smooth, thin, transhicent; aperture comparatively short, narrow, 

 nearly in the line of the elongate axis, supplementary aperture very 

 inconspicuous. Length, 0.50 mm.; diameter, 0.24 mm. 



Brady's types of this species were from Challenger station 120, off 

 Pernambuco, Brazil. It has been recorded from the Indo-Pacific 

 and Australian regions. We have a typical specimen from 98 fathoms, 

 off the Big King, New Zealand, and one specimen from off the Philip- 

 pines. It is interesting, therefore, to find that in our Pacific material 

 this species is comparatively rare, occurring almost entirely at the 

 deeper Albatross stations and found only once at Rutavu in the 

 shallow-water samples and then only as a single specimen.
