Test elongate, the adult with three visible chambers, the last- 

 formed chamber broadest near the initial end and longer than the 

 preceding ones ; test in end view triangular, the sides broadly curved 

 and angles rounded; chambers inflated; sutures distinct, depressed; 

 wall smooth and usually polished; aperture oval with the tooth 

 simple or narrow, and bifid at the tip. Length, 0.7-1 mm. ; breadth, 

 0.4-0.55 mm. ; thickness, 0.25-0.35 mm.

It is very evident that more than one species is included in the 

 various references to Montagu's oblonga. The apertural features 

 show specimens with an elongate, either simple or bifid tooth, to- 

 gether with a somewhat similar form with a flattened tooth nearly 

 filling the aperture. In this South Pacific collection we have lim- 

 ited this species to those forms which have the narrow tooth.
