‘ 
FEMALE LONG-TAILED DUCK. 597 
with the down of her breast, which is accounted equally valuable with 
that of the Eider Duck, were-it to be had in the same quantity.* They 
are hardy birds, and excellent: divers. Are not very common in Eng- 
Jand, coming there only in very severe winters; and then but in small, 
straggling parties ; yet are found on the coast of America, as far south 
at least as Charleston, in Carolina, during the winter.’ Their ‘flesh is 
held in no great estimation, having a fishy taste. The down and plu- 
mage, particularly on the breast and lower parts of the body, are very 
abundant, and appear to be of the best quality. 
The length of this species is twenty-two inches; extent, thirty 
inches; bill, black, crossed near the extremity by a band of orange; 
tongue, downy ; iris, dark red; cheeks and frontlet, dull dusky drab, 
passing over the eye, and joining a large patch of black on the side 
of the neck, which ends in dark brown; throat and rest of the neck, 
white; crown, tufted, and of a pale cream color; lower part of the 
neck, breast, back, and wings, black ; scapulars and tertials, pale blu- 
ish white, long, and pointed, and falling gracefully over the wings; 
the white of the lower part of the neck spreads over the back an inch 
or two; the white of the belly spreads over the sides, and nearly 
meets at the rump; secondaries, chestnut, forming a bar across the 
wing; primaries, rump, and tail-coverts, black; the tail consists of 
fourteen feathers, all remarkably pointed, the two middle ones nearly 
four inches longer than the others; these, with the two adjoining ones, 
are black; the rest, white; legs and feet, dusky slate. 
On dissection, the intestines were found to measute five feet six 
inches. The windpipe was very curiously formed; besides the 
labyrinth, which is nearly as large as the end of the thumb, it has an 
expansion, immediately above that, of double its usual diameter, which 
continues for an inch and a half; this is flattened on the side next 
the breast, with an oblong, window-like vacancy in it, crossed with 
five narrow bars, and covered with a thin, transparent skin, like the 
panes of a window; another thin skin of the same kind is spread over 
the external side of the labyrinth, which is partly of a circular form. 
This singular conformation is, as usual, peculiar to the male, the fe- 
male having the windpipe of nearly an uniform thickness throughout. 
‘She differs also so much in the colors and markings of her plumage, 
as to render a figure of her necessary; for a description of which see

Tne female is distinguished from the male by wanting the length- 
ened 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,
