This report is based upon collections made by the author at Eniwetok, Bikini, and Majuro atolls during the summers of 1956 and 1957. In addition, previous accounts of the polychaetes from the Marshall Islands, largely those reported by Hartman (1954
a), are incorporated in this study. The object of the field investigations was to prepare a reference collection of polychaetes for the Eniwetok Marine Biological Laboratory. Keys to the species within the families and references have been added as an aid to identification. The material upon which this study was based, including all holotypes and paratypes, has been deposited in the polychaete collections of the United States National Museum. A duplicate collection has been placed in the museum of the Eniwetok Marine Biological Laboratory. The author is indebted to Dr. Robert W. Hiatt for his assistance during the course of the field investigations.
