The eggs of the Red-billed Gull in the Collection are very similar 

 to each other. They are of a rather narrow oval shape. The 

 ground is of an olive-buff colour, and this is marked with well- 

 defined small sjjots and blotches of yellowish and chocolate-brown 

 and underlying pale purple. In three examples there is a distinct 

 tendency for the markings to form an irregular zone round the 

 large end. Four specimens measure respectively : 2'2 bj' l"-i.3, 2-\o
