The eggs of the Yellow-billed Skimmer resemble those of 

 B. melanura, but are smaller. Some of the specimens are of a 

 remarkably narrow, elongated form. They measure from 1-33 to 

 1-64 in length, and from 1-12 to 1-17 in breadth.

The eggs of the Indian Skimmer are of a broad oval form, more 

 or less pointed at the smaller end. The ground varies from pale 

 cream-colour to pale buff, and, when the eggs are fresh, it is fre- 

 quently tinged with grey, green or pink. The markings, which 

 consist of bold streaks and blotches, are of a reddish-brown or 

 chocolate-brown colour, and sometimes they are so int Tis-ely dark 

 as to appear almost black. There are also the usual underlying p le 

 ]narple markings. As pointed out by Mr. Hume, the streaks 

 frequently lie at an angle with the longitudinal axis of the egg. 

 The eggs measure from 1-45 to 1'75 in length, and from 1"05 

 to 1*3 in breadth.
