I4O BRITISH BIRDS, 



some bluish-grey, of a darker tint, however, than in 

 A. cinereus. It is still smaller than A. segetum, length 

 of male being 28*00 to 29-00 ; female slightly smaller. 

 A regular winter visitor to the east coast, but rarer in 

 the west or south. In Ireland, where the last species 

 is of regular occurrence, the present form has only once 

 been obtained, /.*., an example shot on Lough S willy in 

 October, 1891 (Zool., 1892, p. 33). 



206. Anser albifrons (Scop.). WHITE-FRONTED 

 GOOSE. 



Hab. Northern Palaearctic region (except Scandinavia), 

 breeding chiefly within the Arctic Circle. In winter 

 migrating southward. 



Closely related to the three preceding species, but 

 adult is at once distinguished by its having the feathers 

 on forehead and around base of upper mandible white ; 

 breast and sides are broadly banded with black and bill 

 is orange, but with a white nail ; feet are also orange. 

 Length from 26*00 to 28*00, female being slightly smaller 

 than male. A regular winter visitor, but apparently 

 most common on the west side. It is the commonest 

 of the " Grey Geese " which visit Ireland. 



206a. A. albifrons erythropus (Linn.). LESSER 

 WHITE-FRONTED GOOSE. 



Hab. Arctic Norway. In winter migrating southward. 



A smaller race than the last ; distinguished chiefly by 

 having the white on forehead extending fully as far 

 behind as the level of the eye ; bill also is shorter, and 

 ridge above is straight, forming a line with the forehead. 

 A genuine example was shot by Mr. A. C. Chapman at 

 Holy Island, Northumberland, September i6th, 1886.
