The eggs of the Iceland GuU appear to be fairly uniform in 

 coloration. The ground-colour varies from a greenish grey to a pale 

 buff and this is marked, in most eggs evenly all over, in a few more 

 densely at the larger end than elsewhere, with spots and blotches of 

 chocolate and dark blackish brown and underlying pale purple. 

 Specimens vary from 2-5 to 2'75 in length, and from 1-75 to 2 in 

 breadth.
