Shell small, stout, short-fusiform, white, flecked or clouded on the prominences of the sculpture with pale yellow-brown; whorls about five, nucleus white, blunt, polished; later whorls with, between the sutures, four subequal spiral nodulous cords with deep narrower interspaces, the cord in front of the suture slightly more prominent than the others; on the last whorl there are about fifteen spiral cords which are crossed by about twenty axial, incised, equally spaced lines, the segments of the cords thus formed being convexly nodulous; toward the aperture the axial lines become feebler or obsolete; aperture short and rather narrow with about six spiral lirations inside the outer lip which is simple and not reflected and hardly thickened; on the pillar are two strong plaits, rather deep within the aperture; the canal is short and not very deep, with hardly any siphonal fasciole. Length of shell, 4.7; of last whorl, 3.5; of aperture, 2.5; maximum diameter of shell, 2.5 mm.
