None. Begins: "The five new species and four new genera of polychaete worms described herein were obtained from four sources: 1. Two species, a hesionid and a dorvilleid, collected by Pierre Brunei and others in the Gulf of St. Lawrence and found in the collections of polychaetes at the Station de Biologie Marine, Grande-Riviere, Gaspe, Province of Quebec, Canada, where I worked during the summer of 1959. 2. One species of polynoid, collected by Roland L. Wigley and others off Massachusetts and found in the collections of polychaetes at the U.S. Fish and Wildlife Station at Woods Hole, Massachusetts, where I worked during the summer of 1960. 3. One species of polynoid from the Gulf of Mexico, a part of a collection from Seahorse Key, Florida, sent to me by John L. Taylor. 4. One species of hesionid (some 200 specimens) from the Middle Congo, West Africa, found in the mantle cavities of Tellina and sent to me by Arthur G. Humes. In working up the new genus and species of dorvilleid, it seemed advisable to revise the genera of Dorvilleidae by erecting another new genus and re-establishing a third."
