multifasciata: Upper lip narrowly but not conspicuously margined with white, 

 posterior surfaces of thighs without white spots. 



It is beyond the scope of this paper to draw up detailed synonymies 

 of each of these forms, but it seems that albopunctata Spix and 

 oxyrhina Reinhardt and Lutken are snyonyms of boans and that 

 microcentra Werner is a synonym of lancijormis. 



We give the reasons for using boans Latrielle rather than albo- 

 punctata Spix as the name for the southern form (see Cochran, 1955; 

 Rivero, 1961) in our discussion of the application of the name Hyla 

 maxima Lauren ti. 



When Rivero (1961) studied the Venezuelan forms he felt that 

 boans and multifasciata were close enough to justify calling them races 

 of a single species. It may be that all three forms are simply geo- 

 graphic races of a single wide-ranging species, but before we make a 

 taxonomic change we prefer to see material from more Amazon 

 Valley localities than are represented in the material presently 

 available to us.

2. CREPITANS group 



This group has only one representative in Colombia, and perhaps 

 in all of South America. It is characterized by a rather large size, by 

 the absence of a dermal heel appendage and of reticulations on the 

 palpebral membranes, and by having at least the two terminal phalan- 

 ges of the outer two fingers free of web.
