Genus NEOPHRON, Savigny. 



The eggs of the two species of Vultures of this genus are quite 

 inseparable, and both pass through the same variations of size and 

 colour. 



They are normally of a regular oval shape, but elliptical, bi- 

 conical, and even spheroidal examples are to be met with. The 

 shell is rough but has, at times, a slight amount of gloss. 



The coloration is extremely varied. The ground is white, cream- 

 colour, pale grey, or rufous white, and while some specimens are 

 marked with only a few reddish-brown specks at the larger end, 

 others are covered with confluent masses of deep reddish brown to 

 such an extent that little of the ground-colour remains visible. 

 Between these two extremes every variation in shade, extent, and 

 intensity of markings is found. Some specimens are almost uni- 

 formly marked all over, while many have a large cap of richer 

 colour at one end.
