Genus ARGYA, Less. 



The eggs of the birds of this genus are normally of a regular 

 oval form, but it is not unusual to meet with eggs which are of an 

 elliptical or spheroidal shape. They are highly glossy. 



The eggs of all are of a rather dark unspotted blue, varying in 

 intensity of tint even in those of the same species. In fact, when 

 large series of eggs are examined, it will be found that a gradual 

 blending of colour takes place between the eggs of one species and 

 those of another. The eggs also vary immensely in size.
