct, slightly depressed at the upper end; wall finely arenaceous, smoothly finished, usually yellowish brown in color. Length 0.30-0.40 mm; breadth 0.12-0.15 mm; thickness 0.08-0.10 mm. Holotype (AHF no. 11) from locality 557. This species is a unique one differing from 4. cassis (Parker) in the greatly elongate later chambers enveloping the entire ventral side in the adult and the very smooth wall. This in some respects resembles the peculiar form figured by Millett [Journ. Roy. Micr. Soc., 1899, pl. 5, fig. 6 (not 4, 5, 7)] from the Malay Archipelago. In our collection the species occurs at localities 557 and 582. Distribution —Type locality, Pitas Bay, Panama, in 12 fms.

Length 0.50- 0.75 mm; breadth 0.20-0.30 mm; thickness 0.10-0.12 mm. Holotype (AHF no. 12) from locality 2017. This species differs from 4. cassis (Parker) in the involute coiled portion, obscure sutures and chambers, and the very slender adult por- tion. This species in some respects resembles 4. calcareus (H. B. Brady) but is a much smaller species and much more irregular. It is widely distributed in our collections and shows considerable variation as indi- cated in our figures. The final chambers sometimes appear as if irregu- larly biserial. Localities: 252, 250, 293, 2029, 244, 298, 2054, 2017, 296, 2018, 2066, 2057, 2014, 2007, 2039, 255, 333, 583, 585, ???38: Distribution.—Fype locality, Point Escondido Bay, Lower Cali- fornia, Mexico, in 20 fms. Numerous stations in the Gulf of California and southward to San Francisco Bay, Ecuador. Ammobaculites agglutinans (d’Orbigny) From a single locality “Penang,” Station 92, there are three speci- mens that probably belong to this species. They are close coiled at the base with an umbilical depression, the later portion uncoiled, cylindrical, and the wall rather coarsely arenaceous. Distribution.—Penang, Malay Peninsula, low tide.

Gaudryina (Pseudogaudryina) atlantica (Bailey) var. pacifica Cushman and McCulloch, new variety Plate 9, Figs. 1, 2 Variety differing from the typical in the much smoother surface, smaller size and more nearly horizontal sutures. Holotype of var. (AHF no. 14) from locality 230. The variety also occurs at localities 2005, 2010, 2064, 2065, 230, C-9. There is a considerable amount of variation in this form as our figures indicate and there are intermediate specimens that seem to indi- cate that it is but a varietal form. Distribution.—Type locality, off San Benito Island, in 121 fms. Additional stations off Mexico, including the Inner and Outer Gorda Banks, in 50-82 fms. At Arvila Pier, California, it was collected in 7 fms. Genus RUDIGAUDRYINA Cushman and McCulloch, new genus Test in the early stages triserial, at least in the microspheric form, followed by a biserial series as in Gaudryina and in the adult with the chambers in an irregular spreading series; wall finely arenaceous, firmly and smoothly cemented; aperture in the adult chambers generally termi- nal, rounded, often with a slight lip. Genoholotype, Rudigaudryina inepta Cushman and McCulloch, new species This genus is evidently derived from Gaudryina by the addition of the peculiar irregular growth which is often much greater in size than the original biserial portion.

Test elongate, very slightly tapering, rounded in transverse section, sides nearly parallel for most of their length, earliest whorls with more than three chambers, soon developing three chambers in a whorl which continues throughout the rest of the development; chambers distinct, slightly inflated, increasing very slightly in size as added in the adult; sutures distinct, depressed, sometimes filled and obscured; wall finely arenaceous, with a few coarse grains and much cement; aperture at the inner margin of the last-formed chamber, arched. No. | CUSHMAN, MCCULLOCH: ARENACEOUS FORAMINIFERA 97 Length up to 1.10 mm; breadth 0.25-0.28 mm. This is a more slender species than E. advena (Cushman) and the texture of the wall is much finer as there is a larger amount of cement. It occurs at the following stations: 508, 114, 285, A-19, 232, 283, 299, 275, 207, 238, 2070, 416, 2066, 2029, 413, 553, 227, 474, 226, 519, 2037, 2024, 2063, 285, 2065, 2061, 2033.

Test short and broad, circular in transverse section, tapering throughout except in the last two pairs of chambers in the largest adults, where the sides are nearly parallel, earliest whorl with four or five chambers, later with a short triserial stage, and the adult biserial, aper- tural end convex; chambers distinct, not inflated, in the adult of rather uniform size and shape, not overlapping, the interior divided by numer- ous radiating partitions near the periphery; wall coarsely arenaceous, finely perforate, with an outer thin coating, smoothly finished, often polished; aperture a low, arched opening, at the inner margin of the last-formed chamber. Length 2.20 mm; diameter 1.35 mm. This species is close to JT. barrettii (Jones and Parker) which occurs in the tropical Atlantic but the Pacific form is smaller, and the test is more coarsely arenaceous. The interior shows the early stages more primitive, with the divisions of the chambers not developed as early as in the Atlantic species. It has occurred at a number of our sta- tions: 226, 228, 553, 554, 541, 275, 286, 73, 283, 285, 505, 227, 540, 207, 426, 223, 278, 2024, 2065, 2063, 2064, 2033, 2035, 2010, 2029, 2005, 584, 587, 332. Distribution —Off Guadalupe Island in 65 fms., southward to Gorgona Island, Colombia, in 20-60 fms. 98 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 Genus GOESELLA Cushman, 1933 Goésella flintii Cushman Plate 10, Figs. 4-9 Goésella flintii Cushman, Special Publ.

Test in the earliest stages composed of 4 or 5 chambers in a whorl, rapidly reducing to 3, in the adult usually with a short, biserial stage followed by a few uniserial chambers, often only 1-3; chambers distinct, inflated ; sutures distinct, depressed ; wall very coarsely arenaceous, with large, angular fragments, but rather smoothly finished; aperture in the adult large, rounded. Length up to 1.50 mm; diameter 0.50-0.60 mm. The types of this species are from 185 fms. off San Pedro, Cali- fornia. he species is widely distributed in our material. The megalo- spheric form quickly attains the uniserial stage and shows but a few triserial chambers in the earlier stages after the initial whorl of four or five. In the microspheric form the triserial stage is held much longer and some of our specimens are not yet uniserial and might be mistaken for Eggerella scabra (Williamson) if it were not for the large series available. ‘Che species occurs in our material from the following sta- tions: 82,\80, 57, 25; 215,)217,. 509, 2069, 69; 56, 67; 299, 2410 se. 2000, 1042, 1035, 2070, 242, 251, 227, 2016, 2008, 2009, 2014. Some of the specimens as shown in our plate 10, fig. 5, are much smoother with a larger amount of cement and a deep reddish-brown color. These resemble G. rotundata (Cushman) in some respects but have the typical aperture of G. flintii and probably represent different bottom conditions. There seem to be intermediate stages between the coarsely arenaceous specimens and those with the smoother wall. Distribution —From the locality of the holotype, off San Pedro, California, in 185 fms., the range is now extended to Farallone Islands, San Francisco, northward in 38 fms. and southward to Callao, Peru, in 210 fms. Goéseila parva Cushman and McCulloch, new species Plate 10, Figs. 13, 14 Test minute, the whole elongate and cylindrical or elongate fusi- form, the triserial stage continued often for nearly one third or one half the length; chambers fairly distinct, somewhat overlapping, in- creasing in height toward the apertural end, the last-formed chamber in the adult somewhat pyriform with a rapid reduction in diameter No. 1 CUSHMAN, MCCULLOCH: ARENACEOUS FORAMINIFERA 99 toward the apertural end; sutures only slightly depressed; wall rather coarsely arenaceous for the size of the test; aperture terminal, rounded. Length up to 0.30 mm; diameter 0.08-0.10 mm. Holotype (AHF no. 16) from locality 236. This species differs from G. flintii Cushman in its very small size, more slender test and fusiform shape. It is a fairly common species as the list of localities shows and at some stations seems to be abundant. It may easily be overlooked on account of its small size. It occurs at the following stations: C-9, 558, 416, 76, 216, 64, 2057, 2004, 2007, 5001263) 292.255, 2028, 2712238, 235.236, 258, 2067; Distribution.—Type locality is near Magdalena Bay, Mexico, in 19 fms. From Arvila, California, in 7 fms. to La Plata, Ecuador, in 10 fms. Genus CRIBROGOESELLA Cushman, 1935 Cribrogoésella pacifica Cushman and McCulloch, new species Plate 10, Figs. 10-12 Test elongate, subcylindrical, increasing in size slowly, often slightly reduced in diameter immediately after the triserial stage, uniserial stage making up much the greater part of the test, often distinctly curved; chambers fairly distinct, especially in the later portion, 2 or 3 times as broad as high, slightly overlapping, increasing in size only very gradu- ally as added; sutures mostly indistinct except in the later portion where they are slightly depressed ; wall rather coarsely arenaceous but smoothly finished; aperture in the adult becoming multiple, in some specimens with as many as 6 or 8 rounded openings in the terminal face of the last-formed chamber. Length up to 4.00 mm or more; diameter up to 1.00 mm. Holotype (AHF no. 17) from locality 2070. This species differs from C. robusta (H. B. Brady) in the much smaller proportion of the triserial stage, more coarsely arenaceous test, larger pores in the cribrate aperture, and the curved test in the larger forms. The early stages have but a single aperture but the larger curved forms have several and a very long uniserial stage. This is the first record of this genus in the Pacific. It occurs at the following stations: 474, 475, 488, 2070, 487. Distribution—Type locality is off Guadalupe Island, in 250 fms. In the Galapagos Islands; stations show a range from off Tower at 120 fms., off Hood, 160-170, and off Chatham, a depth range of 400 fms. 100 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 Genus LISTERELLA Cushman, 1933 Listerella pallida (Cushman) Plate 10, Fig. 17 Clavulina communis d’Orbigny, var. pallida Cushman, Bull.

Length 2.00 mm; diameter 0.40 mm. The types of this species are from off the west coast of America but typical species have occurred at only two of our stations 2070 and 227 but there are good series from both stations.

Our series of figures shows the very great amount of range in ma- terials of which the wall of the test is made in this species. ‘This varies from nearly pure, coarse sand grains to large, flaky, calcareous frag- ments. When compared with the same stations from which Reophax and other arenaceous forms show similar characters, it is evident that bottom conditions and the available material very largely account for this wide range. The sutures are almost completely hidden in those specimens with very rough flaky exteriors and often in those composed largely of sand grains, but enough specimens show the sutures and chambers to warrant placing the whole series under this specific name. This is one of the most common and widely distributed species in our collections occurring at the following stations: 2027, 2026, 2046, 2013, 2061, 2062, 2044, 2067, 298, 245, 255, 244, 2047, 248, 2028, 557, 300, 323, 324, 286, 320, 215, 319, 254, 547, 546, Lowe-1, 290, 265, 253, 2A, 200; 2087, 307; S11; (321) 264, 284. 285.503": 2012281" 2021; 112 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 2025, 2030, 2032, 2038, 2055, 2057, 2035, 2046, 2054, 282, 217, 519, 409, 413, 513, 534, 509, 254, 238, 278, 260, 264, 508, 237, 271, 272; 305, 554, 555, 539; H-25, 583, 252;280, 296, 268, 258, 266, 2395292. 2048, 2050, 2042, 2045, 2039, 2037, 2031, 2034, 2023, 2029, 2015, 2020, 2007, 2008, 584, 585, 331, 330, 2075, 333, 581, 473, 249.

This seems to be a defi- nitely selective character as both species were found occasionally at the same station without any real intermediate stages. It has a wide distri- bution according to the published records. In our material it has oc- curred at the following stations: 1047, 1046, 226, 283, 299, 441, 461, 227, 80, 2070, 2005, 2051, 2063, 2064, 2010, 2065, 1037. Distribution —In Monterey Bay in 85 fms.; in Tagus Cove, Albe- marle Island, Galapagos, in 80 fms.; in the Gulf of California, off San Pedro Nolasco Island, in 60 fms.; off Catalina, at Long Point in 120 fms.

These seem in every way identical with the specimens fig- ured by Brady in the Challenger Report. There are numerous Recent records for this species but most of them are unaccompanied by figures. The Recent species is not the same as the Cretaceous one described by d’Orbigny. It occurs also at localities 2034, 2065, 2017, 2009, 2044, 2070, 2057. In our material there are a very few specimens attached to echinoid spines or to sponge spicules, one of which is figured. These are very slender, perhaps due to the small amount of surface and may represent another species. Material was not in sufficient quantity to be certain of this. The slender forms are from localities 2005, 1046. Distribution.—Type locality, off Ildefonso Island, Mexico, in 55 fms. The range continues as far as Consag Rock in the Gulf of Cali- fornia; off Lower California, Mexico, on the ocean side northward to San Miguel, in 120 fms. for the slender form of this species. ‘ ; Oe a OMIA 4 i iE AA aT hee oe.

G. LALICKER and IRENE McCuLtocu This is the second report of a series of papers presenting the results of studies being made on the foraminiferal collections of the Allan Hancock Foundation, The University of Southern California. Most of the fora- minifera discussed in this paper were collected in shallow waters on the seven major cruises of the Velero III, under the command of Captain Allan Hancock, into tropical waters of the eastern Pacific beginning at San Pedro, California, and continuing southward to the Bird Islands off Peru. The stations where specimens of Textulariidae were found are listed at the end of the discussion for each of the species described in this paper. Such lists refer to the tables of stations for bottom samples given in the first report. (See pp. 3-30, J. A. Cushman and Irene McCulloch, A report on some Arenaceous Foraminifera, Allan Hancock Pacific Ex- peditions, 1939, Vol. 6, no. 1, pp. 1-113, pls. 1-12.) Some very interesting facts concerning the distribution and migra- tion of a number of species of foraminifera have come to our attention in the course of this study. Textularia articulata d’Orbigny, which has been reported as living off the west coast of France, is living also off the west coast of the Americas from California southward to Peru. This species, which is common in Miocene sediments of the Vienna Basin, France, Florida, and New Zealand, is established as one of the group having world-wide distribution. 7. calva Lalicker, which has been noted only in the vicinity of the West Indies and in the Caribbean Sea, has a wide distribution in the Pacific Ocean. T. lythostrota (Schwager), which is present in Pliocene sediments of Kar Nicobar and New Guinea, has been found in these collections. Of still greater interest is the pres- ence of so many of d’Orbigny’s species from the vicinity of the West Indies. 7’. agglutinans, T. candeiana, T. conica, and T. saulcyana are rather common in these collections. These species may have migrated before the uplift of a land bridge between North and South America during Pliocene time or during one of the warm interglacial stages of Pleistocene time when the level of the sea was higher than at the present time. [115] 116 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 The results of studies on the extensive collections of the Allan Han- cock Pacific Expeditions in other fields are pointing in the same general direction, particularly with reference to new species. The results so far indicate that the majority of new species is to be expected in the Gulf of California and in the vicinity of the Galapagos Islands. T. astutia is restricted to the waters of the Gulf of California. T. orbica, T. lauta, T. ramosa, and T. vola have been found only in the vicinity of the Galapagos Islands. Since there is a possibility of collecting more material from year to year, a certain amount of material containing new species has been set aside for the time being to avoid later difficulties. The holotypes and paratypes of the new species described in this report are a part of the collections of the Allan Hancock Foundation, The University of Southern California, Los Angeles. Paratypes are to be deposited in the U. S. National Museum, Washington, D.C., and in the Cushman Laboratory for Foraminiferal Research, Sharon, Mass.

Test compressed, somewhat longer than broad, subrhomboidal in front view, subrectangular in top view, thickest in apertural chambers, periphery acute ; chambers numerous, very low and broad, the upper mar- gin of each one somewhat thickened and coarsely arenaceous, the lower portion concave and less roughened, so that the surface of the test is com- posed of an alternating series of raised ridges and smoother depressions; wall coarsely arenaceous, composed of calcareous fragments and much calcareous cement; aperture a low, narrow opening at the inner margin of the last-formed chamber, in a deep re-entrant. The initial end of this species is rounded, making it appear much like a Spiroplectammina. However, a detailed examination with dilute acid of several specimens of this species from the Pliocene sediments of New Guinea and from the Pacific Ocean shows clearly that the initial portion is not planispiral. This species has been recorded from Pliocene sediments in Kar Nico- bar and New Guinea. It has been noted at several localities in the Pacific Ocean and is present at the following Hancock Expedition stations: 482, 487; and the Manila locality. Fics. 15. 16. 17. 18. 19. 20.

Test small, triangular in front view, nearly circular in top view, early portion of test somewhat compressed, later portion broadly rounded; chambers numerous, low and broad, apertural chambers flattened, early chambers somewhat overlapped by later ones; sutures distinct, slightly de- pressed, nearly straight and horizontal; wall rather smooth, composed of very fine sand grains cemented with calcareous cement; aperture a low, broad opening at the base of the inner margin of the last-formed chamber in a slight re-entrant, and a faint lip on some specimens. Length of holo- type, 0.35 mm.; maximum width, 0.49 mm.; maximum thickness, 0.36 mm. Holotype (AHF no. 26) from Hancock Expedition Station 412, lati- tude 0° 59’ 15” S., longitude 90° 20’ 30” W., Galapagos Islands, depth 111 fms. This species has been noted also at Hancock Expedition stations 414, 419, 478, and 481. It is abundant at the type locality, but is quite rare at the other stations. This is apparently the same species that H. B. Brady identified as Textularia trochus d’Orbigny, from the Admiralty Islands and New Guinea. T. trochus d’Orbigny has been definitely assigned to the genus Marssonella. Distribution —Off Tower Island, Darwin Bay, in 17 fms.; off Chatham Island, Wreck Bay, in 26 fms.; off Albemarle Island, Cartago Bay, in 12 fms.; off Bindloe Island, Galapagos, in 56 fms.

