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 1'53 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 intsnsely dark 

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

 purple 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.
