oval ; snout narrowed, as long as the diameter of the eye ; tympanum 

 half the diameter of the eye. Fingers free ; no projecting rudiment 

 of poUex ; longest toe webbed to base of penultimate phalange. The

 brown or blackish, with a broad black cross band between the eyes 

 and several across arm, femur, tibia, and tarsus ; feriiora uniform

Tongue large, oval, entire and free behind. Vomerine teeth in 

 two groups close together behind the level of the choanae. Head small, 

 as long as broad ; snout rounded, as long as the diameter of the eye ; 

 canthus rostralis obtuse ; loreal region nearly vertical ; interorbital 

 space as broad as, or a little broader than, the upper eyelid; tympanum 

 distinct, about half the diameter of the eye. Fingers and toes very 

 variable in shape ; in some specimens they are moderate, with rather 

 small dislfs, in others short and stout and with very large dilations ; 

 but as some specimens exhibit an intermediate structure, it is impos- 

 sible to attach a specific importance to this character, though, when 

 the two extreme forms are placed side by side, the diiference is a 

 very striking one. Fingers free or with a slight rudiment of web ; 

 no distinct rudiment of pollex ; toes two- thirds or three-fourths 

 webbed ; subarticular tubercles well developed ; a distinct fold along 

 the inner edge of the tarsus. The hind limb being carried forwards 

 along the body, the tibio-tarsal articulation reaches the shoulder or 

 the tympanum. Skin smooth above, granulate beneath ; a strong 

 fold across the chest. Greyish or reddish brown above, uniform or 

 speckled with darker ; a dark band on the side of the head and body ; 

 beneath whitish, immaculate. Male with a brown external subgular 

 vocal sac ; during the breeding-season the inner side of the first 

 finger is covered with brown rugosities. From snout to' vent 

 39 millim.
