Two veiy small groups of vomerine teeth between the choanse. 

 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, with blunt edge ; a rather indistinct 

 tarsal fold. The hmd 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 

 bluish. Male with a subgular vocal sac.

Vomerine teeth in two small groups between the choanae. Palatine 

 ridges more or less distinctly denticulated. Head large, bony, 

 rough ; nostril nearer the eye than the tip of the snout ; upper 

 eyelid slightly pointed, triangular ; interorbital space slightly con- 

 cave, broader 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 largo, shovel-shaped, 

 black-edged ; a slight tarsal fold. The hind limb being carried 

 forwards along the Iwdy, the metatarsal tubercle does not reach the 

 eye. Skin tubercular above, granular beneath. Yellowish or
