THE BIEDS OF MONGOLIA ETC. 195 



102. PiPASTES AGiLis, Sykes. 



Pipastes agilis, Gould^ Birds of Asia^ part xvii, pi. 



This species is very closely allied to P. arboreus, and was found by us 

 during the autumnal migration in Mongolia and Ala-shan. In Kan-su it is 

 tolerably common, and breeds in the wooded valleys of the mountains. Its 

 song is very pleasant. 



In Ussuri country the present species (perhaps P. arhoreus) is very 

 scarce^ occurring only now and then in the fir- woods. 



103. Agrodroma CAMPESTRis, Bcchst. Shevritza polevaya. 



Is extremely common in S.E. Mongolia and the Hoang-ho valley, and is 

 by no means scarce in Ala-shan. It breeds, in company with Larks, amidst 

 thick bushes. The first migrants we noticed arrived in Mongolia on the 

 23rd of April. 



104. CORYDALLA RICHARDII, Vicill. 



It inhabits the same localities as the preceding species, and breeds in 

 limited numbers in Kan-su, in localities where there are plenty of bushes. 

 The first spring migrants were noticed on the 4th of May. When rising in 

 the air its movements are similar to those of A, pratensis. At Urgey and 

 about Lake Hanka it is tolerably abundant from the end of April till the 

 beginning of September ; it breeds in the steppes, avoiding the tall and thick 

 grass of the marshes.
