Description
editThe shell size varies between 11 mm and 18 mm
The small shell is pretty thin, ovate, conical and smooth. It is of a diaphanous white. The sutures are indistinctly apparent. The spire is composed of six convex whorls, ornamented at their base with spots of a duller white. The body whorl is as large as all the others, striated at base, and surrounded, towards the middle, with small, distant spots, articulated by a reddish line. The aperture is ovate. The outer lip denticulated within, and thickened outwardly, even to the base of the shell.[2]
Distribution
editThis species occurs in the Indian Ocean off East Africa and Mauritius and Réunion and in the Indo-West Pacific; off Australia (Queensland)
