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.
