Shell ovate-inflated. Spire involute. Aperture narrow, cancellate ornamentation very fine and consisting of numerous equidistant spiral ribs (about 23) crossed by longitudinal ribs. Spiral ribs tend to alternate in strength on central part of base of shell and tend to become stronger than longitudinal ribs on anterior part of base of shell. Outer lip prominent, especially its pos- terior end. (
