Vomerine teeth in two oblique series between the rather 

 large choanae, beginning from their inner front edges. Snout 

 truncate, as long as the orbit; canthus rostralis angular; loreal 

 region concave; nostril close to the tip of the snout; inter- 

 orbital space as broad as the upper eyelid; tympanum distinct, 

 half the diameter of the eye. Disks smaller than tympanum; 

 fingers with a slight rudiment of web ; toes nearly entirely 

 webbed, the penultimate phalanx of fourth toe free; subarti- 

 cular tubercles moderate; a small inner metatarsal tubercle; 

 the knee reaches the shoulder, the heel far beyond the tip 

 of the snout. 



Finely granulate above, coarsely granulate on the belly. 



Dark grey-brown above; lips with darker vertical bars; one 

 or two small black spots above the axil; limbs with dark

Vomerine teeth in two oblique series beginning from the 

 inner front edges of the choanae. Head as long as broad ; 

 snout rounded; canthus rostralis distinct; loreal region feebly 

 concave; nostril nearer to the tip of the snout than to the eye; 

 interorbital space twice the width of the upper eyelid ; tym- 

 panum very distinct, oval, its diameter equal to the distance 

 between the nostril and the tip of the snout. Disks of fingers 

 large, of third finger almost as broad as the smaller diameter 

 of the tympanum; first finger shorter than second; fingers 

 2 / 3 webbed ; toes, with exception of the fourth, webbed to the 

 disks; subarticular and inner metatarsal tubercles feebly pro- 

 minent ; no outer metatarsal tubercle ; the heel reaches beyond 

 tip of snout. 



Occiput with four stiff spine-like processes: a laterally com- 

 pressed one above each tympanum, and two between the tym- 

 pana ; skin of upper surfaces with small warts or tubercles; a 

 narrow fold along the outer edge of the fourth finger, and
