ICELAND GULL. 581 



Since the publication of the previous edition of this 

 work, an adult bird has been taken in Lincolnshire, and a 

 young one in Devonshire. 



The Iceland Gull sometimes makes its appearance in 

 winter at the mouth of the Elbe ; it has also been taken in 

 Holland and in Belgium ; the latter circumstance I learn 

 by the publication of a most useful and interesting volume 

 on the vertebrate animals of Belgium, written by M. 

 Edmund de Selys-Longchamps, of Liege, and which has 

 very recently been received in this country. 



In the adult Lesser White-winged Gull the bill is small 

 and yellow, the angle of the under mandible red ; the irides 

 straw yellow ; head and neck all round pure white ; back, 

 wings, and all the wing-coverts very pale ash-grey ; pri- 

 mary quill-feathers wholly white ; upper tail-coverts and 

 tail-feathers white ; chin, throat, breast, and all the under 

 surface of the body and tail pure white; legs flesh- 

 coloured. 



The whole length twenty-two inches ; the pointed 

 ends of the wings, when closed, reach two inches beyond 

 the tail. 



From September to the beginning of April, while in 

 their winter -plumage, Faber says, they have grey spots 

 on their head and neck. 



Mr. Mitchell's young bird has the bill pale yellow at the 

 base, the anterior half horny black; the irides dark brown; 

 head and neck dull white, clouded with pale ash-brown ; 

 the back the same colour ; secondaries, tertials, and all the 

 wing-coverts dull white, marked transversely with pale 

 brown angular streaks ; primaries white ; tail-coverts and 

 tail-feathers greyish white, the latter marked across with 

 broadish lines of pale brown, which are more numerous 

 about the base than towards the end ; chin dull white ;
