 tympanum distinct, small, less than half the diameter of the eye; 

 tympanum bordered above by an indistinct glandular fold that curves 

 down behind the shoulder and is lost; canthi sharp and passing just 

 inside the external nares, blunted on snout ; nostrils closer to tip of 

 snout than to eye; distance from nostril to eye equal to or slightly 

 less than distance between nostrils. 



Vomerine teeth prominent, divergent in an anterior direction, ex- 

 tending to or slightly beyond a line drawn between anterior borders 

 of the choanae; tongue as broad as long and notched behind; vocal 

 sacs open into narrow slits on each side of, just beneath edges of, and 

 three- fourths of the way back of tongue. 



Finger pads well developed, that of third digit as large as tym- 

 panum; prominent granular tubercle on thumb, lying parallel and 

 just anterior to median palm tubercles (which also extend well onto 

 base of thumb) ; lateral palmar tubercle divided, granular, and in- 

 distinct; second and fourth subarticular tubercles slightly larger than 

 third; subterminal articular tubercle on outer finger bifid; supernu- 

 merary tubercles prominent on the second and third fingers; indis- 

 tinct glandular ridge from outer palmar tubercle to the elbow ; web 

 between third and fourth fingers extends to the subterminal joint; 

 strong definite web between the second and third fingers ; slight web- 

 bing between first and second fingers; a marked ridge along lateral 

 aspect of all fingers. 



Three metatarsal tubercles present, medial many times larger than 

 lateral ; latter represented by a single small punctate elevation ; inter- 

 mediate tubercle indistinct, one-half size of median ; foot almost com-
