Genus SIALIA, Swains. 



The eggs of the species of Sialia represented in the Collection are 

 of a broad oval shape and possess a considerable amount of gloss. 

 They are of a pale spotless blue colour, and are so much alike 

 in size and colour that, the eggs of the different species cannot be 

 separated from each another.
