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

 and are 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 aud 

 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 "SS ; -78 by 

 •6 ; -81 by -58 ; -82 by -SB-.
