TETRAO, Latham. 



The feet of Grous are covered with feathers, and are without spurs. Those 

 to which this name is more particularly applied have a round or forked tail 

 and naked toes. 



In some the feathers on each side of the neck of the males are turned up 

 like a mantlet, or two scrolls : their habits have an affinity with those of the 

 turkey. Such are 



Tetr. umbellus and togatus, Gm. ; called Partridge in New England, and 

 Pheasant in Pennsylvania. Found in the mountain forests. 



Tetr. cupido, Gra. (The Pinnated Grous.) Variegated with brown and 

 fawn colour ; tail brown ; tarsi feathered down to the toes ; the feathers on 

 the bottom of the male's neck turn up into two pointed scrolls, beneath which 

 is a naked skin, which 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 them. The name of 



LAGOPUS, 



Or Ptarmigan, is more particularly applied to those species which have a 

 round or square tail, and whose toes are feathered as well as the legs. 



Tetr. albus, Gm., called of Hudson's Bay. (The White Ptarmigan.) 

 From the whole north ; is larger, and its summer plumage more red ; its belly 

 remains white. 



PERDIX. Brisson. 







Partridges have the tarsi naked like the toes. Among them the 



FRANCOLINL-S, Temminck, 



Is distinguished by a longer and stronger beak, a larger tail, and, generally 

 speaking, by stout spurs. 



COMMON PARTRIDGES 



Have a somewhat weaker beak ; the spurs of the males are either short, or 

 mere simple tubercles; they are deficient in the female. 



CoTURNlX. 



Quails are smaller than Partridges, with a slenderer beak and shorter tail ; 

 no red eye-brow nor spurs. 



THE PARTRIDGES AND QUAILS OF AMERICA 



Have a stouter, shorter, and more convex beak; the tail is somewhat larger. 

 They perch on bushes, and, when disturbed, even on trees. Several of them 

 migrate like the quails of Europe. There are some other subgenera. 



TINAMUS, Latham, 



Or the Tinamous, is a genus of American birds, very remarkable for a 

 slender and long neck (although their tarsi are short), covered with feathers, 

 the tips of whose barbs are slender and slightly curled, which gives a very
