2867 ♂
Sp. Char. Upper surface generally, with the head and neck all round to the upper part of the breast, deep black; the rest of lower parts pure white, except the sides of the body and under tail-coverts, which are light chestnut-brown; the latter rather paler. The outer webs of scapulars (usually edged narrowly with black) and of the superincumbent feathers of the back, with a rounded white spot at the end of the outer webs of the greater and middle coverts; the outer edges of the innermost tertials white; no white at the base of the primaries. Outer web of the first tail-feather black, occasionally white on the extreme edge; the outer three with a white tip to the inner web. Outer quill shorter than ninth, or scarcely equalling the secondaries; fourth quill longest; fifth scarcely shorter. Length, 8.25; wing, 4.40; tail, 4.00.
