half to the Tring Museum. Twenty new species and sub- 

 species are described, but some of these are from other 

 parts of the Indian Region and do not form part of the 

 Forrest collection. 



The number of forms now known from Yunnan amounts 

 to 496, out of which 59 are added in the present paper. 

 The ciiaracter of the avifauna is distinctly Himalayan, but 

 many migrants from the north pass the winter in Yunnan. 



Schi0ler on Danish Birds.

An example of the rare Goose Anser neglectus killed at 

 Ballum, on the west coast of Schleswig, has recently been 

 acquired by Mr. Schi0ler, who has a wonderful collection of 

 Palsearctic Water-birds. It is the first record for Denmark. 

 Mr. Schipler in this paper discusses its status and affinities 

 but comes to no very definite conclusions, and until its 

 breeding-place, said to be Nova Zembla, is accurately known 

 it will be difficult to do so. 



The Upland Plover (^Bartramia longicauda) is a well-known 

 North-American bird, and has occasionally reached the 

 British Islands and the continent of Europe. An immature 

 female example was found by Mr. Schioier among some 

 Snipe in the Copenhagen market. These had been killed 

 at Tim in western Jutland. It is the first record of the 

 occurrence of the Upland Plover in Denmark.
