rest of the wing, nearly dusky grey; the vent and 
under tail-coverts are white; the legs, toes and webs 
very dark reddish brown; the webs are much in- 
dented, and the toes project some way before them. 
The adult bird before mentioned as having been 
killed out of the flock at Burnham, in August, had 
the fore part of the head and the neck very much 
mottled with white; in the full plumage these parts 
are quite white. The young birds shot at the same 
time had the bill nearly black; the forehead, the 
space between the bill and the eye, the fore part and 
side of the neck, a collar at the back of the neck, the 
breast, flanks, belly and all the under parts are white ; 
the top of the head, nape and ear-coverts are black ; 
the back and scapulars immediately behind the white 
collar almost black, the rest smoky grey, each feather 
margined with pale brown, palest towards the tips; 
the rump and tail-coverts light grey; the wing dusky 
on the shoulder; both sets of wing-coverts smoky 
grey, more or less margined with brown and tipped 
with white; the primary quills dusky at the points, 
more inclining to grey towards the base; the second- 
aries are dark dusky grey; tertials the same, narrowly 
margined with white; tail-feathers darker grey than 
the coverts, narrowly edged at the tips with white. 
The eggs arc said to be of a dark greenish or red- 
dish olive, blotched and spotted with two shades of 
dark brown and very dark, nearly black: they are 
rather larger than those of the Lesser Tern.
