Remarks.

This is a new record for Penang Hill. The shell is convex discus-shaped. The shell periphery is angular with a spiral thread. Above the shell, the apical whorls have shallow spiral ribs crossed by growth lines, transitioning to regularly placed prominent radial ribs on the subsequent whorls. Below the shell, radial ribs continue from above at the periphery, transitioning to spaced spiral grooves which reduce towards the umbilicus.
