Shell large, broad, and comparatively thin, conic-fusiform, contracted at the base, turreted, last whorl about as long as the spire. Whorls eight, including the protoconch, which is mucronate of two whorls, the first fiat-topped, the next keeled. Suture canaliculate. Colour buff, finely speckled with chestnut, the spots larger and darker near the suture, with a pale zone below the periphery. Sculpture: the ribs are low, round-backed, sharply angled at the shoulder, vanishing on the base and round the fasciole area, spaced at twelve to a whorl; the whole shell is wrapped in sharp narrow threads, which swell on crossing a rib and shrink in the interval; they are parted by furrows deeper than wide, and support microscopic close-set transverse beads; on the penultimate there are about twenty-three and on the last whorl about sixty of these cords. Aperture : the variceal ridge is tall and narrow, from which extends squarely a free limb dentate at the edge and slightly ribbed within; sinus rather deep and C-shaped; a callus tubercle at the right insertion is tricuspid ; on the inner lip the callous sheet thins off to a fine edge, and has a few faint plications anteriorly; canal short, broad, and recurved. Length 17 mm., breadth 7,5 mm.
