This species is remarkable for the granular aspect of the 

 third whorl. Between tlie ribs, which are white and scarcely 

 reach to the suture above, it is of a pale olive-brown colour ; 

 the Cauda also is white, and a narrow white stripe encircles 

 the last whorl, interrupting the olive-brown colour of the 

 interstices.
