AldricJi' s original description. — "Shell broadly fusiform; whorls 

 six — nucleus composed of two smooth whorls, those remaining 

 covered with revolving, somewhat alternating raised lines and 

 strong longitudinal ribs, which give the shell an angular ap- 

 pearance. Outer lip sinuate, thickened internally, finely crenat- 

 ed; columella bearing two erect, strong folds, the posterior one 

 nearly twice as large as the other, below these folds nearly 

 straight.

Not having any good specimen of this species we have copied

 lines.
