Helicidae is a large, diverse family of western Palaearctic, medium to large-sized, air-breathing land snails, sometimes called the "typical snails." It includes some of the largest European land snails, several species are common in anthropogenic habitats, and some became invasive on other continents. A number of species in this family are valued as food items, including Cornu aspersum the brown or garden snail, and Helix pomatia. The biologies of these two species in particular have been thoroughly studied and documented.
Allognathus graellsianus is a species of land snail in the family Helicidae, the true snails. It is endemic to Mallorca, one of Spain's Balearic Islands. This taxa is the type species of the genus Allognathus.
Cylindrus obtusus is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Helicidae, the typical snails.
Hemicycla inutilis is a species of gastropod in the Helicidae family. It is endemic to the Canary Islands.
Hemicycla pouchet is a species of land snail in the family Helicidae.
Idiomela subplicata is a species of medium-sized air-breathing land snail, a terrestrial pulmonate gastropods in the family Helicidae, the typical snails.
Lampadia webbiana is a species of land snail in the family Helicidae, the true snails. It is endemic to the Madeira archipelago, Portugal. The species is named after botanist Philip Barker-Webb.
Leptaxis caldeirarum is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Helicidae, the typical snails.
Leptaxis terceirana is a species of land snail in the family Helicidae, the typical snails. It is endemic to the Azores.
Theba is a taxonomic genus of air-breathing land snails, medium-sized pulmonate gastropod mollusks in the family Helicidae, the true snails.
Theba pisana, common names the white garden snail, sand hill snail, white Italian snail, Mediterranean coastal snail, and simply just the Mediterranean snail, is an edible species of medium-sized, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Helicidae, the typical snails.
Eobania vermiculata also known as Helix vermiculata, common name the "chocolate-band snail" is a species of large, air-breathing, land snail, a terrestrial pulmonate gastropod mollusk in the family Helicidae, the true snails or typical snails.
Helix nucula is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Helicidae, the typical snails. It has a rounded shell with white aperture margins; it differs from the similar Helix figulina by fine spiral grooves on the upper shell surface. Previously, the name H. nucula was used also for Helix pronuba, an unrelated species occurring in North Africa and on Crete, creating some confusion in the literature.
Allognathus campanyonii is a species of land snail in the family Helicidae, the true snails.
Allognathus hispanicus is a species of land snail in the family Helicidae, the true snails. This species is endemic to Mallorca, one of Spain's Balearic Islands. The common name is "caragol de Serp", due to the pattern of its shell.
Theba macandrewiana is a species of land snail of the family Helicidae, endemic to the Savage Islands of Portugal. Its shell is around 19.4 millimetres (0.76 in) in length.
