Snout very short, broadly rounded, obliquely truncate at 

 the end, with nearly vertical, concave lores ; eyes large ; inter- 

 orbital space as broad as the upper eyelid ; tympanum very 

 small, not very distinct. Fingers short, dilated into enor- 

 mous disks, the width of which equals three fourths the width 

 of the eye ; a broad web, extending nearly to the disks, 

 between the two outer fingers, and a short one between the 

 second and third; toes very broadly webbed, the web en- 

 closing one half of the disks ; latter about half the size of 

 those of the fingers ; subarticular tubercles oval, flat ; no 

 distinct metatarsal tubercle. Hind limb very long and 

 strong ; the femoro-tibial articulation reaches the shoulder ; 

 tibia as long as the distance between the tympanum and the 

 vent. Skin finely granulate above, smooth inferiorly.

 and whitish dots on the sides ; limbs with lighter cross bands ;

 of Prof. Huxley * drew special attention to the group. These
