Stenotrema is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks 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".
Distribution
The genus occurs throughout most of North America, from Alaska, though Canada and the United States, into Mexico.[2]