Length, up to 3.00 mm.; width, up to 2.00 mm.; thickness, 0.50 mm. This species was originally described by Cushman from the Miocene of the Panama Canal Zone. It is very abundant in the Miocene of Mex- ico, Texas, and Louisiana and has been noted at the following Hancock Expedition stations: 202, 203, 215, 317, 318, 325, 327, 329, 331, 332, 502; 503, 504;°509; 556, 558;\577, 578, 579, 2026, 2027, 2038, 2041, 2046, 2048, 2054, 2055, 2056, 2059, 2060, 2061, 2062, 2073, 2075, and 2078. A large number of specimens from the Esperson well, Cameron Co., Texas, have been examined by the senior author. They are very similar to specimens of T'extularia panamensis Cushman from the Miocene of Mex- ico and the Panama Canal Zone and should be assigned to that species. Distribution—Numerous stations in the Gulf of California with a depth range of 2-32 fms., southward off Central America, Ecuador, and Peru, in 9 to 47 fms.

CUSHMAN and IRENE McCuLiLocH This is the third of a series of papers presenting the results of studies being made on the foraminiferal collections of the Allan Hancock Foun- dation, The University of Southern California. In the first of these reports the localities for bottom samples were organized into definite tables (See pp. 3-30). The bottom samples col- lected since 1939, together with a special collection of earlier bottom samples procured by Miss Louise Hathaway, a student of The University of Southern California, are organized into tables in this report as continu- ations of those on pp. 3-30. Owing to the increasing number of mud samples from scattered areas under the heading of “Miscellaneous,” these are now numbered as the ‘‘6” series.

Distribution —Most of the previous records for this species are from the Miocene of California. The living specimens seem to be identical with the fossil ones. The depth range is from 18 to 55 fms.; off Colombia, in 19 fms. at La Libertad, and in 50 fms. at Port Utria. Nonion hancocki Cushman and McCulloch, new species Plate 17, Figs. 4, 5 Test nearly circular in side view, very much compressed, umbilical region slightly depressed, periphery subacute; chambers distinct, numer- ous, 15 to 18 in the adult coil, very low and broad, of uniform shape, in- creasing gradually in breadth as added, height changing very slightly, not inflated; sutures very distinct, curved, strongly limbate; wall smooth, finely perforate; aperture a narrow, low opening at the base of the aper- tural face. Length 0.70-0.80 mm; breadth 0.52-0.65 mm; thickness 0.20 mm. Holotype (AHF no. 32) from locality 561. This species differs from Nonion pizarrense W. Berry, in the larger number and lower chambers and the very strongly limbate sutures. Distribution —The type locality, Station 561, is San Juan Bay, Peru, in 30-40 fms.

Distribution.—The types of this species are from off Plymouth, Eng- land. It is somewhat surprising to find this species in our material, but others are known to have a distribution somewhat similar in cold water. The smoother form figured (Fig. 7) may also be included within the limits of variation of this species, at least pending the finding of additional material. hese localities record a range beginning with the Channel Islands, off San Pedro, to Peru, with a depth variation between 4 and 45 fms. Nonionella japonica (Asano), var. mexicana Cushman and McCulloch, new variety Plate 17, Fig. 10 Variety differing from the typical in the smaller size, rounded periph- ery, and the parallel sides of the apertural face. Length 0.30 mm; breadth 0.20 mm; thickness 0.05 mm. Holotype of variety (AHF no. 33) from locality 223. This is very close in most of its characters to the species described and figured by Asano from the late Tertiary of Japan. Stations: 109, 112, 113, 222, 223, 409, 466, 468. Distribution.—The type locality for this new variety is Sulphur Bay, Clarion Island, Mexico, in 53 fms. The other localities ranging from the Channel Islands off California to the Galapagos Islands record a depth range from 10 to 34 fms.

Variety differing from the typical form in the stellate character of the lobate ventral end of the last-formed chamber which develops short fingerlike processes over the previous sutures. Stations: A-1, A-2, A-4, C-10, 24, 39, 58, 73, 1052. Distribution.—The types of this variety came from off San Pedro, California, at depths of 35-50 fms. These localities range from shallow waters off Cordova, Alaska, in 2 fms. to the area off Guadalupe Island, Mexico, in50 fms. Nonionella basiloba Cushman and McCulloch, new species Plate 18, Fig. 3 ‘Test small, dorsal side flattened, ventral side in the adult very convex, periphery rounded to subacute; chambers about 10 in the adult whorl, in- creasing rather rapidly in size as added, all visible on the dorsal side, on the ventral side with the later chambers developing a very large basal lobe which is inflated and comprises a large part of the test in ventral view, extending down to the periphery and in peripheral view forming a distinct portion offset from the earlier whorls; sutures distinct, not depressed, somewhat curved; wall smooth, finely perforate; aperture at the periph- ery, low, extending under the basal lobe on both sides. Length 0.25-0.30 mm; breadth 0.18 mm; thickness 0.15 mm. Holotype (AHF no. 35) from locality 136. ‘This species has a great development of the later chambers on the ventral side, resembling Nonionella jacksonensis Cushman, of the Eocene but differs from that species in the more acute periphery, more rhomboid form, and greater development of the ventral lobe. Stations: 136, 343, 516, 517. NO. 3 CUSHMAN AND MCCULLOCH: SOME NONIONIDAE 163 Distribution.—Type locality, Station 136, is off San Clemente Island, California, in 50 fms. Other records extend the range southward, at Bahia Honda, Panama, in 32 fms. and off the coast of Colombia, in 55 to 116 fms. Genus CUSHMANELLA Palmer and Bermudez, 1936 Cushmanella primitiva Cushman and McCulloch, new species Plate 18, Figs. 6-8, 10 Test bilaterally symmetrical, compressed, periphery rounded, height often twice the breadth, early portion with the chambers in a single series, later with supplementary ones, smaller and alternating with the larger primary ones, the test tending slightly to uncoil in final stages; chambers distinct, the primary ones increasing rapidly in size as added, slightly inflated in the adult, supplementary chambers small and irregular in size, developed slightly more on one side than on the other; sutures very dis- tinct, slightly limbate, curved, becoming slightly sigmoid in the later portion in some specimens; wall thin, translucent, smooth, very finely perforate; aperture at the base of the chamber, low, and occasionally a supplementary one slightly above the base of the apertural face, rarely higher up and apparently connecting with an internal tube. Length 0.30-0.45 mm; breadth 0.20-0.30 mm; thickness 0.12-0.15 mm. Holotype (AHF no. 36) from locality 418. This species differs from Cushmanella brownii (d’Orbigny) in the more compressed and smaller test, larger number of chambers, and more primitive apertural characters. While the aperture in the middle of the apertural face is rarely seen in this species, its other characters show its relationship to the Atlantic species. It is evidently more primitive. There is a distinct tendency toward uncoiling in the later stages, particularly of the megalospheric form. An- other species from the Pacific, Nonionella translucens Cushman, found in the Indo-Pacific region seems possibly an intermediate form between Nonionella and the species described here. Fig. 9 shows a peculiar form possibly related to C. primitiva. Stations: 222, 223, 2082, 339, 342, 343, 409, 418, 422, 423, 436, 460, 461, 463, 466, 468, 469, 470, 473, 500, 547, 556, 558.

Test of large size for the genus, about 214 times longer than wide in peripheral view, lenticular, completely involute, the umbilical regions with a medium-sized, slightly projecting, rounded boss of clear shell ma- terial, the surface of which is set with 10 to 12 small, shallow, rounded pits, periphery sharply angular but not sharply keeled, sometimes becom- ing slightly lobulate and blunter in the last portion of the adult coil; chambers very numerous, 20 to 40, long and narrow, the last few often inflated, forward part slightly raised, giving a radially ribbed appearance; sutures somewhat sigmoid, the middle portion of each nearly radial, often partially obscured by the retral processes, set with pores, those of the earlier ones indistinct but later ones with large and deep pores; wall finely perforate, with about 12 relatively long retral processes extending well up onto the side of the next added chamber, appearing as fairly widely spaced, low elevations of the wall in the earlier chambers but as thicker and more rodlike structures in the later chambers; aperture a row of small openings at the base of the apertural face, which is low, sagittate, the sides often slightly concave, the ends pointed. 176 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 Diameter up to 3 mm; thickness 0.40-1.00 mm. Stations: C-10, 60, 61, 67, 76, 136, 1007, 1023, 1050, 1061, 1062, 1064, 204, 211, 230, 258, 278, 280, 284, 285, 292, 2011, 2020, 2021, 2023, 2024, 2033, 2048, 2082, 2083, 2084, 322, 422, 423, 500. Distribution.—This species is recorded as very widely distributed. The specimens from the Eastern Pacific, while apparently typical in most characters, average much smaller than from more tropical waters. An analysis of these station localities shows a geographical range from Ecua- dor into the Gulf of California and northward to points off the coast of California. The depth range is from 2 to 130 fms. Elphidium crispum (Linné), var. suberispum Cushman and McCulloch, new variety Plate 20, Fig. 6 Variety differing from the typical in the smaller size, fewer and higher chambers, shorter and fewer retral processes, and the less distinct, usually imperforate umbo. Holotype of variety (AHF no. 40) from locality 421. This variety, although occurring with the typical, is simpler in all respects. Stations: 111, 222, 311, 317, 322, 406, 409, 411, 421, 452, 460, 463, 466, 467, 468, 472, 500, 616. Distribution Type locality, Station 421, is Anchorage, South Sey- mour Island, Galapagos, in 13 fms. An analysis of station localities indi- cates that two records are off the coast of California in shallow waters; one off Socorro Island, Mexico, in 4-10 fms.; three off Costa Rica in 1-10 fms.; numerous stations off the Galapagos Islands in 13-65 fms.; one off La Plata Island, Ecuador, in 10 fms. This species was also found in a bottom sample, 616, from West Hole Island, Whit Sunday Passage, East Coast of Australia, at low tide. Elphidium pustulosum Cushman and McCulloch, new species Plate 20, Figs. 7-10 Test nearly circular in side view, amount of compression variable, periphery acute, keeled, often slightly lobulate, denticulate, umbonal re- gion slightly depressed; chambers distinct, numerous, 12 to 15 in the adult coil, of uniform shape and increasing very gradually in size as added, the edges of the apertural face strongly raised into a conspicuous ridge; sutures strongly curved, retral processes very distinct, usually extending No. 3 CUSHMAN AND MCCULLOCH: SOME NONIONIDAE be entirely across the chamber, 10 to 12 in number; wall reticulate on ac- count of the raised ridges and retral processes, the umbilical region often with papillae and in some specimens the early portion of the whorl covered with fine papillae; aperture composed of several small openings at the base of the apertural face of the last-formed chamber. Length 0.90-1.15 mm; breadth 0.65-0.90 mm; thickness 0.30-0.50 mm. Holotype (AHF no. 41) from locality 447. This species differs from E. crispum (Linné) in the absence of an umbonal boss, fewer chambers and very roughened surface. It is common in our collections and distinctive in appearance. Stations: 401, 409, 423, 435, 437, 438, 441, 442, 447, 456, 458, 459, 460, 461, 463, 464, 465, 467, 469, 470, 471, 472, 478, 479. Distribution—All of the localities listed with the exception of 423 are off the Galapagos Islands, with a depth range from 9 to 80 fms. Stations 422, 423, and 425 (p. 23) are bottom samples from Socorro Island, Mexico, made by the Velero III, on the 1934 Expedition, to the Galapagos. The inclusion of bottom samples from off Mexico with those of Galapagos was not discovered soon enough to justify the changes neces- sary to correct the station numbers. This species is recorded at Station 423 in 13 fms. Genus ELPHIDIELLA Cushman, 1936 Elphidiella hannai (Cushman and Grant) Plate 20, Fig. 11 Elphidium hannai Cushman and Grant, Trans. San Diego Soc.

Test of medium size, the diameter about twice the thickness, periphery rounded but not broad, umbilical region flattened or very slightly concave, rarely slightly convex ; chambers distinct, 12 to 15 in the last-formed coil, not inflated ; sutures very distinct, limbate, flush with the surface, with a line of very fine pores, sometimes irregularly doubled, continued to the center of the umbilical region, the sutures appearing as darker curved lines on the lighter mass of the thick but very finely perforate wall ; aper- ture consisting of a series of very fine pores along the base of the apertural 178 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 face and occasionally others scattered irregularly over the apertural face. Diameter 0.80-1.00 mm; thickness 0.40-0.50 mm. This is the only species of the genus known from the West Coast of America, but is fairly common as a living species and is recorded from the Pleistocene and Pliocene of California. Stations: A-1, A-2, A-3, A-4, A-6, A-15, A-20, A-22, A-23, V-3, Silex, Oregon, C-1, C-9, 225, Penang. Distribution.—These localities indicate a continuous range from off the coast at Cordova, Alaska, southward to the east side of Cedros Island, Mexico, in shallow waters. The bottom sample from Penang, low tide, also contained a few specimens which have been placed with those from this edge of the Pacific Ocean.

CUSHMAN and IRENE McCULLOCH THE UNIVERSITY OF SOUTHERN CALIFORNIA PUBLICATIONS ALLAN HANcock PACIFIC EXPEDITIONS VOLUME 6, NUMBER 4 IssUED JANUARY 19, 1942 THE UNIVERSITY OF SOUTHERN CALIFORNIA PRESS Los ANGELES, CALIFORNIA SOME VIRGULININAE IN THE COLLECTIONS OF THE ALLAN HANCOCK FOUNDATION (PLATES 21-28) Joseph A. Cushman and Irene McCulloch In this fourth paper presenting the results of studies being made on the foraminiferal collections of the Allan Hancock Foundation, The University of Southern California, the third list of station tables is in- cluded. These three tables are continuations of Table 6 (see pp. 9-11, 146-148) ; of Table 7 (see pp. 11-13, 148-150) and Table 8 (see pp. 13- 21, 150-152). With new material coming in constantly it has been im- possible to complete the study of any one family or genus. The foraminifera included in this paper mostly belong to the genus Bolivina and show a very considerable amount of variation. Figures on the plates show this variation to some extent and also the striking differ- ences in the megalospheric and microspheric forms of the same species. As in other foraminifera, the adult characters are taken on much earlier in the megalospheric form, and it is in the comparison of these adult cham- bers that the relationships between the two forms become apparent.

Length 0.50 mm.; breadth 0.12 mm.; thickness 0.10 mm.” This species described from the coast of California occurred at Station 231 in typical form. Distribution —The station record of 231, listed with the stations off Mexico, is off California, Smuggler’s Cove, Santa Cruz, 10 fms. This record is one of several which deviate from the general plan of labeling bottom samples at the Foundation. Genus BOLIVINA d’Orbigny, 1839 Bolivina acerosa Cushman, var. pacifica Cushman and McCulloch, new variety Plate 21, Figs. 2, 3 Variety differing from the typical in the somewhat larger size, lack of ornamentation of the early portion, and the distinct clear areas at the upper and inner portion of each chamber. Holotype of variety (AHF no. 42) from Station 60. The typical form of the species is from the Miocene of Haiti. The varietal form shows very little variation, although specimens are numerous at some of the stations. It has a wide range along the coast of the eastern Pacific. 186 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 Stations: A-2, A-15, 55, 60, 79, 80, 144, 468, 508, 516, 1006, 1009, 1015, 1068, 1095, 1096, 1097, 1100, 1101, 2000, 2093, 2107, 2113, 2116, 2134, 2140, 2149.

Test elongate, 214 to 3 times as long as broad, somewhat fusiform, greatest breadth toward the apertural end, periphery of the early portion acute, becoming rounded in the later portion, early portion strongly com- pressed, later portion somewhat more thickened ; chambers distinct, those of the early portion very low and broad, later increasing in relative height as added, so that toward the apertural end the last-formed chamber may be nearly as high as broad, slightly inflated, particularly in the later por- tion; sutures slightly limbate, particularly in the early portion, later somewhat depressed, somewhat curved, in the early portion forming an angle of about 30° with the horizontal; wall smooth, but distinctly per- forate; aperture narrow, elongate, opening on the base of the inner mar- gin of the last-formed chamber. Length 0.45-0.50 mm.; breadth 0.20-0.22 mm.; thickness 0.10-0.12 mm. The records for this species are all from the Miocene. Rare specimens occurred at stations 469, 1015, and 1069, but they may possibly be re- worked fossils. Distribution —Station 1015 is off Tyler Bay, Santa Cruz Island, in 32 fms.; Station 1069 is off Santa Rosa Island in 230 fms.; Station 469 is off Charles Island, Galapagos, in 10 fms.

