Two very small groups of vomerine teeth between the choane. 
Head enormous, bony, with symmetrical ridges and patches of 
tubercles ; nostril nearer the eye than the tip of the snout; eye 
small ; upper eyelid produced into a horn-like appendage, the length 
of which does not equal the width of the orbit; interorbital space 
concave; tympanum moderately distinct. Back with a club- 
shaped bony shield. First finger longer than second ; toes slightly 
webbed ; subarticular tubercles not very prominent; inner metatarsal 
tubercle large, oval, compressed, wit blunt edge ; a rather indistinct 
tarsal fold. The hind limb being carried forwards along the body, 
the metatarsal tubercle reaches between the eye and the nostril. 
Skin of upper surfaces with small tubercles ; a cutaneous ridge on 
each side of the dorsal shield; smooth or slightly granular beneath. 
Brown above, the middle of the head and back, the club-shaped 
figure, a stripe on the scapular region, and cross bands on the legs

cave, brcader than the upper eyelid; tympanum slightly distinct. 
A bony dorsal shield. Fingers very short, first longer than second ; 
toes very short, half webbed; subarticular tubercles not much 
developed; inner metatarsal tubercle very large, shovel-shaped, 
black-edged ; a slight tarsal fold. The hind limb being carried 
forwards along the body, the metatarsal tubercle does not reach the 
eye. Skin tubercular above, granular beneath. Yellowish or
