falco, but generally paler in colour. As an immature ex¬ 
ample was formerly figured, it is a pity that we have not now 
in addition the representation of an adult. As regards the 
second paper, it is only the commencement of a treatise 
which will not be finished until this year. After that, per¬ 
haps, Mr. J. H. Gurney will give us the benefit of his 
views upon the entire subject, which is a somewhat wide one.

[‘The Naturalist:’ a Journal of Natural History for the North of 
England. Edited by W. D. Roebuck and W. E. Clarke. Nos. 116-128.] 
We are glad to see, in Nos. 117 and 118, the continuation 
and conclusion of the useful bibliography of papers for 1884, 
relating to the Birds of the North of England, to which we 
have already drawn attention (Ibis, 1885, p. 230), while 
interesting communications from various well-known orni¬ 
thologists are not wanting. Messrs. Clarke and Cordeaux 
keep us informed as to the arrivals and migrations on the 
east coast; Mr. J. Backhouse, jun., sends notes on the Birds 
of Upper Teesdale; Mr. Alfred C. Chapman contributes 
some interesting experiences of the Northumberland coast 
birds; and Mr. Armistead treats of those of the Solway 
district. Mr. Southwell states that a previously unre¬ 
corded specimen of the Whiskered Tern ( Hgdrochelidon 
hybrida) , formerly in the collection of the late Mr. Rising, 
of Horsey, near Yarmouth, was obtained in 1842 at Hornby 
Castle, on the Swale, in Yorkshire, probably the most 
northern occurrence of this species. A note by Mr. Archer, 
on a Spotted Eagle killed on 31st October last, in Nor¬ 
thumberland, is followed by an article by Mr. J. H. Gurney, 
on the two races or subspecies of Spotted Eagle found in 
Europe, the Northumberland example being referred to the 
larger form, known as Aquila clang a. Many of the minor 
notes are interesting, and f The Naturalist 3 shows no signs 
of flagging.
