Genus SELENIDERA.
C h a r a c t e r e s G e n e r i c i .
Rostrum brevius et crassius quchn in genere Pteroglosso, nec non cauda brevior est ratione ad magnitudinem corporis
habitd; inter sexus color differt, mare caput pectusque nigra habente; his partibus fcemind castaneis; phima auricular
esflava ; lunulaque flava cermcem imum cingit. Ad hanc notam titula generica refert.

Long. tot. 11 unc. ; rostri, 2-J-; ala, 5 ; cauda, 4-f-; tarsi, 1-g-.
M a l e . Crown of the head, back of the neck, throat, chest, and centre of the abdomen je t b lack; ear-coverts
orange yellow, passing into fine straw yellow a t the’ apex; across the top of the back a semilunar m ark 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.
F e m a l e . 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 Gouldii, Natt. in Proc. of Zool. Soc. Part V. 1837.
T h i s species o f Arapari having been made known to science since the completion o f my Monograph o f the
Family, I take this opportunity o f publishing figures o f both sexes from specimens presented to the Zoological
Society o f London by M. Natterer, who procured them in the Brazils on the banks o f the River Madeira, and
who has been pleased to name them after myself a t a meeting o f the above Society on the 11th o f April 1837.
In its affinity the Pteroglossus Gouldii is very nearly allied to the Pteroglossus maculirostris, but differs from
th at species in being considerably less in all its proportions, in the single large patch o f black on the upper
mandible (which in Ptero. maculirostris is regularly marked with transverse oval-shaped spots), and in the
more intense orange colouring o f the sides o f the body: I may add that these differences are found to be
constant in the several examples o f this species contained in M. Natterer’s collection.
In the Introduction to my Monograph o f this interesting group,-the members o f the family are thrown into
sections, and I am now inclined to add to the best marked o f these sections a generic, o r a t least a subgeneric
name. The genus Aulacorhynchus having been very generally adopted, I take this opportunity o f making a
further subdivision o f the family by separating from the true Pteroglossi (o f which Ptero. aragari and Ptero.
pluricinctus are typical examples,) the following species, viz. Pteroglossus Gouldii, Ptero. maculirostris, Ptero.
Nattereri, Ptero. Reinwardsii, Ptero. Langsdorjjii, and Ptero. Culik, under the generic name o f Selenidera.
The members o f this minor group differ not only in the modifications o f their structure, but are adorned with
a different style o f plumage, the sexes offering a decided contrast in their colouring, which is not the case with
the true Pteroglossi.
They are distinguished by yellow ear-coverts, and a lunar-shaped band o f the same colour across the lower
p a rt o f the neck, to which latter peculiarity our subgeneric title alludes. The male also has the head, chest,
and centre o f the abdomen black, while the same parts in the female are chestnut brown.
The Plate represents a male and female o f the natural size.
