On the 28th of June 1859, in the absence of Mr. G. R. Gray from London, I exhibited to the meeting 
of the Zoological Society, held in the evening of that day, some specimens of both sexes of this singular bird 
which had just arrived, and took the opportunity of remarking that, while I considered Mr, Gray right in 
viving it a new generic appellation, the family to which Mr. Wallace had assigned it was not, in my opinion, 
the right one, This beautiful bird is not indeed a Bird of Paradise if we regard the Paradisea apoda and 
P. Papuana as typical examples of that group; it is in fact very closely allied to Ptiloris, so nearly so, 
indeed, as scarcely to be separable from that form; for on comparing it with the well-known Rifle-bird of 
Australia, Ptiloris paradisea, it will be seen that they are very similar both in their structure and in the 
disposition of their markings: the same great difference in the outward appearance of the sexes also occurs 
in both. Second only in interest to the discovery of this bird, would be an account of its habits and 
manners; and I trust Mr. Wallace will ere long enlighten us on these points. In the absence of this 
information, I would venture an opinion that it 1s partially a creeper in its habits; but whether it frequents 
the boles of the larger trees or the faces of rocky precipices is uncertain; neither do we know in what way 
the males display the plumes which spring out at right angles from the outer part of the shoulder: that the 
bird has the power of erecting and depressing them at will is without doubt. In the female they are entirely 
absent. 
The male may be thus described :— 
“On the basal half of the upper mandible a series of erected tuft-like feathers of a pale sandy buff, blend- 
ing on the forehead into the delicate velvety dove-coloured feathers of the crown and occiput; sides of the 
head, back of the neck, and upper surface light brown, becoming darker and having a velyety appearance on 
the back and scapularies; each of these feathers has also a very narrow edging of a lighter hue; wings 
light brown, fading into buffy white, with a silvery gloss at the tips of the primaries and secondaries ; shafts 
of the primaries white ; the two lengthened plumes springing from each shoulder snowy white; tail brown 
with white shafts, and becoming of a silvery light brown at the tip; throat, neck, chest, and projecting side- 
plumes fine emerald-green, becoming very brilliant on the tips of the plumes; under surface brown, the 
feathers of the breast bordered with brilliant green, giving it a scaled appearance ; flanks washed with the 
same colour, but less brilliant; thighs light brown; bill brownish horn-colour ; feet yellow. 
The female has the tuft on the upper mandible and the crown of the head the same as in the male, and is 
entirely devoid of the green colouring and lengthened plumes both of the breast and wings, her entire plu- 
mage being brown, without ornamentation of any kind. 
The Plate represents one male of the natural size, and a second male and a female considerably reduced.
