BIRDS* EGGS. 



VOL. II. 



Sub-Class CAB.INAT53. 

 Order CH ARAB RI I FORMES. 



THE eggs of the birds of this Order are double-spotted, with the 

 exception of those of Hydrophasianus chirurgus and Dromas ardeola, 

 which are quite unmarked. 



The texture of the shell and the amount of gloss are very variable. 

 The shape also varies, but is chiefly of two types, the eggs of the 

 Plovers and Sandpipers being generally pyriform, whereas those of 

 the other groups are chiefly of an oval form. 



There is a great similarity between the eggs of many of the birds 

 of this Order and those of some of the Gulls and Terns on the 

 one hand, and of the Rails on the other.

The eggs of Hartlaub's Sheathbill are generally of a regular oval 

 form, but a few are somewhat sharply pointed. They are entirely 

 gloss -less and the shell is rather rough. The ground varies from 

 pale buff or light stone-colour to a rather bright pinkish buff, and
