 striolated. Whorls six or seven, short, a little rounded, 

 well-defined ; body about equal to one-third the entire 

 length ; apex blunt. Aperture small, nearly semicircular, 

 with generally a small tubercular denticle (there exists an 

 edentulous variety) deeply seated on the body whorl, about 

 half way between the coluraellar and the outer lip. Peri- 

 stome scarcely reflected ; outer lip not denticulated, simple, 

 margined externally by a strong white rounded callus or rib. 

 Pillar lip somewhat reflected, with a small subumbilicus 

 lying behind it. Columella for the most part shorter than 

 the inner wall of the aperture.

 black upon the neck, head, and upper tentacles, darker
