E V I O R A Mmseiuim of Comparative Zoology Cambridge, Mass. October 11, 1956 Number 63 NEW BATHYAL ISOPODA FROM THE CARIBBEAN WITH OBSERVATIONS ON THEIR NUTRITION By Robert J. Menzies Marine Zoologist Lamont Geological Observatory! (Columbia University) Palisades, New York INTRODUCTION AND ACKNOWLEDGMENTS In this paper 5 new species including 1 new genus of marine Isopoda are described. All were collected by the R/V VEMA, Cruise 8, 1955-56 with a single trawl using the closing-opening Epibenthic Trawl (Menzies, in press) from bathyal depths (680 fms.) in the Caribbean Sea at 16° 59.1' N. Latitude and 79° 07.9' W. Longitude (South of Jamaica). The substratum con-sisted of pteropod and foraminiferal ooze. In addition to isopods, the trawl contained polychaete worms, a few ophiuroids and several amphipods. The specimens have been deposited in the Museum of Compara-tive Zoology (abbreviated MCZ) whose publication of this manu-scrijit is appreciated. The research was supported by a Rockefeller Foundation Grant RF 54087 for research in deep sea biology. ECOLOGY AND NUTRITION The "stomach" contents of Acanthocope spinosissima Menzies (this paper, p. 2) which packed the gastric mill to swelling con-sisted foremost of bacteria-size and shape particles and some globular bodies, possibly protozoans. Next in abundance were 1 Lamont Geological Observatory, Contribution No. 219, Biology Program No. 7.
