Shell rather thin, of a greenish-horn color, coarsely sculptured, somewhat shining. Spire convex, not much elevated, obtuse. Whorls 5, convex, furnished with broad, distant and irregular ribs, closer and more regular on the under side, but never obsolete. Suture furnished with an appressed keel, canaliculate above. Body whorl briefly, but not abruptly falling in front, convex above the inserted keel, more so below, the keel somewhat irregular, margined on both sides, especially above where the impressed line is very conspicuous. Umbilicus medium-sized. Aperture oblique, transversely oval, livid within, scarcely angular internally, barely lunate. Peristome white, moderately thickened, expanded, reflected below, chiefly towards the umbilicus. Margins not remote, connected by a thin shining callosity.
