Description. — Test broadly ovate to subcylindrical, chambers 

 numerous, inflated, with distinct sutures; wall with large, well- 

 developed costas, placed longitudinally, apical end rather bluntly 

 rounded, the earliest chambers visible with costse plainly developed; 

 aperture with a short, stout tubular neck and a distinct phialine lip; 

 color of the test white to a light brown. 



Length 0.5 to 1 mm. 



Distribution. — This species is one of the most widely distributed 

 of the family, being found in all the ocean basins. In the North 

 Pacific, Brady speaks of it as rare, but this was due to simple lack of 

 material, for I found it widely distributed in all parts running north- 

 ward into Bering Sea, where it is very common at several stations. 

 As a rule it seems to be most abundant in cold waters and at the 

 north in shallow water, while southward toward the Equator it seems 

 to occur most frequently at a considerable depth where the water is 

 again cold. Brady recorded the species from the Hawaiian Islands 

 and Bagg records it from the same region at five Albatross stations. 

 Goes records it from two stations off the west coast of America, one at
