Spirals fine, close together, becoming a little more prominent on canal. Aperture broad, with four plaits uppermost very weak. Middle two strongest, lowest rather weak. Canal twisted to left and behind, broadly open and rather long.

The generic and subgeneric placing of this species is only tentative as comparative material and radula data are lacking.”
