The whorls are encircled with a series of rather acute and pro- 

 minent nodules, formed by the hind portions of the longitudinal 

 plicae, which, in this species, are rather indistinct ; the surface of 

 the shell is pitted in a peculiar manner, and the whorls are 

 adorned with rows of square brown spots, forming three zones on 

 the last whorl,
