 brown, or chestnut coloured, not much shining, indistinctly 

 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 columcllar 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. 



Length the ninth of an inch ; breadth about half a line. 

 The species is recognised as the original Turbo muscorum 

 by an examination of specimens in the Lininean cabinet. 



The animal is slenderer than the last, very dark blue 

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