Description. — Test obliquely nautiloid, subglobular, inaequilateral, 

 the outer volution consisting of about five chambers and covering 

 the early portion of the test entirely; chambers inflated but the sut- 

 ures very slightly depressed; wall smooth, distinctly punctate, 

 shiny; aperture elongate, narrow, curved, between the ventral face of 

 the last-formed chamber and the adjacent volution with the chamber 

 wall forming a rounded lip. 



Diameter from 0.50 mm. to nearly 1 mm. 



Distribution. — This is a truly pelagic species and its distribution is 

 almost ocean wide. In the Albatross collections it is widely scattered 

 over the region in which dredgings were made. 



The coarsely punctate test and large aperture fit the species for a 

 pelagic existence, but make it seem very, different from either P. 

 sphaeroides or P. quinqueloba in most of its characters. Their generic 

 differences would seem to be a matter worthy of consideration. 



Pullenia obliquiloculata — material examined.
