Faintly yellowish corneous, sparsely streaked with reddish; sculptured with fine, close, oblique rib-stria, the intervals somewhat wrinkled across. Whorls 19 to 21, slightly convex. Aperture somewhat oblique, irregularly ovate ; outer and basal margins narrowly expanded, columellar margin dilated above. Columella with two folds, the lower one bifid; parietal lamella small, penetrating about 6 whorls. Interior as in Megaspira elatior, but the scalloped columellar lamella is somewhat longer, and the basal barriers are low, and without hooks, only a few of the upper ones showing a notch at the axial end.”

Spire obtuse at apex, composed of about 19 narrow, nearly plain whorls. Aperture small, oblique, lunate, somewhat effuse at base, with a lamellar plate revolving posteriorly; columellar fold moderately developed, bilamellate. Umbilicus minute.
