Janulus is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Gastrodontidae.
Species within the genus Janulus include: [2]
Vertigo is a genus of minute, air-breathing land snails, terrestrial pulmonate gastropod molluscs or micromollusks in the family Vertiginidae, the whorl snails.
Columella is a genus of very small, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Truncatellinidae, the whorl snails and allies.
Caseolus is a genus of land snails in the family Geomitridae.
Disculella is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Geomitridae, the hairy snails and their allies.
Hemicycla is a genus of medium-sized air-breathing land snails, terrestrial pulmonate gastropods in the family Helicidae, the typical snails.
Lemniscia is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Geomitridae, the hairy snails and their allies.
Spirorbula is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the subfamily Geomitrinae of the family Geomitridae, the hairy snails and their allies.
Truncatella is a genus of very small land snails with an operculum, terrestrial gastropod mollusks in the family Truncatellidae. These small and minute snails live on land, very close to seawater. They walk with a strange looping action, and the adults have truncated shells. Many of the species are small enough to be considered micromollusks.
Aegopinella is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Gastrodontidae, the glass snails.
Montfortula is a genus of keyhole limpets, marine gastropod molluscs in the subfamily Emarginulinae of the family Fissurellidae.
Hemitoma is a genus of slit limpets, marine gastropod molluscs in the family Fissurellidae, the keyhole limpets and slit limpets.

Labyrinthus is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Labyrinthidae.
Mangelia is a large genus of sea snails, marine gastropod mollusks in the family Mangeliidae.
Apula is an extinct genus of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the subfamily Klikiinae † of the family Elonidae.
Leptoconchus is a genus of medium-sized sea snails, marine gastropod mollusks in the family Muricidae, subfamily Coralliophilinae, the coral snails or coral shells.
Sanguinolaria is a genus of saltwater clams, marine bivalve molluscs of the family Psammobiidae.
