1883.] GECKOS OF NEW CALEDONIA. 117 



Brest, Lisbon, Paris, and Brussels with those in the British Museum, 

 this work could not have been carried out ; and I beg leave to 

 express my sincere thanks to the heads of tbose scientific establish- 

 ments for having enabled me to fulfil my object. 



In order to render this paper a more useful guide, I have given 

 a short description of every species. These are all original, and 

 taken from typical or well-authenticated specimens. The synonyms 

 referring to Is^ew-Caledonian specimens are preceded by *. 



The number of species of Geckonidse actually known from New 

 Caledonia is fourteen ; two are recorded here for the first time, one 

 being new to science. 



The following is a list of what has been published on the sub-
