SPOROPHILA. 163 



Eggs of th.e Screaming Seed-eater are of a rather long oval 

 form and almost devoid of gloss. The ground-colour is white or 

 bluish-white, and the markings in most of the specimens are similar 

 to those of S. moreleti described above. A set of five eggs from the 

 Crowley Collection differs considerably, being heavily marked with 

 choeolate-brown blotches and markings, chiefly distributed around 

 tbe larger end. The measurements vary from -62 to -71 in length, 

 and from -47 to -5 in breadth.

Eggs of the Yellow-bellied Seed-eater are of an elongate oval 

 shape and devoid of gloss. Six are pale greenish-white, sparingly 

 marked with small blotches and some lines of chocolate-brown and 

 densely streaked, smeared and clouded with purplish-brown and

 brown cap. They measure from -65 to -71 in length, and from 

 •48 to -51 in breadth.
