Young Female, in first winter. 
The colours of the young bird, in its first plumage, are unknown ; but in 
its second plumage, in autumn and winter, it presents the appearance 
exhibited in the plate. The bill is pale flesh-colour, its edges black, and 
the unguis bluish-white ; the feet flesh-colour, the claws dusky. The head 
and upper part of the neck are white, tinged above with grey, the lower 
part of the neck all round, the fore part of the back, the scapulars, the fore 
part of the breast, and the sides, blaclcish-grey ; paler beneath. The hind 
part of the back and the upper tail-coverts are ash-grey ; as are the wing- 
coverts; but the secondary coverts are greyish-black in the middle; and all 
the quills are of that colour, the secondaries margined with greyish-white; 
the- tail-feathers dusky-grey, broadly margined with greyish-white. The 
dark colour of the fore part of the breast gradually fades into greyish- 
white, which is the colour of the other inferior parts ; excepting the axillar 
feathers, and some of the lower wing-coverts, which are white. 
Length of an individual in this plumage, kept four years— to end of tail 
26 inches, to end of claws 25; extent of wings 55; bill along the ridge 23, 
from frontal angle 2-J; tarsus 2 ,"4; hind toe yV ; its claw , 4 |; middle toe 2y, 
its claw iV Weight 2 lbs. 13 oz. The bird very poor. 
In an adult male preserved in spirits, the roof of the mouth is moderately 
concave, with five series of strong conical papillm directed backwards. The 
posterior aperture of the nares is linear, margined with two series of 
extremely slender papillae. The marginal lamellae of the upper mandible 
are 25, of the lower about 45. The tongue is 2 inches 5 twelfths long, 
nearly cylindrical, with strong pointed papillae at the base, and on each side 
a series of flattened, sharp lamellae, directed backwards, together with very 
numerous bristle-like filaments. It is fleshy, has a soft prominent pad at the 
base above, and towards the end has a median groove, the point rounded, 
thin, and horny. The oesophagus, which is 17 inches long, has a diameter 
of 9 twelfths at the upper part, and at the lower part of the neck is dilated 
to 1 inch. The pro ventricular glands are cylindrical, simple, and arranged 
in a belt nearly 1 inch in breadth. The other parts were removed. 
The reddish tint on the head affords no indication of the age of the bird, 
some individuals of all ages having that part pure white, while others have 
it rusty. The same remark applies to our two Swans.
