The eggs of the Large-billed Buzzard-Hawk are spheroidal in shape, 

 somewhat rough in texture, and devoid of gloss. The ground-colour 

 in all the examples in the Collection is dull white, but the markings 

 are varied. One specimen is thickly covered with specks and 

 smears of pale purple and rusty brown ; a second is marked, chiefly 

 on one half of the egg, with smears of reddish brown, showing 

 some blackish spots and some pale neutral-tint underlying blotches ; 

 a third is freckled all over and blotched at one end with rufous ; 

 and a fourth is sparingly speckled with neutral-tint and dark brown. 

 They measure respectively : 1-8 by 1-5 ; 1-85 by 1-48; 1 '8 by 1-43; 

 1-8 by 1-5.
