perforate except about the aperture where it is apparently without 

 perforations; aperture loop-shaped, placed well above the junction of 

 the second and third chambers. Length, 0.25 mm.; diameter, 

 0.15 mm. 



This small species seems to be very distinct but limited in its dis- 

 tribution, as it has occurred only at the type station, 12 fathoms, 

 Nairai, Fiji, and at Levuka, Fiji, also in 12 fathoms.
