Vomerine teeth in two oblique series extending much beyond the 

 level of the hinder edge of the choanae. Head moderate ; snout 

 rounded : tympanum distinct, half the size of the eye ; interorbital 

 space as broad as the upper eyelid. Fingers moderate, first ex- 

 tending beyond second ; toes broadly webbed, with slightly swollen 

 tips ; subarticular tubercles of fingers aud toes well developed ; nn 

 oblong inner metatarsal tubercle. The hind limb being carried 

 forwards along the body, the tibio-tarsal articulation reaches the 

 eye. Skin smooth ; upper eyelid tubercular ; a fold from the pos- 

 terior angle of the eye to the shoulder. Brown above, with a few 

 reddish spots ; hinder side of thighs marbled with dark brown.

Yomerine teeth in two strong oblique series commencing from the 

 inner anterior angle of the choante ; lower jaw with two fang-like 

 bony prominences in front, sometimes scarcely developed. Head 

 large ; snout rather pointed ; occiput more or less swollen on the 

 sides ; interorbital space generally one half broader than the upper 

 eyelid ; tympanum distinct, variable in size, generally much smaller 

 than the eye. Fingers moderate, first much longer than the second ; 

 toes broadly webbed, with distinctly swollen tips ; subarticular tu- 

 bercles of fingers and toes well developed ; inner metatarsal tubercle 

 elongate, blunt ; no outer tubercle. The hind limb being carried 

 forwards along the body, the tibio-tarsal articulation readies the eye 

 or a little beyond. Skin smooth above, or with small rounded warts ; 

 upper evelid tubercular : a strong fold above the tympanum. Brown 

 or blackish above ; sometimes a light dorsal stripe. Male without 

 vocal sacs. 



Young specimens bave a very different ajipearance from that of 

 the adult, having a narrow glandular fold on each side of the back, 

 and the interorbital space not broader than the upper eyelid. 

 Gradually the glandular fold disappears and the interoi'bital space 

 becomes broader.
