Shell up to 50 mm (2 inches) in length, fusiformly-elongate, body whorl slightly inflated, solid, sutures narrowly ledged and finely crenate. Whorls 8-9 inclusive of a worn protoconch, first 3-4 post-nuclear whorls flat-sided and last 3 whorls convex, sculptured with slender and rounded axial riblets which number from 25-30 on the penultimate and from 30-45 on the body whorl, riblets rendered granulose through bisecting and moderately deep spiral grooves; grooves number from 6-9 on the penultimate and from 17-20 on the body whorl, apart from about a dozen oblique spiral cords at the base. The axial riblets are not all of equal strength, some being lower and others more elevated, and protrude for a short distance over the sutures. Aperture almost equal in height to the spire, narrow and elongate, smooth within, outer lip weakly convex and constricted basally, moderately thickened and presumably bluntly crenulate by the spiral cords. Columella calloused, callus slightly more prominent anteriorly, and with 5-6 strong, oblique folds; siphonal fasciole moderately slender, slightly produced and only weakly recurved, siphonal notch distinct White in colour, ornamented with dark orange blotches which are arranged transversely, and form 2 bands on the spire whorls and 3 on the body whorl; the blotches next to the sutures are larger than remaining blotches, aperture and columella cream to light yellow, columel-lar folds cream or white.
