wooded parts of Muni-ul. In Ordos and Kan-su it has been observed only 

 in limited numbers during migration. 



At Lake Hanka these birds appear about the end of March in only 

 limited numbers, and apparently do not stop there to breed, but rear their 

 young in the more desolate parts of the Ussuri and Amur countries, returning 

 to the south in large flocks vid Hanka.

In the early part of April we met with some migrants at Dalai-nor ; and 

 in July we observed them in the Hoang-ho valley, where the bird probably

 desert, four young birds at a well, which evidently had lost themselves. 



In the Ussuri country we found P. leucorodia, and have brought home one 

 specimen from Lake Hanka. There they are very common from the end of 

 March until the beginning of April, and breed in similar localities at

 young leave their nests towards the end of June or beginning of July, and 

 then commence to wander about on the marshes.

 the Koko-nor and Kan-su mountains, keeping mostly to the brooks and 

 rivulets of the middle circle. Each pair occupies its particular district, where
