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.
Cryptomastix is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Polygyra is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Stenotrema is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae. These are typically small to medium-sized snails, with a velvety or hairy shell surface, and a narrow aperture which is usually closely guarded by well-developed "teeth".
Vespericola is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
Polygyridae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea.
