286 Lloyd's natural history. 



Pucrasia xanthospila, var. ruficollis, David and Oustalet, Ois. 

 Chine, p. 408 (1877). 



Adult Male. — Like P. macro lopha, and especially P. meyeri, in 

 general appearance, but the arrangement of the colours on the 

 upper-parts, sides, and flanks is reversed, the shaft-stripes and 

 margins of the feathers being grey and divided from one 

 another by a black band ; a yellozvish-buff or rufous-buff nuchal 

 collar ; outer tail-feathers grey, with several black bands, the 

 widest near the tip. 



Adult Female. — Easily distinguished from the female of P. 

 macrolopha by the grey outer tail-feathers, barred with black. 



Range. — Mountain forests of North-western China, extending 

 into Manchuria and Eastern Tibet. 



Habits. — According to Abbe David the Yellow-necked Kok- 

 lass, or Song-ky (Pine-Fowl), is found in small numbers in 

 the wooded mountains of North-west China, and extends to 

 Manchuria and Eastern Tibet. They never stray far from the 

 underwood and jungle, where they are found solitary or in 

 couples, feeding on grain and various vegetation, especially 

 conifers. Their habits are like those of the True Pheasants, 

 and they are excellent eating, being much superior to the 

 other birds of the Pheasant-tribe met with in that part of 

 China.

Pucrasia darwini, Swinhoe, P. Z. S. 1872, p. 552 ; Elliot, 



Monogr. Phasian. i. pi. 30 bis (1872); Gould, B. Asia, 



vii. pi. 25 (1875) ; David and Oustalet, Ois. Chine, p. 409 



(1877); Ogilvie-Grant, Cat. B. Brit. Mus. xxii. p. 316 



(1893). 

 Adult Male.— Distinguished from the male of P. xanthospila 

 by having no yellowish-buff or rufous-buff collar, and the ground- 

 colour of the sides and flanks pale reddish-buff, though the dis- 

 position of the black marking on these parts and the mantle is 

 perfectly similar.
