In summer the head, neck, lower back, tail and 

 edge of the wings, and .whole under plumage, pure 

 white ; the mantle and wings pale grey ; quills 

 crossed by a black bar, broad on the first but after- 

 wards rapidly narrowing upon the others, and on 

 the sixth scarcely an inch in breadth; the first 

 quill with a white tip ; the bill is a pale dull yel- 

 low, angle of the mandible reddish orange ; legs 

 and feet grey, tinted with light red. In winter 

 the head is streaked with pale greyish brown. 



The next two birds closely resemble each other 

 except in size, and also the Herring Gull, differing 

 and both at once distinguished from the latter by 

 the quills wanting the black at their extremities. 'An 

 example will be seen in our next plate, representing
