ART. 7 BIRDS FROM YUNNAN AND SZECHWAN, CHINA RILEY 63 



Szechwan, August; one adult, Fuchuanshan, 10,000-12,000 feet, 

 Yunnan, September. 



The wing of the adult male measures 53.5 nun. Two males 

 from the Likiang Mountains, Yunnan, taken in May and August, 

 measure: Wing, 54-55.5 mm.; one male, apparently of this race, 

 from near Ningyuanfu, Szechwan, has the wing 50 mm. This is a 

 slight extension northward of the breeding range. Just where the 

 present race meets valeritini is not known; the United States Na- 

 tional Museum has breeding specimens of the latter from Mount 

 Omei, near Washan, and Wenchwan, Szechwan, but they are prob- 

 ably not typical, as the wing measurement is not so great as that 

 given by Bangs for the form.^' Breeding birds are much lighter 

 below than before the breeding season. 



184. SEICIRCUS BURKII VALENTINI (Hartert) 



Cryptolopha burkii ralentint Hartekt, Die Vcigel der palaarktisclien Fauna, vol. 

 1, Heft 4, p. 497, 1907 (Taipaishan, Shensi). 



Three males, one female, and one unsexed, Likiang Mountains. 

 Yunnan, October. 



These are evidently migrants from the north. Two of the adult 

 males have a wing measurement of 63 and 61 mm. ; the female, 57 

 mm. The foreheads of all are tinged with yellowish green. 



185. PHAEORHADINA FUSCATA ROBUSTA (Stresemann) 



Phylloscopus fuscatus robustu-s Stresemann, Abh. Ber. Mus. Tieik. Volkerk. 

 Dresden, vol. 16, no. 2, p. 16, 1924 (Sungi^an, Szechwan). 



One male, Weihsi, 8,000-9,000 feet, northwest Yunnan, September, 

 This specimen is darker above and paler below than the form 

 that migrates through eastern China. It is a bird of the year; the 

 belly slightly tinged with very pale yellow and may not belong here 

 at all, but I do not think it belongs with the east China form 

 {fuscata). 



186. PHAEORHADINA AFFINIS (Tickell) 



Motacilla afflnis Tickell, Joiu*n, Asiat. Soc. Bengal, vol. 2, p. 576, 18.33 (jungles

 wan, April.
