ANAS ALBOGU LARIS 
it for the sake of completeness. This tendency to irregular white areas about the head was noticed 
by Finn (1907). It is probably analogous to the partial albinism found in the Laysan Teal, and due 
to close inbreeding in places where the species has been killed down to small numbers. Specimens in 
the British Museum from Port Blair and from Dungleaf Creek show a considenable amount of 
albinism, especially in a large, irregular patch at the base of the culmen and around the eye. A single 
bird which I saw at the London Gardens in 1922 was entirely white-headed and Mr. Seth-Smith told 
me that their stock became progressively whiter the more it was inbred.
