MARINE AMPHIPODA 

 OF ATOLLS IN MICRONESIA 



By J. Laurens Barnard 



Associate Curator, Division of Crustacea 



Introduction 



Two large collections of intertidal and sublittoral Amphipoda were 

 made on several atolls of Micronesia, one containing material coUected 

 by Dr. D. P. Abbott of Stanford University and Dr. F. M. Bayer of 

 the Smithsonian Institution on Ifaluk Atoll, and by Dr. Cadet Hand of 

 the University of California on Kapingamarangi Atoll, and the other 

 by Dr. D. J. Reish of Long Beach State CoUege, California, on 

 Eniwetok, Majm-o, and Bikini atolls. The Abbott-Bayer-Hand 

 collection was made avaUable to me by Dr. Fenner A. Chace, Jr. of the 

 U.S. National Museum, and a small grant was provided' from the 

 National Research Council for initial sorting of the specimens. The 

 coUections of Dr. Reish were made possible by help from the Atomic 

 Energy Commission. All specimens have been deposited m the U.S. 

 National Museum. I am most grateful to the Beaudette Foundation 

 for my support during this investigation. Dr. Abbott very kmdly 

 reviewed the manuscript and made several valuable suggestions. 



Previous studies.— Tropical Pacific amphipods have not been 

 studied extensively but the fauna would be expected to contam species 

 common to other parts of the tropics, such as the Indian Ocean and 

 Red Sea. Therefore, few of the common species in the coUections 

 proved to be new, especially since Schellenberg (1938a) had already 

 reported on coUections from Fiji, GUbert, EUice, MarshaU and
