Test plano-convex, compressed, dorsal side slightly convex, ventral 

 side flat or somewhat concave, umbiiicate, peripheral margin thin, 

 slightly lobulated, carinate; chambers usually six in the last-formed 

 coil; sutures somewhat depressed, especially below, on the dorsal 

 side limbate and curved, ventrally simply depressed, straight, in a 

 radial position; wall usually smooth and punctate, but sometimes 

 slightly granular; aperture a rather well-developed opening at the 

 umbilical end of the chamber, with a projecting valvular lip. 



This is a very abundant species of Globigerina-ooze of the western 

 Atlantic. There seems to be a maximum size reached by this species 

 in the Caribbean, and northward and southward the specimens are 

 smaller.^^ 



This species occurs in the later Tertiary of the coastal plain of the 

 United States and elsewhere. It is related to Globorotalia mem- 

 branacea (Ehrenberg) which was widely distributed in the Globigerina- 

 ooze of the Upper Cretaceous of widely separated regions.
