AKT. 5 BIRDS FROM YUNISTAN AND SZECHWAN^ CHINA RILEY 27 



Three additional races have been named from southeast Yunnan, 

 namely: Poinatorhinus ruficollis recvnditus Bangs and Phillips;^- 

 PomatorMnvs ruflcoUis laurentei La Toiiche; -^ and Pomatorliinus 

 ruficollis aZbipectus La Touche.^^ The United States National Mu- 

 seum contains no material from this region and so I am not able 

 to judge of the validity of the forms, but if they should prove to be 

 synonymous with P. r. hakeri, then Bangs and Phillips's name should 

 be used for it. 



S6. POMATORHINUS ERYTHROGENYS DEDEKENSI (Oustalet) 



Pomatorliinus maccleUandl, var. dedekcnsi, Oustalet, Ann. Sci. Nat. Zool., 

 ser. 7. vol. 12, 1892, pp., 276, 304 (Tibet and Tatsienlou). 



A fine series of adults and immatures from: Yiinglung, ISIarch; 

 Likiang Plain, 9,000 feet, April and August ; Likiang Mountains, 

 J 0,000 feet, April-August; Limestone Range, 10,000 feet, east of the 

 Likiang Mountains, July; Hofuping Mountains. Mekong Valley. No- 

 vember; Mountains near Yangtza, Mekong Valley, November; For- 

 ests of Youngning, northwest Yunnan Plain, February. 



There is considerable variation in this series. Early spring and 

 fall taken examples are much darker above, the sides and flanks 

 deeper, and the spotting below heavier than birds taken in the sum- 

 mer when wear and fading sets in. There is considei'able individual 

 variation, however, especially in the amount of spotting below. 



I have only a pair of birds from Shensi {P. e. gravivox) for com- 

 parison, the female smaller and darker than the male. These two 

 specimens average considerably lighter than birds in corresponding 

 plumage in the Yunnan series. It seems to me that Poniatorhinus 

 maccleUandi odicus Bangs and Phillips -° is only a synonym of 

 Oustalet's bird.

 20; between Tan Ten and Ssuching, March 24; Nguluko. 10,000 feet, 

 April 7 ; Likiang Mountains, 8,000-10,000 feet, June- August ; Li-

 compared with birds from central and southeast China.
