Vomerine teeth in two large patches, rather, closely approximate!, 

 oblique, and behind hind edges of choanse. Tongue broadly ovoid, 

 last third free, and hind edge generally convex, except slight median 

 emargination. Choanse smaller than vomerine patches of teeth. 

 InterorbitaJ flattened, upper eyelid § its width. Tympanum ellip- 

 soid, £ eye-diameter. 



Skin largely smooth, a few granules around vent and post-femoral 



region. 



No distinct fold across throat or breast.

Limbs all slender. Fingers free, and only outer toes one-third 

 webbed. First finger little longer than second, and slightly swollen 

 basally. Third finger longest. Tubercles on phalanges apparently 

 well developed. Disks on toes and fingers moderately small, rounded, 

 apparently not quite half size of tympanum. Toes slender, fourth 

 much longest. Apparently no tarsal fold, though hind tubercle 

 distinct. 



Color in alcohol pale gray-brown generally above, lower surfaces
