* The extremity of thAlippér mandible of the beak, which is some- 
what more elongated and compressed, is curved downwards. The 
large head, short tail and great beak of these birds give them a stupid . 
appearance. All the known species are from America, and live on 
insects. Their natural disposition is sad and solitary.(2) 
Trogon, Lin.(3) 
The Couroucoui, along with the hairy fasciculi of the Barbets, ave 
a short beak, which is more broad than high, and curved from the 
base, its upper ridge arcuated and blunt. Their small feet, feathered 
nearly down to the toes, long broad tail, fine light and dense plu- 
mage, give them quite a different air. Some part of their plumage 
usually has a metallic lustre, the remainder being coloured more or 
less vividly. They build in hollow trees, live on insects, and remain 
in a solitary and quiet mood on low branches in the centre of marshy 
forests, never being seen on the wing except during the morning 
and evening. They are found in both continents. 
The edges of the mandibles, in the American species, are 
dentated.(4) In those of the eastern world, they are more 
entire.(5)
