FORAMINIFERA OF NORTH PACIFIC OCEAN.

Distribution. — The only published records for the North Pacific are 

 those of Flint, who found it in the Nero material from three stations. 

 I have found it in material from two of these same stations and from 

 a number of others, most of them northwest of the Hawaiian Islands. 

 It occurred also near the Bonin Islands and at one Albatross station, 

 H2902, east of the Hawaiian Islands. All of these records are from

rather deep water, ranging from 1,321-2,203 fathoms, mostly from 

 globigerina ooze. 



The Challenger records for this species are all from the South Pacific, 

 in rather deep water. This species is much more robust than the 

 preceding; the shorter and stouter spines and the broad last formed 

 chamber with its ornamentation of radial lines and the shape of the 

 aperture are all very different from the conditions seen in E. serrata.
