Description. Shell sub-conical, smooth, milky-white, sometimes almost transparent; 

 whorls nine to twelve ; suture slightly defined ; in some specimens a bluish or brown 

 band revolves below the sutures; aperture somewhat oblique, ovate-acute. 



This is a variable shell, abundant in the Post-Pleiocene of South-Carolina, and accord- 

 ing to Mr. Conrad, found in the Meiocene of Suffolk, Virginia. It is recent on the 

 Atlantic coast, from Buzzard's bay southward. E. conotdea, E. l^vigata and E. 

 OLEACEA are to our mind one and the same species.

Description. Shell subulate, smooth, angularly channeled at the suture, Avhich is 

 crenulated on the lower whorls only ; coluraellar with three folds, the superior one large 

 and acute, the others small; outer lip with four small teeth internally; whorls fourteen to 

 sixteen ; with two indistinct opaque revolving bands, which are sometimes obsolete. 



This shell is readily distinguished from its congener, O. arenosa, of the Pleiocene, by 

 having only the lower edge of the suture crenulated, one more fold and tooth, and opaque 

 revolving bands. 



This species, and not O. arenosa, is now living on tlie coast of South-Carolina.
