character, however, is not well defined, and is carried to nothing like the extent seen 
in Campylopterus. 
Two species constitute the genus, one of them belonging to Eastern Guatemala and 
thence southward to Nicaragua, the other to Costa Rica, Panama, and probably the 
north-western corner of South America.

This species was discovered by Delattre and described by him and Bourcier in 1846 
from specimens said to have been shot on the Isthmus of Panama and at 'Teleman. If 
the latter place is the village of that name on the banks of the Polochic river in 
Guatemala, both P. cuviert and P. roberti were included in Delattre’s collection. The 
description undoubtedly refers to the Panama bird, as the colour of the base of the 
mandible is given as white, that of P. roberti being wholly black. 
The range of this species, as given by Gould, extends to Colombia and Venezuela, 
but we have never seen specimens from any place south of the line of the Panama 
Railway. Northwards and westwards of this line it spreads over the rest of the State 
of Panama to Western Costa Rica, where it is not uncommon on the shores of the Gulf 
of Nicoya. In Nicaragua, and thence northwards to British Honduras, its place is 
taken by P. robert.
