816 BIRDS. 
which is but a little larger than the Partridge, and is prettily varie- 
gated with brown and white, grey and red; a large black band near 
the tip of the tail; throat of the male black, and his head slightly 
tufted*. 
America produces some neighbouring species, such as 
Tet. canadensis and canace, L.; Gelinotte noire d’Amer., Enl. 
131 and 132; Edw. 118 and 71. Brown, verging more or less on 
a black; tip of the tail red. 
In some, the feathers on each side of the neck of the males are 
turned up like a mantle, or two scrolls: their habits have an affinity 
with those of the Turkey. Such are, 
Tetr. umbellus and togatus, Gm.; Cog. de Bruy. a fraise, Enl. 
104; Edw. 248; Wils. pl. xlix; called Partridge in New England, 
and Pheasant in Pennsylvania. Variegated with red, grey, and 
black: a large black spot at the bottom of the neck, on each side; 
a black band edged with white on the tip of the tail; lower part of 
the tarsi naked. Found in the mountain forests; the voice of the 
male in the nuptial season resembles the roll of a drum. 
Tetr. cupido, Gm., Catesb. Suppl. 1; Wils., pl. xxvii; Vieill. 
Galer. 219. (The Pinnated Grous). Variegated with brown and 
fawn colour; tail brown; tarsi feathered down to the toes; the fea- 
thers on the bottom of the male’s neck turn up into two pointed 
scrolls, beneath which is a naked skin, which, in the genial season, 
he inflates like a bladder; his voice sounds like a trumpet. Found 
on extensive plains, and is such delicious food that laws have been 
passed to preserve the breed}. The name of 
Lacorus. 
The Lagopede, Snow-Partridge, or Ptarmigan, is more particularly 
applied to those species which have a round or square tail; whose toes 
are feathered as well as the legs. ‘The most common become white in 
winter. 
Tetr. lagopus, L.; Lagopeéde ordinairet, Enl. 120-and 494; 
Brit. Zool. pl. M, 3, M, 4; Naum. Ist Ed. Supp. 61, f. 115, 116. 
(The Ptarmigan or White Grous, or Partridge of the Pyrennees). 
Its summer plumage is fawn coloured, marked with small black 
lines§. From high mountains, where it remains during the winter, 
in holes which it forms under the snow. 
* The Attagas of Buff., Attagen of Aldrov., Ornith., 1], p. 75; Gelinotte huppée, 
Briss., appears to me after much research, even in Italy, to be nothing more than a 
young or female Gelinotte., It is the same individual painted by Frisch., pl. exii. 
The Tetrao canus, Gm. (Sparm. Mus. Carls., p. 16) is only an albino variety of the 
Gelinotte. Neither have I any confidence in the authenticity of the T'etr. nemes- 
sianus, nor in that of the Tetr. betulinus of Scopoli. They are females, or the young 
of the Tetr. tetrix, or disfigured Gelinottes. 
+ Add, Tet. urophasianus, Bonap. III, pl. xxi, f. 2;—Tet. obseurus, Bonap. III, 
pl. xviii. 
t lLacopus—hare’s foot, hairy foot—is the ancient name of this bird. 
§ In this summer livery it is the Tetr. rupestris, Lath.
