may occur with early chambers arranged trocho- 

 spirally, in the adult the globigerine coil may remain 

 visible at one side, or may be completely enveloped by 

 the final spherical chamber, or the test may consist of 

 a nvunber of completely enveloping and concentric 

 globular chambers; wall calcareous, perforate, radial in 

 structure; primary aperture interiomarginal, mnbilical 

 in the early globigerine stage, where this is present, 

 but areal in the adult, with numerous small openings 

 which may be scattered over one side or over much of 

 the test, small sutural secondary openings commonly 

 found around the early globigerine chambers of speci- 

 mens where these are visible at the surface. 



Remaeks: As shown by Bronnimann (1951a, p. 133) 

 there is a variation from the completely spherical single 

 chamber to the more rare 2- or even 3-chambered forms, 

 and to those forms with a globigerine coil either com- 

 pletely or partially enclosed by the globular end 

 chamber. Biorhulina and Candorbulina are therefore 

 synonyms of Orhvlina. Unilocular, bilocular and tri- 

 locular forms are here illustrated, as well as those of 

 "Candorbulina" type with globigerine coil visible at 

 one side. 



Types and occukrence: Figured hypotype of 

 Orbulina universa d'Orbigny (USNM P3910) from 

 Albatross Station D.2377, lat. 29°07'30" N., long. 

 88°08'00" W., in gray mud at 210 fathoms; 3-cham- 

 bered hypotype (USNM P3911) from Albatross Station 

 D.2042, lat. 39°33'00" N., long. 68°26'45" W., depth 

 1,555 fathoms; 2-chambered hypotype (USNM P3909) 

 such as was named Biorbulina, from Albatross Station 

 D.2660, lat. 28°40'00" N., long. 78°46'00" W., depth 

 504 fathoms; hypotype of Orbulina universa d'Orbigny 

 (USNM P3908) showing "Candorbulina" development 

 of test from the Miocene Choctawhatchee formation 

 (lower Area zone) near head of Vaughan Creek, 

 Sec. 27, T.2 N., R. 19 W., Walton County, Florida; and 

 figured hypotype (USNM P3907) showing "Candor- 

 bulina stage of development from the Miocene, Baden 

 near Vienna, Austria. 



Range: Miocene to Recent. 



Catapsydracinae Bolli, Loeblich, and Tappan, 

 new subfamily 



Type genus : Catapsydrax, new genus. 



Test trochospirally coiled to enveloping; chambers 

 spherical to ovate; primary apertvu-e umbilical, may 

 have secondary sutural or areal apertm-es, apertures in 

 the adult covered by bullae and with infralaminal 

 accessory apertures. 



Range : Middle Eocene to Recent. 



Catapsydrax Bolli, Loeblich, and Tappan, new genus 



Plate 7, PiauBES 6ar-8o 



Type species: Globigerina dissimilis Cushman and 

 Bermudez, 1937. (Derivation: Kata, Gr., down, below 

 -t- psydrax, Gr., blister; gender, masculine.) 



Test free, trochospiral; chambers spherical to ovate; 



sutures depressed, radial; wall calcareous, perforate, 

 radial in structvu'e, surface smooth or pitted; primary 

 aperture interiomarginal, umbilical, in the final stage 

 covered by a single umbilical bulla, with one or more 

 accessory infralaminal apertures. 



Remarks : Catapsydrax, new genus, differs from Glo- 

 bigerina d'Orbigny in the presence of the umbilical buUa 

 covering the primary aperture, and in having the acces- 

 sory infralaminal apertm-es. 



It differs from Globigerinita Bronnimann in having a 

 small umbilical buUa with relatively few infralaminal 

 accessory apertures which are sutural in position. In 

 Globigerinita the bulla spreads along the sutures and 

 the accessory apertures occiu: all along its margins. 



Catapsydrax resembles Globigerinxitheka Bronnimann 

 in having the bulla but differs in having a single lun- 

 bilical one, rather than more than one, situated in 

 sutural positions. 



Types and occtjrrence: In addition to the type 

 species, C. dissimilis, three new Tertiary species of this 

 genus are here described. 



Catapsydrax dissimilis was originally described as 

 Globigerina dissimilis Cushman and Bermudez. The 

 holotype (Cushman Coll. 23430) and paratypes (Cush- 

 man Coll. 23429) are from the Eocene, 1 kilometer 

 north of Arroyo Arenas, on road to Jaimanitas (water 

 well), Havana Province, Cuba. Collected by P. J. 

 Bermudez. 



Figured hypotypes (USNM P4218a, b) are from the 

 Oligocene Cipero formation, Globigerina ciperoensis 

 zone, Cipero Coast section, 'Trinidad, B. W. I. Col- 

 lected by H. M. Bolli. 



Range: Upper Eocene to Miocene. 



Catapsydrax parvulus Bolli, Loeblich, and Tappan, new species 

 Plate 7, Figures lOa-c 



Test free, tiny, subglobular, low trochospiral, periph- 

 ery broadly rounded; chambers ovate, increasing rap- 

 idly in size as added, foiu- to five per whorl, mostly with 

 four in the final whorl; sutiures distinct, slightly de- 

 pressed, oblique, somewhat curved on the spiral side; 

 wall calcareous, finely perforate, surface smooth; pri- 

 mary apertm-e interiomarginal, umbilical and covered 

 over by an arched bUsterlike bulla, with a single very 

 low arched or shtlike infralaminal accessory aperture 

 opening at one side. 



Greatest diameter of holotype 0.16 mm., thickness 

 0.13 mm. Paratypes range from 0.13 to 0.18 mm. in 

 diameter. 



Remarks: This species differs from Catapsydrax dis- 

 similis (Cushman and Bermudez) in its much smaller 

 size, being about one-fourth the diameter; in the less 

 globular and less inflated chambers and more even 

 periphery; and in having only a single infralaminal ac- 

 cessory aperture rather than two to four. 



Types and occurrence: Holotjrpe (USNM P4219) 

 and unfigured paratypes (USNM P4822) from the 

 Miocene Lengua formation {Globorotalia mayeri zone), 

 in a ditch on the north side of Cunjal Road, southern 

 Trinidad, B. W. I.
