BIRDS FROM SIAIM AND THE MALAY PENINSULA 437 



February 8; Kloss ^ from Lat Biia Kao and Koh Lak; Robinson and 

 Kloss ^ from Tapli, Pakchan, March 11, Hat Saniik, April 18, and 

 state that WilHamson has examples from Nong Kae and Langsuen 

 taken in November and January; de Schauensee ^ took a single speci- 

 men at Cliiengmai, 5,000 feet, February 27. 



This species breeds in Amurland and migrates south late in summer 

 through China to Indo-Ciiina, Burma, Siam, and the Malay States 

 to winter. 



It is easily distinguished from the other members of the genus 

 wintering in Siam by having a yellowish supercilium, by the brownish 

 head with only a slight greenish tinge, the more brownish (saccardo 

 olive) back, the rump with a slight russet tinge, the feet in the skin 

 are light colored. 



SEICERCUS BURKII TEPHROCEPHALUS (Anderson) 



Culicipeta tephroccphalus Anderson, Proc. Zool. Soc. London, 1871, p. 213 

 (Bhamo, Burma). 



One male, Khun Tan, 3,000 feet, February 26, 1932; one male, 

 Muang Pai, December 28, 1932. 



I am not sure that these two specimens belong to one and the same 

 race; the Muang Pai male has the back a brighter, more yellowish 

 warbler green; the coronal median stripe broader and a lighter gray; 

 and the lowerparts a slightly brighter yellow. If not this race, how- 

 ever, I do not know what to call it. The wing in the Khun Tan male 

 measures 56; in that from Muang Pai, 51.5 mm. 



The form breeds in the mountains of Burma from the Chin Hills to 

 the Shan States; in winter it migrates to northern Siam, Laos, northern 

 Annam, and Cambodia. In Siam it has not been recorded often. 



Gyldenstolpe * records it from Kao Plyng, January 27, and on his 

 second trip to Siam he secured it at Khun Tan, September 9.^ De 

 Schauensee ^ took it at Doi Sutep, 4,500 feet, December 7 and 28, 

 and at Chiengsen, January 8 and 10; and on his third expedition he 

 secured a small series from the follov/ing localities: Chiengmai, Khun 

 Tan, Chieng Dao, and French bank of the Mekong opposite Chieng- 

 sen, December 20 to March 2.^ Deignan states that it occurs at 

 Chiengmai and Doi Sutep at 2,000-3,500 feet from October to April.
