. A history of British birds. Birds. 450 BRITISH BIRDS. barsj and nearly all from the underparts^ leaving the colour greyish white; the conspicuous pale tips to the secondaries and some of the primaries have generally entirely disappeared; the lower wing-bar and the pale edges to the innermost secondaries have become very narrow; and traces only of the upper wing-bar are left. The autumn plumage is similar to that of springs but more brilliant^ the eye-stripes and the wing-bars yellower, and the upper parts a yellower green; the mesial line on the crown remains as obscure, and the underparts scarcely yellower. In winter the same amount of abrasion takes place as in summer; but the upper parts do not become so grey, and the eye-stripe and wing-bars retain a trace of yellow. The Yellow-browed Warbler has several near allies. Two of these, which breed in the Himalayas, P. erochroa and P. maculipennis, may be at once distinguished by having the inner web of the two outside tail-feathers on each side pure white. A third, P. proreguliis, breeding in the Himalayas and in the subalpine districts of South-eastern Siberia, differs from its northern representative in having a bright yellow rump. Two other species, P. subviridis and P. Jtumii, also breeding in the Himalayas, but ranging westwards, the one into Gilgit, north of Cashmere, and the other into Turkestan, are more difficult to discriminate. They may generally be told by their wing-formula, the second primary being usually intermediate in length between the eighth and the ninth, whilst in the Yellow-browed Warbler it is usually between the sixth and seventh. Fresh-moulted examples of P. humii may be discriminated by their buff' eye-stripe, of P. subviridis by the much yellower green of its upper and the greener tint of its underparts, and of both by their obscure upper wing-bar..
