THE YELLOW-LEGGED HERRING GULL.

Length, 23.0 to 25.75; expanse, 58 to 60; wing, 16.75 to 18 ; tarsus, 2.5 to 2.78 ; bill at front, 1.9 to 2.35.

Bill yellow, red at tip beneath in summer; in winter it is dull, yellow, whitish at tip, with a dark spot on both mandibles near the tip and an orange spot at the tip of the lower one. :- Stray Feathers, Vol. I, p. 270.

Summer plumage. :- Entire head, neck all round, entire lower parts, upper tail-coverts and tail pure white ; entire mantle and back, tertiaries and secondaries, a delicate pale bluish-grey ; the tertiaries and secondaries, and longer scapulars broadly tipped with white ; the earlier secondaries, especially with the major portion of the inner webs, also white ; edge of the wing about the carpal joint white ; primaries :- the first with the whole outer web black :- tipped with white and with a broad white band across both webs near the tip; above this band a considerable portion of the inner web is black, and the rest pale grey ; second primary similar, but the white band often entirely wanting or reduced to a spot on the inner web only ; the black on the inner web of less extent than in the first, and the basal portion of the outer web the same pale blue-grey as the coverts and the rest of the wing ; the third and following primaries have only the white tips and no white band, the outer webs become more grey as they recede from the second, and the black diminishes on the inner webs proportionally, so that on the seventh or eighth it is generally reduced to a narrow black band across both webs, or in some cases on the outer web only, and in others entirely wanting on the last three quills.

In the winter plumage the nape and the back of the neck are striated with pale brown, in some specimens thinly on the crown also; legs and feet lemon yellow.

This Gull is numerous during the winter in the Kurrachee Harbour and along the adjacent coast.
