It is not improbable, as Mr. Yarrell .suggests, that this species and C. Buccinator will be 

 found to be confined to America ; C. Beivickii and C. ferns representing them in Europe. 



Dr. Richardson, in the " Fauna Boreali Americana," says that " this swan breeds on the sea 

 coast within the arctic circle, and is seen in the fur countries on its passage only. It makes its 

 appearance among the latest of the migratory birds in the spring, while the Trumpeter swans air, 

 with the exception of the eagles, the earliest. Capt. Lyon describes its nest as built of moss peat, 

 nearly six feet long, four feet and three cpiarters wide, and two feet high exteriorly ; the cavity a 

 foot and half in diameter, the eggs brownish white slightly coloured with darker tints."

Dr. Richardson informs us, in the "Fauna Boreali Americana," that "this is the most common 

 of the genus in the interior of the fur countries. It breeds as far south as lat. 61, but principally 

 within the arctic circle, and in its migrations generally precedes the geese a few days. A fold of its 

 trachea enters a protuberance on the dorsal or interior aspect of the sternum at its upper part, which 

 is wanting in C. ferns and C. Bewickii." It is to the Trumpeter that the bulk of the swan skins 

 imported from Hudson's Bay belong.
