elevation, and, like the Golden-Eye, producing a loud 
whistling sound by the action of its wings——It obtains its 
food principally by diving, searching the bottoms of the 
streams for the larvee of insects, the roe of fish, and testace- 
ous mollusca. Its nest is said to be made upon the banks 
of rivulets, under the cover of low bushes or tall herbage, 
and its eggs, from ten to twelve in number, are stated to be 
of a pure white, and not much larger than those of a pigeon. 
During its summer migration it is found upon the coast, and 
frequently in deep water, at a considerable distance from 
land. It is to be regretted, that no author has described the 
anatomy of the trachea, as it so essentially contributes to es- 
tablish the affinities of the species. In the form of the bill 
a slight difference is observable, as compared with that of the 
Golden-Eye, and the nostrils are placed nearer to the base, 
shewing its connexion with the genus Havelda.
