FORAMINIFERA OF THE ATLANTIC OCEAN 



75 



This much smaller, more compressed species from the shallow- 

 waters of the western tropical Atlantic seems to be distinct from that 

 of the deeper water and of the cooler waters of the eastern Atlantic. 

 The form I described from the Tortugas should probably belong with 

 that described by d'Orbigny, and the apparent differences may be 

 probably due to the lack of details in d'0rbign3''s figure. 



The species ranges from the coast of Brazil to the coast of Florida 

 but in shallow water only. It occm-s fossil in the Miocene, Choc- 

 tawhatchee marl, of Florida.

Genoholotype. — Baggina calif ornica Cushman. 



Test subglobular, trochoid; chambers relatively few, dorsal side 

 with the chambers in the adult more or less involute, the ventral side 

 completely so; chambers large and inflated; wall calcareous, perforate, 

 with a clear lunate space of small size on the chamber above the 

 aperture; aperture broadly oval on the ventral side of the last-formed 

 chamber, without a lip. 



Miocene to Recent. 



Typical living species seem to be confined to the Indo-Pacific 

 although Earland has recorded ''Pulvinulina hauerii d'Orbigny" 

 from shore sands of Bognor, England. This is the only record.
