ART. 5 BIRDS FEOM YUNNAN AND SZECHWAN, CHINA KILEY 25 



92. TROCHALOPTEnON STYANI Oustalet 



Trochalopicron styani Oustalet, Bull. Mus. Paris, vol. 4, 1898, p. 226 

 ( Ta-tsien-lou, Szechwan ) . 



One male, mountains near Yangtza, Mekong Valley, November; 

 two females, Plofujoing Mountains, Mekong- Valley, November; one 

 male and one female, Tseh Chung, Mekong Valley, November, 



These speeeimens are so very different from the plate of Trocha- 

 lopteron cinereiceps Styan ^^ that it seems to me that to sink styani 

 to only a race of that species is to more or less obscure these funda- 

 mental differences. The differences have already been pointed out 

 by Hartert.^*^ 



93. lANTHOCINCLA MAXIMA (Verreaux) 



Pterorhinus maximus Verreaux, Nouv. Arch. Mus. Paris, vol. 6, Bull. 

 1870, p. 36, pi. 3, fig. 1 (Mountains of Chinese Tibet). 



A good series of both sexes from Likiang Mountains, 10,000- 

 12,000 feet, April to August; Litiping IMountains, Mekong- Yangtze 

 Divide, October; Hofuping Mountains, Mekong Valley, November; 

 Mount Dyinaloko, 11,500-12,000 feet, April and June; Mountains 

 near Yangtza, Mekong Valley, November; forest of Mill, S. W. 

 Szechwan, February. 



Some specimens have the feathers of the throat and chest with 

 subterminal black bars, while in others these bars are only faintly 

 indicated on the sides of the chest. The upper back has the ter- 

 minal spots buffy or white, with the latter predominating in the 

 series. Winter specimens are darker below than those taken in 

 summer. 



94. lANTHOCINCLA BIETI Oustalet 



lanthooincla bieti Oustalet, Bull. Mus. Paris, vol. 3, 1897, p. 163 (Tatsien- 

 lou, Szechwan). 



Five males and three females from Hofuping Mountains, Mekong 

 Valley, November; and Litiping Mountains, Yangtze-Mekong Di- 

 vide, 12,000 feet, November. 



Rothschild ^^ in commenting upon specimens from the same gen- 

 eral region says that they differ somewhat from the original 

 description but does not mention in what particular. Below a 

 description is given for future comparison : 



Above antique brown, becoming sudan brown on the pileum ; each 

 feather above from the nape to the tail with a subterminal black bar 

 and white tip ; lores, region around the eye, and upper and posterior 

 border of ear coverts white ; a narrow line of blackish bordering the