Additional records are off Costa Rica, Ecuador, Kobe, Japan, and Singapore with a depth range from 10 to 19 fms. Bolivina aenariensis (Costa) (?) Plate 21, Fig. 12 There are a number of specimens similar to that here figured which may be referred with some question to Costa’s species. hey are all very similar and show little variation. Stations: 136, 422, 512, 583. Distribution —Station 136 is in shallow waters off San Pedro; Sta- tion 422 is off Socorro Island, Mexico.

Linn. Soc. London, ser. 2, vol. 11, 1916, p. 238, pl. 41, figs. 10-14 (?). Test from 114 to 2% times as long as broad, small, rather thick, periphery broadly rounded; chambers fairly distinct, slightly if at all inflated, much broader than high throughout, increasing gradually in size as added, the basal edge at the inner margin in the adult often develop- ing a definite lobe and re-entrant; sutures distinct except in the early portion, somewhat limbate, not depressed, strongly oblique, somewhat more so in the adult portion; wall finely perforate, with coarse surface ornamentation, which, in the early portion, consists of a rather coarse network, the edges of which are considerably raised above the surface, becoming finer and less raised toward the apertural end, the last pair of chambers often fairly smooth; aperture elongate, narrow. Length up to 0.50 mm.; diameter 0.18-0.20 mm. The types are from 4/batross D2677, 478 fms., off the Carolina coast. ‘This species somewhat resembles B. compacta Sidebottom, but the su- tures are different, and the ornamentation, particularly of the early por- tion, is much more pronounced. The shape of the two forms is also quite different. The Pacific specimens so far as our material shows are somewhat broader than the Atlantic ones, although there are intermediate speci- mens and the ornamentation and other characters are very similar. Stations: 403, 411, 412, 414, 461, 466, 472, 627, 629. Distribution.—The series of records from the regions of the Galapa- gos give a range of 15, 60, 111 fms. At both Kobe, Japan, and Singapore the bottom samples were collected from anchors. Bolivina argentea Cushman Plate 22, Figs. 2-6 Bolivina argentea Cushman, Contr. Cushman Lab. Foram.

Test elongate, 214 to 3 times as long as broad, very much compressed, periphery subacute, usually not keeled, the width after the first few chambers increasing slowly ; chambers very distinct, narrow in the young, in the adult about 214 times as long as broad; sutures oblique and curved, early ones limbate, later ones thin and somewhat depressed; wall very finely perforate, smooth except for the very base, which occasionally has a trace of one or more costae on the proloculum, and one or two follow- ing chambers; color of test light silvery gray, polished. Length up to 0.80 mm.; breadth 0.40 mm. The types are from Lydonia station 30, Lat. 7° 01’ N., Long. 81° 48’ W.., in 428 fms. It also occurs northward along the west coast of America at least as far as Oregon, and may possibly have been recorded as B. aenariensis from farther north. It occurs in the upper Pliocene of Cali- fornia in typical form, and has the same silvery gray test in well-preserved specimens. It is one of the characteristic and abundant species of the western coast of America. In our material this species has occurred at but few stations, but it is often difficult to separate it from Bolivina interjuncta Cushman, var. 67- costata Cushman, which may account for the many records of the former. Stations: 82, 260, 261, 473, 629, 634, 1069, 1070, 1077, 1083, 1095, 1096, 1097, 1099. Distribution —Mbost of the above records are for the regions off the Channel Islands and range in depth from 17 to 230 fms. In the Gulf of California the record is for 52 fms.; off the San Benito Islands it is 16-42 fms. A single record for Galapagos, Hood Island, is for 73 fms. The records for Port Said and Singapore are for less than 10 fms.

Length up to 0.9 mm.; thickness 0.16 mm.” ‘The types of this species are from the Miocene of Palos Verdes Hills, California. It has not previously been recorded as a living species, but there are numerous specimens in our collections that seem to belong here. It is a more fusiform, somewhat thicker species than B. pseudo- beyricht Cushman.

Distribution—Numerous records for the Gulf of California give a depth range from 6 to 160 fms. In Parker Bay, Costa Rica, the depth is 15 fms.; in the area north of Duncan Island, Galapagos, the depth is 111 fms.; for three stations off Colombia the depth range is 48 to 50 fms.

Length up to 0.75 mm.; breadth 0.25-0.30 mm.; thickness 0.12-0.15 mm. This species is widely distributed in the Pacific and elsewhere and is somewhat variable in shape. Stations: C-13, 53, 61, 62, 73, 80, 208, 228, 416, 423, 457, 460, 461, 466, 468, 469, 470, 472, 500, 534, 535, 539, 574, 1003, 1013, 1017, 1041. Distribution —An analysis of the stations shows a record for Mon- terey Bay, California, 25 fms.; near Catalina and San Clemente for 10 to 25 fms.; off Mexico in 17 to 50 fms.; a series of records off Ecuador and Peru in 10 to 100 fms.; and a series of records off the Galapagos Islands in 7 to 80 fms.

Test small, tapering, about twice as long as broad, broadest toward the apertural end in both front and side views, periphery broadly rounded; chambers numerous, earlier ones low and broad, later ones becoming gradually higher, until, in the last-formed ones, the height is often nearly equal to the breadth, slightly inflated ; sutures somewhat in- distinct, but appearing as irregular, angular lines between the sutures, pointing toward the aperture, since the suture line extends out onto the costae and backward at the same time; wall very coarsely perforate, with a few, sharp, raised, longitudinal costae, continuous over the sutures, usu- ally 5 or 6 costae on a side, last-formed chambers of each series usually smooth on the outer face; aperture narrow, elliptical, extending in from the base nearly in the median line. Maximum length 0.40 mm.; breadth 0.15 mm.; thickness 0.12 mm. This species was described by d’Orbigny from off the west coast of South America. It is abundant off the coast of Peru, and it is interesting to note that all of the stations which have this species are in this same region. 192 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 Because later authors have placed other forms under this name, there has been some confusion in regard to it, but the species as d’Orbigny described it is very distinctive and limited in its distribution. Stations: 323, 522, 529, 533, 534, 536, 537, 573, 574. Distribution—The above records place this species in Salinas Bay, Costa Rica, in 8 fms. and off the coast of Peru with a depth range from 6 to 100 fms.

Test small, depressed, broadest near the apertural end; chambers comparatively few, consisting of 8 or 10 pairs; wall very coarsely perfor- ate, the earlier chambers with a few coarse perforations near the basal margin, the adult chambers with the coarse perforations scattered over the general surface; chambers fairly narrow, but becoming higher toward the apertural end; sutures distinct, depressed, strongly oblique; aperture elongate, arched, in the median line, at the base of the last-formed cham- ber. Length 0.36 mm.; breadth 0.15 mm.; thickness 0.10 mm. The types of this species are from off Juan Fernandez. A few speci- mens in our collections seem to belong to this species. Stations: 61, 100, 313, 464, 469, 472, 502. Distribution—These records indicate a range beginning off San Francisco Island, Mexico, in 17 fms.; Secas Islands, Panama, in 25 fms.; three stations off Charles and Hood islands, Galapagos, in 10-15 fms.; and off La Libertad, Ecuador, in 15 fms.

Length 0.70-0.80 mm. ; breadth 0.25-0.28 mm. ; thickness 0.15- 0.18 mm. The types are from the Miocene, 2,040 feet stratigraphically above base of Modelo formation as exposed along road from Girard to Mohn Spring, Santa Monica Mountains, California. Numerous specimens from restricted areas off the coast of Mexico seem to be identical with the types of this species. Stations: 57, 59, 60, 62, 67, 2100. In some specimens there is a tendency toward a lobing of the sutures similar to that seen in Bolivina sinuata Galloway and Wissler, but the early stages are not the same. This is shown in our figured specimen. Distribution —All of these station records are off the tip of Lower California, Mexico, beginning with the Santa Maria Bay on the Pacific side, in 7 fms., and around Cape San Lucas to the region of Espiritu Santo in 150 fms.

Length up to 0.75 mm.; breadth 0.30 mm.; thickness 0.10 mm. The types of this species are from the Miocene. The specimen here figured from Station 1062 seems to be a recent one. There are two specimens from Station C-11 that are probably washed out from fossil beds as is indicated by the peculiar appearance of the wall and the broken edges. Abundant specimens from Station 1003 may also be fossils. Distribution —These records are off the coast of southern California in shallow water.

Test elongate, 2 to 214 times as long as broad, much compressed, pe- riphery sharp and keeled, gradually tapering, greatest breadth toward the apertural end ; chambers distinct, the earliest ones low and broad particu- larly in the microspheric form, gradually increasing in relative height as added, the later ones very slightly if at all inflated ; sutures fairly distinct, oblique, forming an angle of about 35° with the horizontal, strongly limbate; wall finely perforate, ornamented by several, very strongly raised, longitudinal costae, running nearly the entire length of the test, connected in the later portion by numerous, irregularly anastomosing, shorter costae of about the same strength; aperture elongate, narrow. Length up to 1.00 mm.; breadth 0.35-0.40 mm. ; thickness 0.08-0.10 mm. The types are from the Pleistocene, Lomita Quarry, Palos Verdes Hills, California. As a living species this is rare, much more so than the following variety. A fairly typical specimen is figured. Stations: 230, 1077, 1078, 2093, 2094, 2140, 2144, 2146, 2149, AVS T2152 021 53) NO. 4 CUSHMAN AND MCCULLOCH: SOME VIRGULININAE 195 Distribution.—Beginning at the region of San Benito Islands, Mexi- co, in 35 fms. and continuing on around into the Gulf of California with a depth range of 58 to 160 fms.

Variety differing from the typical in having the 2 costae nearest the middle most strongly developed, and continued for most of the length of the test, but no anastomosing costae present. Some of the Pacific material that has been referred to “Bolivina aenariensis Costa’’ may belong to this variety. There is considerable variation from forms such as Plate 23, Fig. 15, where but 2 costae are present, to the ones with additional lateral costae. The costae in the variety do not anastomose as in the typical form of the species. Stations: 55, 82, 200, 215, 217, 230, 251, 261, 409, 422, 506, 516, 517, 543, 583, 1078, 2097, 2100, 2101, 2134, 2156. Distribution —The records indicate a range beginning off Catalina in 147 fms., continuing southward along Mexico, into the Gulf of Cali- fornia, the region of the Galapagos Islands, and off Colombia in 10 to 225 fms.

Length 0.50 mm.; breadth 0.20 mm.; thickness 0.10-0.15 mm. This species is known mostly from about the British Isles. The Pacific specimens are somewhat less compressed, but when compared with the Atlantic specimens seem to be close enough to be included in the same species. Specimens are very rare in our material. Stations: 209, 329, 534, 1062. Distribution—The four records show a range from east of Gull Island off Santa Barbara Island in 21 fms.; the region of San Benito Islands in 13 fms.; Cocos Island in 40 fms.; off Peru in 18 fms.

Variety differing from the typical in the strongly raised and limbate sutures and the tendency of the chambers to become somewhat spinose at the basal angle. No. 4 CUSHMAN AND MCCULLOCH: SOME VIRGULININAE 201 The type is from the Miocene, 1,100 feet N. and 200 feet W. of S.E. corner of Sec. 7, T. 26 S., R. 10 E., Adelaida Quadrangle, California. The living specimens show a considerable range of variation as will be seen from our figures. Some of the specimens are very close indeed to the fossils as a comparison with the types shows. From these there is a tendency for the chambers to be lower and more in the test as a whole. The spinosity of the margin also is variable. Stations: 200, 509, 1049, 1080, 1082. Distribution —Off Santa Barbara and San Clemente islands in 110 to 160 fms.; off Tangola Tangola, Mexico; off Colombia in 18 fms.

Stations: 56, 57, 69, 516. Distribution.—F rom Los Frailes Point, Mexico, in 160 fms.; in the Gulf of California in 150 fms.; and off Colombia in 55 fms. Bolivina pseudoplicata Heron-Allen and Earland (?) Plate 25, Figs. 4-7 There are numerous specimens in the collection which seem related to B. subexcavata Cushman and Wickenden but which develop, as our fig- ures show, a distinct reticulation, particularly on the basal portion. These show a wide range of variation, but the Atlantic forms show fully as wide a range, and it may be that they are the same.

Test 2% to 3 times as long as broad, gradually tapering, much com- pressed, thickened along the median portion, periphery acute or even slightly carinate, initial end occasionally with a very slight apical spine; chambers numerous, distinct, slightly if at all inflated, much broader than high throughout, increasing only slightly in relative height toward Zi2 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 the apertural end; sutures distinct, often strongly limbate, strongly oblique, forming an angle of nearly 45° with the horizontal; wall coarse- ly perforate, the earliest portion, especially in the megalospheric form, with a few prominent costae; aperture narrow, elongate, the inner end slightly expanded. Length up to 0.75 mm.; breadth 0.25-0.30 mm.; thickness 0.08-0.10 mm. The types are from the Pliocene of Timms Point, San Pedro, Cali- fornia. It is common in the Pliocene and Pleistocene of southern Cali- fornia, and occurs in the Pliocene, Humboldt County, California. It oc- curs off the coast of California at various depths. The species is somewhat variable, on one hand tending toward the roughened, thick-walled condition of B. subadvena Cushman, and on the other hand tending to become smooth, and related to B. argentea Cush- man. This has proved to be a rare species in our material except at one station, 82, off Long Point, Catalina Island, in 147 fathoms, where it was abundant. Stations : 80, 82, 227, 634, 1070, 1077, 1079, 1080, 1083. Distribution—Additional records for this species place it off the Channel Islands in 127 to 300 fms.; near Guadalupe Island, Mexico, in 200 fms. At Port Said the bottom sample came from the anchor.

The types are from off the coast of southern California. In our col- lections this variety has been found to be common at some of the many stations and to keep its characters rather well. There is a tendency in some specimens toward Bolivina marginata Cushman, var. adelaidana Cushman and Kleinpell. Stations: 55, 59, 60, 79, 80, 83, 136, 144, 215, 230, 271, 422, 512, 513, 516, 517, 543, 1010, 1011, 1047, 1068, 1070, 1071, 1075, 1076, 1077, 1078, 1096, 1097, 1100, 1101, 2087, 2093, 2100, 2107, 2113, 2116, 2134, 2136, 2140, 2149, 2152, 2153. Distribution—The numerous station records extend from off Santa Cruz and Santa Barbara islands, California, in 14 to 127 fms. ; southward off Mexico and in the Gulf of California, Mexico, in 10 to 183 fms. 214 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 Bolivina subexcavata Cushman and Wickenden Plate 27, Figs. 3, 4 Bolivina subexcavata Cushman and Wickenden, Proc.

Test small, broadest near the apertural end, from which it rapidly tapers to the initial end, periphery rounded; chambers few, consisting of 6 or 8 pairs, the earlier ones broad and low, the later ones increasing in height toward the apertural end; sutures distinct, depressed, slightly oblique; wall very coarsely perforate with 2 regions, one at either side of the central area, which are excavated ; aperture an arched indentation at the base of the last-formed chamber in the median line. Length 0.32 mm. ; breadth 0.18 mm.; thickness 0.12 mm. The types are from off Juan Fernandez. It is a peculiar small form, marked by the coarse perforations, and the 2 distinct ridges close to the median line. It is similar to B. pseudoplicata Heron-Allen and Earland, from off the British Isles, and also resembles B. plicatella Cushman, but has a much less developed sculpture than either. Similar specimens occur widely distributed in the Tropical Pacific. In our material the species occurs at numerous stations and seems to grade into the form here referred to B. pseudoplicata. Stations: 61, 76, 136, 213, 232, 233, 323, 413, 466, 469, 472, 500, 502, 503, 539, 1009, 1041, 1062, 2066. Distribution.—In shallow waters from Monterey, California, in 25 fms., southward off the Channel Islands in 20 to 52 fms.; off Mexico and in the Gulf of California in 9 to 22 fms.; off Galapagos in 10 to 35 fms. ; and off Ecuador in 10 to 19 fms. Bolivina tongi Cushman, var. filacostata Cushman and McCulloch, new variety Plate 27, Figs. 7-11 Variety differing from the typical in the more highly ornamented test which in the later portion particularly consists of many fine, threadlike costae. Holotype of variety (AHF no. 45) from Station 461. When compared with the types of B. tongi Cushman from the Mio- cene, the similarity is very striking; but the living form, which in some NO. 4 CUSHMAN AND MCCULLOCH: SOME VIRGULININAE 21S specimens has the ornamentation largely confined to the sides of the test, is usually more highly ornamented on the later chambers with very deli- cate threadlike costae. It occurs at many stations and is often found in considerable numbers. Stations: 39, 55, 80, 136, 226, 227, 241, 256, 258, 259, 260, 264, 299, 329, 343, 409, 410, 412, 413, 414, 417, 461, 466, 468, 472, 473, 474, 478, 504, 512, 514, 573, 1008, 1011, 1068, 1072, 1075, 1076, 1100, 2087, 2097, 2098, 2100, 2113, 2116, 2133, 2134, 2136, 2137, 2140, 2149, 2152, 2453, 2154,,2156. Type locality —Off Tagus Cove, Albemarle Island, Galapagos, in 80 fms. Distribution —These stations record this species at numerous places in the Gulf of California in 8 to 200 fms.; off Catalina in 180 fms. and southward off Central America in 5 to 46 fms.; off the Galapagos Islands in 9 to 175 fms. Bolivina torqueata Cushman and McCulloch, new species Plate 27, Figs. 5, 6 Test small, twisted, often strongly so, early portion compressed, later irregularly rhomboid in section, sides slightly concave, periphery in the adult broad and truncate; chambers distinct, numerous, increasing rather regularly in size as added, little if at all inflated ; sutures distinct, oblique, somewhat limbate, little if at all depressed ; wall coarsely perforate ; aper- ture an oblong opening in the median line of the apertural face of the last- formed chamber with a distinctly thickened rim. Length 0.40-0.50 mm.; breadth 0.20-0.25 mm.; thickness 0.12-0.16 mm. Holotype (AHF no. 46) from Station 470. This species differs from Bolivina rhomboidalis Millett in the very much twisted test, the early compressed portion, and the strongly limbate sutures. The species occurs in considerable numbers at numerous stations and shows much variation in the amount of twisting of the test. The coarse perforations give a very rough appearance to the surface of the test. Stations: 208, 222, 227, 228, 418, 457, 466, 469, 470, 472, 473, 503, 1003, 1008, 1013, 1017, 1052, 2153.

