Fingers and toes free or slightly webbed, first opposable to the others, 

 the tips dilated into regular disks. Outer metatarsals united. 

 Omosternum cartilaginous; sternum cartilaginous. Diapophyses of 

 sacral vertebra strongly dilated. 



Four species of this genus are known from southeastern Brazil. 

 When their habits are known they are not difficult to collect, as they 

 sleep in leaf axils during daylight and descend to the ponds only at 

 nightfall. Their movements are slow and languid compared to other 

 Hylidae, and they allow themselves to be picked up without showing 

 fear. 



The species from southeastern Brazil are separated by the following 

 characters: 



a'. First toe shorter than second; a dermal heel appendage. 



6'. Eardrum quite distinct; anal region less granular . appendiculata (p. 196) 

 62, Eardrum not very distinct; anal region more granular . . . guttata (p. 201) 



o*. First toe longer than second; no dermal heel appendage. 



fci. No vomerine teeth rohdei (p. 204) 



b^. Vomerine teeth present burmeisteri (p. 198) 



For a statistical analysis of measurements of these species, see 

 pages 373 and 379.

Description. — Adult male, USNM 97147 (cotype of Phyllomedusa 

 appendiculata), Sao Bento, Santa Catarina. No vomerine teeth; 

 tongue cordiform, one-half as wide as mouth-opening, with a very 

 deep notch on its free posterior border ; snout short, rounded when seen 

 from above, truncate and vertical in profile, not projecting beyond 

 lower jaw; nostrils lateral, almost at tip of snout, separated from each 

 other by an interval equal to their distance from eye. Canthus 

 rostrahs angular and distinct; loreal region sUghtly concave and 

 somewhat diagonal. Eye large, projecting, its diameter slightly less 

 than its distance from end of snout; interorbital diameter 1}^ times the 

 width of upper eyefid, much greater than distance between nostrils. 

 Tympanum fairly distinct, though covered by skin, a low glandular 

 swelling along its upper border, a distinct glandular skinfold leaving 

 its lower posterior margin and terminating above and behind the 

 shoulder; diameter of tympanum about two-fifths that of eye, sepa- 

 rated from eye by an interval equal to about one-half its own diameter. 

 No parotoid gland. Fingers moderate in length, nearly one-third 

 webbed, first shorter than second and apparently only sUghtly op-
