The excavated area behind the umboes, and the ab- 
sence of strix, distinguish the shell from Tellina striata.

It differs in coarseness of sculpture from Tellina 
Remus.

Hab. Australia, 
This shell, of which there is only a single valve 
in the late Mr. Cuming’s collection, might pass for 
a white specimen of Tellina pulcherrima, if the 
laminez were not confined to the region of the 
umboes.
