O.N SOME NEW SPECIES OF SILVER-PHEASANTS 

 FROM BURMA. 



By Eugene W. Oates, F.Z.S. 



(Head before the Bombay Natural History Society on 

 25th January 1906), 



During the past twelve months I have received a considerable 

 number of Silver-Pheasants from some of my correspondents in Burma 

 and among them are three well-defined new species. 

 Gensleus prendergastt, sp. n. 



The adult male is entirely black except that the rump-feathers are 

 terminally fringed with sullied white or pale cream-colour and the 

 upper tail-coverts margined with white. Length about 24 inches ; 

 wing 9-2 inches ; tail 10*75 inches. 



The female is of an umber-brown colour, very finely vermiculated 

 with black, and each feather having a, pale shaft and a grey margin. 

 The wing-coverts are conspicuously tipped with white or pale rufous. 

 The four middle tail-feathers are of a chestnut colour ; the remaining 

 feathers are rufous progressively more and more suffused with brown, 

 the outermost feather becoming brown with a rufous tinge. Length 

 about 20 inches ; wing 8*4 inches ; tail 8 inches. 



The legs in both sexes are brown in the dried skins. 



Two pairs of this bird, which appears to be the ordinary common 

 Silver-Pheasant of Northern Arracan, have been sent to me by 

 Mr. 0. M. Prendergast, the Deputy Commissioner of the Arracan Hill 

 Tracts, and I have much pleasure in naming this species after him. 



GrENN^EUS MAODONALDI, Sp. n. 



The adult male has the crest black. The head, sides of neck, back 

 of neck, mantle, back, scapulars, wing-coverts and secondaries are 

 black closely and firmly vermiculated with white across the feather ; the 

 feathers of the mantle and back with dark metallic blue margins. The 

 rump is black, each feather broadly fringed with white and with several 

 very firm distinct white vermiculations separated from each other and 

 from the white fringe by black bands as wide as the fringe itself. Tho 

 primaries have the outer web mottled with white, the inner web plain 

 black. The two middle tail-feathers are black closely vermiculated with 

 white ; the others are black more or less vermiculated with white on 

 the outer webs, the inner webs being almost entirely black. The
