Biology of the Antarctic Seas XXI

Published by the American Geophysical Union as part of the Antarctic Research Series, Volume 52. The eunicemorph polychaetes from Antarctic and Subantractic seas are reviewed, and new data adding to the knowledge of the eunicemorphs from New Zealand, Australia, Chile, and Argentina have been included. The systematics of the order Eunicemorpha is discussed, and suggestions are made pertinent to the status and definition of some families. It is proposed to merge the Lysaretidae with the Lumbrineridae, and the Oenonidae with the Arabellidae, and to redefine the Iphitimidae as a family independent of the Dorvilleidae.
