Pteroglossus Nattererii, Gould, Proceedings of Zool. Soc., Part III.
A lthough I have at all times endeavoured to avoid the imposing of a specific title on a new species which
did not convey some idea connected with its form or colouring, I have been induced to deviate from this rule
in the present instance from the earnest desire I feel to pay a just tribute of respect to a most enthusiastic
and able naturalist, through whose personal exertions in the Brazilian forests for the period of eighteen years
so vast a collection has been transmitted to the capital of that country by the munificence of whose Government
he was enabled to prosecute his researches; and I would here beg to offer my acknowledgements to
M. Schreibers, the highly talented director of the Imperial Museum of Vienna, for the liberal manner in which
he permitted me to examine the birds of this group contained in the collection under his care, and to add
to my monograph a representation of this rare species.
I am not aware of the precise locality in which this fine bird was obtained, but from the circumstance of
its having accompanied other specimens from that part of Brazil which borders the river Amazon, it may
reasonably be believed to be a native of the woods of those districts.
In point of affinity it is closely allied to the Pteroglossus maculatus, and with that bird and several others it
will form a separate and well-defined group, possessing many peculiar characters.
