Shell very minute, bluish white; transparent; not falcate. Whorls almost flattened; appressed at the summit, through which the preceding whorl shines, which lends the shell the aspect of having a double suture. Suture scarcely perceptible. Periphery of the last whorl well rounded. Base moderately long, well rounded; entire surface of spire and base marked by exceedingly fine, incremental lines. No varicial markings arc apparent on any of our shells. Aperture oval, posterior angle acute; outer lip clavate; inner lip short, curved, slightly reflected; parietal wall covered by a moderately thick callus.
