The spire is plano-depressed, ornamented thickly with spiral sub-obsolete ribs and longitudinal lirae, with two nodose keels at the periphery. The nodes in the second whorl are raised and imbricated. The nodes on the upper carina become little raised hollow rounded squamae on the second whorl.The aperture has a reflexed and thickened margin. The umbilicus is very wide and spirally dentate. This shell is nacreous within.〔(Tenison-Woods, J.E. 1876. On some new Tasmanian marine shells. Papers and Proceedings of the Royal Society of Tasmania 1876: 131-159 )〕
