this work is intended as a guide for the identification of land snails and slugs of the Pacific northwest, for use by biologists and other interested individuals who wish to identify most species in the field or laboratory without the necessity of dissecting the animals or sending them to a genetics laboratory. while not all species can be positively identified without the aid of dissection or molecular analysis, with this guide and some practice, most specimens should be recognizable to species. if a more exact identification is required, the specimens can be forwarded to a malacologist or genetics laboratory for further study. however, interested biologists and students of nature will find a large degree of satisfaction in observing and identifying these animals for themselves, and there is a definite need for such guides to identification of the lesser-known animals.
