[1] It is found in tropical and subtropical coastal waters across the world, inhabiting muddy areas close to the shoreline.

This body whorl is very much inflated, and furnished externally with thick, longitudinal, distant folds, which are intersected by transverse striae.

The upper extremity of each fold is terminated by a conical tubercle, sometimes separated from it by a transverse stria which divides it superficially into two.

The columella is arcuated, covered by the inner lip, which is enlarged upon the body of the shell, and forms a semicircular callosity, often thick, polished, marked at the lower part by transverse guttules, and terminated by an oblique keel, which is prolonged to a point.

[3] This species occurs in the Indian Ocean off East Africa, Madagascar and Mozambique and in the Central and Western Pacific Ocean; off East India, Sri Lanka, the Philippines, Indonesia, Ryukyu Islands, Papua New Guinea, New Caledonia, New Hebrides, Fiji, Tonga Islands and Australia (Northern Territory, Queensland).
