Silver-Pheasants of Burma. 99 



parallel to the shaft. The black marks on the other primaries 

 are oblique and broken, and occupy only one-third of the 

 feather, the remaining two-thirds being white. On the 

 secondaries the black markings occupy only one-quarter of 

 the feather, the remaining three-quarters being white. The 

 two middle tail-feathers are entirely white, with the exception 

 of a few narrow black bars under the coverts. The bands 

 on the upper plumage are much finer, being of about the 

 thickness of a small pin. 



The females of the two species are totally different. In 

 G.jonesi each feather of the lower plumage is black and has 

 a spearhead-shiped white shaft-streak and a submarginal, 

 somewhat V-shaped, white band near to, and following, the 

 margin of the web. The tail-feathers are banded with coarse 

 oblique bars of black, brown, and pale buff. 



In G. nycthemerus the whole plumage of the female, both 

 above and below, is umber-brown with pale shafts to the 

 feathers ; there are none of the conspicuous white marks on 

 the lower plumage which are to be found in G.jonesi. The 

 tail-feathers are finely vermiculated, not banded, with black, 

 brown, and white. 



A fine male of G.jonesi measures 40 inches in length ; 

 wing 11*5 inches ; tail 25 inches. The legs are bright red; 

 the skin of the face is scarlet ; the irides are hazel and the 

 bill is of a greenish colour. 



A female measures about 25 inches in length ; wing 10 

 inches; tail 11 inches. 



4. GenNjEus msbetti, sp. nov. 



It is not always safe to describe a new species from an 

 incomplete skin, but in this particular instance a specimen of 

 a Silver-Pheasant, consisting of the skin of the back and 

 rump, the wings, tail, and feet, sent by Capt. W. G. Nisbett, 

 indicates a species totally different from any known to me. 



This bird, a male, was procured in the Kachin Hills, five 

 miles east of Sadon, at an elevation of 2500 feet. Sadon is 

 a police-post close to the Chinese frontier and some forty
