76 POST-PLEIOCENE FOSSILS. 



below; color yellowish- white ground, with rufous, angulated lines, and zigzag marks 

 upon the surface, and revolving bands of light color. 



This is a common shell in the Post-Pleiocene, and many specimens retain their colors 

 and polish. The folds upon the inner lip are of an inconsistent character. We find them 

 more or less developed in different specimens ; some are perfectly smooth and simple on 

 the columellar, as on the labrum.

Description. Shell sub-oval, white or yellowish-white ; body-whorl with about three 

 revolving, maculated bands of pale rufous, of which the superior one is continued upon 

 the spire, the intermediate one is dilated, so as to be sometimes confluent with the inferior 

 one, which is narrowest; spire short; suture very narrow; columella destitute of 

 striae. — Say. 



This shell, though abundant in the Post-Pleiocene beds, seldom retains the colored 

 markings upon the surface. It is common in the recent state on the southern coast.
