98 Mr. E. W. Oates on the 



after my friend Major Henry Jones, who has greatly assisted 

 me in studying and discriminating the various forms of 

 Silver- Pheasants. 



This species is found in the Shan States and Yunnan. The 

 Natural History Museum now possesses a large series. 

 The type specimen was sent to me by Capt. J. H. 

 Whitehead, who shot it at a place twenty miles east of 

 Kengtung (N. lat. 21° 30' and E. long. 99° 45'). He remarks 

 that it is not uncommon on the hill-ranges between the 

 Salween and Mekong Rivers. Colonel Rippon has sent five 

 specimens that he procured at an elevation of 5000-7000 feet 

 on Loi-Mai, a mountain situated in N. lat. 20° 30' and 

 E. long. 97° 30'. He has also sent three skins obtained by 

 Mr. H. N. Thompson at Trans-Salween Moukmai, which is 

 approximately in N. lat. 20° and E. long. 98° 30'. Capt. W. 

 G. Nisbett has recently presented a specimen to the Natural 

 History Museum which he shot at Pansibum, about forty- 

 five miles east of Bhamo, at an elevation of 7000 feet, while 

 he also notes that this bird occurs at Pumbum, about a 

 hundred and fifty miles north of Bhamo, on the frontier of 

 Yunnan, at an elevation of 7000 feet. Lastly, a Pheasant 

 brought home by Capt. A. W. S. Wingate from Yunnan, 

 south-east of Bhamo, is referable to this species. 



The male resembles that of G. nycthemerus, but differs 

 in the following respects : — The primaries are black, marked 

 with diagonal zigzag white bauds, which are narrower than 

 the intervening black spaces. The secondaries are diagonally 

 banded wiih black and v\ bite in about equal proportions. The 

 inner webs and the terminal half of. the outer webs of the 

 middle pair of tail-feathers are plain white, with the exception 

 of a few black specks under the coverts ; the basal half of 

 the outer web is marked w r ith narrow wavy black lines, 

 nearly parallel to the shaft. The bands on the upper plumage 

 are much heavier, being of about the thickness of a stout 

 hair-pin. 



In the male of G. nycthemerus the first primary is white, 

 marked on the inner web with three broad firm black lines
