Description
A robust, medium-sized marine gastropod shell, characterized by its fusiform shape and prominent, often spiny or frilly axial varices. The shell exhibits a light, off-white to cream coloration, with subtle hints of reddish-brown or orange-brown markings, particularly on the spiral ridges between the varices. The siphonal canal is relatively long and distinct.
