Coloration. Male. In the summer the whole plumage is black, except the lower part of the rump, the upper and lower tail-coverts, and those feathers of the wing nearest the body, which are white, the latter forming a very conspicuous patch on the wing.
In the autumn the black feathers are more or less fringed with rufous-brown.
of these, but to which will probably never be satisfactorily determined, Linnaeus assigned the name Motacilla sybilla (Syst. Nat. i, p. 337). I propose, therefore, that Linnows's name should be retained for the smaller bird, with wing 25 or 2'G, and Tristram's name for the larger, with wing 2'9. The occurrence of P. robusta in India must, for the present I think, be viewed with a certain amount of distrust, and I therefore omit it from my list. The following is a description of the type, which appears to be a male, judging from its fine colour: The breast and sides of the body are a deep cinnamon-rufous, sharply de- marcated from the pure white of the abdomen, which extends to the vent and under tail-covert:* ; the axillaries and under wing-coverts are white with dark bases ; the tail is black ; the other parts of the plumage resemble the same parts in P. maura and P. leucura in autumn plumage. Length ah >ut <> ; tail 24 ; wing 29 ; tarsus '9 ; bill from gape '6. The many specimens from the Himalayas which have been identified with this species by Brooks, Scully, and others are quite a different type of bird and are, in my opinion, merely large specimens of P. maura.