Our specimens have a tendency to be slightly more spinose than the types and in this respect resemble somewhat Bifarina elongata Millett. Station: 616. Distribution—The material from which these specimens were ob- tained was collected at low tide on West Nole Island, Whitsunday Pas- sage, east coast of Australia, by Miss Archie McLean, while visiting the Great Barrier Reef in Australia. Loxostoma instabile Cushman and McCulloch, new species Plate 27, Figs. 15-17; Plate 28, Figs. 1-7 Test elongate, slender, especially in the earlier stages and in the micro- spheric form, cylindrical in the young, later becoming much compressed, periphery in the adult acute and keeled ; chambers distinct, in the micro- spheric form very gradually increasing in size as added in the early por- tion, later becoming rapidly larger and inflated in the median portion, compressed and keeled at the periphery, the posterior angles extending backward into distinct spines, later chambers becoming irregularly uni- serial; sutures distinct, in the later portion depressed, more strongly curved; wall mostly smooth, rather coarsely perforate, the perforations 222 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 often in longitudinal rows; aperture in the adult terminal, oval or ellipti- cal, with a marginal lip and a tubular internal structure connecting the aperture with the opening into the previous chamber. Length 0.65-1.10 mm.; breadth 0.25-0.30 mm. ; thickness 0.10 mm. Holotype (AHF no. 47) from Station 2070. This species differs from L. mayori (Cushman) in the much com- pressed adult portion, the keeled and spinose adult chambers, and the more conical early stage. There is a great amount of variation in this species as will be seen by our figures, the microspheric form often having the spinose and com- pressed chambers at the very end, while the megalospheric form has them reaching nearly to the base. From the localities this seems to have a rather restricted distribution. Stations: 56, 76, 82, 144, 215, 226, 227, 540, 1010, 1078, 2070. Type locality—Off Guadalupe Island, latitude 29° 8’; longitude 115° 10’, in 250 fms. Distribution —Off San Nicolas and Catalina islands in 147 fms.; off Guadalupe Island in 12 to 250 fms.; off Gorgona Island, Ecuador, in 20 fms. Loxostoma limbatum (H. B.

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 sometimes merges with the typical form, but the two seem rarely to occur together. Stations : 424, 500, 501, 503, 504, 2084. Distribution.—An analysis of the station records places this species off Socorro Island, Mexico, in 17 to 46 fms. and off La Libertad, Ecuador, in 4 to 25 fms.

Test elongate, slender, often arcuate or somewhat twisted, somewhat compressed, periphery rounded, the early portion somewhat tapering, later with the sides nearly parallel throughout their length; chambers nu- merous, distinct, becoming gradually higher as added until, in the later development, the height becomes greater than the breadth, and the last- formed chambers uniserial but usually with oblique sutures, and some- what more rounded in form than the early portion; sutures distinct, lim- bate, 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 lon- gitudinal lines, and surface with a few, short, weakly developed costae; aperture in the adult terminal, narrowly elliptical, often with a slight rounded lip. Length up to 2.00 mm.; breadth 0.30 mm.; thickness 0.20 mm. This is a widely distributed species in rather shallow tropical and subtropical regions. The specimens recorded here are somewhat variable NO. 4 CUSHMAN AND MCCULLOCH: SOME VIRGULININAE 225 and less well developed than is usual. ‘The specimens included from Aus- tralia may not belong here but have many similar characters. Stations: 76, 244, 295, 461, 466, 501, 616. Distribution —Off Guadalupe Island in 12 fms.; in the Gulf of California, Mexico, in 5 to 10 fms.; at Tagus Cove, Albemarle Island, in 80 fms.; off Charles Island in 23 fms.; off La Libertad, Ecuador, in 4 fms. ; and off the east coast of Australia at low tide. Genus BIFARINA Parker and Jones, 1872 Bifarina hancocki Cushman and McCulloch, new species Plate 28, Figs. 13-19 Test in the early stages compressed, biserial, in the adult uniserial and broadly elliptical in end view, periphery broadly rounded ; chambers dis- tinct, slightly inflated in the early stages, in the adult uniserial portion strongly inflated; sutures distinct, in the early biserial portion strongly limbate and raised, in the earliest portion strongly oblique, less so as growth progresses, in the adult uniserial portion, depressed ; wall distinct- ly perforate, in the early portion and in some specimens somewhat spinose throughout; aperture in the adult terminal, elliptical, with a distinct lip. Length 0.50-0.65 mm.; breadth 0.15-0.20 mm.; thickness 0.10-0.15 mm. Holotype (AHF no. 48) from Station 503. This species differs from B. zanzibarensis Cushman in the strongly raised and limbate sutures, more slender test, and spinose surface. There is considerable variation as shown in our figures. The surface is finely to coarsely spinose or in some specimens nearly smooth in the last- formed chambers. In the large series, however, these variations seem to merge and the whole represent a single species. Stations: 61, 256, 321, 331, 503, 514, 540, 543, 558, 583. Type locality—La Libertad, Ecuador, in 19 fms.

CUSHMAN AND IRENE McCuLiocu In this fifth paper presenting the results of studies being made on the foraminiferal collections of the Allan Hancock Foundation, The Uni- versity of Southern California, a fourth list of station tables is included. The station list of this paper covers additional records off southern California and is therefore a continuation of Table 7 (see pp. 11-13, 148-150, 180-183). Attention is called again to some inconsistencies in the Tables of this volume i.e., Stations 422-427 (see pp. 23-24) are not off the Galapagos Islands but off Mexico. The type locality and station number of holotype no. 53 in this paper emphasize this inconsistency. [231] VOL. 6 ALLAN HANCOCK PACIFIC EXPEDITIONS 232 61 ‘ZI 08 It6I ‘ax 9II os ie He He i.

Maximum length 0.55 mm; maximum breadth 0.30 mm. Holotype (AHF no. 53) from Station 422. The species differs from R. aculeata Cushman in the nearly straight sides, with little or no dentation, the initial end without a spine and the pores of the wall limited almost entirely to the border of the chamber. Stations: 63, 76, 221, 222, 244, 311, 422, 436, 457, 458, 470, 500, 504, 1026, 2004, 2011, 2015, 2019, 2020, 2039, 2067, 2081, 2082, 2084, ZIG 21268 21392153: Type locality—Socorro Island, Mexico in 16 fathoms. Distribution —These station records indicate a range from the Gulf of California, Mexico, southward to Ecuador with a number of localities in the Galapagos Islands. The depth range is from 3 to 80 fathoms. Genus CHRYSALIDINELLA Schubert, 1907 Chrysalidinella spectabilis Cushman and McCulloch, new species Plate 32, Figs. 1-7 Test elongate, early portion triserial and triangular in section, very soon becoming uniserial, the adult portion either triangular, quadrangu- lar or in some specimens compressed ; chambers distinct, increasing gradu- ally in breadth but very little in height in the adult uniserial portion; sutures distinct, slightly depressed in the adult; wall ornamented by longitudinal costae, those of each chamber distinct, the angles of the test in the adult often with very thin, transparent keels, the initial end some- times slightly spinose; apertures terminal, numerous, rounded, with thin, raised borders. Length up to 1.25 mm; diameter of triangular forms up to 0.55 mm; of broader compressed forms up to 0.65 mm. Holotype (AHF no. 54) from Station 2065. This species differs from C. dimorpha (H. B. Brady) in the orna- mented surface, more tapering test, and tendency toward a quadrangular or compressed shape. Our series of figures shows the range of variation in the adult stages of this species which is unique in this respect. No. 5 CUSHMAN AND MCCULLOCH: SOME BULIMINIDAE 257.

Type locality—Outer Gorda Bank, Lower California, Lat. 23° 01’ N.; Long. 109° 28’ W., in 50 fathoms. Distribution —With the exception of Station 542 which is off the coast of Ecuador in 65-80 fathoms, all other records of the above list indicate a wide distribution within the Gulf of California and off the coast of Mexico. The depth range is from 8 to 250 fathoms off Guada- lupe Island. Subfamily Uvigerininae’ The foraminifera included in this subfamily belong in the genera Uvigerina, Hopkinsina, Angulogerina, and Trifarina. The large series of specimens available for study has made more apparent than ever the close relationships between certain species and varieties, and the actual grada- tion of one species into another. Consequently, it must be recognized that the concepts of the species here presented may be a matter of convenience. More study of many more specimens may be expected to result in further clarification of this problem. The study of these large series of specimens also shows the wide range of ornamentation present, the variations in type of ornamentation and in degree, and the rudimentary ornamentation some- times present on a normally unornamented form. In some cases several specimens are figured illustrating these variations. In most species and varieties both microspheric and megalospheric forms have been recognized and in some cases figured to illustrate the great differences between them. A few species show gerontic characteristics, becoming smaller and more attenuated as growth proceeds. Genus UVIGERINA @’Orbigny, 1826 Uvigerina cushmani Todd, new species!

Test of medium size for the genus, elongate, of nearly equal diameter 1 The senior author of this report turned over all of the mounted material of the genera Uvigerina, Hopkinsina, Trifarina and of Angulogerina to Miss Ruth Todd, Research Associate, Cushman Laboratory for Foraminiferal Research. Miss Todd “has been responsible for the synonymy, description of new species, and the dis- cussion in connection with the species of these genera. 258 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 throughout, initial end bluntly pointed, slightly lobulated; chambers slightly inflated, of about equal size except the first-formed ones; sutures distinct, deeply incised, curved; wall thin, finely hispid, ornamented with numerous, low, narrow, rather widely spaced costae, and very fine spines, usually both being present, but sometimes only spines; aperture circular, at the end of a short neck, surrounded by a narrow, phialine lip. Length 0.60-0.80 mm; diameter 0.22-0.28 mm. Holotype (AHF no. 55) from Station 82, where it occurs abundantly. This species differs from U. senticosa Cushman in its slenderer form and the greater development of costae. It closely resembles U. juncea Cushman and Todd from the Pliocene of Timms Point, Calif., but differs in its larger, stouter test and more strongly developed ornamenta- tion. It also resembles U. pigmea d’Orbigny from the Pliocene of Italy but differs in its much less prominent costae. Specimens have been recorded from Pliocene? material from the Aleutian Islands. Specimens were found rarely to abundantly at numerous stations in the Hancock collections as follows: 73, 80, 82, 144, 517, 1041, 1068, 1070, 1074, 1082) 1096, 1101, 1110; 1118, 1122; 1125, 1127S 1135, 1143, 1144, 1146, 1147, 1148, 1157, 1158, 1159; 1162, 0163; 1164, 1165, 1168, 1174, 1176, 1179, 1180, 1181, 1182, 1184, 1186, 1190, 1196, 1198, 1199, 1200, 1201, 1203, 1204, 1205, 1218, 1219, 1223, 1224. 1225) (1226, 1227) 1228-1229: 1230; 1233, 1234s. 1239, 1242, 1244, 1245, 1246, 2014, 2087, 2107, 2110, 2154, 2162, 2169. Distribution.—The type locality, Station 82, is off Long Point, Cata- lina, in 147 fms. The stations listed thus far occur, on the whole, off the Channel Islands and in the Gulf of California at depths ranging from 10 to 212 fms.

Test large, elongate, compact, greatest breadth about middle of test, periphery lobulated; chambers distinct, inflated, rapidly increasing in size; sutures deeply incised, curved; wall thin, translucent, ornamented by numerous, low, regular, sharp, longitudinal costae, about 30 on the circumference of the test, not continuous across the sutures, occasionally No. 5 CUSHMAN AND MCCULLOCH: SOME BULIMINIDAE 259 becoming obsolete and spinous on the last-formed chamber; aperture large, at the end of a short, broad neck, surrounded by a narrow, flaring lip. Length 0.85-1.25 mm; diameter 0.35-0.50 mm. Holotype (AHF no. 56) from Station 55, where it occurs very abundantly. The unnamed species referred to in the reference above is from the Pliocene of Timms Point, California, and appears to be the same as this. This species differs from U. peregrina Cushman, var. curticosta (Cushman) and var. dirupta, n. var. in its lower, more regular, and much more numerous costae, and its more elongate shape. A very few specimens show a marked rugosity in addition to the costae, and may represent a varietal form, but they are not separated here. A single specimen from Station 1106, questionably referred here, is interesting as it possesses two complete apertures from the last- formed chamber. Such a freak development in this group of the for- aminifera has been noted previously. (See Uvigerina canariensis d’Or- bigny, var. distoma de Amicis [Atti Soc. Toscana Sci. Nat., vol. 14, 1894, p. 14, pl. 2, fig. 5] from the Pliocene of Sicily and Uvigerina angulosa Williamson of Heron-Allen and Earland, [Discovery Reports, vol. 4, 1932, p. 397, pl. 12, fig. 38] from Recent material from off the Falkland Islands.) In these cases the apertures were from two different chambers while in this case they are from the single, last-formed chamber. It is also found at the following stations: 56, 57, 58, 60, 64, 67, 230, 251, 299, 552, 1069, 1077, 1080, 1083, 1103, 1117, 1173, 1194, 1198, 2000, 2014, 2070, 2100, 2101, 2144, 2151, 2162. Distribution—The type locality, Station 55, is Los Islets, North Isla Partida, Mexico, bearing west, in 183 fms. An analysis of the other sta- tion records shows a range off the Channel Islands, in the Gulf of Cali- fornia southward to Callao, Peru, in 210 fms.

Length 0.50-1.00 mm; diameter 0.35-0.50 mm. This species, described from the Miocene of California, occurs at the following stations, usually rather rarely: 2, 39, 55, 1095, 1103, 1107, 1129, 1133. The specimens vary considerably in size and some are much larger than the types of U. hootsi, but they maintain their stout, inflated shape quite constantly. Distribution.—According to these records, the shallow water local- ities suggest a redeposition. Other stations show a depth range from 183 to 340 fms. Uvigerina incilis Todd, new species Plate 33, Fig. 4 Test small for the genus, slender, fusiform, initial end sharply pointed, the greatest diameter a little above the middle, periphery markedly indented ; chambers numerous, gradually increasing in size until the last one or two, then decreasing, the last-formed ones tending to become biserial ; sutures very distinct, straight, deeply incised ; wall thin, translucent, ornamented with numerous, sharp costae, not continuous across the sutures, usually regular, but sometimes serrate and spinous; aperture small, circular, at the end of a short neck, surrounded by a flaring lip. Length 0.48-0.55 mm; diameter 0.20-0.25 mm. Holotype (AHF no. 57) from Station 217. This species differs from U. subperegrina Cushman and Kleinpell in its deeply incised sutures and its smaller, slenderer form. This species occurs rarely to frequently at the following stations: 200, 201, 215, 217, 336, 343,422. 503, 505,; 509; 539,542; 543, Ssemoue 583, 2016, 2087, 2090, 2093, 2094, 2113, 2132, 2134, 2136, 2137, 2140, 2146, 2149, 2152, 2153, 2154, 2164, 2165. Distribution—The type locality, Station 217, is Tenacatita Bay, Mexico, in 50 fms. Other records are off Mexico, off Central America, and off the coasts of Colombia and Ecuador in 6 to 138 fms. No. 5 CUSHMAN AND MCCULLOCH: SOME BULIMINIDAE 261 Uvigerina kernensis Barbat and von Estorff? Plate 33, Fig. 5 Test short and stout, greatest diameter toward apertural end; cham- bers inflated, rapidly increasing in size as added; sutures distinct, deeply depressed; wall ornamented by a few, low, somewhat irregular costae becoming obsolete toward the apertural end; aperture at the end of a short neck, without a lip so far as observed. Length 0.45-0.90 mm; diameter 0.33-0.45 mm. No types of U. kernensis Barbat and von Estorff (Journ. Pal., vol. 7, 1933, p. 172, pl. 23, fig. 13) which was described from the Miocene of California, have been available for comparison, and these specimens are referred here questionably. In general shape they resemble “Uvigerina canariensis d’Orbigny, var. striata Bagg’’ but the ornamentation is much stronger than on the type of that form, with which these have been com- pared. Specimens occur commonly at Station 1 and rarely at Stations 1236 and 2144. Distribution—An analysis of these three station records places this species off San Pedro in 12 fms, off Long Point, Catalina Island, Cali- fornia, in 300 fms, and in the Gulf of California in 113 to 117 fms.

