without tooth-like processes. Head very large, much broader 

 than long; snout rounded, slightly projecting, as long as or 

 slightly longer than the eye; canthus rostralis distinct, obtuse, 

 straight; loreal region very oblique, concave; nostril nearer to 

 end of snout than to eye; interorbital space flat, as broad as 

 the upper eyelid ; tympanum distinct, about '/g the diameter 

 of the eye. Fingers with slightly swollen tips, toes with small 

 disks; first finger extending beyond second, nearly as long 

 as third ; second one a little shorter than fourth ; toes -/g webbed, 

 the web reaches the disks, except that of fourth toe, two 

 phalanges of which are free ; the web penetrating between 

 the outer metatarsals; subarticular tubercles large; an oval, 

 flattened inner, and a rather indistinct, roundish outer meta- 

 tarsal tubercle; no tarsal fold; the heel reaches the temple; 

 tibia about 2^j.^ times in the distance from snout to vent; 

 when the hind limbs are folded at right angles to the body, 

 the heels do not overlap. 



Upper surfaces covered with prominent porous warts of 

 difl'erent size ; on each side of the back they are more elongate 

 and confluent, so as to form an interrupted dorsolateral fold, 

 which, however, does not extend beyond the sacrum ; a strong 

 fold above the tympanum ; belly and lower surface of thighs 

 feebly granulate, otherwise smooth below. From snout to 

 vent 150 mm.

Vomerine teeth in two short oblique series behind the level 

 of the choanae and not extending outwards beyond the vertical 

 of their inner edges; the space between the two series equal 

 to or less than the length of one of them; lower jaw without 

 tooth-like processes. Head large, a little broader than long;

 than the eye; canthus rostralis obtuse, slightly curved; loreal
