Terrestrial Gastropods of the Columbia Basin, British Columbia

Systematic Checklist of the Terrestrial Gastropods of the Columbia Basin, British Columbia This list includes all species of terrestrial molluscs known from the Columbia Basin of British Columbia, but two cautionary notes are necessary. Firstly, the classification is not final and is still undergoing change. This report does not attempt any taxonomic innovations toward a better system, and the classification used here was adopted from several sources, which means that the systematics of this checklist are not uniformly grounded in modern techniques, since most groups have not been revised in many years. Secondly, this checklist is probably not complete, given that the Columbia Basin region (and much of British Columbia) has not been thoroughly explored for terrestrial molluscs. Several introduced species are included in this list and are indicated by an asterisk. Following the main list is a second list of species that have been recorded from areas adjacent to the Kootenays, but which have not yet been collected there.
