Ijlstribntion. — Tliis is a truly pelagic species, having been taken in 

 all the great ocean basins, especially in tropical and subtropical 

 waters. In the Albatross bottom samples it occurred only in those 

 from tlie Caribbean, where it seldom occurred in any considerable 

 numbers. It is recorded from the coast of the British Isles in the 

 warm area of the Faroe Channel (Pearcey), and a single specimen 

 was found at 750 fathoms (1,370 meters) off the southwest of Ireland 

 (Wright). 



The plate of figures of this species is from the Challenger report, as 

 all the bottom samples are largely without spines.

Description. — Test generally trochoid, usually with the spire 

 somewhat compressed and the later chambers often irregular; cham- 

 bers numerous, rapidly increasing in size as added, inflated; wall 

 usually clear and translucent, in old-age specimens occasionally 

 thickened and opac^ue; apertur-es numerous, elliptical in form, placed 

 in a somewhat regular manner along the sutural lines between the 

 chambers. 



This genus described by D'Orbigny in his Cuban Monograph is 

 often abundant in some of the bottom samples of the West Indian 

 region, especiall}^ in the Caribbean. It is recorded from the other 

 great ocean basins, but never seems to be abundant elsewhere than 

 in the West Indian region from which it was first described. 



In spite of its being in general form like certain other members of 

 the Globigerinidae, its early development occasionally has very much 

 the character of some of the Rotaliidae. The early chambers are 

 often of a dark-brown color, such as is found in numerous genera of 

 the Rotaliidae, and there seems "to be no real reason Avhy it should 

 not be placed in that family rather than in the Globigerinidae.
