Vomerine teeth in two strong, oblique series between the 

 choanae and extending behind the level of their posterior 

 borders. Head as long as broad or slightly longer; snout obtu- 

 sely pointed, projecting, as long as the upper eyelid, much 

 longer than deep; canthus rostralis angular, straight; loreal region 

 nearly vertical, concave ; nostril nearer to the tip of the snout 

 than to the eye; interorbital space about as broad as the upper 

 eyelid; tympanum very distinct, 2 /.5 to 3 / 4 the diameter of the 

 eye. Disks of the two outer fingers from slightly more than half 

 to as large as the tympanum, of first and second fingers and 

 of toes much smaller; disks of second finger elliptic (longer 

 than broad) ; first finger as long as or a little shorter than 

 second, which is shorter than fourth ; fifth toe longer than 

 third; toes webbed to the disks; outer metatarsals separated 

 nearly to the base; subarticular tubercles strong; an elliptic, 

 feebly prominent inner, no outer metatarsal tubercle; no tarsal 

 fold; the heel reaches beyond the tip of the snout; tibia 2 / 3 

 length of head and body, or nearly so long; when the hind 

 limbs are folded at right angles to the body, the heels are 

 strongly overlapping. 



Upper parts granulate; a feebly developed glandular dorso- 

 lateral fold ; a fold from below the eye to the shoulder, often 

 followed by one or two glandules; smooth beneath. 



Uniform purplish brown (green in life ?) above, usually darker 

 on the sides, especially of the head ; a white or whitish streak 

 along the upper lip, extending to the shoulder and followed 

 by a spot of the same colour; limbs usually with dark cross- 

 bars, which however may be very indistinct; white (in life 

 yellow?) beneath, uniform, or spotted or marbled with brown. 

 From snout to vent 97 mm. (the $ much smaller than the 9). 



Terminal phalanges T-shaped. 



Male with internal vocal sacs.