Test of medium size, elongate, compact, periphery only slightly in- dented ; chambers large, early ones indistinct, not inflated, the last one or two chambers smaller than previous ones; sutures indistinct in the early part, deeply incised between later chambers, not curved; wall orna- mented by numerous, low, sharp costae, about 20 on the circumference of the test, aligned across the sutures, although interrupted by the more deeply incised sutures, tending to disappear on the last-formed chamber; aperture circular, at the end of a short neck, surrounded by a thickened rim. Length 0.60-0.65 mm; diameter 0.25-0.30 mm. This species, based on Soldani’s figures, was described from the Adri- atic, and has not been recorded elsewhere. Distribution—A number of specimens which appear to belong here ‘were found in the Hancock material from Gibraltar (Station 648) and a single specimen from Port Said (Station 634). 262 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 EXPLANATION OF PLATE 31 FIcs. 1.

Variety differing from the typical form in the smaller, slenderer form, the fewer and much lower costae, and the more finely punctate, translucent, wall. Length 0.50-0.60 mm; diameter 0.25-0.30 mm. This, as well as the other varieties, shows a considerable range of ornamentation with costae, serrate costae, and spines. This variety was described from off the northeastern coast of the United States and has been recorded from late Tertiary core material off the Atlantic coast, from the Pliocene of California, and from the Pacific. The specimens have been compared with typical specimens from the Atlantic and seem to be the same, although generally smaller. They are from stations: Or. 10, 82, 667, 1097, 1105, 1106, 1135, 1150, 1178. Distribution.—The station records here include, off the coast of Ore- gon, off California and in the harbor of Port Said in 13 to 175 fms. Uvigerina peregrina Cushman, var. curticosta (Cushman) Plate 34, Fig. 2 Uvigerina pigmea d’Orbigny, var. curticosta Cushman, Bull. Scripps Instit. Oceanography, Tech. Ser., vol. 1, No. 10, 1927, p. 157, pl. 4, fig. 1—Cushman and Moyer, Contr. Cushman Lab. Foram. Res., vol. 6, 1930, p. 60. Variety differing from the typical form in the fewer costae, more irregularly spaced, not usually aligned from chamber to chamber, some- times slightly oblique to the axis of the test, lacking any spinosity. Length 0.50-1.00 mm; diameter 0.25-0.50 mm. This form was described from 800 fathoms, off Panama (Lydonia Sta. 33), as a variety of U. pigmea d’Orbigny. It seems, however, to be much more closely related to U. peregrina Cushman from off the eastern United States and is here placed under that species. It has a great range in size but maintains its ornamentation of high, discontinuous, rather widely spaced costae. No. 5 CUSHMAN AND MCCULLOCH: SOME BULIMINIDAE 267 This variety occurs widely and usually abundantly at the following stations: C-15, 1080, 1095, 1103, 1105, 1107, 1124, 1168, 1178, 1207, PALO MI2It. 1212, 1226, 1243, 2070: Distribution —With the exception of Station 2070, off Guadalupe Island in 250 fms, all other records here are off the coast of California, and off the Channel Islands from low tide to 600 fms. Uvigerina peregrina Cushman, var. dirupta Todd, new variety Plate 34, Fig. 3 Variety differing from the typical form in the larger size and in the ornamentation, the costae becoming strongly serrate, and, toward the apertural end, breaking up into spines. Length 0.85-1.15 mm; diameter 0.45-0.55 mm. Holotype of variety (AHF no. 58) from Station 1212. The ornamentation shows all degrees of spinosity from an almost lack of spines to a completely spinose form without any trace of alignment of spines. Where there is a combination of spines and costae the spines are best developed toward the apertural end. Brady’s reference to an unnamed Uvigerina from off Juan Fernandez (Rep. Voy. Challenger, Zoology, vol. 9, 1884, pl. 74, fig. 26 [not figs. 24, 25]) may be this variety. The variety is fairly common at Stations 1211 and 1212 and single specimens were found at 1095 and 1210. Distribution.—The type locality, Station 1212, is 8 miles north of Long Point, Catalina Island in 490 fms. All other records are in the im- mediate region of this island with the exception of 1095, off Redondo Beach, California, in 240 fms.

Length up to 0.85 mm; diameter 0.25-0.42 mm. This species was described from the Pliocene of Kar Nicobar and is also known from other localities in the Indo-Pacific, fossil and Recent, and from the Pliocene of California and the Miocene of Buff Bay, Jamaica. This species was recorded at stations: 513, 1105, 1122, 1150. Specimens from the last station are larger than those from the first three. Distribution.—These station records place this species off Catalina Island, off Seal Beach, California, in 47 to 225 fms, and off the coast of Colombia in 47 fms.

Very rare, usually single, specimens from a few stations may be re- ferred with some question to this variety which is distinguished from the typical form by its smaller size and slender form, and the elongate apertural neck. The present specimens, however, have more inflated and globose chambers and the neck is not as long as in the types. Also, the hispid wall shows an alignment, occasionally developing into faint longi- tudinal costae at the initial end. ‘The specimens are from the following stations: 82, 629, 637, 655, 664, 1182, 1184, 1218, 1229, 1243, 2164. The known distribution of this variety is Recent of the Tropical Pacific and Miocene of Jamaica. Distribution —These stations include records off Catalina, San Clem- ente, and Cedros Islands in 46 to 228 fms, and from the harbors of Singapore, of Kobe, Japan, and Colombo Bay in 7 to 90 fms.

Length up to 0.85 mm.” The bristly ornamentation occasionally develops into actual fine spines on the initial portion of the test and may be longitudinally aligned. Our specimens are generally smaller but some tend to be more robust than the types. Several are figured to illustrate the variations. The original description is quoted above. This species was described from 1390 fathoms, off southern California (Guide Sta. 3). It occurs in typical form but never abundantly at a number of stations as follows: A-1, Or. 9, Or. 10, 1, 58, 80, 82, 136, 144, 230, 1074, 1078, 1079, 1100, MOG MG iti. MOS ZO 2s 1132.

Length 0.60-0.70 mm; diameter 0.30-0.40 mm.” The original description is quoted above, of this species from the Miocene of California. A number of specimens from the following sta- tions: 1, 2.57, 227, 509, 11077, 11081, 1123; 1125; 1146, 90h Zs 1226, 2155, may be referred here, making the first Recent records for this species. ‘These Recent specimens differ somewhat, chiefly in being proportionately slenderer. Distribution —The records here off San Pedro, and the Channel Islands, indicate a depth range of 12 to 170 fms; off Guadalupe and San Benito Islands, 35 to 200 fms; and 17 to 25 fms in San Jose Del Cabo Bay.

No. 5 CUSHMAN AND MCCULLOCH: SOME BULIMINIDAE 271 Length 0.40-0.50 mm; breadth 0.17-0.20 mm; thickness 0.12-0.15 mm. This species, described from the Pliocene of Italy, is present at the following stations: 634, 636, 648, all in the Mediterranean Sea. The present specimens show the gradation of this form into Siphogenerina. Distribution—The bottom samples were collected at Port Said, Naples and Gibraltar in 7 to 90 fms. Uvigerina sp. A Plate 34, Fig. 8 Test small, fusiform, greatest breadth a little above the middle; chambers distinct, inflated, rapidly increasing in size so that the last two whorls comprise most of test ; sutures deeply incised, curved ; wall smooth, polished, sometimes with faint traces of costae at the base of the later chambers; aperture at the end of a short, stout neck, surrounded by a phialine lip. Length 0.40-0.47 mm; diameter 0.18-0.20 mm. This species differs from U. canariensis d’Orbigny in the chambers less rapidly increasing in size so that the last whorl makes up proportion- ately much less of the test than it does in U. canariensis; in the faint costae; and in its smaller size. Four specimens of this species were found at Station 200. Distribution —Tangola Tangola, Mexico. Uvigerina sp. B Plate 34, Fig. 9 Test short and stout, chambers few, large, inflated; sutures deep; wall thin, translucent, ornamented by fine, sharp, rather widely spaced spines with the addition in some specimens of a few serrate costae on the early portion of the test; aperture at the end of a prominent neck with a narrow lip. Length 0.50-0.55 mm; diameter 0.35-0.42 mm. This species seems to be undescribed. It occurs at only two stations: 1150 and 1243, and with too few specimens available for adequate de- scription. Distribution—These stations are Point Dume in 47 fms and off Long Point, Catalina Island in 228 fms. Bie ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 EXPLANATION OF PLATE 33 Fics. 1.

Length 0.37-0.52 mm; diameter (including costae) 0.20-0.27 mm. Holotype (AHF no. 59) from Station 416, where it is common and beautifully preserved. This species somewhat resembles Uvigerina porrecta H. B. Brady from the Indo-Pacific region but the chambers are globose rather than angular, and the costae are fewer and much higher and sharper. The species is placed in the genus Hopkinsina as it becomes biserial in the adult. : It also occurs less commonly and in less typical form at the following additional stations: Lowe 1, 200, 409, 511, 512, 513, 583, 1122. Distribution —The type locality, Station 416, is north of Duncan Island, Galapagos Islands, in 35 to 68 fms. With the exception of Station 1122, off Catalina Island, in 208 fms, the other records are off Central America, off the Galapagos Islands, and off the coast of Ecuador. Hopkinsina oceanica Todd, new species Plate 35, Fig. 2 Test fusiform, attenuated, initial end pointed, periphery lobulated; chambers distinct, strongly inflated, rapidly increasing in size as added until the last two or three, the last several pairs of chambers biserially arranged; sutures distinct, deep, not curved; wall thin, ornamented by a combination of high, sharp, serrate costae and coarse, sharp, thickly set spines; aperture circular, at the end of a prominent neck, surrounded by a fragile lip. Length 0.42-0.52 mm; breadth 0.22-0.25 mm; thickness 0.17- 0.20 mm. Holotype (AHF no. 60) from Station 513. No. 5 CUSHMAN AND MCCULLOCH: SOME BULIMINIDAE 217 This species differs from H. hancocki, new species, in having its last few chambers reduced in size and in its almost complete covering of orna- mentation. It is common here and shows its considerable range of variation in ornamentation. It occurs less frequently at the following additional sta- tions: 112, 503, 505, 512, 540, 583, 1096. Distribution.—The type locality is Station 513, off the coast of Co- lombia, 0° 39’ 20” N., 80° 15’ 30” W. in 58 fms. Other records include the coast off Redondo Beach, Catalina Island, the coast of Colombia, and off the coast of Ecuador. Genus ANGULOGERINA Cushman, 1927 Angulogerina albatrossi Cushman Plate 35, Fig. 3 Angulogerina albatrossi Cushman, Contr. Cushman Lab. Foram. Res., vol. 8, 1932, p. 45,’ pl. 6, figs. 11, 12. Test elongate, subfusiform and irregularly triangular throughout in the microspheric form, subcylindrical and irregularly inflated in the megalospheric form, becoming loosely coiled toward the apertural end; chambers few, slightly inflated, those of the microspheric form and the last-formed ones of the megalospheric form triangular in section, some- times with concave sides; sutures distinct, deeply depressed ; wall coarsely punctate, generally smooth, although on the microspheric form the early part sometimes shows traces of low costae and the initial end may have very slight spinose projections; aperture large, at the end of a distinct neck, surrounded by a thickened phialine lip. Length 0.90-1.25 mm; diameter 0.30-0.60 mm. The megalospheric forms are identical with the types which were from Albatross H 1805, off the west coast of Mexico, Lat. 18° 33’ 30” N., Long. 114° 44’ 00” W., 1732 fms. Microspheric forms have not been figured previously and are quite different in shape, being much broader in the middle of the test, and having a pointed rather than rounded initial end. Three specimens are illustrated to show these varia- tions. Only the microspheric forms, as would be expected, show faint traces of ornamentation and seem almost to grade into the var. ornata. A few specimens from the following stations: 223, 420, 432, 438, 444, 461, 474, 1189, 2084, are placed in this species. Distribution —Analysis of these station records shows a range from -Cortes Bank in 51 fms southward to Hood Island in 175 fms. 278 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 Angulogerina albatrossi Cushman, var. hirsuta Todd, new variety Plate 35, Fig. 4 Variety differing from the typical form in the ornamentation, consist- ing of numerous high, sharp costae on the early part of the test, and prominent, thickly-set spines over the later two or three chambers and even the apertural neck, and in the proportionately stouter and more sharply triangular, but not carinate, section of the test. Holotype (AHF no. 61) from Station 406, off the Galapagos Islands. This variety exhibits great variation in size from one locality to another. The specimens from Station 406 are fairly uniform: 1.00-1.25 mm in length and 0.50-0.55 mm in breadth. Those from the other sta- tions: 5, 403, 412, and 473, are much smaller: 0.60-0.80 mm in length and 0.25-0.40 mm in breadth. In addition, the proportion of costae and spines varies greatly, and sometimes the initial end also bears spines. From the material available it seems related to 4. albatrossi, especially the microspheric form of that species, but it may prove to be a distinct species. Distribution.—The type locality is 1° 03’ 30” S., 90° 17’ 30” W. in 60 fms. Additional records include one off San Pedro in 38 fms, and four off the Galapagos Islands at depths from 9 to 111 fms.

Variety differing from the typical form in the ornamentation, consist- ing of very fine costae, low, yet sharp, slightly wavy in pattern, curving, branching, and intercalating, not continuous across the sutures, and usu- ally faint or absent on the last-formed chamber. The strength of the ornamentation varies considerably, the costae being almost obliterated on some specimens, yet with the characteristic wavy pattern still visible. ‘This variety shows the same sort of variation in shape of test in the microspheric and megalospheric forms as that shown by the species. Two specimens are figured to illustrate this. A. albatrossi var. ornata Cushman was described from the same sta- tion as the species off the west coast of Mexico, and has been recorded as rare from the Tropical Pacific. It occurs in few numbers with the typical form at two of its stations, 223 and 2084, and at the following additional No. 5 CUSHMAN AND MCCULLOCH: SOME BULIMINIDAE 279 stations: 283, 403, 409, 411, 412, 414, 419, 423, 427, 460, 472, 473, 2081, 2086, 2129.

They may be merely stages or micro- and megalospheric forms of a single species; 4. baggi being the early stage or the megalo- spheric form, and 4. hughesi the adult stage or microspheric form. The separation between the two seems to be arbitrary and is based on shape of test (short, fusiform, and periphery not lobulated in baggi) and sutures (not depressed in baggi). Distribution.—With the exception of one record off Isla Partida, Mexico, in 140 fms, the other localities are off the Channel Islands in 12 to 160 fms.

Length up to 0.90 mm.” The original description of 4. carinata Cushman, quoted above, ac- curately describes a large number of specimens from the following sta- tions: 35, 55, 56, 57, 60, 64, 80, 82, 223, 230, 242, 250, 284, 299, 517, 1055, 1069; 1077, 1078,' 1081, 1082, 1101, 1103, 1110; ides siiaiss 1120,- 1124, 1130, 1137;:4141, 1146, 1157, 1168, 1173. Pipers 1180, 1182, 1183, 1196;: 1198, 1199, 1200, 1201, 1205, 1225isi24ae 1244, 2000, 2009, 2070, 2079, 2084, 2097, 2098, 2100, 2101, 2106, 2107, 2144, 2151, 2152, 2158, 2161, 2162, 2163. It occurs very abun- dantly at stations: 55, 56, 60, 64, 1147, 2101, 2158. The species was described from Guwide Station 12, Lat. 32° 28’ N., Long. 118° 20’ W., 429 fms, and has been recorded from other Pacific localities and from the Pliocene, Charco Azul formation, of Panama. This species is very distinctive in the white, opaque shell well. The radial tubules in the-carinae of the test are not always present. As noted in the original description, the species attains a large size. he largest observed in the present collection are 1.90 mm in length and 0.70 mm in breadth, from Station 2014. In some specimens there is a tendency toward a few large, low costae on the early part of the test and sometimes the carinae are broken into projecting spines at the initial end of the test. In these characters the spe- cies approaches var. vana, n. var. In the large collection available, another direction of variation has been noted: toward a more slender, somewhat twisted form with less prominent and blunt carinae. A specimen is figured but the available material is too meager to warrant description as a new variety, figure 11. Specimens occur at stations: 2000, 2009, 2014, 2100, 2101, 2151. This species is easily distinguished from 4. albatrosst Cushman, with which it occurs, by its carinae which are continuous from initial to aper- tural end, and by its much more regular form with nearly horizontal sutures. Distribution.—These stations are off Catalina Island and southward to the coast of Colombia in 116 fms, including many localities in the Gulf of California. The depth range recorded here is 6 to 250 fms.

