Description
A robust, high-spired, conical marine gastropod shell, predominantly off-white to cream in color. It features distinct, somewhat stepped whorls and a prominent, though relatively smooth, keel at the periphery. The apex is acute, and the shell appears thick and solid, often showing signs of natural discoloration or encrustations.
