Protoconch large, gradated, of about 1.5 whorls, sculptured with 22 to 24 strong, closely arranged, axial ribs; transition to teleoconch not clearly defined. Teleoconch of up to 9.5 whorls, almost straight in outline; last whorl comprising about 25% of total shell height. Suture impressed. Surface brownish, clearest at the base and the sutures on last whorls; sculptured with 18 to 21 axial ribs per whorl and 3 prominent spiral cords, which produce large beads at their intersections. An additional, lower, smooth cord appears at the suture and delimits the base. Axial sculpture vanishing on last whorls in some specimens.