Variety differing from the typical form in the ornamentation of the chambers consisting of numerous, low, longitudinal costae, not continu- ous across the sutures, and usually lacking on the last-formed chamber or two. From the type specimens of this variety one would judge it to be a more slender, delicate, and thinner-walled form than the species. The present large collection available, however, shows it to be quite as robust and heavy as the unornamented species. But, like the species, it also exhibits considerable variation in size and shape of test as well as in degree of ornamentation. This species was described from Albatross H 1805, off the west coast of Mexico, Lat. 18° 33’ 30” N., Long. 114° 44” 00” W., 1732 fms. Typical specimens occur at the following stations: 242, 284, 299, 412, 7 1078) 1100, 1112, 1147, 1186, 1190, 1194, 1198,-1207, 1221, 2005; 2009, 2010, 2063, 2064, 2065, 2097, 2100, 2102, 2140, 2145, 2149, 2158, 2163. Distribution—All of these stations are off the Channel Islands and in the Gulf of California in depths from 2 to 600 fms. Angulogerina carinata Cushman, var. vana Todd, new variety Plate 35, Fig. 10 Variety differing from the typical form in the ornamentation; the carinae being thin and broad, sharp, and undulating or spinose, and the walls of the early chambers covered by a few, heavy, short, irregular costae or more thickly covered by finer, higher costae, often with back- wardly-projecting spines. In size and shape of test and opaque wall the variety closely resembles the typical form. Holotype (AHF no. 63) from Station 1103. It also occurs at the following stations: 227, 230, 284, 1083, 1095, 1103, 1116, 1117, 1168, 1178, 1212, 1222, 1244, 2070, 2144, 2161. 288 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 Distribution.—The type locality is 314 miles east of Long Point, Catalina Island, 285 fms. With the exception of one record in the Gulf of California, these localities are off Catalina, Guadalupe and San Benito Islands in depths ranging from 47 to 490 fms. Angulogerina agrestis Todd, new species Plate 36, Fig. 6 Test very small for the genus, irregular, compactly coiled in the early part, becoming attenuated toward the apertural end, periphery indented, greatest width usually below the middle; chambers indistinct, overhanging, last chamber usually concave on its inner face; sutures deeply depressed; wall covered by numerous, high, serrated costae and spines giving a rugose appearance to the test; aperture large, at the end of a prominent neck, surrounded by a phialine lip. Length 0.40-0.62 mm; breadth 0.20-0.25 mm. This species differs from 4. albatrossi Cushman, var. hirsuta n. var. in its much smaller size and slenderer and more attenuated shape. In type of ornamentation the two forms are quite similar. Holotype (AHF no. 62) from Station 73, where it occurs abundant- ly. It occurs frequently to rarely at the following additional stations : 207, 223, 226, 628, 1062, 1064, 1072, 1113, 1120, 1138, 1140, 1151, 1183, 1184, 1186, 1188, 1189, 1192, 1193, 1194, 1195, 1225, 1228, 1242, 2070, 2081, 2084, 2098. Distribution.—Type locality, Station 73, is off Guadalupe Island in 17 fms. Other localities are north of Santa Barbara Island in 40 fms; and southward to Socorro Island in 17 to 46 fms. There is also one record for Manila Harbor, Philippines. Angulogerina fluens Todd, new species Plate 36, Fig. 1 Angulogerina fluens Todd, Ms, in Cushman and Todd, Contr. Cush- man Lab. Foram. Res., vol. 23, 1947, p. 67, pl. 16, figs. 6, 7. Test elongate, slender, fusiform, triangular in section in the early part, later becoming irregularly inflated, and finally sometimes with flattened chamber walls and strongly indented periphery, greatest breadth about the middle of the test, periphery lobulated ; chambers compact and indistinct in the early part, rapidly increasing in size, inflated in the later part, sometimes the last several chambers smaller and remotely placed, with flattened or concave walls; sutures distinct, depressed, strongly curved; wall ornamented by numerous, low costae, curving with the No. 5 CUSHMAN AND MCCULLOCH: SOME BULIMINIDAE 289 curvature of the chambers, often confluent across the sutures; aperture terminal, elongate oval, without a neck or with only a short one, sur- rounded by a slightly thickened rim. Length 0.45-0.65 mm; width 0.20-0.30 mm. This species seems to be characterized by its curved costae, sometimes confluent across the sutures, and its compressed aperture. It may be dis- tinguished from A. angulosa (Williamson) by its more heavily orna- mented test and its later inflated and irregular chambers, whereas 4. angulosa is triangular in section throughout. It may be mentioned, how- ever, that rare specimens of 4. fluens n. sp. are also triangular throughout, and these are believed to represent microspheric individuals. One of these is figured. The occasional development of the attenuated, flattened or concave, later chambers is believed to represent the gerontic stage of development of this species, and a specimen is figured illustrating this stage (See figs. 1d, e and f.) Some of the specimens figured as “Uvigerina angulosa Williamson” by Heron-Allen and Earland (Discovery Reports, vol. 4, 1932, p. 397, pl. 12, figs. 33-36 [not 32, 37-39]) from off the Falkland Islands would appear to belong in this species. The species has been recorded from Pliocene? material from the Aleutian Islands. Holotype (AHF no. 64) from Station A-2, at Wrangell, Alaska, where it occurs abundantly. It also occurs at the following stations: A-1, 67, 226, 228, 283, 285, 535, 1100, 1168, 1183, 1201, 1204, 2063, 2086, 2097, 2098, 2100, 2131, 2140, 2149, 2152, 2153, 2154, 2156, 2165, 2167. It is especially beautifully developed at Station 535, Lobos de Afuera Island, Peru, from which station a specimen is illustrated (figures 1d, e). Distribution —The type locality, Station A-2, is Wrangell, Alaska, in 2 fms. A further analysis of the localities places this species off Peru in 22 fms and in the Gulf of California in depths ranging from 8 to 160 fms.

The original description of this species from the Pleistocene is quoted above. The species occurs commonly to rarely at numerous stations as follows: 227, 230, 284, 1083, 1095, 1113, 1116, 1117, 1168, 1178, 1212, 1222, 1244, 2070, 2144, 2161. Distribution—TJwo areas are represented in these station records, off San Pedro, San Benito, and Guadalupe Islands, and in the Gulf of California in depths of 17 to 490 fms. Angulogerina hughesi (Galloway and Wissler), var. picta Todd, new variety Plate 36, Fig. 3 Variety differing from the typical form in the ornamentation consist- ing of costae and spines, the costae low, numerous, and faint, sometimes extending over nearly the entire test but more prominent toward the initial end, and the spines short and heavy and varying from covering the lower half of the test to almost none. The ornamentation on this variety is a highly variable character but the spinosity is consistently toward the initial, not apertural, end. The sizes and shapes of the tests include forms that, lacking ornamentation, would be included in both 4. hughesi and A. baggi, thus suggesting that these two species should be combined. Holotype (AHF no. 65) from Station 1194. This variety is very widespread, more so than the typical form of the species.

Test elongate, slender, occurring in two forms: one compact, fusi- form, and with the periphery nearly smooth, the other longer, attenuated, of about equal width throughout, and with greatly indented periphery; chambers compact and indistinct in the early part, slightly inflated, later becoming remote, with flat or concave faces, not increasing in size except the earliest ones; sutures distinct, strongly depressed; wall thin, orna- mented with numerous, weak, low, longitudinal costae, usually absent over the later chambers, sometimes heavy and spinous at the initial end, not continuous across the sutures except over the earlier chambers; aper- ture relatively large, at the end of a very short neck, surrounded by a very narrow lip. Length 0.40-0.75 mm; width 0.17-0.22 mm. 292 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 This species was described from the Dry Tortugas, off Florida, and has been very widely recorded, both Recent and fossil (Pliocene and Miocene). Our specimens have been compared with the types and some are considerably larger, but nevertheless would seem to belong here. These specimens strongly resemble 4. byramensis (Cushman) from the Oligocene of Mississippi, especially in showing the two forms, one smoothly fusiform and the other greatly indented. That species, however, is more heavily costate throughout. They are from the following stations: Or. 7, Or. 10, 73, 76, 80, 82, 83-101, 109) 113; 114, 133/135, 144) 207, 222, 223. 225,226,227 241, 298, 313, 409, 410, 422, 423, 447, 458, 460, 465, 470, 472, 542, 653, 1017, 1063, 1066, 1068, 1073, 1083, 1086, 1095, 1096, 1097, 1099, 1101, 1102, 1105, 1106;; 1110; 1192, 1114; 1116; 1118, TitoRees 1126, 1127; 1132, 1135,/1136/'1137, 1138, 1143, 1150) Pis7 aise 1159, 1160; 1167, 1168)\ 1173,..1175, 1182, 1186, 1190; 1192 Seni: 1196, 1199, 1201, 1203,'1205,, 1206, 1218, 1219, 1220, 1Z21Ri225s 1224, 1225, 1226, 1228, 1229; 1230, 1232, 1234, 1236, 1245, 1246; 2066, 2070, 2081, 2082, 2084, 2086, 2087, 2098, 2130, 2139, 2141, 2142, 2145, 2153, 2154, 2155, 2156, 2157.

No. 5 CUSHMAN AND MCCULLOCH: SOME BULIMINIDAE 293 “Tength of the type specimen, 0.43 mm; diameter, 0.25 mm.” The original description is quoted above. This species was described from the Pleistocene of California and has been recorded from the Pliocene and also from Recent material off California and Washington. The specimens average a little smaller than the types and the strength of ornamentation varies considerably. Also, more elongate forms are in- cluded than the type figure would indicate, but this is known to be true from a study of typical specimens from the Pliocene of California. This is one of the baggi-hughesi-semitrigona group and, again, the separation seems to be arbitrary; forms which are tricarinate toward the apertural end and more or less completely costate being placed here. The separation between 4. semitrigona and A. hughest, var. picta, n. var., is mainly on the basis of the ornamentation, that in var. picta being more strongly developed toward the initial end and including spines. Numerous specimens from a large number of stations are referred to this species: Or. 8, 1, 60, 73, 76, 80, 82, 83, 106, 109, 111, 113, 114, 203, 222, 225, 232, 248, 249, 256, 271, 286, 299, 409, 412, 414, 417, 423, 466, 469, 471, 472, 652, 653, 666, 1017, 1062, 1063, 1068, 1070, 1072, 1073, 1075, 1096, 1097, 1098, 1102, 1104, 1111, 1112, 1114, PUGS F119.

SOME LAGENIDAE IN THE COLLECTIONS OF THE ALLAN HANCOCK FOUNDATION Joseph A. Cushman and Irene McCulloch The foraminifera included in this paper belong in the family Lagenidae. This is one of the most difficult families in the foraminifera, in respect to applying specific names, as the amount of variation is very great. Also, it is difficult to try to give the synonymy for various species as so many authors have placed such a wide variety of forms under the same name and many of the records are without figures. We have tried to show some of the variations on our plates. Many of the forms previously referred to Lagena belong in the genus Entosolenia which will be taken up at a later time. For ease in finding the various species of Lagena, they have been arranged alphabetically. Family Lagenidae Subfamily Nodosariinae Genus ROBULUS Montfort, 1808 Robulus strongi Church Plate 37, Figs. 1, 2 Robulus strongi Church, Journ.

This is a large species described from 30-40 fathoms, off White’s Landing, Santa Catalina Island, California, and recorded from the Pleistocene of Timms Point, California. A few of the specimens have a tendency to a twisting of the axis as in Darbyella. The specimens very closely resemble Robulus occidentalis (Cushman), var. novangliae (Cush- man) from the colder waters of the Atlantic Coast. Some of the Pacific Coast specimens are large, measuring up to 5 mm. in diameter.

Distribution.—Stations 80 through 1244 off San Pedro and the Channel Islands place this species at a depth range of 26 to 230 fms. off Santa Rosa Island with an average of 68 fms. Stations off Mexico give a range of 7 to 250 fms. with an average of 90 fms. At Panama, the depth was 54 fms. In the Galapagos Islands, 28 to 68 fms. with an average of 64 fms. The hauls off Guadalupe and Duncan Islands showed the largest numbers. Robulus cf. cultratus Montfort, var. Plate 37, Figs. 5-8; Plate 38, Figs. 1-3 The figured specimens show a considerable amount of variation and would be placed under this species by numerous authors from a study of their figures. There are many intermediate forms which make this group a very confusing one. Stations: 82, 1055, 1069, 1079, 1083, 1101, 1103, 1105, 1117, 1169, 1177, 1195, 1198, and 1212. Distribution —Off the Channel Islands with depth range of 45 to 285 fms. The average depth is 182 fms. Some of the best material was off Seal Beach in 225 fms. Robulus orbicularis (d’Orbigny) Plate 38, Figs. 4-7 Numerous forms have been referred to this species from widely sepa- rated areas. The series here figured seems to come within the range of variations of this species. As so many forms have been referred to this species, no attempt is made to give a synonymy here.

Fermin in 18 fms. and off Catalina in 600 fms. Stations 406 to 488 are located in the Galapagos Islands with a depth range of 35-111 fms. The average is 90 fms. Three stations off Colombia, South America, 553-587, have an average depth of 62 fms. One record at Port of Spain shows a depth of 45 fms. The best specimens came from off Colombia and the Galapagos Islands. Dentalina cf. calomorpha (Reuss) Plate 41, Fig. 6 Rare specimens similar to that figured may be referred to this species with some question. Stations: A-2, 1006, 1068, 1231, 265, 2017, and 514. Distribution.— Station A-2 is Wrangell, Alaska in 2 fms. Stations 1006, 1068, and 1231 are San Nicolas, San Miguel and Santa Rosa Islands in 63, 39, and 45 fms. respectively. Stations 265 and 2017 are in the Gulf of California with 16 and 20 fms. Station 514, off Colombia, South America, is 16 fms. The number was greater at Wrangell, Alaska, than elsewhere.

Brady Plate 41, Fig. 19 Very rare specimens in the Hancock collection have the peculiar orna- mentation as in the specimen here figured. It somewhat suggests Brady’s species although in our specimen the interrupted costae continue through- out the test instead of on the later chambers only. Station: 634. Distribution.—Station 634 consists of a bottom sample collected in the Harbor at Port Said, no depth given but it was presumably very shallow water, possibly from the anchor of “World Liner.” Nodosaria cf. perversa Schwager Plate 41, Figs. 26-32 The series of figured specimens gives an idea of the variation in this form which is referred with some question to Schwager’s species. More than one species may be represented but there are intermediate forms which seem to interrelate the whole series.

Test elongate, very slightly tapering, initial end with a distinct spine; chambers increasing very slightly in size as added in the megalospheric form, somewhat inflated; sutures distinct, slightly depressed, nearly straight ; wall with numerous fine longitudinal costae independent of the sutures ; aperture terminal, radiate. This is a variable species but the specimen figured seems to come within the limits of the species. Station: 1107. Distribution.—The single station record in relatively shallow waters off Long Point, Catalina Island, suggests the need to seek much addi- tional material for further study for its occurrence in Eastern Pacific waters. Nodosaria subscalaris Cushman Plate 41, Figs. 21-24 Nodosaria subscalaris Cushman, Proc. U.S. Nat. Mus., vol. 51, 1917, p. 654; Bull. 100, U. S. Nat. Mus., vol. 4, 1921, p. 201, pl. 36, fig. 2. The series of specimens here figured shows the considerable varia- tion in this species which is referred to N. subscalaris described from the western Pacific. While most of the characters are similar, the aperture in our specimens has a distinct neck and lip with transverse costae instead of longitudinal ones. The species is very common in the Hancock ma- terial.

Plate 41, Fig. 25 Very rare specimens of the form figured occur in the Hancock collec- tion but more specimens are needed to give a specific name definitely. Station: 2070. Distribution.—Station 2070, off Guadalupe Island in 250 fms., has been one of the most interesting of all the bottom samples studied thus far. No. 6 CUSHMAN, MCCULLOCH : LAGENIDAE 325 Genus PPEUDOGLANDULINA Cushman, 1929 Pseudoglandulina laevigata (d’Orbigny) Plate 42, Fig. 4 Specimens from several stations are of the form here figured and may be referred to d’Orbigny’s species. So many forms have been referred to this species, especially without figures, that it is impossible to give a complete synonymy. Stations: 1130, 1150, 212, 603, 604, 606, 622, 640, 644, 654, and 658.

Our figures show various stages of development. Station: 52. Distribution.—The single station record for this species in the Han- cock collections was a sample collected at Conway Bay, Indefatigable Island in 1932, at low tide. Genus SARACENARIA Defrance, 1824 Saracenaria angularis Natland Plate 42, Figs. 8-12 Saracenaria angularis Natland, Bull. Scripps Instit. Oceanography, Tech. Ser., vol. 3, No. 10, 1933, table; vol. 4, No. 5, 1938, p. 143, pl. 5, figs. 1, 2. “Test elongate, chambers rapidly increasing in size, triangular in cross section, margins carinate, with a wide keel of clear shell material ; sutures distinct, depressed slightly, obliquely set; walls smooth, thin, almost translucent; aperture radiate, at the apex of the chamber. Length 0.77 mm.; breadth 0.55 mm.; thickness 0.55 mm.” The types of this species are from off the southern coast of California. It has probably been referred to as “S. italica Defrance” in records from the upper Pliocene and Pleistocene of the Los Angeles Basin. It is very common and typical in our present material.

