This agrees with specimens from western Szechwan and western 

 Tunnan; no specimens from Nepal have been available for comparison. 



This form breeds in the mountains of Szechwan and Yunnan, China, 

 Nepal, Assam, Tonkin, and Siam. It is probably resident where 

 found. Apparently there are no other Siamese records.
