552 MR. R. SWINHOE ON NEW CHINESE BIRDS. [Apr. 16, 



patched with black ; winglet and primaries deep brown, the former 

 spotted with reddish chestnut, the latter on the outer webs and at 

 tips with brownish buff ; secondaries brown, with whitish margins 

 mottled with reddish buff, the tertiaries being yellowish brown with 

 pale margins mottled with black and with a black patch on each 

 outer web ; lower back and rump yellowish brown, mottled with 

 black and buff, the upper tail-coverts having central blotches of 

 black. The two central tail-feathers brownish grey finely mottled, 

 banded with seven obscure bars of darker brown, and terminating 

 with a black spot and white tip ; on the next feather chestnut occurs 

 at the base of the spot, and tinges the bar below it ; on the next 

 again the two terminal bars are chestnut ; and on those that follow 

 the chestnut occupies almost the whole extent of feather, ending 

 with a black bar and a conspicuous white tip. 



Fresh female shot towards end of December 1871. — Entire length 

 20 inches; wing 7:9; tail G"8, of sixteen feathers, the four centrals 

 equal and longest, the rest pretty equally graduated about half an 

 inch between each. Iris reddish brown ; bill ochreous horn-colour ; 

 legs light leaden, with pale claws. Tarse 2 - 5 ; middle toe and 

 claw 2-25. 



The same mountains have also yielded a Pucras Pheasant remark- 

 able for the absence of the golden neck-spot which adorns the 

 Pucrasia xanthospila of Northern and Western China (Mantchuria 

 to Szechuen). It is of the same model as the other two closely 

 allied species, P. macrolopha of the Himalayas and the above-men- 

 tioned, but differs sufficiently from either to be recognized as a third 

 race of this curious type. I propose to dedicate this discovery to 

 Mr. Charles Darwin. 



Pucrasia darwini, sp. nov. 



Male. — Head coloured as in the other two, but the bronze en- 

 croaching more on the crown ; central occipital crest yellowish brown, 

 with central yellowish streaks ; lower eyelid covered with minute 

 pure white feathers ; white spot on side of nape as usual. Feathers 

 of the hind neck white, delicately shaded over, and with four black 

 streaks converging to tip ; greyer on the back and rump, the lines open- 

 ing into mottling; some of those covering the rump having a V-mark 

 of black with pale yellowish centre and light chestnut shading. The 

 long uropygials and central tail-feathers greyish white, with a broad 

 margin of chestnut, flanked inwardly with black and outwardly with 

 narrow white. Rectrices pale French or K estrel grey, bordered along 

 the sides with black, edged with grey, and barred at the end with 

 black conspicuously tipped with white ; in the outer feathers the 

 black border is confluent with the bar, in the more central it is 

 broken by the grey extending across ; all have more or less black 

 about the basal two thirds of the stem. The two central tail-feathers 

 coloured like the tail-coverts, but clearer and brighter. Median 

 featbers of the underparts from the neck downwards deep chestnut 

 as usual, lighter and dingier on the abdomen ; lateral feathers reddish
