Shell short, stout, white, with five or more whorls; apex eroded ; the last two whorls show about fifteen short, stout, transverse ribs, which do not reach the suture and become obsolete a little in front of the periphery; they arc most prominent at the shoulder of the whorl; behind them there is a moderate constriction and the whorl is strongly appressed in front of the suture; beside the ribs, the transverse sculpture consists of irregular, strong, incremental lines; spiral sculpture of numerous coarse, close-set, rounded threads, mostly alternating larger and smaller or more and less prominent near the suture; these are a little granulated by the incremental lines; there is a thin, pale yellow, hispid epidermis; aperture elongate, outer lip slightly thickened with a band of livid pink just inside the sharp simple margin; body and pillar with a solid, also slightly pinkish, callus; pillar a little tortuous, attenuated in front ; canal rather short and wide, somewhat recurved, not well differentiated from the rest of the aperture. Maximum longitude of (decollate) shell, 30; of last whorl, 22.5 mm; of aperture, 18 mm; diameter, 15mm.
