Six eggs of the Transcaspian Horned Lark are of a pointed oval 
form and glossy. ‘They vary somewhat in appearance: four have 
the ground-colour greenish-white, thickly mottled all over with 
olive-brown and grey, the markings being most numerous round 
the larger end, where they form a more or less defined zone, while 
one has also well-defined black hair-lines on the larger end. A 
fifth specimen has the ground-colour dull yellowish-white, the 
markings fewer and often in the form of blotches, while in the 
sixth specimen the whole surface is thickly but indistinctly mottled 
with fine speckles of brown and grey. They measure respectively : 
°89 by °62; 9 by 66; -95 by °68; (2) -98 by -69; -99 by °68.
