The eggs of the Bed-backed Buzzard are of a broad oval or 

 elliptical shape, slightly rough, and devoid of gloss. They are 

 dull white, marked with rich chocolate-brown and underlying 

 purplish-grey blotches, or, in many cases, with yellowish-brown and 

 pale rufous specks and spots. In some specimens the markings are 

 pretty evenly distributed over the shell, while in others they are 

 chiefly restricted to one half of the egg. They measure from 2-2 to 

 2-4 in length, and from 1'7 to 1'9 in breadth.

The eggs of the Jackal Buzzard are of a broad oval or ellip- 

 tical shape, rather rough in texture and without gloss. They are 

 white, smeared, blotched, and spotted with dull reddish brown and 

 brownish pink. In one example the larger markings are chiefly on 

 the broad end, in two others on the smaller. A fourth specimen is 

 faintly and sparingly marked all over. They measure from 2-15 to 

 2-4 in length, and from 1'8 to 1*93 in breadth.
