DISCOVERY REPORTS 



9 species are known from both sides of the Antarctic, of the Bathydraconidae, 3 out of 

 12 species, and of the Chaenichthyidae, 2 out of 8 species. 



As Regan has pointed out {t.c, p. 36), the affinities of the Nototheniiform fishes 

 found at South Georgia are predominantly Glacial, and the presence of Notothenia 

 larseni near Bouvet Island suggests that this island is also rightly included within this 



area. 



Kergiielen-Macquarie District 

 This district includes Marion and Prince Edward Islands, the Crozets, Kerguelen, 

 Heard Island, and Macquarie Island. I have dealt with the fish-fauna in some detail 

 in my report on the fishes obtained by the B.A.N. Z. Antarctic Research Expedition, 

 but it may be of interest to summarize the conclusions here. The following table shows 

 the distribution of the species of coastal fishes so far recorded from this district : 



Table II. 



It is clear that, although the coastal fish-fauna of this district shows certain features 

 of resemblance to that of the Patagonian Region and the Antipodes, its affinities are 

 mainly with that of Antarctica. 



Of the Nototheniiform fishes, the characteristic Antarctic genus, Trematomus, is 

 absent from the Kerguelen-Macquarie District, but in the genus Notothenia the 

 " tessellata'' group so characteristic of the Patagonian Region is also wanting. Five 

 species of Notothenia are peculiar to the district, all of which appear to be most nearly 

 related to species occurring in the Glacial District, and mostly to species characteristic 

 of the Weddell Quadrant. Of the remaining species, A^. coriiceps and N. rossii are found 

 elsewhere only in the Glacial District. N. macrocephala, however, occurs in both the 

 Patagonian Region and the Antipodes, but not in the Antarctic, and N. colbecki in the 

 Antipodes. Harpagifer bispinis occurs in the Patagonian Region as well as in the Glacial
