the Russian Empire to the great Yenesei River (Seebohm 
aud Popham). It reaches China (Ibis, 1892, p. 490) and 
Japan, and has been recently obtained in Burma by Col. 
Rippon. Mr. Blanford writes of it as ^' a very rare cold- 
weather immigrant in Northern India/' and examples have 
been lately procured at Calcutta (cf. Finn, P. A. S. Beng. 
1898, p. 1). It has been repeatedly shot in Greece, where 
it is said even to breed. It not infrequently comes as near 
to us as Denmark and Holland (see Zoologist, 1885, p. 33), 
and M.Dubois cites two occurrences in Belgium (November 
1856 and winter of 1858), while Mr. Howard Saunders 
examined one in Italy (Ibis, 1869, p. 395). As might be 
expected, it is occasionally obtained in Northern Egypt in 
winter (see P. Z. S. 1876, p. 414). The accompanying map 
(fig. 8) will best shew its distribution.

There are some naturalists who would unite the three 
White-fronted Geese under one name, but this seems an 
unscientific way of treating the question, and so long as 
the slightest difference in colour — even to the colour of an 
eyelid — can be found, combined (as it is in their case) with
