Shell widely umbilicated, depressed, transparent, shining, white, with a greenish tinge, marked with distinct and regular striae of growth and micro- scopic revolving lines, the latter more conspicuous below; spire but slightly elevated; whorls 3, rounded, rapidly increasing, the last planulate above, widely umbilicated below; aper- ture very oblique, subcircular, remote from the axis; peristome simple, acute, its terminations somewhat approached, that of the columella not reflected.
