Gibbula zonata is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.[1]
The size of the shell varies between 6 mm and 10 mm. The rather solid shell is imperforate but excavated at the place of the umbilicus. It has a depressed-conical shape. It is whitish, with numerous spiral bauds and lines of purplish-brown. The surface is very lightly obliquely striate, closely, densely finely spirally striate, generally with three strong carinae, one at periphery, the others above. The about 5 whorls are convex, those of the upper surface bicarinate. The convex body whorl is carinate or subcarinate. The oblique aperture is rounded-quadrangular. It is nacreous inside with slight sulci at the positions of the external carina. The columella is a little straightened.[2]
This species occurs in the Atlantic Ocean off Namibia and the western coast of South Africa; in the Indian Ocean off the Agulhas Bank.
