Description
Size: 9.0 cm SHL

Color: Dirty white, suffused with pale violet. The inner surface is smooth, glossy and deep violet in color.

The shell is large in size, with a sharp, very strong, curved keel extending from the umbo down to the postero-ventral corner of the shell margin. It has a very strongly developed sculpture consisting of sharp, concentric ridges. The ridges tend to be strongly crested towards the anterior and posterior margin and are crossed by finer radial ridges, which, however, are conspicuous only in the anterior and posterior portions of the surface. The hind end of the shell is narrow and pointed, coinciding with the termination of the keel, while the anterior margin is broader and more rounded. The lunule is clearly defined and greatly elongated. The pallial sinus is broad, deep, rounded and almost horizontal.
