Description

The size of the adult shell varies between 20 mm and 26 mm. The notably thick, solid shell has a rather conical shape. It is, transversely sulcate. It has a pale green ground, painted with close purple-red streaks above. The base has red-spotted girdles. The whorls are a little subangular above the suture and a little plicate below the sutures, appearing somewhat terraced. The body whorl is rounded-angulate and passes into the base with a blunt angle. The sculpture consists of about 7 weak smooth transverse grooves on the upper surface, and about 4 scarcely elevated concentric girdles on the base. The base of the shell is nearly plane, obsoletely cingulate and false-umbilicate. The funnel-shaped pit occupying the place of the umbilicus has a slightly elevated liration. The aperture is rhomboidal. The entirely simple columella is very oblique. [3]

Distribution

This marine species occurs in the Persian Gulf.
