Adult Male. Above ashy grey, all the feathers of the upper part of the neck and iuterscapulary region 

 transversely barred with blackish ; the head crested, the feathers slightly tinged with rufous, the bases 

 of the long crest-feathers showing rather plainly, which gives them a blacker appearance ; a line of 

 feathers behind the eye, extending above the ear-coverts, white ; lores white, varied with black just 

 above the nostril ; a spot underneath the eye white ; cheeks white, slightly varied with blackish, 

 extending backwards and running down the sides of the neck, and forming a white band as far as the 

 scapulars; moustachial region and entire throat jet-black; scapulars rusty red, varied with black, 

 which takes the form both of broad bands and minute vermiculations, some of the feathers mesially 

 streaked with cream-colour, and most of them narrowly edged with fulvous, the outer feathers tipped 

 on the outer web with a broad spot of white, which forms a very distinct band running the whole 

 length of the scapulars ; lower part of the back, rump, and upper tail-coverts clearer ashy grey, less 

 varied with black, which only appears here and there in the form of an occasional narrow transverse 

 bar, a mesial streak, or a few obscure rnottlings and vermiculations, all the feathers obscurely edged 

 with very pale buff ; wing-coverts ashy brown, all of them more or less broadly margined with fulvous 

 or white, the least ones spotted and irregularly barred with fulvous, the median and greater coverts 

 very distinctly spotted with white ; quills brown, the primaries distinctly margined with fulvous along 

 the outer web, and slightly freckled with brown, the two outermost quills rufescent on the outer web, 

 alternately barred with brown, which gives it the appearance of a chess-board, the secondaries more 

 washed with ashy grey, tinged with rust-colour, and transversely barred with pale fulvous, all the 

 feathers more or less freckled with black, and the innermost or dorsal secondaries broadly edged with 

 black along the outer web, and with fulvous at the tip and on the inner web of the feathers ; tail- 

 feathers ashy grey at the base, very plainly freckled with black, the two middle feathers similarly 

 marked, but slightly tinged with rusty brown, and transversely crossed with irregular fulvous bars, all 

 the other feathers having a broad bar of black across the apical half of the feather, and tipped with 

 greyish white ; under surface of the body white, somewhat mottled with brown where the bases of the 

 feathers show through; the breast slightly tinged with rusty red, but the long flank-feathers very 

 distinctly marked with this colour, especially on the higher part of the flanks ; under wing-coverts 

 ashy brown, varied with spots and lines of white ; bill blackish horn-colour ; feet reddish brown, with 

 a shade of grey; iris nut-brown; eyelid rich red. Total length 12'5 inches, oilmen 08, wing 6 - 3, 

 tail 4" 7, tarsus l - 25. 



Obs. The above description is taken from a fine adult male in our own collection, killed in Norway in 

 January 1869. Another male, in Canon Tristram's collection, procured from Christiania in July, 

 shows that there is little or no change in the summer and winter plumage of this Grouse. In this 

 specimen the grey of the upper surface is a little purer, and there is a slight tinge of rufous on the 

 crown, ear-coverts, and sides of the neck. Total length 12 inches, culmen 0"8, wing 6*4, tail 4 - 7, 

 tarsus 1-25. Another specimen from Moscow, in Mr. J. H. Gurney's collection, obtained by him there 

 on the 11th of September 1869, has a decided fulvous tinge on the under surface, and the upper parts 

 not such a pure ash-colour; the tips of the tail-feathers are also entirely ashy, freckled with black.
