 Family MEGAPODIIDiE. 



The eggs of the Megapodes are usually lengthened and narrow. 

 They are either elliptical or biconical or, occasionally, of a regular 

 oval form. 



The shell is thin and brittle, rough to the' touch, covered with 

 minute pores and glossless. 



The shell itself appears to be always white, but it is almost 

 invariably covered by a thin calcareous film, which, however, is easily 

 removed and is of a coffee-brown, reddish-brown or pink colour. 



It is well-known that the Megapodes deposit their eggs in. mounds 

 of earth' and vegetable matter. During the time that the eggs lie 

 buried in these mounds they undergo considerable changes, and 

 when discovered they seldom exhibit their original colour. 



The eggs of the Megapodes are remarkably large when compared 

 with the size of the bird.

The eggs of the Nicobar Megapode when first laid are of a ruddy- 

 pink colour. After being buried, they turn to pale yellowish-brown, 

 buff or stone-colour. The outer film frequently flakes ofi' in spots, 

 specks and large blotches, causing the shell to be mottled with white. 

 The eggs measure from 3 to 3-4 in length, and from 1-9 to 2-25 in 

 breadth.
