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. Grurney will give us the benefit of his 

 views upon the entire subject, which is a somewhat wide one. 

 Severtzoff's ' Ornithologie de Turkestan ' will, we are told, 

 form a separate volume. 



46. ' The Naturalist: 



[' TLe Naturalist : ' a Journal of Natural History for the Nortli 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 commvinications 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 Tcesdale; 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 [HydrocJielidon 

 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 clanga. Many of the minor 

 notes are interesting, and ' The Naturalist ' shows no signs 

 of flagging.
