Cryptomastix germana, or the pygmy Oregonian, is a terrestrial snail belonging to the family Polygyridae.[1]

Distribution

This species is endemic to the top half of the Pacific Northwest, with its range cutting off at the top of California.[2][3][4][5][6]

Appearance

This species is characterized by a hairy shell in a classical spiral shape. It also is very small, usually only a few millimeters (Usually about 2mm).The hairs are generally long, hooked and spiraling. It generally has a "Leopard print" pattern on the shell[2][4][6]

Similar species

The most similar species to this snail would be Vespericola columbianus, which also has a hairy shell, but is much bigger than the Pygmy Oregonian, and has shorter hairs.[7]

Color forms

Some Cryptomastix germana individuals off the coast can be darker brown, reddish, to nearly black in coloration.[8][9]

The normal inland coloration is light brown with a leopard print pattern.[10][11]
