Suthora webbiana ynnnanensis, subsp. nov. 



Near S. w. alj^Jionsiana of Kweichow, but with the sides 

 of the head and neck never pale grey, but dull greyish vinous 

 or dull greyish washed with vinous. Bill of birds in my 

 collection much larger. Five examples of Suthora in B.M. 

 collection from Yunnan province (Styan collection) are very 

 similar and without doabt belong to this Yunnan form, but 

 have the small bill of the Kweichow bird.

Sitta europssa obscura, subsp. nov. ^ 



Nearest to S. e. nagaensis, but with much darker dirty 

 brownish-grey underparts. It also approximates to 8. e. 

 montium, but, unlike that form, it has no pure grey on the ^j^-c h 



flanks, the underparts being uniform, and there is no seasonal . 



change of plumage. The bill is stouter than in S. montium, 

 but less so than in S. nagaensis. 

 . S . Wings 78-80 mm. ? . Wing 76-78 mm. 



Bill blackish, base of lower mandibles bluish, legs reddish- 

 brown. 



Type. S , Mllati, S.E. Yunnan (5000 ft.), 9 Jan., 1921. 



Obs. This is certainly the same bird as the one from Lou- 

 koucliai identified by Bangs and Phillips as Sitta europcea 

 montium. 



Zosterops aureiventer joannsB, subsp. nov. 



Near Z. aureiventer Hume, but the yellow stripe down the 

 centre of the underparts joins the yellow throat and is often 

 only slight in extent in some males and is absent altogether
