FALCO COMMUNIS, PEREGRINE FALCON. 341 



no description has liitherto appeared. A set now in the Smithsonian 

 was collected by Dr. Hay den in the Wind River Mountains, iu June, 

 18G(). They are rather unusually pointed at the smaller end, though 

 probably other examples might tend more nearly to the ordinary sub- 

 spherical shape prevailing among the eggs of rapacious birds. They 

 measure 2 inches in length by a trifle over li in breadth. The ground 

 color is dull white, but scarcely apparent, so thickly is it clouded over 

 with dull brown, forming here and there })atches of deeper shade. In 

 one specimen there is a decided purplish tint. To this identification of its 

 breeding range we may append the notice of its unfledged young, found 

 by Dr. Heermann near San Francisco.
