Shell depressed, never hispid, rather thin, and a little 

 translucent, coarsely striated lengthways, rather dull, in 

 general of a reddish horn-colour, but ranging in tint from 

 almost white to rufous brown, colouring usually disposed 

 in alternate darker and lighter shades, subcarinated upon 

 or above the middle, the angulation rendered more appa- 

 rent by being of a paler tint. Spire (in the more typical 

 form) scarcely raised ; apex not particularly blunt. 

 Whorls six, moderately convex, not abruptly enlarging ; 

 the last neither deflected above, nor sinking at its termina- 

 tion below the general level of the base. Aperture nearly 

 crescent-shaped, broader than high, about equal in breadth
