The present study is based on examination of six collections of fishes (about 4000 specimens) from the Hudson bay region made between 1919 and 1930. The material consisted of 45 different forms, belonging to 42 species, 34 genera and 17 families.No endemic species are known from this area. The following subspecies are described as new: Ammodytes dubius hudsonius, Gymnocanthus tricuspis hudsonius and Lycodes reticulatus hacheyi.Sixteen fresh-water and brackish-water forms collected in the Hudson bay area are the same as those that occur in the Great Lakes and St. Lawrence regions.Twenty-eight marine species are known from the region under consideration; the majority of them (22) are truly arctic forms.Two species (Gymnocanthus galeatus and Liparis cyclostigma) previously known only from the north Pacific and Bering sea are found in Hudson bay.The most important commercial fishes are principally anadromous and rarely marine.
