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

 deeply concave ; tj'mpauum hidden. First finger considerably longer

 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 G. boiei, are absent on the anterior and middle portions 

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