Terrestrial
Gastropods of the Columbia Basin, British Columbia

| Format of this Report
In the species descriptions the format is as follows: species are arranged alphabetically within their respective genera and genera are arranged alphabetically within subfamilies or families. All higher categories are arranged in systematic or phylogenetic order, following the systematic checklist. No diagnoses of higher groups are given, and only important literature references, other than Pilsbry (1939-1948), are given for supraspecific taxa. For each species, the Latin name with author and date is given. Synonyms likely to be encountered in other publications and particularly those made since Pilsbry (1939-1948) are given. Special emphasis is placed on synonymous names used in connection to British Columbia or immediately adjacent areas. Species accounts emphasize the shells of snails and the bodies of slugs. The colour and outward appearance of the body of snails is also noted when known. Following the description, either a full comparison with similar species or a referral to another species is given. In the latter case, the full comparison will be made under the referred species. The habitat of each species is noted with special emphasis on habitats of British Columbia populations. The species' world-wide range, or distribution, is given, and its occurrence in British Columbia. Notes on taxonomy, problematic records, etc., and finally derivations of the currently valid scientific name are presented. For genera with multiple species, the derivation of the generic name is given under the first species only. Records based on museum or private collections, list locality, geoposition and a catalogue number. For literature records, locality, geoposition and reference(s) are noted. Unless given in the original reference or collection data, latitudes and longitudes of records were secondarily obtained from a gazetteer or other sources. Records are ordered south to north and east to west. The distribution maps show only the Columbia Basin records. A filled circle ( · ) indicates that the record is based on museum or private collections. An open circle ( ° ) indicates a literature record. A circle may represent more than one record when localities are too close to plot separately, and when a collection record coincides with a literature record, the collection record takes precedence. |
