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 pale 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 1-16. 



An Algerian egg measures 1'42 by 1. 



The egg laid by the larger Tibetan race, named Fregilus 

 Jiimalayanus, 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.
