"Shell broadly elongate-conic, dark chocolate brown. Nu- 

 clear whorls 3, smooth, well rounded, separated by a slender su-

 wide as the spaces that separate them. Of these, the 1st and 

 widest is at the summit, the next is median, while the 3d is a lit-

 The tubercles at the summit are well rounded anteriorly and pos-
