2. faher — group 



The species of this group of hylids — crepitans, faher, langsdorjffii^ 

 and pardulis — are all rather large in size, and have a flattened or 

 concave head, a prominent pollex rudiment equipped with a spur in 

 the males, and usually a smooth, thin skin which may have some 

 minute glandular ridges, but which is not similar to the heavy, thick 

 integument found in species of Group 1. One of the species, pardalis, 

 has skin of a rougher texture than others of the group, owing to the 

 scattered tubercles that appear in some individuals. 



These frogs range rather widely; crepitans occurs from Trinidad, the 

 Guianas, and Venezuela south to Santa Catarina, Brazil; the smith 

 frog, faber, whose voice sounds like the clangor of a blacksmith's 

 shop, is known from Minas Gerais to Rio Grande do Sul; langsdorjffii 

 is less common than the two preceding, but is known from Bahia to 

 Santa Catarina; pardalis is found from Venezuela and Surinam south 

 to Sao Paulo. 



For a statistical analysis of measurements of members of the faher 

 group here discussed, see pages 373 and 375.
