148 DISCOVERY REPORTS 



Regan 1 has made the following remarks with regard to the Kerguelen District. 

 "At the first glance it may seem that as so many characteristic Antarctic genera appear 

 to be absent and most of the Nototheniidae belong to Notothenia, which is well repre- 

 sented in the sub-Antarctic Zone, the Kerguelen District might be included in the latter. 

 But a more critical examination shows that the tessellata group, characteristic of 

 Magellan, is absent, that the squamifrons, acuta and marionensis groups are present and 

 are found elsewhere only in the Glacial District, and that the coriiceps group is repre- 

 sented by N. coriiceps, an Antarctic species, and by the related N. cyaneobrancha. The 

 only way to mark the dissimilarity of the fish-fauna of Kerguelen from that of Magellan 

 or of the sub-Antarctic islands of New Zealand and to express its affinity to that of 

 Antarctica is to include it in the Antarctic Zone as a separate district, small and 

 impoverished, but with well-marked characters." 



A closer study of the fish-fauna of the Patagonian region has shown that the dis- 

 similarity between this and that of Kerguelen is not so marked, and that the latter has 

 several features in common with the Patagonian region as well as with Antarctica. Two 

 species of Raja occur at Kerguelen: one (R. mnrrayi) is related to the Patagonian 

 R. macloviana, and the other (R. eatonii) is related to the Patagonian R. scaphiops. 

 Muraenolepis marmoratus is related to M. microps and M. orangietisis, both of which 

 occur in the Magellan District. The ' William Scoresby ' obtained a single specimen of 

 a new species of Notothenia from deep water near the Burdwood Bank, which is very 

 closely related to N. squamifrons from Kerguelen. Notothenia macrocephala has now 

 been recorded from Kerguelen,' 2 and this species occurs also in the Patagonian region 

 and in the Antipodes District but not in the Glacial District. Harpagifer bispinis is 

 also common to Kerguelen and the Patagonian region, but occurs in the Antarctic Zone.
