captivity * (Zool. 1888, p. 176). A third example had been 
previously seen (about 1874) by the late Mr. J. Cordeaux in 
a game-shop at Grimsby (B. Humber District, p. 22). 
In October 1871 an immature White-fronted Goose, with 
a very short beak, was bought in Leader hall Market, which 
puzzled my father and me, but which I now think was 
A. erythropus ; whether it was British-killed or not it is 
impossible to say. This was a young bird and the general 
tone of its plumage was distinctly dark, a feature noticed by 
the late Mr. Seebohm (P. Z. S. 1886, p, 420), but which I am 
afraid is not constant. It had no bars on the breast or 
belly, a fact which in all the White-fronted Geese has been 
regarded as a mark of immaturity, but I have known an 
example of A. albifrons to live about four years on a pond at 
Cromer without acquiring bars. 
XVIII. — Further Notes on the Birds of the Outer Hebrides. 
By J. A. Harvie-Brown, F.R.S.E. 
Many striking changes in the Avifauna of the Outer Hebrides 
have been brought to the notice of ornithologists since I 
visited the group along with Colonel Feilden in the year 
1870, though whether some of these changes are not more 
apparent than real is a point which cannot at present be 
regarded with absolute certainty. Personally, however, I am 
of opinion that most of the new records are due to an extension 
of range of the species, whether on migration or otherwise, 
while it is an undoubted fact that certain birds are incom- 
parably more plentiful than they were even in 1888, when 
the ^ Fauna of the Outer Hebrides' issued from the press. 
To these changes then I particularly desire to draw attention 
in this paper, now that a large mass of fresh information has 
been collected by personal investigations and by the aid of 
many kind correspondents; and I hope to publish in an 
early part of the ' Annals of Scottish Natural History ' full 
details regarding the species concerned. 
* Four or five examples of this Goose have lived in the Gardens of the 
Zoological Society of London at different times.
