Shell fusiform, with a total of 6 whorls, thin and translucent, surface very smooth and glossy, lacking sculpture of any kind. Spire high, spire height to total shell height ratio 0.41. Protoconch smooth, opaque, glassy, calloused, slightly deviated, broad and dome-shaped, not sharply differentiated from teleoconch so that number of protoconch whorls is not determinable. Second whorl with a diagonal flaw resembling a suture line. Coiling normal except for a difference of about 15° between the suture slopes of the first-second and second-third whorls. Whorls convex, lacking shoulders, sutures weakly incised. Outer lip convex, slightly flared out anteriorly, columellar and parietal walls gently curved, aperture widens anteriorly. Columella weak, not calloused, bearing 4 oblique plaits of which the central two are moderately strong, straight sided and flat topped, the posterior one is weak and bifid, and the anterior one is moderately strong and forms the almost axial lip of the anterior part of the columella. Anterior canal broad, moderately deep; anterior fasciole weak. Early whorls cream merging into fawn to apricot on the later whorls. Body whorl with a wide pale central spiral band bordered by two poorly defined thick white spiral lines on each side, and with another thick white spiral line below the suture. Small regularly spaced orange-brown rings enclosing pale orange spots lie on the two central white lines; confluent orange brown blotches lie on the subsutural line. The most posterior of the central lines and its rings are evident above the sutures of the 4th and 5th whorls. Columellar teeth white, anterior fasciole off-white, lip margin white, interior takes the colour of the exterior although the spiral lines and rings do not show through. Measurements: total shell height 53.4 mm, spire height 21.9 mm, width 20.2 mm.
