TUFTED DUCK. - Cuass U1. 
coverts of the wings are of a pure white; the 
quil feathers dusky on their exterior sides and 
ends, part of their interior webs are white; the 
secondaries white tipt with black; the rest of 
the plumage is black, varied about the head 
with purple; the tail is very short, and consists 
of fourteen feathers; the legs are of a bluish 
grey, the webs black. The female wants the 
crest. 
When young, this sex is of a deep brown, 
and the sides of the head next the bill are of a 
pale yellow ; but it preserves the other marks 
of the old duck. In this state it has been de- 
scribed in the Ornith. boreal. 91, under the title 
of Anas latirostra.
