ART. 7 BIEDS FEOM YUNISTAN AND SZECHWAIST, CHIISTA EILEY 27 



Two males and two females, Ndamucho, 14,000 feet, northwest 

 Yunnan, October. 



LaTouche ^^ unites dauuricus and fuscicollis as other authors have 

 done, but admits that he has no proof that they are the same and 

 presents evidence for and against such a view. It is quite possible 

 that the black bird, fuscicollis^ and the pied, dauuHcus, are only 

 phases of the same species, but until this is proved to be undoubtedly 

 the case the records had, in my oj)inion, better be kept separate. If 

 the two are only color phases, it is rather queer that intermediates 

 apparently are never or rarely found. 



Stresemann -* has called attention to the precedence Vieillot's name 

 has over that of Schlegel. Lord Rothschild ^^ regards the present 

 bird as a dimorphic form of dauuricus.

Conostoma aemodius Hodgson, Joul'ii. Asiat. Soc. Bengal, vol. 10, p. 857, 1841 

 (Nepal). 



Two males, six females, and one unsexed, Ndamucho, Yangtze- 

 Mekong Divide, 14,000 feet, northwest Yunnan, October. 



No specimens are available from the Himalayas or western Szech- 

 wan. The present series is referred to the above race on geographic 

 grounds, rather than to C onostoma aemodium tmiibuseti Strese- 

 mann -" from Waslian, Szechwan. Since the above was written an 

 adult male has been received from the Rev. David C. Graham taken 

 in Mupin. It is somewhat darker below and on the occiput; the 

 differences are not great, however. 



The two males from Yunnan measure : Wing, 138.5-139 mm. ; tail, 

 140-144; culmen, 26-26. The six females from Yunnan: "Wing, 

 125.5-137.6 (131); tail, 137.5-145 (141.9); culmen, 22.5-25 (24). 

 The single male from Mupin: Wing, 123.5; tail, 132; culmen, 22. 



This would seem to indicate that the more northern bird is some- 

 wliat smaller, but one specimen, sexed by a native, is not sufficient to 

 pass judgment on the validity of a race.
