[[p. 474]] I have here given the characters of twenty-one species of birds which appear to be new, and which, together with those already described by Mr. G. R. Gray and myself in the 'Proceedings' of this Society, and also a few described by Mr. Gould and Dr. Sclater, make up the number of 212 new species collected by me in the islands of the Malay archipelago. Of those now described, eight are from Celebes, and the rest from Sumatra, Borneo, the Moluccas, and the New Guinea group.

    ACCIPITER ÆQUATORIALIS.

    Supra cinereo-plumbeus, subtus cum torque humerali rufo-castaneus; capitis lateribus cinereis, gula pallide rufo-cinerea, cauda alisque immaculatis.

    Above slaty ash-colour; beneath light chocolate-brown, which extends in a broad collar between the shoulders; sides of the head ash-colour; throat light ashy, tinged with rufous; wing and tail uniform light ash-colour beneath; under wing- and tail-coverts scarcely paler than the belly; bill and claws black; cere, eyelids, and legs orange-yellow; iris golden orange-yellow.

    ♂. Total length 14 1/2 inches; wing 7 3/4; tail 6; tarsus 2; bill, to gape, 11/12.
    ♀. Total length 16 1/2 inches; wing 9; tail 7 1/2; tarsus 2 5/8; bill, to gape, 1 2/12.
    Hab. Batchian, Gilolo, Morty Islands, Waigiou, and Salwatty.
    Remarks.--This species was pointed out to me by Mr. Gurney as being near A. rufitorques, Peale, which inhabits the Feejee Islands. It differs from that species in its rather larger size, different proportions, and coloration. It is also near A. griseogularis, G. R. G., which inhabits the same district; but differs from that species by its much smaller size, and in the entire absence of bands on the body, wings, or tail in the adult birds. Both these seem to be included

[[p. 475]] by Prof. Schlegel, in the 'Muséum des Pays-Bas' (Astures, p. 41), as forms of A. cruentus, Gould, which is confined to Australia and the adjacent island of Timor.

    ACCIPITER MUELLERI.

    Supra fusco-plumbeus, subtus rufo-cinnamomeus, capite plumbeo, gula albo-rufescente, cauda tenuiter fasciata.

    Very like Accipiter hiogaster, Müller, but much larger, the throat less distinctly rufous, the under parts faintly white-banded, and the tail with about ten narrow bands; bill black; cere and feet bright yellow. The comparative dimensions of the two species will best show the difference between them.

    GERYGONE NEGLECTA.

    Viridi-olivacea, subtus alba flavo tincta; remigibus rectricibusque fuscis flavo-viridi marginatis, rostro pedibusque pallidis.

    Above rich greenish olive; beneath white, tinged with yellow, deepest on the belly; under wing-coverts white; quills and wing-coverts dusky, margined with olive-yellow; tail dusky, the feathers more obscurely margined; bill dusky; lower mandible very pale; feet pale.

    Total length 4 1/3 inches; wing 2 1/8; bill, to gape, 1/2.
    Hab. Waigiou; Mysol.
    Remarks.--This species is most like G. chloronota, Gould. It is rather abundant in the island of Waigiou, frequenting thickets and bushes, catching insects on the wing, or picking them from the bark, and may often be heard snapping its bill like the larger true Flycatchers.

    GERYGONE PALPEBROSA.

    Supra olivaceo-viridis, subtus flava; gula alba, loris et tectricibus aurium albo-cinereis, palpebris nigris; remigibus rectricibusque fuscis flavo-viridi marginatis.

    Above olive-yellow; beneath bright yellow; band across the rump, eyelids, and space before the eye yellow; wing and tail dusky, with the feathers yellow-margined; bill black above, beneath and feet dusky orange; claws pale; iris dark.

    Total length 4 3/4 inches; wing 2 3/10; tail 2; bill, to gape, 1/2.
    Hab. Menado (Celebes).

     RHIPIDURA LONGICAUDA.

    Fusca; capite, mento, fascia gulari, lateribus pectoris caudaque fusco-nigris; gula, pectore et superciliis albis; ventre ochraceo-albo; alis fusco-nigris, tectricibus alarum rufo terminatis; cauda longa, rectricum extimarum utrinque trium apicibus albis.

    Very near Rhipidura javanica, from which it differs in the longer tail, narrower white tips to only three outer tail-feathers, and the black chin; iris dark; bill and feet black.

    Total length 7 1/4 inches; wings 3 1/8; tail 4 (R. javanica, 3 1/2 inches).
    Hab. Sumatra.

    Olive-brown; beneath white; vent and under tail-coverts rufous-tinged; in front of and beneath the eye, ear-coverts, lower part of the neck, and breast black; on the lower parts each feather is white-edged; forehead and a short stripe above the eye, lower part of the back, upper tail-coverts, and half the tail (less on the outer feathers) rust-red; lower eyelid white; all the tail-feathers, decreasing to the middle ones, white-tipped; bill dusky, very short, bristles from gape very long; feet dusky olive; iris dark.

    Total length 6 1/2 inches; wing 3; tail 3 1/3.
    Hab. Ternate, on the summit of the volcano, 4000 feet above the sea.
    Remarks.--Near R. semicollaris, Müll., from Banda, from which it differs in the shorter bill, as well as in the arrangement of the colours.

    RHIPIDURA CINEREA.

