STELLER'S EIDER. 177 



not white as in S. mollissima ; the curious elongated innermost secondaries are 

 black, in the Common Eider these are yellowish-white. These peculiar feathers, 

 although found in other Somateria, are absent in Steller's Eider. There is a 

 black chevron-shaped mark under the chin ; fore-neck white ; breast a creamy- 

 buff; the rest of under parts intense black, with a white spot on each side on 

 the flank. 



The female is smaller and redder in plumage than the Common Eider. In 

 both the male and female the feathers on the centre of upper mandible reach as 

 far forward as the nostrils, and extend beyond those on the sides of the bill ; the 

 reverse is the case in the Common Eider. In Somateria v-nigrum, the feathering 

 on the bill is the same as in 5. mollissima. 



In the " eclipse " dress the male Eider, in this and the preceding, is so altered 

 as to be scarcely recognizable ; the whole bird being nearly coal black. It is said 

 to be very good eating. The adult male and female are beautifully figured in 

 I/ord Lilford's " Coloured Figures of the Birds of the British Islands."

 as it was formerly named in error, inhabits the Arctic and Subarctic coasts of the 

 Northern Hemisphere, and its breeding range extends from the Varanger Fjord, 

 in the west, to Bering's Straits and Sea. It is recorded on the Prybilov and 

 Kurile Islands, some wintering on the latter. It is very common both in Northern
