LONG-TAILED DUCK. 
[Plate LXX. — Fig 2, Female.'] 
Jnas hyemalis, Linn. Syst. 202. 29. — Lath. Syn. iii, p. 529.*

The female is distinguished from the male by wanting the 
lengthened tertials, and the two long pointed feathers of the 
tail, and also by her size, and the rest of her plumage, which 
is as follows: length sixteen inches, extent twenty-eight inches; 
bill dusky; middle of the crown and spot on the side of the 
neck blackish; a narrow dusky line runs along the throat for 
two inches; rest of the head and upper half of the neck white, 
lower half pale vinaceous bay blended with white; all the rest 
of the lower parts of the body pure white; back, scapulars, and 
lesser wing coverts bright ferruginous, centred with black, and 
intei’spersed with whitish; shoulders of the wing, and quills 
black; lower part of the back the same, tinged with brown; 
tail pale brown ash, inner vanes of all but the two middle fea- 
thers white; legs and feet dusky slate. The legs are placed far 
behind, which circumstance points out the species to be great 
divers. In some females the upper parts are less ferruginous. 
Some writers suppose the singular voice, or call, of this spe- 
cies, to be occasioned by the remarkable construction of its 
windpipe; but the fact, that the females are uniformly the most 
noisy, and yet are entirely destitute of the singularities of this 
conformation, overthrows the probability of this supposition.
