I02 DISCOVERY REPORTS 



District. Champsocepholus giimiari is found also at South Georgia, and a related species, 

 C. esox, in the Patagonian Region. Chaenichthys (with two species) is a genus peculiar 

 to the island of Kerguelen, but belongs to a family, most of the members of which occur 

 in the Glacial District. 



Thus, the only way to show the dissimilarity of the fish-fauna of the Kerguelen- 

 Macquarie District from those of the Patagonian Region and the Antipodes, and to 

 express its affinity to that of Antarctica, is to include it in the Antarctic Zone as a 

 separate district (Regan, 1914^, p. 36). 



I do not propose to discuss the question of the origin of the Antarctic fish-fauna in 

 this report, and have nothing to add to the general conclusions of Regan {t.c, p. 40). 

 As he points out, "the distinctive features of the fish-fauna. . .are that nearly all the 

 genera and species are peculiar and that they nearly all belong to a single group, the 

 Nototheniiformes, which is characteristic of and almost restricted to the Antarctic 

 and Subantarctic Zones. In the Antarctic Zone this group has developed into a large 

 number of types that diiTer greatly in structure, appearance and habits. These facts 

 seem to point to the conclusions that Antarctica may have long been isolated and that 

 its coasts may have been washed by a cold sea for a long time, probably throughout 

 the Tertiary Period." Regan has also shown that neither the fresh-water fishes, nor 

 the marine fishes, whether Antarctic or South Temperate, support the theory that the 

 Antarctic Continent connected South America with Australia during the Tertiary 

 Period.
