Family of gastropods
Geomitridae is a taxonomic family of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.[1][2]
Anatomy
The family is characterized by the presence of a free right ommatophoral retractor (passing outside the peni-oviducal angle) and a double stimulatory apparatus.[1] A free right ommatophoral retractor has been linked to adaptation to xeric habitats[3]
