Color rich reddish brown, with longitudinal zigzag white markings; sometimes the white predominates and the bands are brown. There is a row of very dark spots above the suture and on the middle of the body whorl, which often lias alternating white spots, though it is sometimes wanting; sometimes there are two such bands on the body whorl. There is often a row of large white blotches below the suture; aperture white.