    Fusco-cinerea; alis caudaque fuscis; subtus alba, pectore cinereo albo maculato.

    Dusky ash-colour; head rather darker; wings dusky brown; tail rather darker; over the eye a nearly concealed white stripe; neck and throat white; breast and sides ash-colour, feathers on upper part of the breast with each a white oval spot; middle of the lower breast, belly, under tail- and wing-coverts white; bill black, large and strong; feet dusky.

    Total length 6 3/4 inches; wing 3 1/3; tail 3 1/3.
    Hab. Ceram.
    Remark.--Nearest to R. assimilis, G. R. Gray, from which it may be at once distinguished by its want of any terminal white spots on the tail-feathers.

    PRIONOCHILUS AUREOLIMBATUS. (Pl. XXIX. fig. 1.)

    Fulvo-olivaceus, alis caudaque nigris; fascia a fronte ad aures fusco-nigra; subtus albus, pectore grisescente, lateribus corporis tectricibusque caudæ inferioribus luteis.

    Hab. Banda Islands and Salwatty.
    Remark.--The Banda specimen is rather lighter-coloured on the sides of the head, and the brown of the back is a little brighter, but in other respects it exactly agrees with that from Salwatty.

    DICRURUS LEUCOPS.

    Irides albæ; D. pectorali paulo major.

    Exactly like D. pectoralis, Wall., in coloration, except the irides, which are milk-white. As every other species of the genus I have met with has eyes of a crimson-red colour, and as I found this species abundantly both at Macassar in the south and at Menado in the north of Celebes, and in every individual having the eyes milky white, I think it right to separate it under a distinct name. It is, however, rather larger in all its dimensions than the allied form.

    Total length 12 1/4 inches; wing 6 1/4; tail 5 1/2; bill, from gape, 1/43.
    Hab. Celebes.

    PTILOTIS ROSTRATA.

    Ptilotis megarhynchus, G. R. Gray, Proc. Zool. Soc. 1859, p. 155.

    Dark brown; crown dusky; beneath ashy olive; belly rufescent; under wing-coverts and inner margins of the quills light rufous; bill black, long, and strongly serrated at the end of the upper mandible; iris salmon-red; feet pale lead-colour.

    Total length 9 1/4 inches; wing 3 3/4; bill, from gape, 1 2/3.
    Hab. New Guinea, Waigiou, and Mysol.
    Remark.--This differs from P. megarhynchus, G. R. Gray, from Aru, in the want of the yellow ring round the eye and the markings of the under surface, as well as in the remarkably serrated bill.

    NECTARINIA FLAVO-STRIATA. (Pl. XXIX. fig. 2.)

    Fronte et vertice cæruleo-metallicis; occipite, collo et dorso rubris, uropygio flavo, tectricibus superioribus et rectricibus mediis cæruleo-metallicis, rectricibus lateralibus nigris cæruleo marginatis; alis fuscis, remigum et tectricum marginibus luride rubris, gula (utrinque cæruleo vittata) et pectore coccineis flavo [[p. 479]] striatis; partibus inferioribus fusco-olivaceis, tectricibus alarum inferioribus albis.

    Very near N. siparaja, Raffl., from which it differs by the yellow-striped throat, the red-margined quills, the blue instead of violet tail-coverts, the darker under parts, and the shorter tail. The whole bird is also larger. Bill olive, reddish below; feet dusky.

    Total length 4 3/4 inches; wing 2 1/10; tail 1 3/4; bill, to front, 7/10.
    Hab. Menado (Celebes).

    Purple-black; crown golden green; bend of the wing, lesser wing-coverts, lower part of the back, upper tail-coverts, and outer edges of the tail-feathers steel-blue; throat changeable violet-purple, with a line from the gape on each side steel-blue.

    Total length 4 1/2 inches; wing 2 3/10; tail l 1/2; bill, from gape, 8/10.
    Hab. Macassar.

    NECTARINIA GRAYI.

    Purpureo-nigra; pileo aureo-viridi; nucha, dorso supremo et pectore purpureo-ferrugineis; dorso infimo, tectricibus alarum et caudæ superioribus cæruleo-æneis; jugulo violaceo-amethystino linea æneo-cærulea utrinque marginato.

    Purple-black; crown golden green; nape, back, and breast rich purplish rust-colour; rump, upper tail- and wing-coverts, and margins of the tail-feathers steel-blue; throat violet-red, margined on each side by a line from the gape of steel-blue.

    Hab. Menado.
    Remark.--Mr. G. R. Gray had proposed to name this richly coloured species after myself; but as he has left it hitherto undescribed, I have called it after him.

    MUNIA TRISTISSIMA.

    Total length 4 inches; wing 1 11/12; tail 1 1/2; bill, from front, 1/3.
    Hab. New Guinea (north-western extremity).
    Remark.--This is the first Finch that has been recorded from New Guinea, and its sombre plumage contrasts strongly with the many [[p. 480]] brilliant birds which inhabit the same great island, whose surface, clothed with perpetual forests, seems ill-adapted to this grass-loving group of birds.

    TURNIX RUFILATUS.

    Supra olivaceo-rufescens, tenuiter nigro undulato-fasciatus; plumis capitis et in medio dorsi nigro maculatis; fronte nigra, linea superciliari, facie et gula nigro et albo punctulatis; pectore et
