"CFIA P1045E-22." Includes bibliographical references and indexes. "In a country where native earthworms are mostly inconspicuous and make up 27% of the species, the vast majority are introduced aliens from Europe (67%) or the Orient (6%). Most of the introduced European species are now ubiquitous over large areas of Canada, although six species are considered rare, and have scarcely spread from where they were introduced. Except for two species, the native earthworms are restricted to British Columbia and the Yukon. Based on fieldwork covering more than 50 years, and the author's knowledge of the fauna, this book describes and illustrates the 33 species reported in Canada. For each species, genus and family, - synonymy, type species, diagnosis, biology, reproduction, climatic zone, ecological type, origin, range, and North American distribution are described. The book also includes an extensive literature section, illustrated glossary and a key to the 33 species." Earthworms Canada. Lumbricidae Canada. Megascolecidae Canada.
