On Oygnus Passmori, a supposed new American Swan. 

 By the Eev. W. Hincks, F.L.S., Prof. Nat. Hist. IJniv. of Toronto. 



[Eead January 21, 1864.] 



Mr. Passmore, taxidermist, of Toronto, who is an experienced 

 and intelligent observer of the objects which his occupation brings 

 under his notice, obtained a Swan diu-ing the last winter, which 

 appeared to him so remarkable that he called my attention to it, 

 and requested my opinion as to the species to which it belongs. 

 On examining it with care, I came to the conclusion that it has 

 not yet been described ; and although the comparison of further 

 specimens would be very desirable, I venture to lay the observa- 

 tions I have made before the Linnean Society, and to name the 

 new species, from its discoverer, Oygnus Passmori. 



I regret that I did not see the bird until after it had been pre- 

 pared, when it was no longer possible to obtain all the measure- 

 ments which I should wish to give ; but as the sternum, with the 

 trachea, was placed in my hands, and I had also two specimens of 

 the same parts taken from the Oygnus huccinator, I find myself 

 able to give abundantly sufl&cient characters, accompanied by an 

 interesting correction of the labours of my predecessors. 



The Swan which I now introduce to the notice of naturalists 

 resembles in its general aspect Oygnus buccinator of Kichardson,
