Terrestrial mollusks, the second largest phylum in the animal kingdom, are vitally important to the earth's ecology. With the publication of Land Snails and Slugs of the Pacific Northwest, a definitive and comprehensive guide to snails and slugs of Oregon, Washington, Idaho, and western Montana is finally available. Primarily an identification guide, this richly illustrated volume offers complete information on the range of terrestrial mollusk shapes, sizes, and characteristics. It presents an overview of their habitat requirements as well as details of land snail and slug ecology, collection and preservation methods, and biogeography. Land Snails and Slugs of the Pacific Northwest is an essential reference for biologists, horticulturalists, gardeners, and naturalists, and anyone wishing to identify species in the field. * Identification keys and species accounts for most of the 245 taxa of terrestrial slugs and snails in the region * 280 full-color photographs of 155 species and subspecies * Range maps for most species

The islands of the Samoan archipelago lie about 14 degrees south of the equator in the central Pacific Ocean. Politically, they are divided into two groups: Samoa (formerly Western Samoa), an indepedent state and American Samoa, a territory of the USA. The islands have been formed as a result of complex volcanic activity; they are geologically young. While many of the plants and birds of the Samoan Islands are found elsewhere in the Pacific, many of the snail species are found nowhere else on Earth. This guide is intended to permit identification of mos of the terrestrial snails, and slugs of the Samoan Islands. It is intended to be accessible to the amateur naturalist but also to provide the experienced scientist with a compact resource of information. The guide covers both the native species and the non-native, introduced species, which are generall more frequently encountered, especially at low elevations and in habits disturbed by human activities.
