The bright green Toucans which form the genus Avlacorhamphu.'s 

 are at once recognizable by theu- uniform style of plumage, wliich 

 imitates that of the forest-leaves. They are rather numerous in 

 species and are widely distributed in the Neotropical Region, two 

 of them being met with in Mexico, and others taking their places 

 throughout Central and Southern America into the south of 

 Amazonia, but not extending to the forests of S.E. Brazil. 



The sexes in this genus are coloured alike.
