Anas niger Aldrov. Will. Orn. 278 — A- fusca, Linn. Syst. i. 196. Perm. 

 Brit. Zool. ii. 583. Temm. Orn. ii. 855. (Trachea, Lin. Trans, iv,

 low, whitish. Tumour at the base of the bill less. Breeds, according to 

 Temminck, in the Arctic Regions, but it is not mentioned by Fabricius or

174. O. nigra. Black Scoter. — Plumage entirely black. 



A. niger, Will. Orn. 180 A. nigra, Linn. Syst. 1. 196. Penn. Brit.

Size of the preceding. Bill with the middle at the base hollowed. Irides

 tion of the female Scoter, by Montagu, has a reference to this species. 



As a straggler may be noticed the O. perspicillata (A. per. Temm. Orn. ii. 

 853.) It agrees with O. nigra in wanting the wing spot, and in having the 

 plumage black, but the nape and a frontal band are white. The bill is yel- 

 low, with a black mark on each side, having in front a space of grey. It is 

 said by Temminck to have occurred in Orkney.

 bill extending up the forehead, and divided by a triangu- 

 lar projection of feathers.
