seems to be a species of the eastern slopes of the Andes, while punctata 

 is a species of the lowlands. The possibility exists that rhodoporus may- 

 represent a race of punctata. 



When the above-described specimen was directly compared with 

 the type it was found to differ only in being a little more robust. The 

 type seems to be a little more dried-out than the described specimen, 

 for its toes and the webbing between them are a little more shrunken. 

 Very faint traces of light dots are still discernible on the back of the 

 type. 



When compared directly with punctata, the species rhodoporus is 

 seen to differ in having a broader head and more rounded snout; in 

 having a larger tympanum (two-thirds to three-fourths the diameter 

 of the eye, while the tympanum of punctata is only about one-half the 

 diameter of the eye), and in being less conspicuously spotted.

Hyla sp. 



A single specimen (USNM 117511) from Rio Guaimaral, Atlantico, 

 we prefer to leave without a name. Its reduced webbing and build 

 seem to align it with the "green" Hyla group, but it is certainly dif- 

 ferent from the three species of that group presently recognized from 

 Colombia — punctata, rubeola, and rhodoporus. In general it seems more 

 like albomarginata, and the fact that its vomerine tooth rows are some- 

 what arched would seem to indicate that it might be allied to that 

 species. On the other hand, its tympanum is relatively larger than 

 that of albomarginata as redefined by Fouquette (1961, p. 595) ; it also 

 differs from that species in lacking a super-anal white line, white bars 

 on the heels, and a white ulnar ridge and white line on the tarsus; 

 furthermore, it has greatly reduced webbing on the fingers, and in this 

 respect it is less similar to albomarginata than it is to the other species 

 mentioned above. Since the specimen is faded and has been preserved 

 for quite some time, we prefer to hold specific identification in abeyance 

 until fresh material from the north coast of Colombia becomes avail- 

 able.
