a) ef 1^/8 b) 1^8 1902 Baimgol. 



c) ? ^/8 d) i^/s 1902 Baimgol. 



e) 9 1-^/8 f) 1^/8 g) 18/8 1902 Baimgol. 



Specimens a — d. have black horse shoe-marks on their 

 breast although less developed in the females which latter also 

 are less buff on breast and chest. These females are in moult. 

 The new feathers on the hind neck and upper back have 

 a ground-colour of (hoary) grey with black vermiculations while 

 the old feathers are more sandy brownish. On the middle 

 and lower back the ground colour of the new feathers is sandy 

 brown, not quite as påle as in the males which appear to 

 have finished their moult long ago. 



Specimens e — g are young without any buff on the breast 

 and also without an}^ trace of the black horse-shoe mark. 

 They are partly in moult. The rufous buff of the forehead 

 is narrower t han in the adult. On the throat and cheeks the 

 new buff feathers appear to replace the whitish or light sand- 

 coloured feathers (with light shaftstripes) of the chick. The 

 grey on the hind neck is not so much developed as in the 

 adult but it is due to the new feathers w^hicli also show the 

 chestnut subterminal bar. The old feathers of the chick 

 seem to have been sand-coloured with whitish shaft-stripes, 

 on either side bordered with dark. On the whole these 

 young birds have otherwise assumed a plumage similar to 

 that of the old hens.

 subspecies of Lyrurus tetrix, specimens of which I had bought 

 from a dealer the winter before. It was stated that these 

 specimens were from the interiör of Asia and they were la- 

 beled »Baimgol». In the geographical works and maps then
