Description. — Test composed of a proloculiim and long, undivided 

 second chamber, at first planospiral like Ammodiscus, but soon leav- 

 ing the one plane and becoming irregularly; coiled wall finely arena- 

 ceous with much cement; color reddish or yellowish brown. 



Diameter 0.25-0.84 mm. 



Distribution. — There are seven Challenger records for this species 

 in the North Pacific, six of them in the abyssal region from Japan 

 westward to the mid-Pacific and thence southward to the equator, 

 the other one between Hongkong and Manila. These stations range

in depth from 1,875 to 3,125 fathoms, mostly in red clay areas. The 

 only other North Pacific record is that of Flint, Albatross station 

 D3080, in 93 fathoms off the coast of Oregon. 



Many of the figured fossil specimens are very peculiar, and a ques- 

 tion may be raised as to whether they all belong to this species.
