Though Wagler's description of the colouring of the base of the maxilla of his 

 Pteroglossus pavminus makes it almost certain that that name and Lich ten stein'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 prasiniis for the older title 

 pavoninus. The latter has been frequently used for the allied Aulacorhamphus wagleri ; 

 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 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. cceruleogularis. 



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.
