Shell conically ovate, solid; 6 whorls, flatly convex, with decus- 
sating strie; columella strongly callous; suture plain, moderately 
impressed ; umbilicus small and open ; lip expanded, and subreflected 
below; ground colour brownish red, covered with an epidermis of a

in fine zigzag markings, which are lost on the last whorl in a uni-

This is a very rare species, the numbers found scarcely furnishing 
the materials for a description to fix or determine the permanent 
characters.
