Giffordius is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Polygyridae.
The two known species, found on Isla de Providencia (or Old Providence), were named after the early conservationist and politician, Gifford Pinchot and his wife, Cornelia, whose expedition discovered them. [2] These snails are unusual among polygyrids in being ovoviviparous rather than oviparous. [3]
The genus Giffordius contains the following species:
Henry Augustus Pilsbry was an American biologist, malacologist and carcinologist, among other areas of study. He was a dominant presence in many fields of invertebrate taxonomy for the better part of a century. For much of his career, his authority with respect to the classification of certain substantial groups of organisms was unchallenged: barnacles, chitons, North American terrestrial mollusks, and others.
Bulimulus is a genus of small to medium-sized tropical or sub-tropical, air-breathing land snails, pulmonate gastropod mollusks in the subfamily Bulimulinae within the family Bulimulidae.
Vertiginidae, common name the whorl snails, is a family of minute, air-breathing land snails, terrestrial pulmonate gastropod molluscs or micromollusks in the superfamily Pupilloidea.
Ptychotrema is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Streptaxidae.
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.
Achatinellidae is a family of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Pupilloidea.
Camaenidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea, the typical snails and their allies. This is one of the most diverse families in the clade Stylommatophora.
Subulininae is a subfamily of small tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Achatinidae.

Euglandina is a genus of predatory medium- to large-sized, air-breathing, land snails, terrestrial pulmonate gastropod mollusks in the family Spiraxidae.
Liguus is a genus of large tropical air-breathing land snails, more specifically arboreal or tree snails, terrestrial pulmonate gastropod mollusks in the family Orthalicidae.
Punctum is a genus of very small air-breathing land snails, terrestrial pulmonate gastropod mollusks or micromollusks in the family Punctidae, the dot snails.
Holospira is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Urocoptidae.
