Shell low turbiniform, sinistral with flattened apex seemingly attached to a slender bryozoan branch. Protoconch heterostrophic, consisting of two whorls on which no microsculpture can be observed. Teleoconch whorls expanding slowly, flattened on adapical side, becoming more convex on lateral and abapical side. Adapical side of whorls with strong transverse ribs curving from the adapical suture and backwards into an initially indistinct, but progressively deeper sinus situated halfway between sutures; transverse ribs continue forward and down to the periphery of the last whorl, where they are replaced rather abruptly by seven moderately coarse spiral ribs. Transverse rib number per half-whorl approximating 15 on third whorl.
