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.
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.
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.
Clausiliidae, also known by the common name door snails, is a taxonomic family of small, very elongate, mostly left-handed, air-breathing land snails, sinistral terrestrial pulmonate gastropod mollusks.
Ptychotrema is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the subfamily Enneinae of 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.
Streptaxidae is a family of carnivorous air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora. Six Streptaxidae subfamilies are accepted in the 2005 taxonomy of the Gastropoda by Bouchet & Rocroi.
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.
Polygyridae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.
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.
Urocoptidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Urocoptoidea.
Holospira is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Urocoptidae.
Rectaxis is a genus of predatory air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Spiraxidae.
Potamolithus is a genus of small freshwater snails that have an operculum, aquatic gastropod mollusks in the family Tateidae.
The Pinchot South Sea Expedition was a 1929 zoological expedition to the Caribbean and South Pacific led and financed by Gifford Pinchot.
