90 THE BIRDS OF MONGOLIA ETC. 



240. Tringa temminckic, Leisl. Pesochnic Temmincka. 



During the spring migration, which commences about the middle of 

 April, this species is tolerably common in S.E. MongoUa; and in the 

 summer, in July, we met with it in the Hoang-ho valley, where it probably 

 breeds. In Gobi a few migrating individuals were observed during the month 

 of August ; they kept mostly to the small rain-pools. It does not occur in 

 Kan-su ; nor did we find it at Koko-nor ; but its absence in the latter place 

 might be accounted for by our being there only late in autumn and early in 

 spring. 



241. Trtnga subminuta, Midd. 



T. subminuta inhabits the whole of S.E. Mongolia, with the exception of 

 the Ala-shan. We did not observe it at all in Kan-su and about Koko-nor. 



242. Tringa subarcuata, L. Pesochnic crivonosoy. 



A few^ birds were obtained in the Hoang-ho valley in summer ; it most 

 likely breeds there. 



In the Ussuri country, one was seen by me near Lake Hanka. 



243. Gallinago scolopacina, Bp, Becas barashec. 



Is rather a rare breeding bird in the Hoang-ho valley, and probably also 

 in S.E. Mongolia, where great numbers were seen on migration. This 

 commences very late, namely about the 10th of April, and lasts until the 

 beginning or middle of May. 



On account of the scarcity of marshes, G. scolopacina inhabits the shores 

 of lakes. When there are morning frosts (which last until the end of 

 April, and occasionally even until the beginning of May), the shores of
