Parus major altarum, subsp. nov. 



Differs from Parus major artatus Thayer & Bangs of 

 Central and North China by its larger size, wide black shaft- 

 stripe on central rectrices, and much whiter side-rectrices. 

 In North China, East and Central China birds, the white on 

 the penultimate rectrix is^ at the most, of slight extent, 

 generally very small and sometimes almost invisible ; the 

 shaft-stripe of the central rectrices is in these birds very 

 variable and of not much importance. In the Yunnan birds, 

 this shaft-stripe is always well marked and generally wide 

 or very wide, the outermost pair of rectrices is mostly white, 

 and the penultimate pair has a large wedge of white at its 

 extremity, which varies from 18 to 35 mm. in length. The 

 next two pairs have a white terminal speck of greater or less 

 extent, and often the whole tail is tipped with white.

Parus tibetanus Hartert is said to have a very white tail, 



but is a larger bird, measuring 78 mm. 



Corvus corone yunnanensis, subsp. nov. i 



The S.E. Yunnan Carrion-Crow differs from the N.E. 

 Chihli (Chinwangtao) bird in having a much more- slender 

 and less convex bill. The feathers of the mantle are shot 

 with green, the upper breast-fe;ithers are more lanceolate, 

 and the underparts are less glossy.

This Crow is resident at Mengtz and also, I believe, on all 

 the plateaux as far as Yunnan-fu (alt. 4000-6000 ft.). 



The bird found in N.E. Chihli has a stout, rather convex, 

 and short bill, the mantle is shot with violet-blue, and the 

 breast-feathers seem more rounded than in the Yunnan bird.
