Lower mandible_, legs, feet and claws whity brown ; upper mandible 
darker, but still pale brown ; irides creamy yellow. {Davison.) 
Length 6 inches, tail 2*8^ wing 2'5^ tarsus '9, bill from gape '75. 
This species is hardly more than a race of S. cyanuroptera of the 
Himalayas. It differs principally in wanting the white tip to the winglet, 
in having the upper plumage brown instead of ferruginous or reddish 
brown, and in not having the quills so richly coloured. 
My description is taken from a specimen procured in Karennee by 
Capt. Wardlaw Ramsay. It appears to differ from Tenasserim specimens 
(judging from the descriptions only of these) in some particulars, and to 
be in many respects intermediate between S. sordida and S. cyanuroptera. 
The Burmese Blue-winged Hill-Tit was obtained in Karennee by 
Capt. Wardlaw Ramsay, and in Tenasserim by Mr. Davison on the higher 
slopes of Mooleyit mountain. 
Nothing is on record about the habits of this species. According to 
Dr. Jerdon, its ally, S. cyantLroptera,!^ found in considerable flocks, with 
a hurried and lively manner, flying from tree to tree, alighting about the 
middle, and then hopping and climbing up to the topmost branches, 
hunting for minute insects with a lively chirrup. According to Mr. 
Hodgson, the nest of >S^. cyanurop tera is a large compact cup made of moss 
and leaves and lined with grass ; it is placed in trees, at no great elevation 
from the ground. The eggs are either three or four, greenish spotted 
with brownish red.
