Sagdoidea is a superfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the infraorder Helicoidei of the suborder Helicina. [1]
Stylommatophora is an order of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs. This taxon includes most land snails and slugs. Stylommatophorans lack an operculum, but some close their shell apertures with temporary "operculum" (epiphragm) made of calcified mucus. They have two pairs of retractile tentacles, the upper pair of which bears eyes on the tentacle tips. All stylommatophorans are hermaphrodites.
Neritoidea is a taxonomic superfamily of mostly sea snails, nerites and their allies, marine gastropod mollusks in the order Cycloneritida.
Bulimulidae is a taxonomic family of medium-sized to large, air-breathing, tropical and sub-tropical land snails, terrestrial pulmonate gastropod molluscs in the superfamily Orthalicoidea.
Bradybaeninae is a taxonomic subfamily of medium-sized to small land snails, terrestrial pulmonate gastropod mollusks in the family Camaenidae, superfamily Helicoidea.
Helicoidea is a taxonomic superfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora.
Sagdidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks with highest diversity in the Greater Antilles. It has been classified in its own superfamily Sagdoidea and as a member of the superfamily Helicoidea. Some species of Sagdidae are ovoviviparous.
Polygyridae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.
Xanthonychidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.
Monadeniinae is a taxonomic subfamily of small to medium-sized air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Xanthonychidae
Sigmurethra is a taxonomic category of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs. This is an informal group which includes most land snails and slugs.
Lucerna bainbridgii is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Pleurodontidae.
The Rhytidoidea are a superfamily of air-breathing land snails and slugs, terrestrial gastropod mollusks in the suborder Helicina.
Oxynooidea is a superfamily of small sea snails, bubble snails and bivalved gastropods, marine gastropod mollusks within the superorder Sacoglossa.
Zachrysia is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Zachrysiidae
After excluding groups not related, the informal group Sigmurethra has become the suborder Helicina, with the following infraorders and a collection of families with no superfamily:
Gonostomopsis is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the subfamily Pleurodontinae of the family Pleurodontidae.
Isomeria is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Labyrinthidae.
Zachrysiidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Sagdoidea.
Lucerna is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the subfamily Lucerninae of the family Pleurodontidae.
The Pupilloideiis an taxonomic infraorder of air-breathing land snails, semislugs and slugs, terrestrial pulmonate gastropod molluscs in the suborder Helicina.
