During the 1978–1979 season of the Ross Ice Shelf Project, calanoid and harpacticoid copepods were captured at the J9 site (82°22.5′S, 168°37.5′W). It is deduced that these copepods are scavengers as they were attracted to bait. At least five species were taken, three of them previously undescribed: Xanthocalanus harpagatus n.sp., Xanthocalanus sp. copepodites, Tharbyis magna n.sp., Tisbe spinulosa n. sp., T. prolata Waghorn, and Longipedia weberi A. Scott. Tisbe prolata is herein partially redescribed. Tharybis magna and Tisbe spinulosa, at least, appear to be able to complete their life cycles under the ice; both sexes and some copepodites were taken and neither species has been taken in the open sea. The significance of their discovery, in this environment isolated by some 450 km from the open water of the Ross Sea, is discussed.
