Out of this list seven species, to the names of which an asterisk is prefixed, have, as far as I know, not been before recorded as occurring in Sumatra. In addition to the above-named species are three which appear to be new, viz.:- DICRURUS SUMATRANUS, sp. n. This species seems to find its nearest ally in Dicrurus bimaensis, Wallace1, from Lombock, Sumbawa, and Flores. It, however, differs in having the plumage of the back pure black, without any metallic gloss. It also resembles that species in the form of the feathers springing from the base of the maxilla and covering the nostrils ; but in the present bird these feathers are much lengthened, reaching over nearly two thirds of the length of the bill. The rictal bristles are also much exaggerated, projecting nearly as far as the point of the bill. The Sumatran bird is also larger than D. bimaensis, having a wing of 5*9 inches length against 5*5 in British- Museum examples of the latter species (Wallace gives 5*25, I.e.). The tail is nearly square, one specimen only exhibiting a slight tendency in the outer tail-feathers to curl at the tip. The collection contains ten specimens of this Drongo, collected at Ayer-angat, Paio, and Mount Sago. Iris vermilion (Bock). TuRDINUS MARMORATUS, Sp. n. Reddish chocolate-brown, brightest on the flanks and belly, the feathers of the head and back margined with black, giving those parts a scale-like appearance. Beneath, the chin and throat and upper breast white, each feather with a black terminal bar, which becomes wider towards the breast; the lower part of the breast and centre of abdomen as far as the crissum black, with a terminal or subterminal bar of white across each feather; ear-coverts dark 1 P.
