spiral bands of white : with, on each whorl, about thirty narrow 

 prominent transverse ridges more or less inequidistant ; with 

 numerous raised spiral lines, of which five are seen on the spire, 

 and which on the last whorl are less prominent and wide than 

 the transverse ridges : apex subacute : spire with the outlines 

 nearly rectilinear : whorls six, convex, with the suture subca- 

 naliculate ; last whorl rather large : aperture semiobovate, with 

 long sharp ridges within on the right side : labrum sharp, 

 thickened a little behind the edge, scalloped by both the inter- 

 nal and the external sculpture: columella stout, with three 

 plaits, of which the upper one is lamelliform and very promi- 

 nent, and the lower one is small and very oblique : canal short : 

 with a small umbilical chink bounded by the raised labrum and 

 a spiral bridge.
