Description. — "The test is more or less compressed, and has six 

 to eight visible segments which are somewhat oblong and inflated in 

 contour and separated by excavated sutures." 



Brady records this species from the North Pacific down to 2,050 

 fathoms. The species is recorded by Bagg, but an examination of 

 his specimens show it to be an Uvigerina with a phialine lip on the 

 opposite end from which the aperture would be if the specimen were 

 a Polymorphina of this species. The description and figure are from 

 Brady.

Description. — Test broadest at the apertural end, tapering rapidly 

 toward the initial end; chambers several, earlier ones with slightly 

 depressed sutures, later ones inflated, sutures deeper; aperture pro- 

 duced, radiate; wall smooth or with a slight indication of strise. 



Length 1.50 to 2 mm. 



Distribution. — Brady records this species from Challenger station 

 224 in 1,850 fathoms. I have had material from Nero station 1287 

 in 1,606 fathoms between Guam and Japan.

Description. — Test similar to Polymorphina communis, but the 

 sutures less denned; chambers less inflated, apical end less rounded, 

 whole test more fusiform.
