Eggs of the Pink-billed Lark are of a somewhat pointed oval 
shape and slightly glossy; the ground-colour is white or pale 
greenish-white, spotted all over, especially round the larger end, 
with olive-brown and purplish-grey. In four eggs from Wolvehoek 
the ground-colour is white and the markings are mostly very fine, 
but in the set from Heilbron the ground-colour is pale greenish- 
white and the markings are much bolder, many taking the form of 
small rounded blotches. They vary from ‘74 to °8 in length, and 
from °51 to ‘54 in breadth.

Eggs of the Sky-Lark vary from a pointed to a blunt oval form, 
but the majority are pointed and a few are pyriform. Many 
specimens exhibit a high gloss, others are comparatively dull. 
The ground-colour varies from dull white to grey and greenish- 
white, and is, as a rule, profusely mottled with various shades of 
brown and underlying purplish-grey or pale lavender. The 
markings are frequently tinged with olive, and occasionally with 
rufous; and while in some specimens they are evenly spread over 
the entire surface of the shell, in others they are disposed more 
densely at the broad end and form a cap or zone. Specimens 
measure from -85 to 1:02 in length, and from ‘61 to ‘72 in 
breadth.
