" The present species is a quick and lively bird, which very seldom sits 

 quietly, but usually flies from one branch to another. About the middle 

 of May the small flocks had not yet paired. 



" The Kan-su mountains form the northern boundary of distribution for 

 the present species." 



The nest and eggs have not yet been discovered. 



The details of the male, female, and young male, are taken from 

 examples procured by Colonel Prjevalski, at Kan-su in N. W. China, and 

 are now in the collection of Mr. H. Seebohm, who courteously sent these 

 beautiful skins to me for examination.
