guished by the height of the maxilla as compared with the dis- 

 tance from the feathered edge at base of the bill to the anterior 

 edge of nostril. In the female Barrow's golden-eye these 

 measurements should be equal. 



Downy young — Top and sides of head, brown ; neck, chest, and 

 sides, pale; throat and under parts, white. 



Eggs — Six to ten in number, grayish pea-green in color, and meas- 

 ure 2.40 by 1.60 inches. 



Habitat — Breeds from Quebec and Washington, the mountains 

 of Oregon, south in the Rocky Mountains to Colorado, north 

 to Chilkat Peninsula, Alaska, Fort Anderson, and southern 

 Greenland, and in Iceland. Winters chiefly north of the United 

 States, from southern Greenland and southeastern Alaska, rarely 

 to North Carolina, Ohio, Indiana, Illinois, Minnesota, South 

 Dakota, Colorado, Utah, Idaho, Oregon, and California. Acci- 

 dental in Europe.

 breeds throughout these limits. We see the 

 Barrow's golden-eye among the lakes and rivers

 bird choosing the hollow of a tree near some 

 stream or lake for its nesting-place. In the
