chambers few, embracing, the last-formed one making up two-thirds 

 or more of the visible test, sutures flush but marked by a distinct 

 fine line; apical end somewhat rounded, usually with radiate lines 

 about the aperture; wall smooth. 



Length 2 mm. or more. 



Distribution. — Brady records this species from the North Pacific 

 in 7-95 fathoms. The latter depth represents the Challenger station 

 off the Philippines. Goes records it at four Albatross stations in the 

 eastern Pacific, D3371 in 770 fathoms, D3375 in 1,201 fathoms, D3376 

 in 1,132 fathoms, and D3407 in 885 fathoms. Bagg records it from 

 three stations off the Hawaiian Islands, Albatross D4025 in 275-368 

 fathoms, H4555 in 1,398 fathoms, and H4696 in 367 fathoms. I 

 have had material from the western portion of the region, Albatross 

 D4843, off the coast of Korea in 100 fathoms, bottom temperature 

 39.9° F.

Description. — Test elongate, usually somewhat arcuate, composed 

 of a few elliptical chambers in adult specimens three to five in num- 

 ber; wall smooth or occasionally with a few very delicate hispid 

 spines, wall transparent; both ends broadly rounded, smooth; aper- 

 ture a simple opening without neck. 



Length 0.50-1.00 mm. 



Distribution. — Brady records this species in the North Pacific at a 

 single Challenger station off the Philippines in 95 fathoms. Bagg 

 records it at a single Albatross station, H4508, in 495 fathoms off the 

 Hawaiian Islands. I have a single specimen here figured, plate 25, 

 figure 6, from Nero station 1313, in 1,716 fathoms, between Guam 

 and Japan. 



This seems in all its characters to be a primitive species and one 

 with little character except the form, the few chambers, and the 

 transparent wall of the test. These elementary characters, however, 

 seem to be rather constant.
