Like the other members of the genus, this large and powerful species of Pharomacrus appears to be strictly 
a dweller among mountainous districts, and to be especially abundant in the neighbourhood of Santa Fe de 
Bogota, great numbers being comprised in every large collection of birds sent from that city; I also possess a 
single specimen which was transmitted to me direct from Quito by Professor Jameson; it is probable, there¬ 
fore, that it may hereafter be found to inhabit all the intermediate countries between these two somewhat 
distant localities. Like the P. Pavoninus, this species has a black tail; but it differs from that bird in many 
other respects, especially in its much greater size and in the bright yellow colouring of its bill, which organ 
is blood-red in P. Pavoninus. Dr. Percy has called my attention to an interesting article on the colouring 
matter of this species by M. An. Bogdanow, of Moscow, in the “ Comptes Rendus,” tom. xlv., Nov. 1857 ; 
but as these observations are more fitted for the Introduction, they are omitted here. 
I am not quite certain whether the bird represented by the back figure in the accompanying Plate is a 
young male or a female, but I believe it to he the former; still, to distinguish the young males from the 
females with certainty, it will be necessary to resort to actual dissection. 
The figures are of the natural size.
