The species is characterized by a large, trochiform shell; color ranging from intense reddish to white (darker on spiral cords, lighter at base) with a yellow apex; sculpture of 3-8 wide spiral cords with large scale-like spines; cords separated by deep interspaces with similar width, and interspaces sculptured by closely-packed, thin axial growth lines.
