They may be divided into the following sub- 

 genera : 



The Grous, Tetrao, Lath. 



Whose legs are covered with feathers, and are with- 

 out spurs. 



Some of them, which more particularly retain this 

 name, have the tail round and forked, and the toes 

 naked.

 GrouSy Lath. Teti'ao Urogallus, L. Enl. 7^ and 74. 



The largest bird of this order, bigger than the 

 Turkey, slate coloured, finely striped across with 

 black. The female fulvous, with transverse brown 

 or blackish lines. It inhabits the great woods in 

 high mountains. It builds in heath or new cop- 

 pices, and feeds on birds and berries. Its flesh is 

 excellent. The windpipe makes two bends, before 

 it descends into the lungs.*
