Pharomacrus may readily be distinguished from Trogon by the development of the 
wing- and tail-coverts and by the feathers of the crown being more or less drawn 
together from either side so as to form a crest. These characters are all of them most 
distinctly shown in the Central-American representative of the genus, P. mocinno, in 
which two of the upper tail-coverts are often four times as long as the tail itself, and 
the wing-coverts curve over the primaries. 
Mr. Grant unites Gould’s Pharomacrus fulgidus to P. antisiensis of d’Orbigny, and 
recognizes four species of Pharomacrus, of which P. mocinno alone is found in our 
region—the other three being of South-American domicile, ranging along the Andes 
from Venezuela and Colombia to Bolivia. No species of the genus has as yet been 
found in the upland forests of Guiana or in Eastern Brazil.
