12,000-13,000 feet, November-December ; Lautsolo Gorge, 9,000 feet, 

 April; Luddii Mountains, 12,000-13,000 feet, August) ; two females 

 from southwest Szechwan (Vudju Mountains, 10,500 feet, May). 



This very distinct species resembles Sitta villosa of north China 

 in general appearance, but there are numerous differences. ;S', yun- 

 nanensis has a black line on the side of the head from the lores 

 through the eye to the nape with a narrow white superciliary above 

 it, the pileum bluish gray, while in the fully adult male S. villosa the 

 whole top of the head is black with a white superciliary ; the latter 

 is a smaller bird. 



The tail of S. yunnanensis is somewhat variable. The white on 

 the outer tail feathers is reduced to a mere subterminal spot on the 

 inner web in some specimens, while in others it is a narrow diagonal 

 subterminal bar, extending across the feather.
