A preliminary survey of known and potentially Canadian millipedes (Diplopoda)

This paper complements a similar one in this issue for the Centipedes (Chilopoda) and Symphyla. The diplopod fauna of Canada, as currently known, is briefly discussed and the relevant literature is summarized. The main body of the paper comprises a classified checklist of species, with their recorded distribution, known to occur in Canada and the adjacent United States of America, together with a few others from a little farther south that might conceivably be anticipated. Over 60 species are listed for Canada and Alaska, together with about the same number of additional species hitherto known only as far north as those states immediately south of the international boundary. The European Archiboreoiulus pallidus (Brade-Birks) is recorded for the first time from North America.
