The eggs of the Short-billed Gull in the Collection are of a pointed 

 oval form. One example has the ground of a pale greenish colour ; 

 another of a full buff colour ; and two others of a greenish-grey 

 colour. The markings, which consist of spots, small blotches and a 

 few streaks, are of a chocolate or blackish-brown colour and are, 

 in all cases, more dense at the large end, where they form a more 

 or less broken cap or zone. Pour speoitnens measure respectively :

The eggs of the Glaucous-winged Gull are very uniform and 

 resemble the common type of egg of L. argentatus. The ground- 

 colour varies from pale creamy-buff to a pale buff, and this is evenly 

 spotted and blotched all over with yellowish and chocolate-brown, 

 sometimes approaching black, and underlying pale purple. A 

 few have, in addition to the normal markings, some lines and 

 scrawls. The eggs measure from 2'7o to 3'05 in length, and from 

 1-86 to 2 in breadth.
