It is not improbable, as Mr. Yarrell suggests, that this species 
and C. Buecinator will be found to be confined to America; 
 C. Bewickii and C. ferus 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 are, with the exception of the eagles, the earliest. — 
Captain Lyon describes its nest as built of moss peat, nearly six feet 
long, four feet and three quarters 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. ferus and C. Bewickii.” It is to the Trumpeter that 
the bulk of the swan skins imported from Hudson’s Bay belong.
