Tins Wood Grouse is a native of Kortlieru Russia, Sihcria, and Kamtscliatlca, and is fully described by Middendorf in the Avorlc above 
referred to. lie .says; “Pallas notices that Messrs. Sclunidt had distinguished a smaller variety of Wood Grouse; Steller, on his part, I find, 
affirms that the Wood Grouse of Kamtschatlca were obviousl}'^ smaller than those of Siberia and Russia. These statements are explained 
by the fact that in Siberia T have met Avith two varieties of the Cock-of-th e-Wood, i. e., the one considered as typical in Europe, and a 
smaller variety or species living in the mountainous regions; and this latter appearing to be the only one existing in Kamtschatka. * * * 
Our species has several distinguishing characteristics, which we Avill review in order. First, in regard to the male. It is considerably smaller 
than the Bui’opean Coek-of-the-Woods, the full-grown bird weighing probably not more than pounds at the highest estimate. This small 
size is very apparent on a comparison of the bills and the toes. The folloAving measurements of a large male of the typical form, and of 
the Tetrao Ph’ogalloides of the StanoAvoj Mountains shorv the ditference existing :

“By this the great difference in the bill of the two forms Avill be seen. NotAvithstauding this, the difference in the size of the Avbole 
body is not very great, for on aceomit of the proportionately longer tail of Tetrao UrogaIloide.s, its entire length is ecpual to that of Tetrao 
Urogallus. With this last species, the tail Avbcn laid on the back generally reaches to the beginning of the neck ; with the other, hoAvcver, it goes 
to the back of the head. This is in consequence of the length of the middle feathers, which gh'e to the tail a AA^edge shape. 
“ The upper parts of Tetrao Hrogalloides are ahvays covered with AAdiite spots : and those tipon the upper coyerts of the Avings and tail are 
characteristic of this species.” * 
There is a ftue example of a male of this species in the British ]\rusemn, Avith even more white spots upon the AAnugs than were upon those of 
the specimen figured in my plate ; and in the Paris Museum a very avcII preserved female. This last resembles closely the female of Tetrao 
Urogallu,s, but the wings and back were very much spotted and marked with Avhite. 
This species resembles in some degree its near relative, the Tetrao Urogallus, but may easily bo distinguislied from it by the rows of white 
spots upon the wings, and also sometimes on the back, its small size, and wedge-shaped tail. 
The figures are about three-fourths the natural size.
