Though Wagler’s description of the colouring of the base of the maxilla of his 
Pteroglossus pavoninus makes it almost certain that that name and Lichtenstein’s 
P. prasinus were applied to the same species, if not to the same specimen, we do 
not think it at all desirable to supercede the specific name prasinus for the older title 
pavoninus. The latter has been frequently used for the allied Aulacorhamphus waglert ; 
and, moreover, if Sturm’s statement, as quoted by Gould, is correct, that the 
inappropriate name “ pavoninus” was suggested.,by extraneous feathers inserted in the 
skin, additional justification for rejecting the title-i -is afforded. 
We adhere, therefore, to the practice which! has prevailed till now of calling this 
Toucan Aulacorhamphus prasinus. 
This species is common in all the upland forests of Eastern Mexico from the slopes 
of the Cofre de Perote southwards. It also occurs in the western district of British 
Honduras, where the mountains attain an elevation of upwards of 2000 feet. In 
Guatemala it is common in Alta Vera Paz and in the forest belt of the Volcan de 
Fuego. In the latter locality its loud call was familiar to us during our rambles in 
those attractive regions. Southwards of Guatemala it is doubtless found in suitable 
districts till we come to the mountains of Matagalpa in Northern Nicaragua, and here 
probably it stops, as in Costa Rica its place is taken by A. ceruleogularis. 
There is little to be said respecting the habits of this species; birds are rather 
solitary and silent when observed, and keep in the upper branches of the higher trees. 
We have no notes on its nesting peculiarities.
