No. 3, with this remarkable difference, that the webs are not more 
than one-fourth of an inch wide, each of them, and are moreover of 
equal breadth throughout the whole length of the feathers—I mean, 
of course, of the two central long feathers. It is remarkable that 
there is not a very great difference in length between the skua and the 
Buffonii, for what each of the species (including Nos. 2 and 3) want 
in bulk of body is made up by the greater elongation of the two tail- 
feathers when the birds are adult. It is also remarkable that the skua 
has never been known to assume any portion of the light colour so 
conspicuous after the second year in pomerinus, Richardsonii and 
Buffonii. A skua that lived ten years in confinement remained 
during the whole time of the same uniform brown colour. If 
I should not have met all your wishes about the species of Lestris 
let me hear from you again.

The Ornithology of Shakespeare critically Examined, Explained 
and Illustrated. By James Epmunpo Hartine, F.LS., 
F.Z.S., &c. London: Van Voorst. 1871. 
Reavers of the ‘ Zoologist’ may remember a very interesting 
series of papers on the ‘ Ornithology of Shakespeare’ which were 
contributed to it in the volumes for 1866 and 1867, by Mr. J. E. 
Harting. The work which we have now the pleasure of noticing 
is not merely a reprint of these, but contains so much additional 
matter that it numbers (as Mr. Harting states in his preface) 300 
pages, against the 80 which appeared originally in the ‘ Zoologist.’ 
And besides this large increase of matter, all that had been pre- 
viously written has been carefully re-arranged and blended with 
the new material, which has been collected by patient research. 
The result is a book which is interesting not only to the ornitholo- 
gist but also to the general reader, and which is moreover extremely 
attractive from the numerous head-pieces and vignettes with which 
it is illustrated: the drawings for these have been furnished by the 
pencil of Mr. J.G. Keulemans. We may mention a head-piece at
