 larger than the penultimate, and the latter larger than the body-

 sides inflated. The last whorl is small, attenuated, and slightly 

 ascending. The aperture is subcircular, and the peristome is slightly

A sinistral, ovate, pale-yellowish species, with crowded costulate 

 striae and convexly conical spire. Whorls 5, rapidly increasing, 

 convex, the fourth one subinflated, the penultimate swollen on the 

 back and retracted on the front, the last one attenuated, compressed 

 at the base, and rapidly ascending. The subquadrate aperture is
