520 MESSRS. SCLATER AND SALVIN ON THE CRACID&. [June 9, 
Buffon assigns Cayenne as the habitat of this Curassow; but 
Schomburgk does not mention it as found in British Guiana. A 
more certain locality is the Rio Cassiquiari and Upper Orinoco, 
where Natterer, although he did not collect specimens, obtained 
certain evidence of its existence (Cf. Von Pelzeln, Orn. Bras. p. 289). 
Specimens of this bird in the Paris Museum were transmitted from 
Caraccas by M. Levraud. Tschudi states that it occurs in Eastern 
Peru. This is possible, but we have never seen it in collections 
from the Upper Amazon*,

* Since this paper was written, the Society have received two living males of 
this species direct from Santa Martha along with a female of Crax alterti. It 
is probable, therefore, that Pawat galeata is likewise found in the valley of the 
Magdalena.
