THE BIEDS OF MONGOLIA ETC. 



often met them in the mountain-meadows about the end of August. The 

 different famiUes assemble in large flocks of one or two hundred, and about 

 the middle of September leave for the south, to arrive again in spring about 

 the middle of April.

We only once observed a flock of this species in Ala-shan. It was during 

 the autumnal migration, in the month of September ; and another time we 

 met with it near Lake Hanka, during the spring migration, which takes place 

 in April and May ; and at that time it was common in the bushes and grass 

 of the Tungatchin steppes.

Is very closely allied to the preceding species, but differs from it con- 

 stantly (a) by the want of the black spots on the breast ; and although there 

 are now and then some other blackish stripes on the flank, they are hardly 

 perceivable ; (6) the present species has a whitish throat and pure white 

 eyebrows ; (c) the upper parts of the body are greyish, and not rusty 

 brown, like A. montanellus. 



The comparative measurements are the following : —
