Genus POLIOPTILA, Sclater. 



The eggs of the Gnatcatchers are all very similar one to another 

 and cannot be separated. They are of a rather broad oval shape 

 and exhibit but little gloss. The ground-colour is white, bluish- 

 white or very pale blue, and the whole shell is thickly speckled and 

 spotted with deep chestnut, reddish brown, and lavender or lilac. 

 The markings are frequently more dense and of larger size at the 

 broad end than elsewhere, and form an imperfect cap.
