During a portion (28 June-24 August, 1967) of the global expedition of the U.S. National Oceanic and Atmospheric Administration ship Oceanography quantitative zooplankton samples were collected between Bombay, India and Freemantle, Australia. Five stations were taken between Bombay and the southern tip of Ceylon, five from Ceylon to the northern tip of Sumatra, three in the south eastern Java Sea, and twelve between Java and Freemantle. A total of 36 oblique tows was made in the upper 50 m with the ICITA one-meter plankton net and the Indian Ocean Standard net. Distribution and abundance of SO taxa of pelagic amphipods are presented. The percentage contribution, by numbers, of the amphipods to the total zooplankton averaged less than 1 %. This value is believed to be low due to avoidance by the amphipods ; also the volume of the individual amphipods was greater than other more numerically abundant zooplankton.
