Axial ribs fading out on lower half of body whorl. Inner lip of aperture with callous pad at upper end in mature shells; outer lip with rounded V shaped sinus with apex at centre of shoulder slope. Colour fawn, axial ribs cream." Distribution
This marine species is endemic to Australia and occurs off New South Wales (Clarence River), southernTasmania and Victoria. References
