The eggs of the Eock-Thrush vary in shape from a broad to a 

 narrow oval, and have a considerable amount of gloss. The ground- 

 colour is a pale delicate bluish green, either plain or marked with a 

 few small brown specks, usually on the larger end. They vary from 

 •99 to 1-13 in length, and from "7 to "81 in breadth.

Resembling the eggs of the preceding species, M. saxatilis, in 

 size and ground-colour, those of the Western Blue Eock-Thrush are 

 more easily divisible into a plain and a spotted type, and in the 

 latter the spots are more numerous. In the Museum series these 

 two types are about equally represented.
