 spire obtusely conical ; whorls 5, slightly convex, the last rather in- 

 flated, descending in front, a little contracted behind the aperture ; 

 aperture very oblique, ovate, purplish brown within ; peristome not 

 thickened, widely expanded, the margins approximating, joined by a

 rapidly increasing, last very large, inflated below ; aperture nearly 

 diagonal, irregularly roundly lunate ; margins slightly approach-
