Distinguished from the type by the presence of four more 

 or less distinct dark longitudinal bands on the upper surface 

 of head and body, which, however, may appear conspicuously 

 and disappear in the same individual; the black lateral streaks 

 always present. 



Perhaps a distinct species.

Vomerine teeth in two oblique series between the very large 

 choanae and beginning at their inner front edges. Head as 

 long as broad ; snout triangular, a little longer than the dia- 

 meter of the orbit; canthus rostralis angular; loreal region 

 oblique, slightly concave ; nostril nearer to the tip of the snout 

 than to the eye ; interorbital space a little broader than the upper 

 eyelid ; tympanum very distinct, ^/^ or ^/- the width of the 

 eye. Disks of fingers about half the size of the tympanum, 

 of toes smaller; fingers with a slight rudiment of web, toes 

 nearly entirely webbed; subarticular tubercles moderate; a 

 very small inner metatarsal tubercle ; the knee reaches the fore 

 limb, the heel far beyond the tip of the snout ; tibia '-^^ length 

 of head and body. 



Skin of head free; upper parts smooth, belly and lower 

 surface of thighs granular; a fold above the tympanum.
