Description

The shell size varies between 7 mm and 20 mm. The very solid, thick, narrowly perforated shell has a conical shape and is elevated. It is ashen-white, with longitudinal chestnut streaks or maculations. The spire is elevated. The apex is acute. The sutures are slightly impressed, the whorl below them closely appressed. The shell contains 6 to 7 whorls. The upper ones are subangular and nodulose in the middle. The body whorl shows a coronal series of knobs, on large specimens becoming obsolete toward the aperture. The entire surface is traversed by spiral lirulae, much narrower than the densely obliquely striate interstices. The oblique, ovate aperture is about half the length of shell. The outer lip is bevelled to an edge. The aperture is spirally lirate. The edge of the columella is denticulate. Its upper insertion is callous, partly or nearly covering the umbilicus. Young specimens are subbiangulate with nodulose periphery. [3]

Distribution

This species is distributed in the Red Sea and in the Indian Ocean off Madagascar, Mozambique, Tanzania and Durban, South Africa.
