BATIIYFELAGIC CALANOID COPEPODS 

 OF THE WESTERN INDIAN OCEANS 



By George D. Grice and Kuni Hulsemann^ 



The plankton and midwater trawl samples on which this paper is 

 based were obtained during two cruises of R. V. Anton Bruun in 1963 

 and 1964, which, at that time, was participating in the Biological 

 Program of the International Indian Ocean Expedition. The area 

 in which the samples were collected extends from the northern Ara- 

 bian Sea to approximately the latitude of the subtropical convergence 

 in the southern Indian Ocean. The operation of the Anton Bruun 

 in the Indian Ocean provided us with an opportunity to extend our 

 studies on the systematics and the zoogeography of the bathypelagic 

 calanoid copepods from the Atlantic to the Indian Ocean. 



We would like to thank Misses Ann Mulcahy and Mary Ann 

 Beecher for their |help in sorting and counting the copepods of the 

 plankton samples and Miss Cecilia Simons for inking the original 

 figures. Mr. Bruce Rogers assisted in collecting the samples at sea.
