Tre discovery of a new Bird of Paradise must always be a matter of interest to naturalists, and especially
when the species proves to be of so fine a character as the present bird. The home of Paradisea decora is
Fergusson Island, in the D’Entrecasteaux group, whence comes the beautiful Manucodia comri, also figured
by us in the * Birds of New Guinea.’

We owe the discovery of this beautiful bird to Mr. A. Goldie, to whose energies science has been indebted
for many years. He has given the following account of its capture :—

“The Birds of Paradise were shot on Fergusson Island, one of the D’Entrecasteaux group, in the
mountains, at a considerable elevation above the sea, the first specimen obtained having been secured at the
lowest point. The plumed males and the younger individuals were generally seen three or four together.
Once heard, their call was unmistakable, being very like that of Paradisea ragegiana ; but the plumed and
wired birds, after giving that calla few times, added to it a peculiar shrill whistle. Their motions whilst
calling were identical with those of P. raggiana ; but, so far as we were able to observe, they had no particular
tree for dancing in. The females were found alone.

** We neither saw nor heard P. raggiana on these islands ; and the new bird is not found on the mainland.
On showing it to the natives of Chad’s Bay and China Straits along with a specimen of Paradisea raggiana,
they, in both cases, made us to understand that the latter is found in their country, whilst the former is not;
but two or three of them in China Straits who had traded to the D’Entrecasteaux Islands made signs that
the new bird was to be found there.”

The nearest ally of the present species is P. raggiana, and, like that bird, it has red flank-plumes ; but it
differs in its yellow back and grey chest, the latter extending up to the green throat, and not being separated
from it by a yellow collar.

The description of the species, as given by Messrs. Salvin and Godman, is so complete that we transcribe
it entire. We may add that the typical series, described by them, is now in the British Museum.

“‘ Fergusson Island was so named by Capt. Moresby, who calculated that the mountain called Kilkerran
(the highest near the northern coast) reaches an altitude of 6000 feet above the sea. wo other large
islands, Goodenough Island and Normandy Island, lie close to Fergusson Island, and form the chief islands
of the group.

“ Paradisea decora, as we have proposed to call this Bird of Paradise, combines the characters of some
of the previously known species. The side-plumes are like those of P. sanguinea, each feather having its
barbs towards the end wide apart and destitute of barbules. These feathers are similarly formed in
P. sanguinea ; but in the present bird the barbs are even wider apart. The‘ wires’ of the tail are like those
of P. apoda, P. minor, and P. raggiana, the feathers having a simple stem on which the atrophied barbs
become more and more evanescent till they disappear at the middle of the feather to reappear again at its
extremity. In P. sanguinea the stem is broad and flattened.

“The side-plumes of P. decora are very peculiar, inasmuch as a number of the anterior plumes are
quite short, in the barbs of each feather much lengthened towards the end; the distal ends of these
feathers are deep rich vinous red, and appear as if the pigment which colours the elongated plumes were
concentrated in these shorter ones. .

«The breast of P. decora is of a soft vinaceous lilac, and in this respect differs from that of all its congeners.
The throat is velvet-green, showing two shades, owing to the feathers HORE the chin nefleenng, the light at
a different angle. This darker-looking patch is larger in P. decora tbe in the other species. The back,
except the narrow green forehead, is straw-coloured, like that of P. a

‘*Mr. Goldie’s series contains males in all stages of development. The youngest are like the females, but
with the throat green; the breast is of a ruddy tint, vermiculated with ey marks on each feather. : . the
