Description
Color: The colour of the shells varies from white with brownish black tint on
the nodules and adjacent ribs to light brown with sooty brown pigmentation over most of the surface of the shell.

The shell is highly variable in sculpture. It is rather small, with widely inflated aperture, about 50 per cent of shell length. The keel is wide and bears the characteristic 15 to 23 prominent, large and blunt nodules placed in pairs over the keel. Great variations exist in size and form of the nodules. The ribs on the sides of the shell extending from the crainal knobs are less numerous when compared to the other species with less bifurcation. There are two types of ribs present, the long and full sized ribs extending from the nodules to the nucleus which are in regular alternating series with the secondary ones; the latter are short and extend upto half way from the nodules.
