292 THE WHITE-FACED STIFF-TAIL DUCK. 
“ Adult Female (Zah, 16th May )—Differs from the male in 
lacking the clear white on the head, and in being much more 
rufous in plumage; crown and nape blackish brown, with a 
chestnut tinge; sides of the head similarly coloured, but marked 
with white ; a white streak passes below the eye nearly to the 
nape ; and the chin and upper throat are white, slightly dotted 
with blackish brown ; general colour of the upper parts darker 
than in the male, being deep chestnut-red ; underparts as in 
the male; bill dull plumbeous ; iris dark brown; legs plum- 
beous black. , 
“ Voung (vide Hf. Otto, ‘lbts; 1875, p. 428)—Beak bluish 
black, with a swelling at the base; feet of a similar colour ; 
plumage brown-black; from the base of the bill, under the 
eye, and continued over the ear, a white stripe ; chin, witha 
broad outward curve back under the cheek, white, so that the 
brown cheek appears bordered underneath by this curve, and 
above by the eye-stripe ; belly dirty white, which colour loses 
itself in the sides; under the shoulder a light spot on both 
sides, which hardly shines through, and in many specimens 
is wanting ; tail-feathers slit up and spread out like a fan.”
