deposited early in June and are two or three in number. Should 

 the eggs be removed the parent will renew the complement, but 

 only one or two will be laid. The period o£ incubation is 

 about three weeks. The young are downy and pure white on 

 their first appearance, but soon change to gray with darker mot- 

 tlings. {Turner.) 



On June 4th, near St. Michael, the first nest was found. It 

 was placed on a small islet, a few feet across, in the centre of a 

 broad, shallow pond. The structure was formed of a mass of 

 moss and grass, piled up a foot or more high, with a base three 

 feet across, and with a deep central depression lined with dry 

 grass. There was a single egg. The female as she sat on the 

 nest was visible a mile away, and not the slightest oppor- 

 tunity was afforded for concealment on the . broad surrounding 

 flat. Other nests were of the same character and contained from 

 one to three eggs. {Nelson.) Mr. Macfarlane's note under L. 

 glaucous probably refers to this species.

Several nests of this species, and the parent bird, were procured 

 on the shores of Franklin Bay, arctic coast, early in July, 1863 

 and 1864. {Macfarlane.) During Captain Ross's and Sir Edward 

 Parry's first voyages many specimens of this gull were obtained 

 in Davis Strait, Baffin Bay, and at Melville Island. {Richard- 

 son) This species is far less common in Cumberland Gulf than 

 the Glaucous Gull ; on the Greenland coasts, however, it is the 

 most common species except the Kittiwake. {Kum^lin.)
