Breeds in the arctic regions, but regularly migrates southwards during winter ; is found commonly 

 in Europe, frequenting both fresh and sea water, but more commonly the latter ; during the breed- 

 ing season, however, they are stated by travellers to frequent exclusively fresh water, making their 

 nest on the shores of lakes and rivers in the fur countries, and laying from seven to ten white eggs. 

 The trachea has a large contractile bulb on the tube ; the inferior larynx is not very dissimilar 

 from that of the Mergansers ,• the tube is acted upon by two pairs of muscles of voice, the first of 

 which are the usual sterno-tracheab ones, the second pair (which are furculo-tracheal) diverge from 

 the tube at a little distance below the contractile bulb,, and have their insertion on the rami of the 

 os furcatum near the middle of eacb.

It is even now doubtful whether or not many of the birds of Nortb America are distinct from 

 (.in own. There is, however, between many of them found enough of distinction for the practised 

 eye of an ornithologist to say with certainty, this bird is North American — this European.
