COPEPODA. 



typically Antarctic species ever find their way northwards Ity way of the deep Atlantic 

 trough, but there is little evidence of it in the many collections made by the ' Gauss ' 

 throughout its Atlantic traverse. A certain number of species which are ubiquitouB, 

 such as Oiikona xiiuili*, some species of Oncea, l/nlnjifi/n^ longicomis, (Jiii<lin* 

 fi'iiuixjti/iu* and in/ijnr, and Gni'tainix (unii/i/i'i; and possibly r,n/</<n/i), extend from the 

 Faroe Channel to the southern ocean ; but so far as the evidence at present goes, 

 the Antarctic Copepod fauna is distinct from that of the Arctic seas, and the species 

 which are typical of this region, and most numerous, do not extend far into the 

 Southern Atlantic. As no observations have been made of the Copepod fauna of the 

 deep water of the Indian Ocean, it is quite possible that Antarctic species may bear a 

 considerable extension northwards in this direction. 



It is curious that no great number of Harpacticidse appear in the collections of the 

 'Discovery,' only three examples all told of Harpacticu* fur<'ifi'i-, which is somewhat 

 different from any Harpacticus of the northern hemisphere ; and only five are described 

 from the 'Belgica' collection by Dr. Giesbrecht, two of which (//. brevicornis, H. dxiifcr), 

 are identical with northern species. A fair number of species occur in the ' Gauss ' 

 collection, but these have not yet been examined. 



The paucity in numbers of the Harpacticidse in the ' Discovery ' captures is no 

 doubt due to the mode of collection.

The species first described by Brady as Calm/a* propinguus has been subsequently 

 described by Giesbrecht, who now concludes ('Belgica' report, p. 1G) that the copepod 

 described by himself in 18U2 as C. propinquus from the 8.W. Atlantic, between 37 and 

 52 S., is not this species, but one closely resembling it, t which he gives the name
