 underlying purplish-grey. The markings are very evenly distributed 

 over the entire surface of the egg. Four examples measure

Three eggs of the Rufous Rock-Pipit closely resemble those of 

 A. sordidus ; the fourth, as shown in the Plate, is of quite a different 

 type, the ground-colour being white rather sparingly marked with 

 small blotches and spots of purplish-brown and lilac-grey, the 

 markings being most numerous round the large end, where they 

 form an irregular zone. They measure respectively : -81 by '61 ; -87 

 by -62 ; -89 by -65 ; -92 by -64.
