Description The size of the mollusks shell reaches up to 15 mm in length and is light yellowish white in color.

There are no longitudinal ribs except on the upper whorls of the spire, subcontinuously three-varicose.G.W.

The uppermost whorls are strongly variced, the lower ones usually plain.J.C. Melvill (1917), A revision of the Turridae (Pleurotomidae) occurring in the Persian Gulf, Gulf of Oman and North Arabian Sea, as evidenced mostly through the results of dredgings carried out by Mr. F.
