Description
A medium-sized, robust marine gastropod shell, characterized by its globose-ovate shape and strong sculpture. The exterior displays a complex pattern of spiral cords and axial ribs, often forming nodules or a cancellate texture. Its coloration is typically a mottled brownish-grey with distinctive white or pale spots arranged in spiral bands, creating a checkered appearance. The interior of the aperture is a striking feature, often a vibrant bluish-white or pale blue, contrasting with a dark brown or orange-brown outer lip margin and sometimes internal brown streaks.
