276 On neiv Species of Birds from Kan-su. 



Specimens M'ere obtained near the village of Satani in 

 November, the village of Yo-dzam-pu in June, July, and 

 August, the village of Totani in September and October, and 

 near Chago in December. Mr. Berezovsky met with this 

 Titmouse only in the mountains of S.W. Kan-su, where it is 

 rare, occurring in small parties of five to ten individuals on 

 the outskirts of the forest in valleys at an altitude of 7000 

 to 9000 feet. In habits it is a typical Poecile, very agile, 

 tame, and trustful. Its note resembles that of P. affinis, 

 but is harsher and more discordant.

 about 3 mm. ; 2>6<5; 1st about half the length of the

Only one specimen was obtained in the gorge of the River 

 Yo-dzam-pu, in the district of Ming-djau, in July. It was 

 in the outskirts of the forest, on the summit of the ridge 

 between two valleys, and was on a dry dead branch, whence 

 it darted into the air in pursuit of insects, like a Flycatcher. 

 This species is very close to Sitta leucopsis, differing, it would 

 seem, only in being smaller and in having almost the entire 

 underparts strongly rufescent.
