Hah. South America from Colombia down to Bolivia and S. Brazil. 



Specimens of Procnias, except those from S.E. Brazil, seem rather 

 referable to the smaller subspecies, occidentalis. But some of them 

 are certainly intermediate in size ; I therefore now quite agree 

 with Messrs. Salvin and Godman (Ibis, 1879, p. 199) that the 

 smaller form is untenable as a species, the difference being solely 

 one of dimensions, in which also there is considerable variation.
