districts. 
Length 23, breadth 34 inches ; weight 48 ounces. Bill black. Irides hazel. A 
bare scarlet granulated spot over the eye. Head, neck, and body, glossy black, 
with a bluish tinge. Quills 26, the four first black, the others white at the bot- 
tom forming a white bar on the wing. Under coverts white. Tail of 16 fea- 
thers, nearly 7 inches long, square at the ends, the two or three external ones, 
on each side, 4 inches longer than the others. Under coverts white. The female 
is less, of a brown colour, barred and mottled with black, and the lateral tail- 
feathers are but little produced, and not recurved. Eggs 6 or 7, dirty white, 
with brown blotches. The young follow the mother. Food, consists of moim- 
tain-berries, heath, and birch-tops, and even corn. Dr Walker found the sto- 
mach stuffed with the leaves of Polypodium vulgare., after the bird had lived in 
woods during winter, (Hebrides, i. 337-) In Russia, this species is caught by 
“ stakes, pointed at both ends, driven into the ground, approaching near each 
other at the bottom, but diverging at the top, so as to resemble a funnel or in- 
verted cone. To the top of each stake is tied an oat-straw, with the grain on 
it. A long stake stands up in the middle of this machine, likewise crowned 
with oats. To this is attached a horizontal stick, vacillating freely within the 
cone. The birds come to eat the oats, and light on this stick. It gives way, 
and lets them fall into the cone, where not being able to use their wings, 
they remain prisoners.” (Mem. Acad. Imp. des Scien. Peter, i. 189. p. 321. 
(Annals, of Phil. iii. 223.) 
It may be proper to take some notice in this place of a bird, long considered 
as a hybrid between the cock of the wood and the black-cock. It is the T. 
hybridus of Sparman, (Mus Carls, fasc. i. tab. 15.) T. intermedius of Langs- 
dorff, (Mem. Acad. Peter, iii. 181 1, p. 236.) The Tetras rakkelhan of Tern. Orn. ii. 
p. 459. In this species the feathers of the throat are a little produced ; head, 
neck and breast, black, with bronze and purple reflections ; back and rump 
with ash-coloured dots. Length 27 inches. The female is unknown. This 
species is noticed as a native of Scotland by Brisson, under the name of Le 
coq de bruyere piquete, and a Scottish gentleman told Dr Tunstall, who in- 
formed Dr Latham, that it existed in our woods. The subject merits atten- 
tion.

and by the third year is no longer a mark of distinction. Eggs from 12 to 20,
