The first major work exclusively on the land snails and slugs of North America. Written by the American malacologist George Washington Tryon (1838-1888) and with fine illustrations by E. J. Nolan. Some species from brackish environments (Ellobiidae, Truncatelldae) are included. Provenance: small stamp of the American malacologist Richard Irwin Johnson (1925-2020) in the top margin of the front free endpaper recto and title. This is a rare work.
