TELLINA BREVIFRONS. 



SPECIFIC CHARACTER. 



Ovate, white, tinged with yellowish; anterior side very 

 short. 



DESCRIPTION. 



Shell thin and fragile, not very convex, white, tinged, 

 particularly on the umbo, with pale dull fulvous; with 

 transverse slender stria3, and in a particular light obsolete 

 longitudinal striae are visible; beaks much anterior to the 

 middle, forming an angle in consequence of the anterior 

 and posterior hinge margins being rectilinear to a con- 

 siderable distance, the latter parallel to the base; anterior 

 side short and abrupt, rounded at tip, and with a sub- 

 marginal undulation; posterior side more than as long 

 again as the anterior, rounded at tip; within much more 

 deeply coloured with fulvous; cardinal teeth, two in the 

 left valve and one in the rii>;ht valve; lateral teeth none. 



OBSERVATIONS. 



Inhabits the coast of South Carolina. 



The outline of this shell corresponds with T. donaciiia^ 

 Lin., but it is more convex, and not radiated with reddish. 

 Dr. Ravenel informs me that it is very rare. He obtained 

 but a single specimen, which he obligingly sent me for 

 examination. It also resembles T. decora^ Say, and may 

 readily be mistaken for it, but is altogether destitute of 

 oblique stria? and rosaceous radiations.
