Orif/hicd description: — "Shell moderately uinbilicated, turbinate, 

 rather thin, pale horny, with liue subdi.staut plicate costuhition ou 

 the upper part of the \^horls near the suture, smoother below, 

 finely and closely ribbed on the swollen portion of the last whorl. 

 Spire couoidal, apex rather acute, suture well impressed. Whorls 

 4, rounded, the last moderately swollen at the side, ne.xt con- 

 stricted and smooth for a short distance, then traversed by a 

 slightly recurved ridge, more developed in some specimens than 

 in others, with a nearly smooth interval behind the mouth, but 

 gradually becoming impressed with longitudinal undulations near 

 the peristome. Sutural tube moderate. Aperture diagonal, 

 waved on the outer and upper margins. Peristome thickened, 

 irregularly double, expanding with 4 or 5 undulations on the 

 right side, extending from the point of junction with the last 

 whorl to the base of the aperture ; the inner salient angles 

 strongly projecting in aged specimens. Operculum multispiral, 

 thickened, convex behind, very concave in front.

 whitish ; spire low, apex blunt ; suture moderately impressed ; 

 whorls 4, rounded, no ridge near the constriction, expanded at the 

 aperture forward, forming a notch near the inner upper side 

 which is conspicuous ; aperture ovate ; peristome double, broad,
