Description: Whorls concave above periphery, convex below, sculptured with oblique axial ribs, about 14 on penultimate whorl, occupying two thirds of height of each whorl. Spiral sculpture absent to naked eye, microscopically visible as fine threads, about 30 per whorl. Inner lip of aperture with large callous pad at upper end in mature shells; outer lip with rounded V shaped sinus with apex between periphery and suture. Colour cream to dark brown, darker specimens with a cream spiral band below the suture and at base of body whorl.
Size: Up to 24 mm in length.
Distribution: Endemic to Australia; Yamba to Sydney, NSW.
