NO. 8583 COPEPODS — GRICE AND HULSEMANN 13 



in the present paper, is further indication of the paucity of prior 

 taxonomic studies on the deep-water copepods of the Indian Ocean. 



Taxonomy 



One new genus, 17 new species, 8 previously unknown males, and 

 1 previously unknown female of calanoid copepods are described 

 below. Systematic or distributional remarks are presented for 25 

 other species. Also included are descriptions and figures of 9 speci- 

 mens which, because they may be referable to described species, are 

 not recognized as new. Seven additional species of Lucicutia from 

 these collections, which were not previously known from the Indian 

 Ocean, are reported by Hulsemann (19G6). In all, 310 species 

 (300 were specifically identified) were found in the collections. 



The forms of Clausocalanus arcuicornis (Dana) and Microcalanus 

 pygmaeus (Sars) were not distinguished. The species designated 

 Euchaeta species is being described elsewhere by Dr. Marion Fon- 

 taine. 



In the description of the species the first to fifth thoracic segments 

 refer to those to which the first to fifth pairs of feet are attached. 



Holotype specimens have been deposited in the U.S. National 

 Museum, Washington, D.C., and representative specimens of other 

 species have been deposited in the Woods Hole Oceanographic 

 Institution collections. 



Species and collection numbers where they occurred are listed below. 

 (The 78 species not previously laiown from the Indian Ocean are 

 indicated by an asterisk. See table 1 for collecting data corresponding 

 to collection number.)
