characters of the swimming legs. Since these legs are 

 missing from most specimens, characters of the swim- 

 ming legs have been correlated with other, relatively 

 stable, characters, especially the armature of Mxp 

 and body form and size. Characters used in the keys 

 to genera and species have been selected so that 

 usually even damaged specimens without swimming 

 legs can be identified. 



Males of most Spinocalanus species are left- 

 handed, but males of S. polaris and S. similis are 

 right-handed; the handedness is reflected not only in 

 P5 but also in Al. Known males in other genera of 

 Spinocalanidae are left-handed. 



Within the Spinocalanidae, Spinocalanus and 

 Monacilla appear to form one subgroup, while 

 Mimocalanus and Teneriforma comprise a second 

 subgroup. However, most appendages of Monacilla 

 and Teneriforma species are still undescribed. 



Males are not yet known for most of a complex of 

 species related to Spinocalanus spinosus: S. 

 aspinosus, S. hoplites, S. oligospinosus, S. spinosus, 

 and S. usitatus. Undoubtedly, knowledge of these 

 males will help clarify the relationships of the 

 females, which are very similar to one another. 



Males are also unknown for S. abruptus and S. hir- 

 tus; Monacilla tenera and M. gracilis; Mimocalanus 

 cultrifer, M. inflatus, M. major, and M. ovalis. The 

 female of Monacilla sp. is unknown. 



Males of S. terranovae, Monacilla sp., and 

 Mimocalanus heronae are each known only from one 

 briefly described specimen. More specimens of S. 

 abruptus, S. hirtus, Monacilla gracilis, Mimocalanus 

 inflatus, M. major, and M. ovalis should be examined 

 to confirm or clarify the status of these species. 



ACKNOWLEDGMENTS 



T. Saunders English, Department of Oceanography, 

 University of Washington, provided the opportunity, 

 through the Office of Naval Research (Contract 

 N00014-67-A-0103-0005 Project NR083 012), for me to 

 participate in his initial field work on Fletcher's Ice 

 Island in 1966, and he also arranged for me to receive 

 the plankton samples from 1967-68. 



In connection with her own research with T. 

 Saunders English, Gayle A. Heron often noticed rare 

 specimens of Spinocalanidae and without exception 

 furnished them for this study. She also helped to for- 

 mulate the problems in the systematics of this group, 

 and remained a valuable source of ideas throughout 

 the investigation. 



Thomas E. Bowman, Smithsonian Institution, 

 provided much necessary and valuable assistance 

 during the research. I wish to thank him and Fenner 

 A. Chace, Jr., for critical reviews of the manuscript. 



I owe a principal and collective debt to the several 

 persons and institutions who graciously and generous- 

 ly furnished valuable specimens for study: G. M. 



Bennell, British Museum of Natural History (BM); 

 Janet M. Bradford, New Zealand Oceanographic 

 Institute (NZOI); Marit E. Christiansen, Zoological 

 Museum, University of Oslo (OSLO); A. Fleminger, 

 Scripps Institution of Oceanography (SIO); H. A. 

 Fehlmann, Smithsonian Oceanographic Sorting 

 Center (SOSC); Julio Vidal, formerly with the Arctic 

 Program, Office of Naval Research, University of 

 Southern California (USC); the United States 

 National Museum (USNM); the University of 

 Washington (UW); George D. Grice, Woods Hole 

 Oceanographic Institution (WHOI); and Tai Soo 

 Park, Texas A&M University Marine Laboratory. 



I also wish to acknowledge the assistance of K. 

 Moore in the final preparation of the figures. 



This report was adapted from a dissertation sub- 

 mitted to The George Washington University in par- 

 tial satisfaction of the requirements for the degree of 

 Doctor of Philosophy.
