TELLINA TENTA. 



SPECIFIC CHARACTER. 



Rostrum curved to the left; no lateral teeth. 



DESCRIPTION. 



Shell transversely oblong-ovate, fragile, a little com- 

 pressed, white, with a tinge of dull yellowish towards the 

 umbones; wrinkles of growth not very prominent, but 

 more obvious on the anterior side; beaks a little before 

 the middle, not much elevated; anterior side narrowed, 

 curved to the left, at tip truncated or obviously emargi- 

 nate; umbonial slope hardly elevated; within with an 

 obsolete appearance of radiating lines; lateral teeth none; 

 cardinal teeth in the left valve prominent; a tinge of dull 

 yellowish on the disk as on the exterior. 



OBSERVATIONS. 



Inhabits the coast of South Carolina. — Dr. Raucnel. 



The proportion of length and breadth is nearly that 

 of TcUina nitida, Poli, but the beaks are rather more 

 anterior. The anterior side is a little more obtuse than 

 that of T. pu/r/iclla, Lam., and a little more curved to 

 the left nearer the tip. It evidently resembles T. dcprcssn^ 

 Gmelin, but I cannot perceive any lateral tooth.
