GULL. NATATORES. LARUS. 509 



PLATE 97. represents this Bird of the natural size, from 

 a specimen that was killed upon the Northumbrian 

 coast, in April 1828, when it still exhibited a few dark 

 streaks upon the crown, and hind part of the neck, in- 

 dicative of the winter plumage. 



Bill, from the division of the feathers on the forehead to General 

 the tip, two inches and a half long ; of a pale gamboge tion. nP 

 or primrose-yellow ; the angular projection of the lower Adult. 

 mandible orange-red, with a dusky spot in the centre, 



Head, hind part of neck, whole of the under plumage 

 and tail, pure white. Mantle and wing-coverts grey- 

 ish-black. Greater quills black ; the first one tipped 

 with white for upwards of two inches, the next having 

 a white spot about an inch from the end, and the ex- 

 treme tip white ; the rest white only at their very points. 

 Tertials and secondaries deeply tipped with white. 

 Legs pale flesh-red, with a livid hue. 



In the young state, the colours of the plumage, and their Young. 

 disposition, are very nearly the same as in the young of 

 the Herring Gull, and the changes annually undergone 

 are also similar.
