^SS- — 10 to 14 in number (Hantzsch) and occasionally 15 ; the shape is a rather short 
oval with the shell strong, fine grained, not very shiny, and smooth ; colour, greyish 
pea-green or blue-green. In two nests found by myself at Myvatn, June 1889, were 
9 and 10 eggs respectively. Three females with 10, 10, 12 young were also noted. In 
America, Brooks records 14 young brought off from one nest/ Mr. F. C. R, Jourdain 
informs me that the average size in mm. of 66 eggs is 61.33x44,47 mm. ; the maximum 
68x43.7 61 X47, and the minimum 58x45 and 61 X43.5. Average weight of 28 eggs 
7.33 gr. (6.36 to 7.98), Dr. Rey. Incubation by female alone extending to a period of four 
weeks (Hantzsch). The young fly in five to six weeks. Down very similar to that of the 
Golden-Eye, but somewhat paler (Dresser). Whitish-grey in bulk, but single sprays appear 
to be white (F. C. R. Jourdain). 
The small flank feathers are pure white. Dresser says that in one nest of each species 
of Golden- Eye he examined, the flank feathers of C. islandica were smaller. 
Pennant {Arctic Zoology, vol. ii. p. 574, 1784) gives no Latin name to this species, 
although he describes the male Hrafn-ond, Olaflen, Iceland, "with a crested head, black 
above ; under side of the neck, breast, and belly white ; legs, saffron-coloured. Inhabits 
Iceland. Whether a variety of the former ? for the Icelanders style that species Hrafus- 
aund." Pennant may therefore be said to have first described the species, although Gmelin 
is responsible for the Latin name. 
Young in Down. — There is very little difference between the young in down of Barrow's 
Golden-Eye and the Golden-Eye except in the colour of the feet and the size and shape 
1 The instances in which 23 and 24 eggs have been found in one nest are directly due to two ducks laying together.
