Eggs of the Madagascar Wagtail vary from a broad to a narrow 
oval shape and are very glossy. The eggs in the Collection are of 
three types. In one the ground-colour is pale greyish-green, and 
the whole surface of the shell is densely mottled with greyish- 
brown and lavender. In another, the eggs are dull white, blotched 
and mottled with umber-brown and lavender. In the third type, 
the egg is cream-colour, densely mottled with purplish-brown and 
lilac-grey. They vary from -71 to °8 in length, and from 57 to 
-63 in breadth.

Eggs of the Grey Wagtail are of a broad pointed oval shape and 
very glossy. The commonest type of egg is pale grey or bluish- 
white or sometimes cream-colour, mottled all over with light brown 
of various shades. Another type, which appears to be much less 
common, is white or greyish-white, mottled with umber-brown 
and lavender-grey. In this type the markings are most dense on 
the broad end, where they form a more or less confluent cap. A 
few examples in a large series have one or two black hair-lines at 
the broad end of the egg. Specimens measure from °7 to °8 in 
length, and from -54 to ‘6 in breadth.
