It is certain that the Guian an form of this group is F. nigrifrons, 

 but it appears to be the present species that is figured in the 

 'Planches Enluminees' as " Le Tetema de Cayenne." To avoid 

 confusion I have, consequently, adopted Gmelin's specific term in- 

 stead of Boddaert's, which indicates a wrong locality.
