Shell large and thick, ovate pear-shaped, ash colored ; whorls six, 

 the lowest large and capacious, broadest at its posterior fifth where 

 it is crowned by a series of compressed, triangular nodules, one at 

 each sta'ze of growth ; the spire suddenly slopes backwards from 

 these to the suture, which is well-defined, but not channelled ; the 

 spire is a low cone, pointed, the series of nodules encircling the 

 base of each whorl ; below the nodules the lower whorl gradually 

 diminishes and extends into a long, conical beak ; surface distinctly 

 marked by an elevated ridge of a darker color at each stage of 

 growth, and by revolving lines alternately larger and smaller ; ap- 

 erture long ovate, angular at its junction behind, where a canal is 

 formed by a protulierance of the opposite margin ; outer lip simple, 

 sharp, regularly curved to the extremity of the beak, or slightly
