Tuts recently discovered species, in size about one-third 
less than the Whistling Swan, is also amongst the number of 
_._ our British winter visitants ; and though less numerous as a 
ee species than the other, is occasionally met with in England 
during every severe winter. The merit of the first discovery 
of the present species is due to Mr Ricnarp WineatsE of 
Newcastle-upon-Tyne, who, in consequence of the observa- 
tions he had made upon two specimens of Wild Swans killed 
in the neighbourhood, in the winter of 1828-9, read a paper 
before the Literary and Philosophical Society of that town, 
stating the peculiarities he had noticed in these birds, as well 
in outward form, as in internal structure, and also his opi- 
nion that the differences exhibited were of sufficient import- 
ance to entitle them to rank as a distinct species, both from 
the preceding one and also from the tame Swan (Cygnus 
Olor ). These remarks induced other naturalists to investi- 
gate the subject, and Mr YarRrett, whose knowledge as an 
ornithologist, and whose discrimination as a comparative 
anatomist, stand deservedly high, soon discovered additional 
proofs of the correctness of Mr Winearte’s views, and, at 
his suggestion, the appellation of Cygnus Bewickii was con- 
ferred upon the species. Since that period, several speci- 
mens of the bird have been obtained, and its distinguishing 
characters have been illustrated and fully described by Mr
