THE BUFFEL-IIEADS. GENUS CHARITONETTA.

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

being exactly the opposite to the features of the nostril in the 
genus Clattgula. In my opinion, therefore, the genus Charito- 
netta should be recognised.
