THE BUFFEL-HEADS. GENUS CIIARITONETTA. 



Charitonetta, Stejn. Bull. U.S. Nat. Mus. No. 29, p. 183 (1863). 



Type, C. albeola (Linn.). 



Count Salvador! does not separate the Buffel-heads from the 

 Golden-eyes, though he admits the difference in the style of 

 their plumage, and the structural character of the nostrils, 

 which are situated nearer to the base of the bill than to its tip, 

 being exactly the opposite to the features of the nostril in the 

 genus Clangula. In my opinion, therefore, the genus Chart to- 

 netta should be recognised.
