somewhat irregular; last one or two chambers usually smooth, 

 carinate; aperture, in end view, central, terminal, broadly oval, 

 with a raised, rounded border; color white. 



Length 0.60-0.75 mm. 



Distribution. — I have specimens of this species from Nero station 

 990, in 859 fathoms, off Guam. The oval specimens of Brady referred 

 to above were from off Raine Island, Torres Strait, in 155 fathoms; 

 in Humboldt Bay, off New Guinea, in 37 fathoms; and off Amboina, 

 in 15-20 fathoms. Goes's specimen" does 

 not belong here. 



This species differs in several important 

 characters from the typical form described 

 by d'Orbigny. From the available records 

 the species seems to be limited to tropical 

 or subtropical waters.
