Class: Gastropoda

Size: 47 mm.

Color: Chestnut-brown to blackish-brown in color, ornamented with narrow, wavy white axial stripes which are usually interrupted centrally or may be continuous, and are broken up into small spots towards the base, in some individuals the axial stripes are replaced by a narrow or broad, faint or distinct, orange-brown or white subsutural band, while a few rare individuals lack all kinds of ornamentation. Aperture and columellar folds white or bluish-white, occasionally Periostracum thin, brown and translucent.

Shell about 2 inches in length, heavey and solid, elongate-ovate and often inflated, sutures distinct but narrowly incised. Whorls 6-7, apart from a protoconch of 2 light brown, smooth nuclear whorls, spire whorls distinctly convex, last whorl usually inflated, sculptured with narrowly incised spiral grooves which usually produce feebly elevated cords which number from 2-8 on the penultimate and from 5-15 on the body whorl, in most specimens, however, the body whorl has only up to half a dozen spiral threads at the shoulder, the centre of the whorl is smooth and the lower third has oblique spiral cords. Under magnification very fine axial striae are visible. Aperture usually longer than the spire, moderately wide and smooth within, outer lip convex or sometimes subangulate anteriorly and weakly constricted posteriorly, interior callus weak in most specimens, margin of outer lip thickened and smooth, or with weak traces of a few denticles anteriorly. Columella calloused anteriorly, and with 4-5 prominent, oblique folds, parietal wall only glazed but posteriorly with a small white callus pad in adult specimens, siphonal fasciole straight, occasionally weakly calloused, siphonal notch very prominent.
