BIRDS FROM SIAM AND THE MALAY PENINSULA 385 



males, Doi Hiia Mot, August 24, 29, 1934; one male and one female, 

 Ban Ta Pai, December 23, 1932. 



Kloss,*^ trusting to memory, thinks vividus Baker is a synonym of 

 flavescens Blyth. Only one specimen of X. f. jlavescens Blyth from 

 Assam and one of X. j. sordidiis Robinson and Kloss from southern 

 Annam have been examined, and they are both quite distinct from 

 the northern Siam form. Under the circumstances it is advisable to 

 leave the latter where previous authors have placed it for the present, 

 under Stuart Baker's name. X.J. vividus is a brighter, more yellowish 

 bird on the breast and belly. 



Tw^o of the males from Doi Hua Mot are immature, but have nearly 

 acquired the adult plumage; the squamate feathers are coming in on 

 the forehead and crown. 



The form ranges from the Kachin Hills, Shan States, and south- 

 eastern Burma to northern Siam. 



Williamson *^ records it from Doi Nga Chang, Lampang, and de 

 Schauensee ^* secured it on Doi Sutep and later at Chiengdao and 

 Khun Tan.
