Test elongate, subcylindrical, sides nearly parallel, ends broadly 

 rounded; chambers obscured by the surface ornamentation, not inflated; 

 sutures largely obscured; wall ornamented vi^ith longitudinal costae, 

 somewhat irregularly spiral, running the entire length of the test to the 

 . aperture in a radiate pattern ; aperture small, circular, in the center of 

 the depressed apertural face. Length up to 0.50 mm; breadth 0.18-0.22 

 mm. 



This species is widely distributed in the warmer waters of the present 

 oceans. 



Stations: Aus-2, 222, 252, 2067, 2084, 2149. 



Distribution. — There are a few specimens from the Eastern Pacific, 

 from the coast of lower California, along the coast of Mexico with a

Test conical, only slightly longer than broad, little if at all com- 

 pressed, expanding very slightly toward the apertural end, bluntly pointed 

 or rounded at the initial end ; chambers only slightly inflated, about five 

 pairs making up the final whorl; sutures distinct, slightly depressed; wall 

 smooth; aperture elongate, slightly curved, oblique at the base of the 

 apertural face with a secondaiy aperture consisting of a narrow slit at 

 the basal margin. Length 0.36-0.40 mm ; breadth 0.20-0.23 mm. 



The only previous records for this species are from the Miocene of 

 the Vienna Basin. 



There are two specimens very close to and apparently identical with 

 this species from off Gibralter, Station 648.
