Thirty-six species of land gastropods are reported from 14 localities. Eighteen species are first records for the island, and 10 of those are new county records. Two exotic species, Polygyra septemvolva and Bradybaena similaris, do not appear to be established, and are unlikely to survive the Michigan winter outside of a greenhouse.
