from the collection of Walter Raine, taken by F. Baines at 

 Crescent Lake, Assmibora?, N.W. Canada, and made the 

 following remarks : — 



" The claim o£ this comparatively widely distributed 

 American species to a place on the British list rests on the 

 evidence of a single specimen found in Leadenhall Market 

 (see B. 0. U. List, 2nd ed. p. 177), and, as far as I am aware, 

 the eggs, down, and feathers have not yet been described by 

 any British Ornithologist, neither are they represented in 

 the National Collection. 



" Description. — Eggs. There are apparently two types : 

 those of the first type are pale olive-green, very much 

 like the eggs of the Pochard [Nyroca ferina) ; those of the 

 second type are pale olive-green tinged with brown, like 

 eggs of the Tufted Duck [N. fuligula). Shape closely 

 resembling those of the Tufted Duck. Size intermediate 

 between those of the Tufted Duck and Scaup. Texture of 

 shell finely grained, but rather coarser than in those two 

 species. Inner membrane distinctly^ reddish brown when 

 held to the light. 



'' Feathers. Three distinct patterns occur, as is also the 

 case with the nest-feathers of the Tufted Duck and Scaup: 

 no. 1 white, pale brownish at the base ; no. 2 a self-coloured 

 feather of pale chocolate-brown with paler centres, darker 

 towards the tip ; no. 3 same colour as no. 2, the tip, how- 

 ever, is slightly speckled, as with those of the Pochard and, 

 according to Mr. HeatlyiNoble, those of the Scaup. Though 

 I have not found this feather in the nests I have examined, 

 the feathers of the E-ing-necked Duck would, however, 

 appear to have one distinguishing characteristic — the extreme 

 tips of the speckled feathers are not white, as in those of 

 the Pochard and Scaup. It remains, however, to be proved 

 as to whether this is constant. 



" Size. The same as those of the Pochard, smaller and 

 narrower than Scaups, and much larger than those of the 

 Tufted Duck. 



" Down. Slightly paler than that of the Scaup ; inter- 

 mediate in colour between that of the Scaup and Pochard ;
