The CGS Salvelinus collections of decapod crustaceans from south Beaufort Sea to Cambridge Bay in 1960–65 comprised 1830 specimens of 15 species. Five of the species were not previously recorded from this area. Most abundant species were Sabinea septemcarinata and Eualus gaimardi. Eualus macilentus and E. stoneyi were confined to Bathurst Inlet. Westward setting currents along the Beaufort Sea coast mediate against incursions by Pacific species but Chionoecetes opilio, Hyas coarctatus alutaceus, and a species of Pagurus seemed to have overcome this condition. The species in which the highest percentages of females presumably reproduced annually were Spirontocaris phippsi, S. spinus, and S. septemcarinata.
