The eggs of the Cape Ground-Eobin are for the most part of a 

 blunt oval form and fairly glossy. The ground-colour is a bright 

 greenish blue, and this is spotted, mottled, and blotched, generally 

 rather thickly, and more densely, at the larger end of the egg than 

 elsewhere, with rich reddish brown and imderlying pale purple. On 

 some eggs the markings are smaller and less numerous on the smaller 

 half of the shell. They range in size from -70 to "82 in length, and 

 from "58 to "60 in breadth,
