The shell is yellowish in color, with purplish-brown flame-like markings around the periphery and obscure dotting. The base has somewhat smooth ridges with dotted, jewel-like patterns, is flat and slightly convex. The columella is calloused, and the interior of the aperture is smoothly striated.^[2]
