sometimes slightly convex; chambers somewhat inflated; sutures 

 somewhat depressed, about 12 to 16 chambers in the last formed 

 volutions; periphery rounded; wall coarsely perforate, more so on 

 the ventral side ; aperture at the middle of the base of the periphery 

 of the chamber. 



Diameter 0.8 to 1.25 mm. 



Distribution. — Brady records this species in anchor mud from 

 Hongkong; Bagg, from 12 out of 19 Albatross stations off the Ha- 

 waiian Islands from which he had material, depths ranging from 104 

 to 1,544 fathoms, and Rhumbler records one young specimen from 

 Chatham Island.
