THE COCK OF THE PLAINS.

Mountains, and also on the Columbia River. A 
figure was fii'st given of it by Bonaparte, from a spe- 
cimen in the possession of Mr Leadbetter. Both 
sexes were again figured in Mr Wilson's Illustrations 
of Zoology, and an excellent representation of the 
male is given in the Northern Zoology. 
The total length of the male is thirty-one and a 
half inches, that of the female twenty-two. The 
colour of the plumage is a beautiful mixture of yel- 
lowisn-orown, mottled and varied with deeper tints, 
the under parts nearly white, with longitudinal streaks 
of brown, and the centre of the belly dotted with 
large black patches. On each side of the breast are 
two round naked protuberances, placed farther for- 
ward than those of T. cupido, or pinnated grouse. 
Above each there is a tuft of feathers, having their 
shafts considerably elongated, naked, and tipped with 
black radii. On the sides of the neck and across the 
breast, below the protuberances, the feathers are short, 
rigid, and sharp-pointed, but lie over each other with 
the same regularity as the scales of a fish. The tail 
is eleven inches long, each feather lanceolate, and is 
gradually attenuated to a fine point. The female has 
the whole of the upper plumage umber-brown and 
yellowish-white, barred or mottled in equal propor- 
tions. Under part nearly as in the male, but with- 
out the projecting stiff feathers. 
The description of the manners of this species by 
Mr Douglass, is the best account we yet have. 
“ The flight of these birds is slow, unsteady, and af- 
fords but little amusement to the sportsman. From
