Shape biconic-fusiform, b/1 0.26-0.31, a/1 0.40-0.43, spire angle 29°-32°, whorls moderately convex with peripheral cord forming a slight angle at or below midwhorl; aperture slightly deltoid in shape, siphonal canal more or less equal to aperture, rostrum slightly recurved, with a narrow but distinct fasciole, sometimes with a very slight false umbilicus. Outer lip in side view convex (slightly opisthocline), with a distinct stromboid notch, edge of lip fluted; siphonal canal moderately shallow, linear, expanding at edge. Surface smooth and glossy, spiral cords low, in t/s weakly and gradually rounded to broadly and weakly angular, intervals shallow; suture shallow. Subsutural cord strongly impressed, weakly rounded, with a very slight median ridge; sinus cord narrow, medially sunken. Peripheral cord weakly projecting, very slightly angular, base of whorl with a similar but weaker and narrower cord, bordered above and below by a fine intermediary thread. Upper part of base with three low, weakly defined cords, with a finer intermediary between each pair; rostrum with 5-6 fine ridges, becoming obsolete towards termination. Early whorls with the subsutural cord distinctly bifid, peripheral cord angular. Porcellaneous white to pale brown, main spiral cords with conspicuous rounded or rectangular black or brownish-black spots with white intervals, subsutural region and a broad interrupted band around upper part of base with a dark to reddish-brown suffusion, intervals between cords sometimes similarly brown; aperture and inner lip white. Attains ca 95.5 mm in length.
