the three species of the genus Psophia, P. crepitans 
(Linn.), P. viridis (Spix), and P. leucoptera (Spix). The 
P. crepitans is the common trumpeter of Guiana ; it 
extends into the interior all over the country, beyond the 
sources of the Rio Negro and Orinooko, towards the 
Andes, and down to the Amazon, both east and west of 
the Rio Negro, but is never found on the south side of 
the Amazon. 
The P. viridis is found in the forests of Para, at Villa 
Nova, on the south bank of the Amazon, and up to the 
Madeira, where it is found at Borba, on the east bank. 
The P. leucoptera, a most beautiful white-backed spe- 
cies, is found also on the south bank of the Amazon, at 
Sao Paulo, at Ega, at Coari, and opposite the mouth of 
the Rio Negro, but not east of the Madeira, where the 
green-backed species commences. These birds are all 
great favourites in the houses of the Brazilians, and all 
three may sometimes be seen domesticated at Barra, 
where they are brought by the traders from the different 
districts in which they are found. They are inhabitants 
of the dense forests, and scarcely ever fly ; so that we see 
the reason why the rivers should so sharply divide the 
species, which, spreading towards each other from dif- 
ferent directions, might otherwise become intermingled. 
It is not improbable that, if the two Brazilian species 
extend as far as the sources of the Madeira, they may 
be found inhabiting the same district. 
Of the smaller perching-birds and insects, which 
doubtless would have afforded many interesting facts 
corroborative of those already mentioned, I have nothing 
to say, as my extensive collection of specimens from the
