Shell large, regularly conical with a flat base and an acute peripheral angle, nearly as high as broad. Whorls covered with a sculpture of poorly defined spiral cords, more or less beaded and crossed by oblique axial folds running from the suture to mid-whorl. Umbilicus broad and deep, with the columella reaching inside. Columella sinuous, but not bearing a definite tooth.

This species cannot be mistaken for any Mediterranean native. The real Trochus kochi Philippi, 1844, a related species from Southern Arabia, has a lower profile, distinct tooth on the columella and lacks the color bands around the umbilicus.