Plate 42, Fig. 13 Very rare specimens from Station 222, 4-10 fms., in small bay west of Braithwaite Bay, Socorro Island, Mexico, and Station 223, 53 fms., Sulphur Bay, Clarion Island, Mexico, show a more elongate form than the preceding but not enough specimens are available to place it specifically. Stations: 222 and 223. Genus VAGINULINA d’Orbigny, 1826 Vaginulina exilis Cushman and McCulloch, new species Plate 42, Figs. 14-21 Test elongate, slender, early portion strongly compressed and some- what coiled, later in a rectilinear series and nearly circular in section, initial end rounded ; chamber distinct, earlier ones very low and increas- ing gradually in height and becoming inflated ; sutures distinct, somewhat thickened, later ones depressed and more oblique; wall finely costate; aperture terminal, radiate, with a distinct neck. Length up to 3 mm.; diameter up to 0.40 mm. Holotype (AHF no. 68) from Station 411, 45 fms., north of Dun- can Island, Galapagos Islands. The microspheric forms of this species are like Vaginulina but the megalospheric forms might be placed in Dentalina if the others were not present. Stations: 328, 329, 330, 406, 411, 412, 429, 438, 450, 461, 474, 481, and 488. Distribution.—These records place this species off Cocos Island and in the waters of the Galapagos Islands. The depth range is 12 to 175 fms. with an average of 80 fms. The largest number of specimens were found in the sample off Albemarle Island in 80 fms. Genus FRONDICULARIA Defrance, 1824 Frondicularia gigas Church Plate 43, Figs. 1-4 Frondicularia gigas Church, Journ. Pal., vol. 3, 1929, p. 303, text figs. 1 2. Test very large, strongly compressed, about twice as long as broad, periphery rounded, initial end with two or three short but coarse spines ; chambers distinct, the earlier ones spiral, later taking on the typical inverted V-shape, increasing but slightly in height as added, slightly if 328 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 at all inflated; sutures distinct, often slightly depressed in the later por- tion; wall smooth. Length up to 8 mm.; breadth up to 3.5 mm. This large and distinct species was described from 30-40 fathoms, off Whites’ Landing, Santa Catalina Island, California, and has ap- parently not been recorded since. There are numerous typical specimens in the collections from off the California coast. Stations: 1056, 1057, 1117, 1128, 1130, 1135, 1136, 1143, 1144, 1158, 1159, 1165, 1168, 1177, 1180, 1221, 1224, 1230, 1246, and 2169. Distribution.—Stations 1056 to 1246 are off the Channel Islands. Beginning with Santa Cruz and Santa Rosa Islands on the north the depth range is 47 to 160 fms. off Catalina Island, the average depth being 61 fms. The additional record, Station 2169, is off Cedros Island in 55 fms. Station 1130 off San Pedro in 81 fms. yielded the largest number of specimens. Frondicularia californica Cushman and McCulloch, new species Plate 43, Figs. 5-8 Test of medium size for the genus, strongly compressed, periphery rounded, initial end with a single, short spine, early portion rapidly in- creasing in width, in the adult with the sides nearly parallel in the mid- dle then tapering rapidly toward the apertural end, in rare specimens with a third series of chambers developed in the last-formed portion at right angles to the main body of the test; chambers numerous, distinct, not inflated, rapidly increasing in length but only slightly increasing in height as added; sutures distinct, slightly thickened but not raised ; wall smooth; aperture radiate, terminal. Length of adult specimens up to 2.30 mm.; breadth 0.85 mm. Holotype (AHF no. 69) from Station 2009. This species differs from F. sagittula Van den Broeck in the more elongate form, initial end with a single spine, and nearly parallel sides ° in the adult. Stations: 1113, 1118, 1185, 1188, 1189, 1195, 1198, 1238, 2005, 2009, 2065, 2072, 2158, and 2160. Distribution.—The type locality is Inner Gorda Bank, Lower Cali- fornia, Mexico, 23° 00’ 50” N, 109° 31’ 05” W in 112 fms. Stations 1113 through 1238 are in the waters of the Channel Islands. The range beginning with 48 fms. off San Miguel Island, 40 fms. off Santa Bar- bara Island, 37 fms. off San Clemente to 160 fms. off Catalina Island, gives an average depth of 71 fms. Stations 2005-2160 off Mexico show No. 6 CUSHMAN, MCCULLOCH: LAGENIDAE 329 a range of depth from 44 to 163 fms. with the average being 88 fms. The largest number of specimens in one collection was off Santa Bar- bara Island in 40 fms. Subfamily Lageninae Genus LAGENA Walker and Jacob, 1798 Lagena acuticosta Reuss, var. Plate 43, Figs. 9, 10 A great many forms have been assigned to this species which like many species of Lagena is very variable. A group of these forms is figured here and other intermediate forms might have been included to show the close relationships of the different ornamentations.

Distribution Stations A-1 through 1246 show a continuous range from Alaska to numerous stations in the waters off the Channel Islands. The depth range established by these records is 2 to 340 fms. with the average being 56 fms. Stations 218 through 2167 are records with the exception of Station 291 in Concepcion Bay, Gulf of California, off the West Coast of Mexico showing a range of 10 to 250 fms., the average being 70 fms. Additional records from Hood Island, Gibraltar and Australia give an average depth of 40 fms. The numbers of specimens found in the several collections showed little variation as to abundance. Lagena amphora Reuss Plate 43, Figs. 11-14 This species has been placed by some authors as a variety of L. costata (Williamson) but seems to be quite different. The forms which we have figured as belonging to Reuss’ species have an elongate flask-shaped test, the basal end acute or slightly rounded, the apertural end much extended as in the type. The surface of the test has numerous high, elongate costae, some very long extending from the base of the test to the aperture with others limited to the body of the test and ending at the base of the neck. 330 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 EXPLANATION OF PLATE 43 Figs. 1-4.

Stations: Or. 10, 80, 1007, 1008, 1016, 1068, 1090, 1096, 1097, 1098, 1099, 1103, 1108, 1117, 1123, 1126, 1134, 1135, 1136, 1140, 1150, 1151, 1153, 1158, 1159; 1165, 1172, 1179; 1180; 1188, 11931201 zo 1206, 1218, 1220, 1222; 1223; 1225, 1228. 1230; 1232; 1234. 12366 1243, 1246, 218, 225, 227, 299, 2070, 2087, 2140, 2164, 2167, 315, 341, and 417. Distribution.—Stations 1007 through 1246 are in the waters off the Channel Islands with a depth range of 18 to 285 fms., the average being 72 fms. Stations off the coast of Mexico and in the Gulf of California show a depth range of 18 to 250 with an average of 90 fms. Stations off Central America, Panama and off Duncan Island, Galapagos show an average depth of 49 fms. The most specimens found in one collection was 1097 off Redondo Beach in 96-124 fms. Lagena apiculata Reuss, var. punctulata Sidebottom Plate 44, Figs. 1, 2 Lagena apiculata Reuss, var. punctulata Sidebottom, Journ. Quekett Micr. Club, ser. 2, vol. 11, 1912, p. 382, pl. 14, figs. 21-23; vol. 12, 1913, p. 165; Journ. Roy. Micr. Soc., 1918, p. 129. The figured specimens in their shape and peculiar surface somewhat suggest this variety described from the Southwest Pacific. They may pos- sibly belong in Entosolenia. Stations: 503, 509, and 563. Distribution.—Stations 503, 509, and 563 off Colombia, Ecuador, and Peru in 18, 45, and 19 fms. respectively. This species occurred rarely at these stations with a depth average of 27 fms. Lagena aspera Reuss Plate 44, Figs. 3, 4 Specimens with a generally globular form, long cylindrical neck usually with transverse costae, a slight lip, and the surface of the test with coarse spinose projections are referred to Reuss’ species. ‘The name has been very widely used and for a great variety of forms making a definite synonymy impossible without studying the specimens themselves. There is quite a difference between these specimens and those referred here to L. hispidula Cushman. No. 6 CUSHMAN, MCCULLOCH : LAGENIDAE 335 Stations: 82, 144, 1198, 1200, 546, 547, 557, and 637. Distribution Stations 82 through 1200 are all near Catalina Island with a depth range of 116 to 147 fms., the average being 123 fms. Off Panama and Colombia the depths average is only 35 fms. At Station 637, Kobe, Japan, the depth was only 7 fms. The numbers of specimens in each haul were approximately the same. Lagena chasteri Millett Plate 44, Figs. 5, 6 Lagena chasteri Millett, Journ. Roy. Micr. Soc., 1901, p. 11, pl. 1, fig. 11.—Sidebottom, Journ. Quekett Micr. Club, ser. 2, vol. 11, 1912, p. 398, pl. 16, fig. 31; vol. 12, 1913, p. 180.—Earland, Discovery Re- ports, vol. 10, 1934, p. 144. Our specimens are very similar to the type figures from the Malay Archipelago and also to those figured by Sidebottom from the Southwest Pacific. The flask-shaped test with broadly rounded base, gradually taper- ing apertural end, and the finely pitted surface are the characters which seem to distinguish this species. Stations: 1064, 1231, 2070, 409, 412, 413, 414, 417, 466, 468, 469, 472, and 473. Distribution —Two stations, 1064, and 1231, are off Santa Barbara and Santa Rosa Islands in 27 and 45 fms. respectively. Station 2070 is off Guadalupe Island, Mexico, in 250 fms. Stations 409-473 are in the waters of Galapagos Islands with an average depth range of 44 fms. This species seems to occur in greatest abundance off Charles Island. Lagena costata (Williamson) Plate 44, Fig. 7 Our specimens may be referred to Williamson’s species which has been used to include many different costate forms. Some of the forms referred to this species undoubtedly belong in Extosolenia. Stations: A-2, 2, 82, 110, 1086, 1096, 1151, 1160, 1163, 1165, 1168, 1178, 1205, 1228, 2070, and 414. Distribution.—Station A-2, Wrangell, Alaska has a depth record of 2 fms. Stations 2 through 1228, off the Channel Islands, show a depth range cf 18 to 250 fms. with 71 fms. for the average depth. Farther south at Guadalupe Island, and at Duncan Island, Galapagos the depths were 250 and 68 fms. respectively. More abundant material of these species was found off Santa Cruz Island in 46 fms. 336 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 Lagena clavata Williamson Plate 44, Fig. 13 Our figured specimen rather closely resembles the type figure of this species. The test is elongate and fusiform with the basal end drawn out into an elongate spinose projection and the apertural end with a very long tapering neck with a distinct lip. Many forms of very varying characters have been assigned to this species some of which evidently do not belong in Williamson’s species and it is impossible to give a complete synonymy. Stations: 3, 119, 1184, 235, 2070, 602, 626, 637, 653, 664, and 666. Distribution ——At only three local stations thus far has this species been discovered. Stations 235 and 2070 are off Mexico in a depth range of 17 to 250 fms. Station 602 is at Naples in 5 fms. Three different col- lections are from Kobe, Japan. These collections together with those from Colombo Bay and Bombay give a range of 5 to 45 fms.

This is a peculiarly ornamented species as may be seen from the vari- ous figures referred to it. Our specimens are not as complex in their ornamentation as some of the types but may be placed here until more material is available for study. Most of the records are from the North Atlantic off the British Isles but it is also recorded from the Malay region. Station: 312. Distribution.—This station is off the Secas Islands at Panama in 14 fms.

Distribution —One record, Station Or. 10, is off the coast of Oregon in 26 to 58 fms. Stations 84 through 1242 are all in the waters of the Channel Islands with a depth range of 10 to 340 fms., the average being 80 fms. Stations 2035 and 2036 extend the range southward into the Gulf of California at Angel de la Guardia Island in 46 to 75 fms. Sta- tion 312 places it off Panama in 14 fms. At present a greater abundance of these forms has been found off Santa Rosa, Santa Cruz, and Catalina Islands in 42 and 132 fms. respectively. Lagena distoma Parker and Jones Plate 44, Fig. 12 From the records this is a very variable species. It is elongate with a long spinose initial end and the apertural end with an elongate, slender neck, the main body of the test elongate with the sides nearly parallel in the middle, and the surface with numerous very fine longitudinal costae. Stations: A-2, A-16, 80, 1005, 1006, 1068, 1083, 1102, 1103, 1123, M158. 0161. 1192,1200; 1201, 1203; 1204, 1206, 1215, 1216, 1218; 1220; 1221, 1224, 1229, 1230, 1231, 1234, 1238, 1240, 1245, 1246, 213, 2070, 607, and 613. Distribution.—With the exception of the A-2 Station off Wrangell, Alaska, Stations 84-1242 are off the Channel Islands. The range in depth is 7 to 285 fms. with the average being 70 fms. Station 2070 places this species as far south as Guadalupe Island in 250 fms. Stations 607 and 613 are in European waters. he number of specimens seemed to vary greatly; the best records are for Wrangell, Alaska. 338 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 Lagena elongata (Ehrenberg) Plate 44, Fig. 14 Specimens, similar to that figured, with a very slender elongate test tapering at the base into a long spine and at the apertural end into an elongate slender neck, the central portion with the sides parallel for a large part of the length, and the wall smooth, may be referred to Ehren- berg’s species. These somewhat resemble L. distoma Parker and Jones but have a more cylindrical test and a smooth surface. Stations: Or. 10, 79, 80, 113, 114, 144, 1005, 1006, 1010, 1011, 1016, 1068, 1081, 1087, 1095, 1096, 1097, 1099, 1103, 1105, 1106, 1107, 1108, 1110, 1116, 1117, 1121; 1124,.1125,'1135, 1136; 1146, 1150;aiSe 1158, 1159, 1164, 1165, 1168, 1173, 1179, 1182, 1184, 1196, 1200, 1203, 1205, 1206, 1210, 1215, 1218; 1221,'1223; 1224, 1225, 1228, 1229ssu: 1234, 1239, 1240, 1244, 1245, 1246, 227, 265, and 2070. Distribution.—The first record is off the Oregon coast in 26 to 58 fms.; the Stations 79 through 1246 are in the waters of the Chan- nel Islands, with a depth range of 31 to 340 fms., the average depth being 88 fms. Two records off Guadalupe Island are 200 and 395 fms. In the Gulf of California at Angel de la Guardia Island the depth is 16 fms. Some of the best material came from the region of Guadalupe Island. Lagena cf. fieldeniana H. B. Brady Plate 44, Fig. 15 Specimens similar to that figured quite strongly resemble this species which from the records is rather widely distributed. Stations: 1205 and 1228.

Our specimens seem to belong to this species largely known living from the Pacific and recorded from the Pleistocene of Timms Point, near San Pedro, California. Stations: 82, 1008, 1010, 1016, 1044, 1082, 1095, 1096, 1106, 1108, 1109, 1110, 1116, 1117, 1121, 1125, 1136, 1143, 1148, 1149, 1150, 1157, 1165, 1167, 1168, 1177, 1184; 1200, 1211, 1215, 1218, 12235 1225 ;izeae 1238, 1239, 1246, 225, 2053, 2154, 415, 417, 516, 540, 547, 583, 606, and 609. Distribution.—Stations 82 through 1246 are in the waters of the Channel Islands with a depth range of 16 to 489 fms. the average being 53 fms. Stations 225-2154 off Mexico record 32 to 55 fms. Stations 415, 417 off the Galapagos and Stations 516 through 583 are all shallow water records 10 to 55 fms. with the average being 34 fms. Two additional records, Stations 606 and 609, Monaco and Balestrand, show a record of 8 and 32 fms. respectively. Only a few specimens were found in all of these collections. Lagena implicata Cushman and McCulloch, new species Plate 45, Figs. 5-7 Test elongate, the basal part truncated, the apertural end decidedly twisted outside of the line of the axis, sides of the main body of the test nearly parallel, becoming rapidly tapering at the apertural end with a distinct neck; wall ornamented with a few longitudinal costae some of which continue from the base to the apertural end, others intermediate do not extend onto the tapering portion. Length 0.45-0.65 mm. ; diameter 0.07-0.15 mm. Holotype (AHF no. 70) from Station 1201. This species differs from L. striatopunctata Parker and Jones, var. excentricitas Cushman and McCulloch, n. var., in the more slender form, and simple costae. It may be related to L. sesquistriata Bagg. Stations: 144, 1008, 1010, 1016, 1111, 1168, 1195, 1201, 1210, 1218, 1222, 1223, 1229, 1231, 1238, 1246, and 299. Distribution—The type locality is 2% miles SE Church Rock, Cata- lina Island, 33° 16’ 40” N, 118° 17’ 10” W in 80 fms. Stations 144 through 1246 are in the waters off the Channel Islands in depths from 38 to 120 fms., the average depth being 54 fms. An additional record, Station 299, is San Jose del Cabo, Mexico, in 82 fms. This species is not abundant at any station. NO. 6 CUSHMAN, MCCULLOCH: LAGENIDAE 341 Lagena inepta Cushman and McCulloch, new species Plate 45, Figs. 11-13 Test small, having the main body globular or slightly longer than broad, basal end broadly rounded, apertural end extended into a short, almost cylindrical, neck with a slight lip; wall ornamented with raised costae sometimes elongate toward the apertural end but usually making up a very irregular polygonal pattern. Length 0.25-0.30 mm.; diameter 0.15-0.20 mm. Holotype (AHF no. 71) from Station 215. This species differs from Entosolenia squamosa (Montagu) in its very definite neck, irregular surface ornamentation, and lack of an in- ternal tube. It somewhat resembles L. curvilineata Balkwill and Wright but differs in its more globular test and more definitely polygonal orna- mentation. Stations: 202, 205, 215, 514, and 557. Distribution —The type locality is Tangola-Tangola, Mexico, in 15- 20 fms. where it occurred in greater abundance. Other stations are off Mexico and South America in shallow waters with a depth range of 8 to 29 fms. Lagena laevis (Montagu) Plate 45, Figs. 14-16 Many forms have been assigned to this species. Those here figured seem closely related to L. perlucida (Montagu) but lack the costae at the base. Specimens vary considerably in the relative length of the main body of the test. Stations; Or. 7, Or..9,83, 1015, 1099, 1102, 1121, 1125, 1128; 1435, 1136, 1142, 1149, 1168, 1194, 1199, 1212, 1215, 1246, 218, 2070, 2135, 2162, 410, 458, 466, 474, 511, 514, 542, 543, 546, 629, and 660. Distribution.—In addition to the two records off the coast of Oregon, Stations 83 through 1246 are off the Channel Islands with a depth range of 17 to 490 fms., with an average being 82 fms. Stations 218 through 2162 are off the coast of Mexico with a depth average of 113 fms. Sta- tions 410-474 are off Galapagos Islands with a range from 9 to 175 fms., the average being 52 fms. Stations 511-546, off South America, have an average depth of 40 fms. Some specimens collected at Singapore in shal- low water were placed in this species also. 342 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 Lagena laevis (Montagu), var. baggi Cushman and Gray Plate 45, Fig. 17 Lagena laevis Bagg (part) (not Montagu), Bull. 513, U.

