The eggs of the Grey-capped Gull in the Collection are of a 

 pretty regular oval form, but some are compressed or pointed at the 

 small end. The ground varies from dark cream-colour to olive-buff, 

 and there is a decided tinge of green running through the paler 

 specimens. In three-fourths of the examples the markings, which 

 consist of spots, lines, and medium-sized blotches, are evenly distri- 

 buted over the egg ; but in the remainder the markings form a very 

 irregular cap or zone at the large end. The surface-markings are 

 yellowish brown, rufous brown or blackish brown, and the under- 

 lying ones, which are inconspicuous, are very pale purple. The eggs 

 measure from 1-96 to 2'5 in length, and from 1-5 to 1-7 in breadth.

The eggs of the Spot-winged Gull are remarkably varied both 

 with regard to the ground-colour and the disposition of the mark- 

 ings. They are of a regular oval form, sometimes pointed. Three 

 eggs are of a pale unspotted blue colour ; another is blue, sparingly
