 November 17, 1928; one female, Khun Tan Mountains, 4,000 feet,

A male and female from Laos, one male from Tonkin, and a female

 siderably lighter below than the above Siamese series. The two 

 specimens from Laos and the male from Tonkin are in worn and faded 

 plumage, but the South Annam female is in unworn and fresh plumage. 

 The three Siamese females are much more buffy below than the male, 

 but the South Annam female is darker and more brownish, less 

 greenish above, especially on the head and back, and more grayish, 

 less buffy, below than even in the Siamese male. The difference 

 between it and the Siamese females is even more pronounced. 



The four specimens from Siam measure: Wing, 43-46 (44.6); tail, 

 20-24 (21.4); culmen, 9-10 (9.6) mm. The two from Laos, one from 

 Tonkin, and one from South Annam: Wing, 43.5-46.5 (45.7); tail, 

 19-22.5 (20.9); culmen, 8-9.5 (9) mm. 



The form ranges in the Himalayas from Nepal to Assam, south to 

 Burma, Yunnan, vSiam, South China, Laos, Tonkin, South Annam, 

 Tenasserim, Peninsular Siam, the Malay States, and Sumatra.

 Schauensee ^^ states that it is found commonly in the foothills and 

 occasionally up to 5,500 feet at Cliiengmai and Khun Tan.
