The shell is rather small, ovate, thick and globular. Its color is of an ash-white. The spire is conical and, pointed, composed of six whorls, the lowest much larger than all the other. This body whorl presents on its surface conical, distant tubercles, disposed in four series. A few transverse striae ornament the base. The upper whorls have only a single row of tubercles. The ovate aperture is narrow, emarginated at the upper part, at its union with the outer lip, which is thick, striated internally. The columella is arcuated, covering the inner lip, which is expanded into a white, thick callosity, covering the whole lower surface, and a portion of the upper whorls.[2] DistributionThe shell occurs in the Indo-West Pacific Ocean off Réunion, Aldabra, Chagos, Mascarene Basin. Specimens of this species were gathered by Rizal in Dapitan in 1894[3] although he labeled them as Nassa arcularia; also off many islands in Oceania and off Australia (New South Wales, Northern Territory, Queensland).
