290 FISHES. 



the Fauna of Magelhffin's Straits and Kerguelen's Land is 

 extremely similar to that of Iceland and Greenland. 



As in the arctic Fauna, Chondropterygians are scarce, 

 and represented by Acanthias vulgaris and species of Raja. 

 Holocepliali have not yet been found so far south, but Callor- 

 liynclius, which is not uncommon near the northern boundary 

 of this fauna, will prove to extend into it. 



As to Acanthopterygians, Gatafliradi and Scorpa;nidm 

 are represented as in the arctic Fauna, two of the genera 

 (Sehastes and Agonus) being identical. The Cottidce are re- 

 placed by six genera of Trachinidce, remarkably similar in 

 form to arctic types ; but Discoboli and the characteristic 

 Arctic Blennioids are absent. 



Gadoid Fishes reappear, but are less developed ; as usual 

 they are accompanied by Myxine. The reappearance of so 

 specialised a genus as Lycodes is most remarkable. Flat- 

 fishes are scarce as in the North, and belong to peculiar 

 genera. 



Physostomes are probably not entirely absent, but hitherto 

 none have been met with so far south. Lophobranchs are 

 scarce, as in the Arctic zone ; however, it is noteworthy that 

 a pecidiar genus, with persistent embryonic characters {Proto- 

 campus), is rather common on the shores of the Falkland 

 Islands. 



The following are the genera known from this zone. 

 Those with a single asterisk (*) are known to extend into 

 the Temperate zone, but not beyond it ; those with a double 

 asterisk (**) are limited to the Antarctic shores : — 



Kerguelen.
