Genoholotype. — Pulvinulina menardii, var. tumida H. B. Brady. 



Test trochoid, the earhest chambers often like Globigerina, with a 

 rough cancellated exterior, biconvex, on the dorsal side more or less 

 flattened with the ventral side strongly convex; wall calcareous 

 perforate, frequently spinose in whole or in restricted areas; aperture 

 large, opening into the umbilicus which is either open or partially 

 covered by a lip. ^ 



Upper Cretaceous to Recent. ^.J 



This genus is derived from the Globigerinidae, and like many of the 

 members of that family seems to be adapted to pelagic conditions as 

 were many of the fossil species.
