Gymnodactylus asper. 



Agrees very closely with G. miliusii, Bory, except in the 

 much larger and spine-like tubercles on the back and tail, 

 and in the coloration, the upper parts being uniform yellowish, 

 without any markings. The size of the specimen on which 

 this species is founded exceeds that of the largest G. miliusii 

 preserved in the British Museum.
