Pelagic shrimps belonging to the family Oplophoridae collected on USNS Eltanin cruises 10, 11, 14–16, 19–21, 24, and 25 are the subject of this study. The cruises, made between October 1963 and November 1966 as part of the U.S. Antarctic Research Program, covered a wide area of the Pacific sector of the Southern Ocean, from 74°14′W to 162°06′W and from the region of the Subtropical Convergence at 33°00′S to 69°00′S, well south of the Antarctic Convergence (Antarctic polar front). The major hydrographic features of the Pacific sector of the Southern Ocean and the biogeography of the Southern Ocean are reviewed. A total of 2415 oplophorid specimens representing 10 species from five genera were identified from the materials. Oplophorus novaezeelandiae, Acanthephyra stylorostratis, A. quadrispinosa, A. pelagica, Hymenodora glacialis, H. gracilis, Systellaspis braueri, and Notostomus elegans?, as well as two new species, Notostomus sparsidenticulatus and Systellaspis eltanini (11 specimens of the latter species were obtained from the German FRS Walther Herwig. cruise 36 in the South Atlantic). Keys are presented for the identification of the oplophorid genera and species from the samples. Species discussions include illustrations, synonymies, diagnoses, brief lists of materials, summaries of geographic and depth distributions, and general remarks. Maps of the geographic distribution in relation to the Antarctic and Subtropical convergences in the study area are presented for each species, and the patterns of distribution of the species are discussed in relation to the major hydrographic regions of the Pacific sector of the Southern Ocean.
