The eggs of the Cayenne Lapwing vary from pyriform to a regular 

 oval shape. They have little or no gloss. The ground-colour is 

 olive-buff, spotted and blotched with black and dark brown, and 

 underlying pale purple. On some specimens the markings are coarse, 

 on others small and delicate. The examples in the Collection vary 

 greatly in size, the smallest measuring 1*6 by 1-12 and the largest 

 1-95 by 1-4.
