length of which equals the diameter of the eye; interorbital space 
deeply concave ; tympanum 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. boier, are absent on the anterior and middle portions 
of the back, but represented by two short series commencing in the 
sacral region and converging into a point above the vent. Brown
