The eggs of the Dingy Rock-Pipit are of a blunt oval form, 
approaching the elliptical, and are but very slightly glossed. They 
are white, thickly mottled and blotched with deep umber-brown and 
underlying purplish-grey. The markings are very evenly distributed 
over the entire surface of the egg. Four examples measure 
respectively: ‘9 by ‘67; -9 by °66; 89 by 65; :92 by ‘67.

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 
forman irregular zone. ‘They measure respectively : ‘81 by ‘61; °87
