Whorls convex to (sub)cylindrical, shouldered, sometimes with strong keel at shoulder. Shell sculpture pronounced in most cases, spiral sculpture from microscopic threads to prominent keels; axial sculpture, when present, of distinct, broad, sigmoid or arcuated axial ribs. Shell covered with ciliated periostracum, sometimes thick and forming lamellae. Aperture wide, ovate with simple outer lip. Operculum small to large, with subcentral nucleus. Radula with central tooth with broad rectangular base, notched anteriorly, and with nearly straight posterior margin with three to eight cusps; lateral teeth with three to four cusps, intermediate one much shorter than outer and inner ones (after Kantor et al. 2022).
