APPENDIX. 
The plumage of the female very much resembles that of the female Eider, 
but the two species may be always distinguished by the bill, the gibbous 
part of which is arched on the top in the King, and flattened in the Eider. 
The bill of the latter is also longer, and the feathers on the side of the upper 
mandible extend as low down as they do on the lower mandible, which is 
not the case in the King Duck. The colours of the plumage of the head and 
neck of the Eider nearly correspond with those of the body, whereas in the 
King they are much lighter. Some of the female Kings which were killed 
had the whole of their under parts an uniform dark brown, whilst others had 
more or less of dark markings on a lighter ground. The hind toes in both 
sexes are smaller than those of the Eider. 
A young male was killed, towards the end of September, which bore the 
same resemblance to the female as the young male Eider does to the female 
of its own species.

Is abundant on the shores of Davis’ Strait and Baffin’s Bay ; but, deriving 
its food principally from the sea, was not met with after the entrance of the 
ships into the Polar Ocean, where so little open water is found. The females 
were without the white bands on the wings, which are described by authors.

Breeds in the North Georgian Islands, but is not common there. A male 
bird was obtained in June, corresponding precisely with the individual killed 
in Baffin’s Bay in the summer of 1818, which furnished the description of the 
full-breeding plumage in the Mefnoir oj^ the Greenland Birds. An account of 
this state of plumage is yet wanting to complete the history of this species 
in Mr. Temminck’s second edition. The plumage of a young male, killed
