452 Mr. YARRELL on a new Species of Wild Swan. 
Ornithological Dictionary, it appears Mr. Montagu considered 
the structure of the trachea in the new species, which he has 
accurately described, as the sexual distinction of the male 
Hooper, and the figure in Dr. Latham’s paper, as representing 
the form common to the female; but this assuredly is not the 
case. Dr. Latham, M. Temminck, and others who have de- 
scribed the tracheal structure of the Hooper, have stated it as 
common to both sexes of that bird, and my own multiplied 
observations confirm the fact. I have examined males and fe- 
males of both species. 
Several examples of this new species are now ascertained to 
be in British collections. The Museum of the Cambridge Phi- 
losophical Society contains one. There is one in the possession 
of Edward Lombe, Esq. of Great Melton, who has an excellent 
collection of British birds. A third was shot in the winter of 
1827-28 by Colonel Hawker. These three were preserved by 
Mr. Leadbeater. A specimen was also killed in February 1829 
near Haydon Bridge, upon which bird some remarks have been 
lately made before the Natural History Society of Newcastle, 
by Mr. Richard Wingate of that town. I have also had the 
pleasure of presenting three specimens, which furnished part of 
the materials for this paper, to the collections of the British 
Museum and the Linnean and Zoological Societies. 
It is my intention, and on this occasion I anticipate the ac- 
cordance of every British naturalist, to devote this species, 
which, I trust, I have proved to be distinct and unnamed before, 
to the memory of our late unrivalled engraver on wood, the 
justly celebrated Bewick. The instruction and gratification 
which thousands have derived from the beautiful and animated 
delineations of this most faithful illustrator of Nature, in all her 
varied scenes and objects, entitle him to this tribute; and I 
rejoice in the opportunity this new species affords me of attach-
