out restricting the discussion in these cases to forms quoted in 
support of the bipolar hypothesis. 
The following is a list of all the Fishes known from the Ker- 
guelen area : — 
Trachinid^;. 
Notothoenia . — Seven species known from Kerguelen Island, 
and one other from Marion Island. One of the Kerguelen 
species is known also from the Aucklands, and about five 
from the Falklands, one of which ranges also to New 
Zealand. 
Harpagifer. — A single species only, known from the Falk- 
lands, Cape Horn, Marion and Kerguelen Islands. 
Chcenichthys. — A single species only, from Kerguelen. 
Dr Gunther speaks of these forms as representing the Cottoids 
of the north ; but it is clear that this suggestion is meant to be 
interpreted in the most general way, merely as we sometimes say, 
for instance, that the Humming-birds of the New World are re- 
presented, we might somewhat better say replaced, by the Sun- 
birds of the Old; the deer of northern regions by the antelopes 
predominant in Africa ; the dog, the beaver, the bear, and the 
mole of Europe by the Australian Thylacine, Wombat, Koala, and 
Notoryctes. Dr Gunther says, immediately afterwards ( Chat l . Rep., 
Shore Fishes, p. 14), that such resemblance is an external one, 
and that “there is no such relation between the representative 
forms as might be considered to be genetic. 55 The two groups in 
question belong to totally different families of fishes, and it will be 
observed, moreover, that not only the species but the genera of 
Trachinidse enumerated have, so far as we know them at present, 
a clearly circumscribed and definitely antarctic or subantarctic 
habitat.
