Cryptomastix is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Polygyridae.

These snails cannot be differentiated from related polygyrids solely on the basis of their shell characters. Instead, the details of the male anatomy must be examined.

Distribution[]

This genus of snails is restricted to the northwestern United States, and to adjacent areas of British Columbia, Canada.[1]
