GLAUCOUS GULL. 619 



rocks and the projecting ledges of cliffs on the sea-shore. 

 The egg is of a stone colour, spotted with ash grey and/ 

 two shades of reddish-brown, and measures two inches nine 

 lines in length, by one inch and eleven lines in breadth. 

 One of these Gulls disgorged a Little Auk when it was 

 struck by the shot, and proved on dissection to have a 

 second in its stomach. Sir James C. Ross mentions, that 

 this species was found at Felix Harbour, and along the 

 line of the western shore of Prince Regent's Inlet ; and 

 Mr. Audubon includes it in his Ornithology of the United 

 States and North America. 



The adult bird has the bill yellowish-white, the inferior 

 angle of the lower mandible reddish-orange ; irides straw 

 yellow ; all the plumage nearly white, but with a tinge of 

 skimmed-milk blue over the back and wing-coverts ; pri- 

 maries white, reaching but little, if any, beyond the end 

 of the tail ; legs and feet flesh colour. 



Old males have been taken measuring, from the point of 

 the beak to the end of the tail-feathers, thirty-two and 

 even thirty-three inches; the wing, from the carpal joint 

 to the end of the longest quill-feather, nineteen inches. 

 In winter the head and neck are slightly streaked with 

 ash grey. 



The bird killed by Mr. Edwards on the Severn, and 

 which that gentleman very kindly sent up for my use in 

 this work, measured in its whole length twenty-seven 

 inches and a half; the wing seventeen inches and three- 

 quarters. 



The young Glaucous Gull obtained in the London 

 market has the bill pale brown at the base, the point dark 

 horn colour ; the irides dark ; head, neck, back, and wing- 

 coverts a mixture of pale ash brown and dull white; 

 scapulars and tertials transversely barred with pale brown, 

 and tipped with greyish-white ; primaries and secondaries
