specimens (see Fig. 18). We are not the first to notice this, for the 

 late E. R. Dunn made a handwritten note on a manuscript key to 

 Gastrotheca, under arqenteovirens, that the San Pedro form might be 

 new. 



Remarks. — Since the correct assignment of the name "argenteovirens" 

 has been a problem, we sent two of the large series of specimens from 

 Nariiio (CNHM 54823, a male, and 54824, a female) to our good 

 friend Dr. Robert Mertens in Frankfurt and asked him to compare 

 them with the type. He wrote that both he and his colleague, Dr. 

 Klemmer, had made the comparison and both were of the opinion 

 that the two specimens were conspecific with the type. For this we 

 are very grateful.

Genus Hyla Laurenti 



1768. Hyla Laurenti, p. 32 (type species, Hyla viridis Laurenti). 



Diagnosis.- — Without teeth on mandible, palatine, or parasphenoid; 

 vocal pouch in male, if present, median and subgular; pupil horizontal; 

 sacral diapophysis well expanded in all except some of the larger 

 forms; cranial derm not fused with skull except in a few West Indian 

 species; neither eggs nor young carried on back of female; tympanum 

 present and usually fairly distinct, tongue fairly well fused behind; 

 a well-developed quadratojugal; no backward projecting process on 

 ischium; no well-developed ventrolateral gland along each side. 



Remarks. — Following the method used by the senior author in 

 her Frogs oj Southeastern Brazil (Cochran, 1955) we have divided 

 the large, unwieldy genus Hyla into several groups. In many cases 

 these groups coincide with those that the senior author recognized 

 in southeastern Brazil. In other cases the groups here recognized 

 differ either in generally being less inclusive or in not being recognized 

 as groups in the Brazilian work. In the former case, the difference 

 is most often due to the fact that with more material available we 

 have been able to further subdivide some of the earlier, larger groups. 

 In the second case the difference may be due either to the fact that 

 we here recognize groups heretofore not recognized or groups that 

 are not represented in southeastern Brazil.
