FORAMINIFERA OF THE NORTH PACIFIC OCEAN. 47 



In the material at my disposal typical specimens have occurred 

 but few times: At Nero station 990 in 859 fathoms off Guam and 

 1254 in 264 fathoms between Guam and Japan, at Albatross station 

 H2986 in 271 fathoms off the Hawaiian Islands, and Tuscarora 

 station 1 in 206 fathoms, 21° 10' N. ; 158° 04' W. From the material 

 I have had this species is not as common in the North Pacific as some 

 of the others of the genus.

Description. — Test nautiloid, nearly equally biconvex, ventral side 

 concave, dorsal convex; umbilical region on ventral side depressed; 

 seven to eight chambers in the 

 final coil, in face view broad ; pe- 

 riphery broad, angled, some of 

 the chambers with a single large 

 toothlike projection at the pe- 

 riphery; wall coarsely peif orate; 

 aperture an elongated arched slit 

 at the base of the chamber. FlG " 52 -- a *omalina polymorph* costa. 



after Brady. 



Diameter up to 1.5 mm. 



Distribution. — Bagg has recorded this species from several Albatross 

 stations in the vicinity of the Hawaiian Islands, depths ranging from 

 305 to 1,274 fathoms. I have had it from numerous stations off the 

 Hawaiian. Islands, off Guam, and off Japan, depths ranging from 271 

 to 2,067 fathoms.
