GLAUCIONETTA 291 



Genus GLAUCIONETTA. 



The genus Glaucionetta is a very small one, containing only three 

 species of birds which range throughout the Northern Hemisphere. 

 Of these three, only one, Glaucionetta dangida, reaches India, and 

 even this only occurs with extreme rarity. The most noticeable 

 thing in this genus, and one which at once separates it from all its 

 closest allies, is the position of the nostrils, which are rather nearer 

 the tip than the base of the bill, the position being well shown in 

 the woodcut in Blanford's fourth volume of the ' Fauna of British 

 India.' In many respects in its anatomy it closely approaches the 

 Mergansers, and it is a sort of link between them and the more 

 typical ducks. 



As the generic term Clangula cannot be used, the correct name 

 appears to be Stegneger's name Glaucionetta, and not Bucephalus.
