Genus SELENIDERA.

CHARACTERES GENERICI.

Rostrum brevius et crassius quam in genere Pteroglosso, nec non cauda brevior est ratione ad magnitudinem corporis
habita ; inter sexus color differt, mare caput pectusque nigra habente ; his partibus foemind castaneis ; plume auri-
culares flave ; lunulaque flava cervicem imum cingit. Ad hane notam titula generica refert.

PTEROGLOSSUS (Selenidera) GOULDII.

Ptero. summo capite, nucha, gutture, pectore, abdomineque nigris ; plumis auricularibus aurantiaco-flavis ad apicem strami-
neis ; fascia semilunari nuchali flava ; dorso, alis, cauddque olivaceo-fuscis ; hujus rectricibus sex intermedits apice
castaneo ; lateribus aurantiaco-flavis ; femoribus castaneis, crisso coccineo, cute circa oculos viridi ; rostri mandibuld
superiore nigra, apicem versus livide corned, apice albo, fascidque angustd alba ad basin ; mandibuld inferiore alba
fascia nigra, apiceque vide corneo, pedibus plumbeis.

Femina differt partibus, que, in mare nigra, in illd castaneis, et lateribus plumisque auricularibus pallidioribus.

Long. tot. 11 une. ; rostri, 21; ale, 5; caude, 42; tarsi, 1+.

Mate. Crown of the head, back of the neck, throat, chest, and centre of the abdomen jet black; ear-coverts
orange yellow, passing into fine straw yellow at the apex; across the top of the back a semilunar mark of
pale yellow; back, wings, and tail dark olive, the six centre feathers of the latter tipped with chestnut brown ;
flanks deep orange yellow; thighs chestnut; under tail-coverts scarlet, bare space round the eye green ;
upper mandible black, passing into greenish horn colour towards the tip ; the latter and a narrow line
surrounding the base white; under mandible white for three-fourths of its length from the base ; an irregular
band of black separates this from the tip which is white with a tinge of olive; feet lead colour.

Femate. Differs from the male in having all those parts which are black in that sex of a fine chestnut; and in
the flanks and ear-coverts being of a paler tint.

Pteroglossus Gouldu, Natt. in Proc. of Zool. Soc. Part V. 1837.

 

Turs species of Aragari having been made known to science since the completion of my Monograph of ce
Family, I take this opportunity of publishing figures of both sexes from specimens presented to the Zoological
Society of London by M. Natterer, who procured them in the Brazils on the banks of the River Madeira, ae
who has been pleased to name them after myself at a meeting of the above Society on the Hoa of eye 1837.
In its affinity the Preroglossus Gouldit is very nearly allied to the TOA, maculirostris, but differs from
that species in being considerably less in all its proportions, in the single large patch of black on the upper
mandible (which in Ptero. maculirostris is regularly marked with transverse oval-shaped spots), oe in the
more intense orange colouring of the sides of the body: I may add that these differences are found to be
constant in the several examples of this species contained in M. Natterer’s collection.

In the Introduction to my Monograph of this interesting group, the members of the family are thrown “we
sections, and I am now inclined to add to the best marked of these sections a generic, or at ace a subpenetie
name. The genus Aulacorhynchus having been very generally adopted, L take this opportunity of making a
further subdivision of the family by separating from the true Pteroglossi (of which Piero. Gas ane Ptero.

) pluricinctus are typical examples, ) the following species, Viz. Ltr es Gould, Ne maculirostris, ee.
Nattereri, Ptero. Reinwardsu, Piero. Lang sdorffii, and Ptero. Culthe, under the generic name of Selenidera.
The members of this minor group differ not only in the modifications ee Se bat are adorned with
a different style of plumage, the sexes offering a decided contrast in their colouring, which is not the case with
rue Pterogloss?.
oe are panauisted by yellow ear-coverts, and a lunar-shaped band of the ae: ee a ne ae
part of the neck, to which latter peculiarity our subgeneric title alludes. The ma Ge so has the head, :
and centre of the abdomen black, while the same parts in the female are chestnut brown.

The Plate represents a male and female of the natural size.
