WILD FOWL 
Nest and eggs. — ^The nest is similar to that of the bean-goose. Three 
eggs taken by Mr A. Trevor-Battye in Spitzbergen on the 26th of June 
were slightly incubated. They are yellowish -white, and the average 
measurements are 3*3 by 2 15 inches. Another clutch of five eggs was 
taken by H. Stjernspetz on Spitzbergen on the 15th of June. 
The weight of adult birds varies from 5| to 7 lbs. 
Allied form. — In Kolguev and Novaya Zemlia, a larger form known as 
Sushkin’s goose {Anser neglectus) replaces the pink -footed goose as a breed- 
ing species. It winters in Eastern Europe, being common on migration 
in the Ufa Government of East Russia: it is also met with in Persia, and 
appears to be almost certainly the form which has been met with in India.

General distribution. — ^The snow-goose probably nests in the Arctic 
regions of Eastern Asia from the Lena eastwards, and in Western 
North America from the Mackenzie River east to Melville Island. In 
winter it migrates southwards to Japan, while some small proportion 
move westwards and have been observed from time to time in many 
parts of North-western Europe and southwards in Greece and the Caspian, 
which is said to be visited regularly in winter. In North America it visits 
the whole of the western parts between the Pacific Ocean and the Valley
