Birds of Southern Tibet. 75 



can be separated into two divisions according to the colour 

 of the supercilium. In Chinese birds this appears to be in- 

 variably of a rich buff colour, whilst Indian and Burmese 

 examples have the superciliary streak almost white. The 

 Khamba Joug specimen belongs to the latter series. 



Although I shot a great many Willow- Warblers during the 

 summer in Tibet, the specimen from Khamba Jong was the 

 only one that I procured.

 Bill blackish horn-coloured, lower mandible and gape yellow ;
