Eggs of the Chough vary in shape from a broad or regular oval 

 to a somewhat pointed oval, and are almost devoid of gloss. The 

 ground is white, creamy-white, or j^ale greenish-white, marked all 

 over the shell, sometimes sparingly, sometimes densely, with spots 

 and small blotches of umber-brown and lilac-grey of different shades, 

 the markings being usually more numerous and rather larger at 

 the broad end. 



European eggs vary in length from 1-47 to 1'62, and in breadth 

 from 1-01 to 1-lG. 



An Algerian egg measures 1*42 by 1. 



The egg laid by the larger Tibetan race, named Frecjilus 

 Mmalayanus, Gould, is much larger than any other specimen in 

 the Collection and measures 1"74 by 1'2. It does not differ in any 

 other respect.
