This genus is usually, but wrongly, known as Hylodes. A genus of 

 this name was instituted by Fitzinger in 1826,^ based upon two species 

 onl}^ one of which must be the type. They were Tlyla (jTavenliorstli 

 Fitzinger and Ilyla rcmoides Spix. The former is a nomen nudum and 

 was never described, the generic term Hylodes being thus restricted 

 to //. rajwides. Regarding the word Hylodes as improperly formed, 

 Wagler, in 1880, substituted'' Enydrohius^ which consequently is a 

 synonym pure and simple. Tschudi, in 1838,'^ expressl}^ recognizes H. 

 ranoides as the type of Ilylodes^^ but at the same time he erected Elosia 

 for Lichtenstein's Ilyla 7iasus (or oiasuhis, as Tschudi writes), not 

 knowing that this species was identical with 11. ranoides., the tj^pe of 

 Hylodes. This error has been perpetuated by later writers, chiefly 

 led b}^ Dumeril and Bibron, and also possibly influenced by the fact 

 that Fitzinger himself, in 18-i3, followed the example of these authors 

 and substituted H. inartinicensis., which was not described until 1838, 

 as type for the genus established by himself in 1826. 



As to the proper name for the genus the choice lies between the one
