The original of our domestic species is probably 

 the Javanese Fowl (6r. JSankivus) ; but many species 

 very much resembling ours are scattered about the 

 Continent and Archipelagoes of Asia. They have 

 many of the habits and manners of the domestic 

 races, joined to extreme shyness and wildness. 



Tetrao,* the Grouse. 



The name of this large family of birds, which Lin- 

 naeus made to include the Partridges and Quails, is 

 now restricted to the species inhabiting northern cli- 

 mates, having a round or forked tail, and feathered 

 feet. Above the eye is a patch of naked skin of a 

 scarlet hue. The Capercailzie (T. Urogallus}^ is as 

 large as, if not larger than, the Turkey. This noble 

 Grouse, sometimes called the Heath-cock, and the 

 Cock of the Woods, was at no very remote period 

 an inhabitant of our own island, and even now is com- 

 mon in Sweden and Norway. America produces 

 another, not inferior, the Cock of the Plains (T. Uro- 

 phasianus) , distinguished by having twenty feathers 

 in the tail. The Ptarmigan (T. Lagopus\ an inhabit- 

 ant of snow-covered plains, is feathered to the claws, 

 and becomes pure white in winter, as do some allied 

 species in North America.
