Shell an elongate cone, narrow in proportion to length, thick and strong, anteriorly broad and blunt, posteriorly tapering slowly, scarcely perforate. Colour pale ochre, with a darker broad peripheral band, which is edged above and below with a pale border, and a narrow, dull white margin below the suture. Whorls six, rounded, apex blunt, nepionic shell a whorl and a half.Suture impressed. Sculpture;—everywhere irregularly crossed by oblique growth lines, both fine and coarse, which interrupt and distort a series of minute, numerous, irregular, spiral scratches which are not to be perceived without a lens. Aperture oblique, rudely hexagonal, subchannelled anteriorly. Columella thickened, externally folded over a narrow umbilical chink, internally sharply bent, the upper limb a flat, deeply entering and obliquely ascending plate, the lower swelling into a slight but distinct tubercle. Outer lip internally much thickened, but neither thickened nor reflected externally, forming a sharp angle at the insertion. A thin callus is spread on the body whorl. In the specimen described the anterior corner of the aperture is externally surrounded by a series of imbricating lamellae; this may, however, be an individual feature or repair of breakage. Length 26, breadth 12 mm.
