'T'PIIS very feldom vifits the fouthern part of this ifland ; yet 

 Mr. Boys informs me, that he had a defcription of a bird fliot 

 in {he Jfiand of Thanet, M^zrc^ 1786, which could be no other than 

 a male of this fpecies.

4- VELVET D. 



'T^HE Scoter and Velvet Duck are grtatly finnilar in plumage, the 

 l-aft chiefly differing from the former in having the white 

 mark beneath the eye, and a band of the fame acrofs the wing ; 

 but internally they differ much : the male of the Scoter is totally 

 - without a labyrinth, or enjargement of the windpipe, in any part ; 

 but the Velvet Duck has a very confpicuous fwelling, of a roundifh 

 form, about the fize of a CmaU walnut, at about two thirds of its 

 length ; though at the entrance into the lungs there is no real la- 

 byrinth, only an enlargement.

'X'HE bill in young birds is black. This fpecies is very com- 

 mon at New Grenada, in South America, and is frequently 

 kept tame in the farm-yards between the tropics, but is apt to be 

 quarrelfome, and will often fly away. The Spaniards call the bird 

 Pije/ic, from its voice ; the Englijh, Main-Duck. This is fre- 

 quently brought into Europe, and has propagated in an aviary at 

 Shonbrun, in Siveden,
