The Hijlory ^ ANIMALS, 435 
one of them have fo much as named it. I have the fkin of that which I killed now 
■ preferved, and the colouring, though fo Ample and uniform, ftrikes every eye that 
fees it, by it’s Angularity. Linnaeus has evidently mentioned it, and gives the autho¬ 
rity of his countryman Rudbeck, that it is a native of Sweden, and lives about frefh 
waters: but that author calls it a rare fpecies 3 he calls it Anas Auviatilis rufa roftro pe~ 
dibufque cinereis.

The general Agure of this fpecies has occaAoned thofe, who diflinguifh the duck 
and goofe-kinds, to refer this to the former, though the bignefs would have natu¬ 
rally enough referred it to the latter ; it is at leaft equal to our common goofe in Aze : 
the head is large, and of a very Angular appearance; it is very rounded and protube¬ 
rant ; the eyes are large, and their iris is of an orange fcarlet; their afpedt is very 
Aerce; the beak is long and large, it is thick at the bafe, but Aatted in all other parts, 
and rounded at the end : it’s colour is a dufky orange; the noftrils are oval, large, 
and black: at the bafe of the beak there is a large protuberance of a naked, Aefliy 
matter, of a high and elegant red colour, and the eyes are alfo furrounded with a 
naked, Aefhy matter, of the fame colour, and of a corrugated or wrinkled furface. 
The top of the head is of a deep black, but there is an elegant green diffufed all 
through that colour, and in fome lights fhewing itfelf almoft folely, without any ap¬ 
pearance pf the black: the top of the head is ornamented with a creft, formed of a 
very large tuft of black feathers: the back, wings, bread, and belly, in fhort, the 
whole bird, are of the fame blackifh-green with the head, and that very beautiful, only 
the tops of the wings are white. 
The legs are long and thick, and of a beautiful orange fcarlet; the toes are long, 
and the membrane which connedls them, and forms the web of the foot, is ferrated: 
the hinder toe is very fhort and inconAderable ; the inner one of the three anterior is 
much Aiorter than the outer: the legs are not Atuated fo backward as in many fpecies, 
and hence the bird can walk on land better than moft. 
It is a native of the South American iAands, and lives on the large frefh water 
lakes there. It frequently leaves the water, and enjoys the ferene air on fhore. The 
writers on the Brafiiian animals have deferibed it; and we have lately had the duffed 
fkin fent us over as a curiofity : the mixture of green with the black in it is very 
beautiful.

This is another of the Brafiiian ducks, and is a very Angular, as well as beautiful, 
bird ; it is fomewhat fmaller than our common goofe, but conAderably larger than the 
duck : the head is large and rounded ; the eyes are bright and piercing, but not large; 
their iris is of a pale hazel, with an admixture of yellow : the beak is large, and of 
a Angular ftrudture ; it is thick at the bafe, Aatted all the way of it’s length, and round¬ 
ed, but withal fomewhat bent at the end, the unguis, which terminates it, evidently 
turning down. 
The head is of a fnow-white, but variegated, in an elegant manner, with a few 
black feathers: the bafe of the beak is ornamented with a Aefhy protuberance, but this 
is not red as in the former fpecies, but black, fpotted with white : the neck is of 
the fame elegant white with the head, and is in the fame manner variegated with a 
fmall number of black feathers: the bread: and belly are white ; the back and wings 
are of a deep black, but with an admixture of a deep gloffy green : the tail is Aiort; 
the legs are long and robuft, and are of a greyifli colour.
