Description. — Test usually free, ventral face flattened or concave, 

 dorsal face strongly convex; peripheral margin sharp, keeled; cham- 

 bers numerous, 7-9 in final whorl, all visible from the ventral face, 

 only those of the last-formed whorl visible from the dorsal face; 

 sutures slightly depressed, somewhat limbate; wall fairly smooth, 

 punctate; aperture a narrow slit at the inner margin of the chamber. 



Diameter up to 1.4 mm. 



Distribution. — Bagg records this species from several Albatross 

 stations off the Hawaiian Islands at depths ranging from 104 to 1,544 

 fathoms. I have had the species from several Albatross stations in 

 the same region, depths ranging from 373 to 607 fathoms. At 

 Albatross station H2768 in 373 fathoms the species was represented 

 by abundant specimens. It also was noted from Nero station 1328 

 in 871 fathoms between Guam and Yokohama.
