The eggs of the Arctic Tern are, on the whole, somewhat smaller 

 than the eggs of the Common Tern. They do not, however, other- 

 wise differ, and they are subject to the same variations of colour and 

 shape. Among the specimens in the Collection are some which are 

 of a pale bluish white, very sparingly dotted with dark brown, and 

 one is quite unmarked. The eggs measure from 1-42 to 1-75 in 

 length, and from 1-03 to 1-2 in breadth.
