 T. testa tenui, albesceute; valvis cymbseformibus, prof undo 



convexis, umbonibus parvis, antice obliquis, contiguis, superficie 

 in medio depressa, utriaque lobata, prsecipue marginem apud

The ventrally depressed surface of the valves of this little 

 species are very peculiar, and they are also extremely convex, the 

 umbones contiguous, inclining anteriorly ; within, the margins 

 are microscopically longitudinally striate. The nearest all}- 

 would seem to be T. triangularis, (xould.
