Eggs of Dupont's Lark are of a rather broad, slightly-pointed, oval 

 shape and are somewhat glossy. The ground-colour varies from 

 white or greenish- white to pale buff, and is spotted and blotched, 

 sometimes densely, with yellowish-brown and dull lavender-grey. 

 The markings, as a rule, are heaviest towards the larger end, where 

 they occasionally form a more or less irregular zone. They measure 

 from -91 to '97 in length, and from -66 to '7 in breadth.
