SPECTACLED EIDER. _Arctonetta fischeri._ Range.--Coast of Alaska from the Aleutians to Point Barrow. Like the rest of the true Eiders, this species is black beneath and mostly white above. The head is largely washed with sea green, leaving a large patch of white, narrowly bordered by black around each eye, thus resembling a pair of spectacles. The nests are made of grass and seaweed and lined with down; they are placed on the ground in clumps of grass or beneath overhanging stones. The five to nine eggs are an olive drab or greenish color. Size 2.70 × 1.85. Data.--Point Barrow, Alaska, June 15, 1898. Six eggs. Nest of moss and down in a hollow in dry tundra. Collector, E. A. McIlhenny. 159. NORTHERN EIDER. _Somateria mollissima borealis._ Range.--North Atlantic coast, breeding from Labrador to Greenland and wintering south to New England.

The nesting habits are the same as those of the other Eiders. Six to ten eggs generally of a greenish drab color. Size 3. × 2. [Illustration 104: Steller's Duck.
