Euchemotrema is a genus of small, air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
The shell of species in this genus is usually about 8 to 11 mm in diameter (about 3/8 inch). The shells are brown with a velvety surface, similar to that of Stenotrema , and, in fact, this genus is sometimes combined into Stenotrema. [2] These snails typically have a less complex aperture than Stenotrema: "without a tooth within the outer arc of the lip and with no notch in the basal lip". [2]
There are also peculiarities of the male anatomy that separate the two genera.
Euchemotrema is widely distributed in eastern and central North America.
This genus includes the following species and subspecies: [2] [3] [4]
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.
Pagodulina pagodula is a species of minute land snail, a terrestrial pulmonate gastropod mollusk, or micromollusk, in the family Pagodulinidae, and the superfamily Pupilloidea.
Cryptomastix 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".
Rich Mountain slitmouth or Pilsbry's narrow-apertured land snail, scientific name Stenotrema pilsbryi, is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Polygyridae. This species is endemic to Ouachita Mountains of the United States.
Vertigo arthuri is a species of land snail in the family Vertiginidae, the whorl snails. It is known by the common names callused Vertigo, or Midwest Pleistocene Vertigo.
Vespericola is a genus of air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Polygyridae.
