Sliell about half an inch long, and a little more in breadth, 

 opake, of a pale brown color with sometimes, a few darker bands, 

 with numerous strong longitudinal ribs which are clothed with 

 scale-like prominences disposed transversely ; inside glossy- 

 white or flesh color, with sometimes a purple blotch in the mid- 

 dle : beaks nearly central, prominent, a little curved, with a faint 

 heart-shaped impression under them. 



This species is very singular in its genus, in having no distinct 

 area or slope on the anterior margin ; and so much resembles a 

 Cardium, that we have sometimes seen it in cabinets marked as 

 the Cardium exiguum. 



** Margine inter no integerrimo. 13-21. 

 With the inner margin very entire.
