The following specimens are all hybrids : — 



Gennceus haringtoni=:G. nycthemerus rufipes'^horsfieldi. Type. 



Gennceus andersoni=G. n. rufipes'^Tiorsfieldi. 



This bird is exactly the same as the specimens called haringtoni hj Oates. 

 (Type in Indian Museum, Calcutta.)

Types \ " ^ 



Both these birds were shot by Nisbett at Puntun, S.-E. oE Sadon. They 

 are the birds mentioned by Oates as being his types of the species, 

 although he has not noted this on the labels. 



All three of these so-called species, liaringtoni, nndersoni, and 

 granti are hybrids between rufipes and horsfieldi ; they vary somewhat 

 mter se, but the nycthemerus cross is the dominating one, especially in 

 granti. Hybridization is shown distinctly by the patchy colouration, and 

 it is moat interesting to note that in all these hybrids the barring of 

 the rump in contrast to the rest of the upper plumage is distinct, though 

 faint. In fact here in the extreme North-East of the Silver Pheasant's 

 habitat hybridization has evolved a specimen very much like a pale 

 cuviei'i or dark oatesi in the West. 



All these hybrids are red-legged birds. 



GenncBus nisbetti = G. n. rufipesy-horsjieldi. 



Type Gates' Coll., No. 99. 



This species is named from the remnants of a skin only, and it is not 

 easy to say whether it is a specimen of rufipes pure and simple, or a hybrid, 

 but traces of unevenness in the marking incline me to the latter opinion. 



Gennceus lineatus. Museum No. 1900.12.12.946, shot on the Eastern 

 frontier of Bhamo, is a hybrid between nyctheremus rufipesy-horsfieldi.
