bring them under the fame fpecies, for it is 
known that the males of all the grous tribe, 
and indeed of mod: of the gallinaceous birds, 
are ufed to ftrut in a very ftately manner, and 
that the colours of their plumage are much 
more diftindt than thofe of the females. But 
the fpecific difference alone, which Linneus 
aftigns to the cock of the wood, abfolutely 
excludes our Hudfon’s Bay fpecies ; he calls 
it Tetrao pedibus hirfutis, cauda rotundata, 
axillis albis. Whoever examines Mr. Ed- 
wards’s figure, and the fpecimens now in the 
Society’s pofteffion, will find the tail very 
fhort, but pointed, the two middle feathers 
being half an inch longer than the reft, (Mr.. 
Edwards fays two inches) and the axillae, or 
fhoulders, by no means white: befides this 
difference, the colour and fize of the Hud- 
fon’s Bay bird are likewife vaftly different 
from thofe of the cock of the wood. Its length 
is 17 inches, its breadth 24, and, as Mr. 
Edwards juftly fays, it is fomewhat bigger 
than the common pheafant. The great cock 
of the wood is as big as a turky ; and 
its female, which is much lefs, however 
far exceeds our bird, it being 26 inches long, 
and 40 broad. See Britifh Zook ocftavo, 
p. 2co. The figures given of the fe- 
male of the T. Urogallus, or great cock of 
the wood, in the Br. Zool. folio, plate M 
and the Planche enluminee 75, will ferve 
upon companion as a convincing proof of 
the vaft difference there is between the Hud- 
fon’s Bay pheafant grous and the European cock
