Four eggs of the Prairie Horned Lark are of a poiuted oval form 

 and arc slightly glossy. They vary both in size and in markings : 

 the two from Winnebago are smaller and have the ground-colour 

 greenish-white thickly mottled all over with yellowish-brown and 

 grey ; while, of the two from Mount Carroll, one has the ground- 

 colour greenish-white marked with olive-brown and grey, the 

 markings being mostly concentrated in a heavy confluent ring 

 round the larger end, and in the second the ground-colour is 

 whitish, densely and finely marked all over with light brown and 

 lilac, forming an indistinct zone round the larger end. Three 

 eggs measure respectively : -88 by -58 ; '93 by -63 ; '95 by '67.

Four eggs of the Texan Horned Lark are very similar to those 

 of 0. leucolcema, but are rather smaller and of a more blunt oval 

 form. In one example many of the markings take the form of 

 blotches, and two examples have black specks or hair-lines across 

 the larger end. They measure respectively : '77 by '58 ; '78 by 

 6 ; -81 by -58 ; -82 by '58.
