length of which equals the diameter of the eye ; interorbital space 

 deejjly concave ; tympanixm hidden. First finger considerably longer 

 than second ; toes, webbed at the base ; subarticular tubercles much 

 developed ; inner metatarsal tubercle oval, blunt. The hind limb 

 being carried forwards along the body, the metatarsal tubercle 

 reaches the eye. Skin granular above and beneath, the granules 

 of unequal size ; the two dorsal lines of tubercles, which are so con- 

 spicuous in C. hoiei, are absent on the anterior and middle portions 

 of the back, but represented by two short series commencing in the
