2 Mr. A. G. More on the Distribution of Birds 
the geographical distribution of British plants, the ‘Cybele 
Britannica.’ 
The present outline is confessedly imperfect, not only from the 
insufficient number of observers, but because it has been thought 
better in many cases to withhold information of a doubtful 
character, rather than run the risk of mixing good with bad 
authority ; and as no pains have been spared to investigate every 
disputed point, it is hoped that the results may be accepted as 
tolerably accurate so far as they go. 
Had our scheme any claim to completeness, it might no doubt 
be considered partly as a record of the present and past distribu- 
tion of several species now fast decreasing through the progress 
of cultivation and drainage, and, we regret to add, the persecu- 
tion of game-preservers and collectors. It might also become a 
measure of the future increase of other birds which seem to 
flourish under the protecting hand of man. 
The present results might also be used as a means of ascer- 
taining some particulars of the movements of birds which remain 
in Britain all the year, and yet are partially migratory. This 
might be accomplished by noting the districts which a bird fre- 
quents during summer or winter only, or in which any species 
is more numerous at one season than another. 
it is hoped that all who may feel interested in the subject of 
this paper will not fail to point out any imaccuracy which they 
may observe, and that they will also endeavour to supply the 
omissions unavoidable in a first attempt. It is suggested that 
such additions might form an interesting subject for communi- 
cation to the ‘Ibis,’ even if only one additional district can be 
filled up on good authority. Full lists of the nesting-birds of 
South and North Wales, of the North-west of England, and of 
almost any part of Scotland are especially desired. 
In acknowledging how much is due to the kind cooperation 
of the many friends and correspondents who have assisted in this 
undertaking, I have especially to thank Dr. J. A. Smith of 
Edinburgh, the Rev. George Gordon of Birnie, and Mr. Robert 
Gray, Secretary to the Natural History Society of Glasgow, who 
have not only furnished me with information themselves, but 
have taken great pains in collecting lists from various parts of 
Scotland.
