Description. Shell elongately ovate, concentrically striate; buccal side rounded; anal 

 side acute, somewhat rostrate. 



This neat species is easily distinguished from its congeners of this formation, by the 

 greater regularity of the striae, and by its more elongated anal side. 



It is a rare species in the Pleiocene of South-Carolina, although abundant in the living 

 fauna of the coast.
