Gibbula is a genus of small sea snails, marine gastropod molluscs in the family Trochidae, the top snails.[2]

Distribution

The species in this genus occur through all seas, except on the coast of the American continent.

Description

The cyrtoconoid (= approaching a conical shape but with convex sides) shell is usually perforate or umbilicate. The spire is moderately elevated. The whorls are often gibbous or tuberculose beneath the sutures, smooth or spirally ribbed. The last whorl is generally angular at the periphery. The aperture is subrhomboidal. The columella is oblique, dentate or subsinuous at the base. The outer lip is acute. The central tooth and the lateral teeth of the radula have well-developed denticulate cusps.The outer lateral teeth are wider.[3]
