Family MIMID^E. 



Genus MIMUS, Boie. 



The eggs of the genus Mimus are much alike in their general 

 character. In all of them the ground-colour is of a light tint 

 varying from greenish blue to greenish grey, and the markings, 

 which are most variable in their combinations and tints, even in 

 eggs of the same species, consist of spots, blotches, and clouds of 

 many shades of purplish-brown and msset.

The eggs of the American Mocking-Thrush are usually of a broad 

 oval form. They vary from greenish to bluish white, and are 

 spotted, blotched, and clouded with various shades of reddish and 

 purple-brown and underlying lavender-grey. The markings are 

 generally densest at the broad end, where they often form an 

 irregular cap. Specimens measure from '9 to 1"07 in length, and 

 from '68 to "8 in breadth.
