306 ANATID^E. 



kindness of Mr. Charles Buckler, who allowed me the use 

 of a drawing taken by himself from the bird at Norwich, I 

 am enabled to give an exact representation of the only British 

 killed specimen that I am acquainted with. It is a male 

 very closely approaching the perfect plumage of an adult. 



This species of Duck has now been killed three or four 

 times in Sweden, and once in Denmark. Professor Nils- 

 son, in his Fauna of Scandinavia, has given coloured 

 figures of both sexes; and M. Temminck further remarks 

 that it visits the Eastern parts of the North of Europe, 

 and has occasionally wandered into Germany. 



It inhabits Asia and North America ; was originally de- 

 scribed, from specimens obtained by Steller, in Kamt- 

 schatka, where it breeds upon rocks inaccessible to man. 

 Dr. Latham mentions that there was a specimen formerly 

 in the Leverian Museum. Examples have been brought 

 from the Western side of North America, and it was in 

 consequence called the Western Duck, and Anas occidua. 

 The description of the plumage of the adult male here 

 given was taken from a beautiful specimen in the possession 

 of Mr. John Leadbeater. 



It is stated of this species that it flies in flocks, and 

 never enters the mouths of rivers. Its food is marine 

 insects, with mollusca naked and testaceous. 



It will be observed that some of the English authors 

 quoted under the figure of the bird, have considered it a 

 Fuligula, and have arranged it among the Pochards, not, 

 however, without some doubts that this would probably 

 be found not to be its natural situation. The anatomy, 

 which I believe is as yet unknown, will at some future time 

 indicate the proper location ; but in its general character 

 and appearance, with its habit of breeding on high and 

 steep rocks, it appears to me to be more closely allied to
