 1*55 in breadth.

The eggs of the Great Tern are of a broad, pointed oval form. 

 The ground varies from cream-colour to pale buff and is often 

 tinged with pink. The surface-markings consist of spots and small 

 blotches of deep chocolate or blackish brown, and these are almost 

 invariably blurred and smudged at the margin. The underlying 

 markings are of a pale purple colour and are also blurred and ill- 

 defined. The markings of both kinds are equally, and not very 

 thickly, distributed over the whole shell. The eggs measure from 

 2*45 to 2-55 in length, and from 1-65 to 1*8 in breadth.
