94 Mr. E. W. Oates on the 



interesting. Where the males of two species are super- 

 ficially alike and might be confounded, as in G. sharpii and 

 G. rufipes, we find that the females are totally different. 

 Again, where the females of two species are so alike as to be 

 barely distinguishable from each other, as in G. sharpii 

 and G. lineatus, we find that the males are wide apart. The 

 same holds good with the four Himalayan species, viz., G. albi- 

 cristatus, G. hucomelanus , G. melanonotus, and G. horsfieldi, 

 in which the males can be recognised at a glance, but the 

 females cannot be separated with any certainty. 



Many persons examining the males of G. nycthemerus and 

 my new species, G.jonesi, might refuse to consider them as 

 distinct. The great difference in the females of the two 

 species would, however, speedily convince them to the 

 contrary. 



Of the numerous species of Gennmts now recognised, I do 

 not know any two which resemble each other as regards 

 both sexes. Either the males or the females are strikingly 

 different. 



I now proceed to give a key to the males of all the Burmese 

 Silver-Pheasants, twelve in number, and a sufficiently detailed 

 account of each species. 1 do not attempt to give a key to 

 the females, as some of them arc not known. 



Key to tli e Males. 



a. Legs deep red. 



a'. Upper plumage marked throughout with lines 



parallel to the margins of the feathers, each 



pair wide apart at the base and meeting on the 



shaft, forming a spoon-shaped figure. 



a". Ear-coverts and the whole of the sides of the 



neck heavily pencilled with scale-like marks. 



a'". Tail up to 12 inches. Either two or three 



pairs of black lines on each feather of the 



upper plumage, these being broader than 



the white interspaces G. andersoni. 



b'". Tail up to 20 inches. Either four or five 

 pairs of black lines on each feather of the 

 upper plumage, these being about equal 

 to the white interspaces G. rufipes.
