450 Recently published Ornithological Works. 
The notes do not seem to include any thing of novelty, the 
most remarkable facts mentioned (the breeding of Tringa 
cinclus and Mareca penelope in the district) having been 
before recorded on the author’s authority in our pages (Ibis, 
1865, pp. 438, 444). 
On the completion of each of his great works, Mr. Gould 
has published the f Introductions’ in an octavo volume. This 
plan has been of great assistance to working ornithologists 
making references to such large books. The volume* now 
before us contains the introductory matter accompanying 
‘ The Birds of Great Britain/ on the completion of which 
we have recently had occasion to congratulate Mr. Gould. 
Since our last notice of Mr. Dresser’s f Birds of Europe’ f, 
four more numbers have been issued. 
A number of Sylviidse are figured and treated of in these 
parts, including some Saxicolinse, an intricate group which 
Mr. Dresser and Mr. Blanford have carefully worked out in 
a recently published part of the Zoological Society’s c Pro¬ 
ceedings 9 (1874, p. 213 et seqq.) . Progress is also made with 
the genus Lag opus; and interesting notes, illustrated by a 
plate, are given of the shedding and growth of the claws and 
the assumption of the feathers on the toes at certain seasons 
by Lagopus albus. The Corvidae, Certhiidse, Glareolidse, 
Cuculidse, Hirundinidse, Accipitres, Sturnidse, Cypselidse, 
Anatidse, Laridse, and Procellariidse, all come in for a share of 
attention. In the double number the profuse synonymy of 
that unfortunate bird, the Yellow-browed Warbler of Latham, 
Phylloscopus superciliosus (Gmelin) is very fully worked out 
by Lord Walden. The extent to which this poor bird has 
been misnamed can be realized by glancing at its list of 
synonyms, which occupy nearly two quarto pages of Mr. 
Dresser’s work! 
As we have frequently spoken in terms of praise of this 
admirable work, suffice it to say that the present numbers
