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 character of the avifauna is distinctly Himalayan, but 
many migrants from the north pass the winter in Yunnan. 
Schiller on Danish Birds.

An example of the rare Goose Anser neglectus killed at 
Ballum, on the west coast of Schleswig, has recently been 
acquired bv Mr. Schipler, 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. Schipler 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.
