biserial in character; finally the main portion of the test, which is uni- 

 serial. the chambers extending back along the angles of the test, arched 



upward across the faces, leaving a 

 slight hollow below; wall arenace- 

 ous but smoothly finished on the 

 exterior: aperture in the uniserial 

 portion circular, in the middle of 

 the apertural face, with a single 

 valvular tooth. 



Length up to 1.25 mm. 

 Distribution. — There is but one 

 record for this species in the North 

 Pacific, that given by Bagg, from 

 Albatross station D4017, in 305 

 fathoms, off the Hawaiian Islands. 

 1 have examined Bagg's specimen 

 and it seems without doubt to be 

 this species, although the test is not entire. It has been found in 

 various parts of the other oceans, usually in rather shallow water.
