Eggs. Four in number, pear-shaped, and of a creamy-buff to 

 a clay-coloured ground, with small blackish spots and lines, 

 sometimes forming small blotches near the larger end of the 

 egg ; the underlying spots purplish-grey, very small and 

 scarcely visible. Axis, i'3~i"5 ; diam., o'9-5i'o5. 



Mr. Robert Read says that he has noticed that the eggs 

 of this bird vary considerably in the ground-colour, accord- 

 ing to locality, those laid on the dark pebbles near inland 

 lakes and rivers being much duller than those laid on the 

 bright yellow sea-sand. As far as my experience goes, the 

 eggs, though laid in a sandy hollow, are generally surrounded 

 by pebbly beach, many of the stones of which so nearly re- 

 semble the eggs themselves as to make the latter very diffi- 

 cult to find.
