with about twelve remote and somewhat undulate laminar rido-es. 

 and close-set raised rib-like-striae between them, nnd which lon- 

 gitudinal striae are themselves crossed by fine transverse lines, 

 especially towards the beaks, where it slopes ou the anterior side 

 in a rather projecting curved line : the area is equally deep on 

 both sides, and with the areola of a chesnut color. 



It has something the outline of the Venus cancellata; but the 

 ridges are more remote and less numerous; there is no angu- 

 larity on the anterior side, but a regular slope; and it may be 

 distinguished from that shell and the Venus lauiinosa, by the 

 regular rib-like semicircular striae on the areola, which is heart- 

 shaped.
