Two zoologists with considerable experience in the Canadian Arctic suggested to the writer that the “Gammarus Problem” would be an extremely interesting subject for investigation, and one which has several advantages, for material is relatively easy to obtain, and there are a number of species available. The precise studies on the species and sub-species of this amphipod genus in British estuaries are well known, and have been cited as examples in discussions on speciation and “new systematics”. In North America such studies are lacking and the time seemed opportune to try to elucidate the relationships between some of the forms living on these shores. In particular the species from northern waters were of interest. Dr. E.L. Bousfield (1958) has described the fresh-water amphipods of North America, and is currently preparing an account of the systematics of coastal species. This account provided material for the present discussion on the general relationships of North American species, but as it has not yet been published the reference “personal communication” or “pers. comm.” is used throughout the discussion.
