Description

The size of the shell varies between 10 mm and 18 mm, the diameter is up to 13 mm. The narrowly perforate shell has a conic-acute shape. The 9 to 10 whorls are planulate. The embryonic whorls are smooth, buff, the remaining whitish-buff. The whorls are ornamented with longitudinal wavy streaks of brown or rosy, and sometimes spiral zones. They are spirally lirate with 7 lirae on the penultimate whorl, upper and lower ones most prominent, the intermediate 5 slightly granose. The interstices are sharply obliquely striate. The body whorl is angular, convex beneath and contains about 8 concentric lirae. The aperture subquadrate. The lip is acute. The columella is subtruncate. The parietal wall bears a callus in adults. ^[2]

This marine species occurs in Madagascar. ^[1]
