Summer 
Plumage. 
486 NATATORES. LARUS. GULL. 
Forehead and crown white, tinged with grey. Nape, and 
back part of the neck, and upper parts of the body, 
blackish-grey, tinged with clove-brown, the edges of the 
feathers being fringed with greyish-white. Scapulars 
edged with white. Greater coverts grey, deeply mar- 
gined with white. First four primary quills having 
their outer webs and tips black, and the inner webs 
greyish-white. Under, plumage white. Tail white for 
two-thirds of its length, terminated by a broad black 
bar, slightly concave or forked. Legs and toes livid or 
pale flesh-red. Two or three light grey feathers indi- 
cating the approaching change of plumage are seen up- 
on the back; and this change, when perfected, brings 
the bird to the state of the Little Gull of Monracu, de- 
scribed as above mentioned, where the whole of the 
mantle and scapulars are stated to be of a “ fine cine- 
reous grey,” like that of the Herring and most of the 
lighter-coloured Gulls.
