By Mary J. Ratugun, Associate in Zoology, United States National Museum. The known range of several species is extended by the specimens obtained by the Canadian Arctic Expedition. Five of the species of Spirontocaris are shown to have a more complete circumpolar distribution, while Paralithodes camtschaticus is recorded for the first time from the Arctic (occurrence possibly accidental), and Pagurus brandti seems to reach as far north in Bering sea as Norton sound. Attention is called to the distributional charts of von Hofsten (see bibliography) in some of which notable gaps are filled or reduced by the new data here published. As nearly all of the species of shrimps collected by the Canadian Arctic Expedition were described and their synonymy worked out in the author’s report on the decapod crustaceans of the Harriman Alaska expedition (see bibliography), a reference to that work is made under each of those species in the list below. It may be noted that the care with which the specimens were obtained and preserved is due to Mr. Frits Johansen, naturalist of the expedition. LIST OF THE SPECIES. Order DECAPODA. Suborder NATANTIA.

Some of the Decapod-Crustacea collected by the ‘‘ Neptune ”’ Expedition, 1903-4, were sent in 1905 to Prof. G. O. Sars, Christiania, Norway, for iden- tification; and are published in the report of the Canadian Fisheries Museum, Ottawa, for 1905 (Department of Marine and Fisheries, Ottawa, Canada). As these specimens are still in Christiania, they have not been examined in the U. 8S. National Museum, Washington, nor included in the list above.