Res., 1946, p. 18, pl. 3, figs. 26, 27. Variety differing from the typical in the more nearly spherical body of the test, shorter neck and distinct and thickened lip and occasionally a short basal spine. This is a common form in the Pleistocene of Timms Point, near San Pedro, California, and the Recent forms in the Hancock collection seem identical. Stations: A-2, 109, 1154, 1159, 1178, 1215, 260, 418, 503, 513, and 519. Distribution.—Station A-2, Wrangell, Alaska, in 8 fms., Stations 109 through 1215, Station 412 in 111 fms. off the Galapagos Islands, 260 in the Gulf of California, Stations 503-519 extend the range south- ward in the Eastern Pacific. Some of the best material was found in the waters of the Galapagos Islands in 111 fms. Lagena laevis (Montagu), var. Plate 45, Fig. 18 The figured specimen seems related to L. laevis (Montagu) and in some respects to var. baggi Cushman and Gray. The basal end, however, is broad and has a peculiar spinose ornamentation. ‘The form is here figured for reference until more specimens show its true relationships. Station: 514.

Most authors have used it for forms similar to those here figured, a flask-shaped test with a short cylindrical neck and slightly developed lip, the base slightly truncate and the test thin and smooth with the exception of a series of short, longitudinal costae near the base of the test. Stations: A-16, Or. 10, 4, 39, 58, 76, 1008, 1093, 1108, 1123, 1125, 1210, 218, 225, 227, 229, 2089, 2137, 2154, 409, 413, 417, 450, 460, 468, 472, 514, 543, 602, 604, 606, 608, 609, 613, 615, 636, 640, 642, 649, 655, 659, and 664. Distribution.—These stations extend from Seward, Alaska, in 10 fms. southward along the coast to Station 543, Port Utria, Colombia, in 50 fms. Stations 602-655 are additional records from numerous ports all over the world. The average depth for all the stations is 25 fms. The specimens of this species seem to be rather abundant in the waters of the Galapagos Islands. Lagena perlucida (Montagu), var. Plate 46, Figs. 3, 4 The form represented by the figured specimens is difficult to place. It may be a variety of L. perlucida (Montagu) with the base having a few short, projecting spines rather than definite costae. Stations: A-2, Or. 9, Or. 10, 114, 1006, 1125, 1149, 460, 506, 542, 556, 603, 607, 608, 609, 613, 615, 622, 655, and 664. Distribution —Beginning with Station A-2, Wrangell, Alaska, in 8 fms. southward off the coast of Oregon in 35-58 fms., four stations off southern California in 30 to 132 fms., one station off James Island in 16 fms. and three stations off South America constitute the records thus far for this species in the shallow waters of the Eastern Pacific, the average depth being 45 fms. Stations 603-664 represent collections taken in many parts of the world with an average depth of 8 fms. 344 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 Lagena pliocenica Cushman and Gray Plate 46, Figs. 5-8 Lagena pliocenica Cushman and Gray, Contr.

Test with the main portion roughly triangular in longitudinal sec- tion, the sides slightly convex and the greatest width near the base; wall of the middle portion smooth but with a fine granular appearance and nearly opaque; base with a few raised costae radiating out from the center of the lower face; apertural end with an elongate, tapering neck orna- mented with longitudinal costae, occasionally tending to become slightly spiral. Length 0.30-0.40 mm.; diameter 0.25-0.28 mm. The types of this species are from the Pleistocene of Timms Point, near San Pedro, California. It has also been recorded from off the state of Washington and occurs in typical form in the Hancock collection. A series showing some of the variations is figured. Stations: 1, 1006, 1016, 1042, 1143, 1144, 1158, 1159, 1165, 1166, 1167, 1168, 1229, 1231, 1233, 1234, 1239, 1240, 2003, 2157, and 2163. Distribution—All but three of these stations are off the Channel Islands with the range in depth being 31 to 105 fms. The average depth is 50 fms. Stations 2003, 2157 and 2163, off the coast of Mexico, are not far distant from the Channel Islands.

Distribution.—Stations 4 through 1246 are off the Channel Islands with a depth of 6 to 240 fms. Stations 226 through 2169 constitute nu- merous records off the coast of Mexico and in the Gulf of California with a depth range of 10 to 200 fms. Stations 331 through 543 off Cen- tral America, Galapagos Islands and South America show a depth range of 7 to 50 fms. Station 653 places this species also at Kobe, Japan, in 45 fms. Lagena cf. striata (d’Orbigny) Plate 47, Figs. 1-4 The series of specimens figured on our plate shows a considerable amount of variation but in general seems to come within the limits of this species. Very many forms have been assigned to this species and no synonymy can be given with any degree of accuracy. d’Orbigny’s types were from off the Falkland Islands.

NO. 6 CUSHMAN, MCCULLOCH: LAGENIDAE 351 Distribution.—Stations 1006 through 1246 are off the Channel Is- lands with a depth range of 7 to 490 fms., with the average being 82 fms. Two records are off Mexico, one off Central America and one off the Galapagos Islands with a depth range of 15 to 48 fms. Stations 503 through 563 are off the coast of South America from shore to 50 fms. Stations 606 through 661 are collections from ports around the world in depths from shore to 270 fms. Lagena striatopunctata Parker and Jones Plate 47, Figs. 5-9 It is difficult to give a full synonymy of this species or a complete description. Many forms have been assigned to it. There is a wide varia- tion in the specimens in the Hancock collection and a number of these are here figured to show this range. Stations: A-2, 80, 1007, 1042, 1064, 1151, 1153, 1158, 1160, 1161, 1164, 1165, 1167, 1168, 1176, 1184, 1185, 1186, 1207, 1210, 1211, 1219, 1220'91223) 12281230, 1232, 1233, 1238, 1239, 1240, 1243, 1246, 227, 258, 2008, 2036, 2063, 2070, 2156, 2157, 409, 417, 460, 461, 478, and 608. Distribution.—Stations 80 through 1246 are stations off the Channel Islands with a depth range of 27 to 489 fms., the average depth being 106 fms. Stations 227 through 2157 are off Mexico and in the Gulf of California with a depth range of 41 to 450 fms. Five stations, 409-478, show a similar range, 16 to 80 fms. with 42 for the average depth. Sta- tion 608 is located in European waters. Specimens were not numerous at any of these stations.

The specimens with the intermediate area with fine pits in longitudi- nal lines are referred to Sidebottom’s variety. he types are from the Southwest Pacific and it is recorded from the Pleistocene of ‘Timms Point, near San Pedro, California. _ Stations: 1005, 1006, 1009, 1071, 1150, 1157, 1159, 1160, 1168, P21851226.5 1297-1 230,01282,:1233,. 1234,1238, 1239, 1242299) and 2070. 352 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 Distribution.—With two exceptions all of these stations are off the Channel Islands in 47 to 212 fms. with 65 fms. being the average depth. Stations 299 and 2070 off Mexico are 82 and 250 fms. in depth respec- tively. Specimens of this species were not abundant in any of the col- lections. Lagena striatopunctata Parker and Jones, var. excentricitas Cushman and McCulloch, new variety Plate 47, Figs. 12, 13 Variety differing from the typical form in the axis of the test decided- ly bent at the apertural end, and the costae fewer and more prominent. Holotype of variety (AHF no. 72) from Station 468. This varietal form in our material seems rather distinctive but like the other varieties shows a considerable degree of variation. It is some- what like specimens from the Tropical Pacific referred to L. desmophora Rymer-Jones (Cushman, Bull. 161, U. S. Nat. Mus., pt. 2, 1933, pl. 7, figs. 11-14) but the present form has fewer costae and a more rounded base. Stations: 1160, 1246, 329, 409, 414, 435, 461, 468, 472, 473, and 474. Distribution.—Station 468, the type locality is Charles Island one- half mile south of Black Beach in 20 fms. Stations 409 through 474 are additional records from the Galapagos Islands with a range of 15 to 175 fms., the average being 56. Lagena striatopunctata Parker and Jones, var. cista Cushman and McCulloch, new variety Plate 47, Figs. 14, 15 Variety differing from the typical form in the axis of the test de- cidedly bent at the apertural end, in having somewhat fewer but very distinct costae and the intermediate wall areas nearly filling the inter- costal space and flush with the costae as shown in end view, the wall in between the costae almost transparent, and the main body of the test elongate box-shaped with the walls parallel in their middle parts. Holotype of variety (AHF no. 73) from Station 461. Stations: 1068, 1195, 227, 411, 417, 460, 461, 466, 468, 473, 478, 543, and 547. Distribution.—Station 461, the type locality is Tagus Cove, Albe- marle Island, in 80 fms. Additional records in the Galapagos Islands are Stations 460 through 478 showing a depth range of 16 to 80 fms., the No. 6 CUSHMAN, MCCULLOCH: LAGENIDAE 353 average being 42 fms. Two records off the Channel Islands, Stations 1068 and 1195, are in 39 and 50 fms. respectively. One record, Station 227, is off Mexico in 200 fms. Off South America, Stations 543 and 547 are 50 and 40 fms. respectively, more specimens seemed to be present in Tagus Cove in 80 fms. Lagena striatopunctata Parker and Jones, var. gemma Cushman and McCulloch, new variety Plate 47, Fig. 16 Variety differing from the typical form in the perforated costae being more numerous, low and rounded, leaving almost no intercostal areas, and thus the test appears to be almost entirely covered with beading in longitudinal lines. Holotype of variety (AHF no. 74) from Station 468. Somewhat similar forms are figured by Millett from the Malay Archipelago (Journ. Roy. Micr. Soc., 1901, p. 489, pl. 8, fig. 6) and by Sidebottom from the Southwest Pacific (Journ. Quekett Micr. Club, ser. 2, vol. 11, 1912, p. 392, pl. 16, figs. 7, 8, 10) but our specimens differ in having a rounded, not truncated, base. Stations: A-20, 256, 2008, 2035, 2097, 466, 468, 573, and 583. Distribution.—Station 468, the type locality, is one-half mile south of Black Beach, Charles Island, in 20 fms. Additional records include A-20, Anderson Bay, Alaska, shore collecting. Stations 256-2097 are all off Mexico with a depth range of 38 to 70 fms. with the average being 65 fms. Station 466 is off Charles Island in 23 fms. and two stations are off South America in 15 and 10 fms. respectively. Specimens were not numer- ous at any of the stations.

It is difficult to determine whether this spirally costate form should be regarded as a variety or a distinct species. In our present material there seems to be intermediate forms which would suggest a varietal stand- ing for this form. Not all the references are given but only the Recent ones that seem to belong here. Stations: 214, 2070, and 616. Distribution.—Stations 214 and 2070 are off Clarion and Guadalupe Islands in 15 and 250 fms. respectively. Specimens from Station 616, Nole Island, Whit Sunday, Australia, collected at low tide, have been placed here also. The best material was found off Clarion Island in 157 fms. Lagena striatopunctata Parker and Jones, var. tricosta Cushman and Gray Plate 47, Figs. 19, 20 Lagena striatopunctata Parker and Jones, var. tricosta Cushman and Gray, Special Publ. No. 19, Cushman Lab. Foram. Res., 1946, p. 21, pl. 4, fig. 5. Variety differing from the typical form in having three prominent raised perforated costae nearly equally placed on the surface of the test. The types of this variety are from the Pleistocene of Timms Point, near San Pedro, California. Recent specimens in the Hancock collection have the three prominent perforated costae usually in a somewhat twisted position as shown in our figures and seem to be included under this variety. Stations: 258, 2131, and 510. Distribution.—Station 258 in the Gulf of California, San Francis- quito Bay in 16 fms., Station 2131, north of Isla Partida, Mexico, in 62-85 fms. and Station 510, San Francisco Bay, Colombia, extend the range southward from San Pedro. The specimens were rare at all of these stations. Lagena striatopunctata Parker and Jones, var. Plate 47, Figs. 21, 22 A few specimens, two of which are figured, are evidently closely re- lated to this species but have the base somewhat truncated and the costae extended backward and slightly projecting. They suggest Lagena plumi- gera H. B. Brady in some characters but seem to belong distinctly within the varietal group of L. striatopunctata. No. 6 CUSHMAN, MCCULLOCH: LAGENIDAE 355 Station: 2070. Distribution.—Station 2070 is off Guadalupe Island, Mexico, in 250 fms. Lagena submagnifica Cushman and Gray Plate 48, Fig. 1 Lagena submagnifica Cushman and Gray, Special Publ. No. 19, Cush- man Lab. Foram. Res., 1946, p. 22, pl. 4, figs. 12-15. “Test with the body nearly spherical, but slightly longer than broad, base rounded, apertural end with a very long, tubular neck and a slightly developed lip; surface with very fine spinose projections with a tendency to fusion at the surface, especially at opposite sides of the test, but easily broken away. Length 0.45-0.55 mm.; diameter 0.23-0.27 mm.” The types of this rather unique species are from the Pleistocene of Timms Point, near San Pedro, California. It is of interest, therefore, to find typical specimens in this Recent Hancock collection. Stations: 1097; 1107, 1118, 1125, 1132; 1135, 1136; 1139; 1148; 1149, 227, 269, 415, 417, 512, and 513. Distribution.—Stations 1097-1149 are off the Channel Islands with a depth range of 26 to 340 fms., the average being 96. Stations 227 and 269 are off Guadalupe Island in 200 fms. and off Angel de la Guardia in 125 fms. Stations 415 through 513 are off the Galapagos Islands and the coast of South America in 48 to 58 fms. This species was not abun- dant at any of these stations. Lagena cf. suleata (Walker and Jacob) Plate 48, Fig. 2 Many different forms have been assigned by various authors to this species. The form here figured is referred to it with some question and the synonymy is not given as so many of the records are without figures or show such a variety of forms.

Distribution. —Station Or. 10, Winchester Bay, Oregon, in 26-58 fms. is the most northern record in this study. Stations 1007 through 1243 are off the Channel Islands, the depth ranging from 54 to 489 fms. with the average depth being 136 fms. Stations 2057-2097 off the coast of Mexico in 23 to 255 fms. and Station 542, Gorgona Island, Colombia, extend the range southward. Stations 606-659 place this species in widely scat- tered ports: Monaco, Leish, Rotterdam and Capetown. This species was not abundant at any of these stations. 356 ALLAN HANCOCK PACIFIC EXPEDITIONS VOL. 6 EXPLANATION OF PLATE 47 Figs. 1-4. Lagena cf. striata (d’Orbigny). X 65, p. 350. 5-9.

Variety differing from the typical in having the basal end drawn out into a stout spine, the apertural end with a tapering cylindrical neck with a phialine lip, usually without other ornamentation, body of the test with numerous longitudinal costae as in the typical form. This variety is fairly common in the Pacific in fairly deep water. As will be noted from the figures, there is a considerable amount of variation in the forms assigned to this variety but they seem to form a continuous series.

No. 6 CUSHMAN, MCCULLOCH : LAGENIDAE 361 Distribution —Beginning with Station A-1, Ketchikan, Alaska, south- ward with Stations 2 through 1246 the depth range is from 8 to 175 fms., with the average depth being 56 fms. Another series of stations off Mexi- co, Stations 202-2169, give a depth range of 8 to 200 fms. with 54 fms. being the average. Stations 409 through 556 off the Galapagos Islands and the coast of South America show records of 5 to 175 fms. Stations 601 to 661 include ports all over the world giving additional shallow water records. More material was found in the stations off Galapagos than elsewhere.

It is probably related to forms that have been assigned to L. acuticosta Reuss. In the Hancock material it is quite variable and two unusual forms are figured on our plate. One of these has the costae in a distinct spiral and the other has them bifurcate toward the base.
