STELLER’S WESTERN DUCK. 43 
the eye is a narrow circle of biack, inclining also forwards 
and backwards, forming a spot on the back of the head. 
Head on the sides, crown, and the neck on the upper part, 
white, forming a collar which is only infringed on by the 
blackish brown of the chin. There is another pale green spot 
at the back of the head. The nape below tke white is 
black, and this colour also comes round the neck. Chim and 
throat, rich blackish brown; breast above, white, on the middle 
and lower part rich chesnut brown, darker on the latter, 
passing into buff in front and on the sides just below the 
point of the wing. Back, all along the middle part, black; 
there is a black patch formed by the tips of the otherwise 
white feathers. 
Just above the joint of the wing is a black spot with 
green reflections; lesser wing coverts, white; primaries, dusky 
blackish brown; secondaries, partly white, the outer web 
metallic blue, forming the speculum-—the end portion white. 
The tertiaries are long and pointed, white on the inner webs, | 
rich blue on the outer, and curved downwards, as are the 
long scapulars, which are also marked like the four upper 
tertiaries, namely, the narrow inner webs white, and the broader 
outer ones rich blackish metallic blue, and the shaft streak 
white. Tail, dusky blackish brown, and rather more pointed 
than in others of this genus; upper tail coverts, black, with 
a tint of blue; under tail coverts, dark brownish black. Leys 
and toes, olive green—the hind toe has a deep lobe; webs, 
olive green. 
The female has the bill olive black, the tooth yellow horn- 
colour; greater wing coverts, dusky olive brown, tipped with 
white; lesser wing coverts, dusky olive brown; primaries, dusky; 
the secondaries also tipped with white, thus forming two bars 
across the wing, between which is the speculum of rich chesnut 
colour. Of the tertiaries the three longest are dusky. Tail, 
dusky. Legs and toes, pale bluish; claws, black; webs, blackish.
