ANATIDJ!— THE SWANS, GEESE, AND DUCKS. 191 



The genus Lophodytes is quite distinct from Merganser in the 

 possession of the above characters. The bill is also much more 

 depressed terminally, and, in proportion to its leng;th, deeper 

 through the base. The nostrils are situated far back, as in 

 M. serrator. But one species is known, unless the Mergus octo- 

 setaceus of Vieillot, a South American bird, which we have not 

 seen, be referable to this gemis rather than to Mergus.
