Shell of Gibberulus gibberulus (Index Testarum Conchyliorum (1742) of Niccolò Gualtieri)
The adult shell size varies between 30 mm and 70 mm. The smooth shell is gibbous. The
spire is occasionally varicose. The
body whorl is grooved at the base. The
columella is smooth. The interior of the
aperture is radiately striate. The shell is mottled and hieroglyphically marked with yellowish brown and white. The markings are often arranged in a few or numerous interrupted revolving bands. The aperture is tinged violaceous, scarlet or dark purplish brown.[2]
