The eggs of the Western Madagascar Magpie-Eobin, which show 

 considerable variation, resemble those of Copsychus saularis, though 

 the markings are certainly of a duller brown tint. The ground- 

 colour varies from the palest greenish white to a greenish blue, 

 and the markings are of various shades of yellowish brown and 

 pale reddish brown. The eggs vary from '8 to -9 in length, and 

 from -61 to -65 in breadth.

The eggs of the Indian Shama resemble those of Copsychus 

 saularis, and, like them, are very varied both with regard to the 

 colour of the ground and the distribution of the markings. One 

 clutch of eggs in the Collection cannot, however, be matched by any 

 of the eggs of the other species, the ground being a dead white, 

 without any trace of green. On the whole, the eggs of the present 

 species are rather smaller than Indian eggs of C. saularis, measuring 

 from '77 to -92 in length, and from -61 to -65 in breadth.
