Zonites

Zonites is a genus of mostly small, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Zonitidae.

The genus Zonites, which includes 26 extant species, is distributed in the northeastern Mediterranean area and exhibits significant diversity and endemism.

Description
The shell of species in this genus is more or less transparent, subdepressed and contains an umbilicus. The aperture is semilunar and usually lacks teeth. The outer lip is thin and sharp.

The animal is elongate and is able to retract completely within its shell. It has a more or less developed caudal mucous pit. The mantle lobes are small and not reflected on to the shell. The genital orifice is somewhat distant from the right tentacle. The jaw is marked by a median rostrum. The lateral teeth of the radula are bicuspidate, while the marginal teeth are sharp and narrowly unicuspidate.
