(original description) the small shell has an elongate and subfusiform shape. it is dark purplish brown, paler at the apex. it contains 6½ whorls, divided by a deep suture ; the first 1½ forming the protoconch, large, semiglobose and smooth. the rest are slightly convex and longitudinally ribbed. the ribs are stout, broader than the interstices, suberect, a little arcuated. those on the body whorl become obsolete a trifle below the middle, whence downward the whorl is transversely finely striated, the striae at the extremity being closer together than those above. the aperture is small, ovate, occupying about one third of the entire length. the columella is arcuate, covered with a thin callosity. the outer lip is thickened, with a very faint sinus a little below the suture. the siphonal canal is short, distinct and oblique.
