The eggs of the Glaucous Gull in the Collection, although not 

 numerous, show quite an extensive variation. They are of a pointed 

 oval form. A few are pale blue, marked very sparingly with 

 blackish spots and here and there a blotch. Others are yellowish 

 grey, marked with some brown spots and huge blotches. Others 

 again form a remarkable type, quite unique among Gulls' eggs. 

 The ground is of a pale pink and the whole shell is densely covered 

 with streaks, clouds, and smears of brick- red and underlying pale 

 purple. The common type of egg has the ground of an olive-grey 

 or pale buff colour, and this is evenly marked all over with spots, 

 lines, and small blotches of yellowish and dark chocolate-brown, and 

 the usual underlying grey or pale purple. The eggs measure from 

 2-9 to 3-6 in length, and from 1-9 to 2-4 in breadth.
