Oil new Species of Ceydral- Asian Birds. 409 



under tail-featliers, bright yellow. Upper part of the body- 

 yellow or greenish olive; only the front upper tail -coverts 

 show a dark-brown colour. Primaries dark brown, with 

 yellowish margins, wide on the hindermost. The yel- 

 lowish-white tips of the large and median wing-coverts form 

 here two bars. The lower wing-coverts are yellowish white. 

 Rectrices darker than the quills ; in fact almost black, except 

 the two outermost pairs, which are white, with a black edge, 

 extending from the base to two thirds of the inner web, and 

 with a narrow black stripe in the basal half of the secon- 

 daries ; a white speck on the point of the third rectrix. A 

 younger male had hardly any spot here and more black on 

 the white rectrices. 



This Wagtail was first discovered by us in the spring of 

 1879 migrating in Dzungaria, on the Urungu river, and in 

 the Southern Altai. The first arrivals were observed on the 

 15/27 April, but they may have appeared a few days earlier. 

 They kept in small flocks, from five to ten individuals in 

 each, and were frequently seen. In May they ceased to 

 appear, neither did we find them in any other regions visited 

 by us. 



There is, however, an entry in my diary to the effect that 

 on the 31st August (12th September) of the above year, 1879, 

 this species was observed apparently in autumnal flight, on 

 lake Toso-nor in Tsaidam.
