The decapod fauna of Ungava Bay (17 species in 3000 specimens collected) is shown to be similar to that of the shallow water areas of west Greenland. Four species are reported for the first time from Ungava Bay: Sergestes arcticus and Pasiphaea tarda, ordinarily from deeper and warmer water, and Eualus macilentus and Sabinea septemcarinata. Species found in or originating in the Pacific were taken in greater numbers. Systematics of each species is treated under occurrence in Ungava Bay, world distribution, and taxonomy. Lengths of most species of shrimp showed that a greater size was reached in females. Maturities with respect to size when first mature, egg size, and times of hatching and spawning are discussed. Males were found to be mature at a size smaller than first-mature females. The high percentage of stations at which decapods, including larvae, were taken, and their occurrence in the stomachs of many seals and fish attest their prevalence and their importance in the area.
