Description. — -Test compressed, composed of twelve to fifteen 

 chambers in the last formed volution, chambers much longer than 

 broad, sutures much curved, in face view test about 2\ times as long 

 as wide, periphery subacute, scarcely if at all lobulated; umbilical 

 area filled with shell tissue, sutures limbate; surface nearly smooth, 

 wall very finely punctate ; aperture a narrow curved slit at the base 

 of the apertural face of the chamber, simple. 



Diameter 0.50-0.75 mm. 



Distribution. — The only Challenger record which Brady gives is 

 Hongkong harbor in 7 fathoms. Flint records it from the Gulf of 

 Tokyo in 9 fathoms. I have had it from off the Hawaiian Islands, 

 Albatross H 2917 in 2,615 fathoms. It has also occurred at D 4964 

 in 37 fathoms, bottom temperature 66.6° F. off Japan. From the 

 Nero material it occurred at station 1237 in 613 fathoms off Yoko- 

 hama, Japan, and 1444 in 2,175 fathoms between Yokohama and 

 Guam. 



This is a rather characteristic species with its numerous chambers 

 in a rapidly increasing width of volution and peculiar umbilical region.
