The Geckoes, or Wall-Lizards, form an extensive family, of 

 almost universal distribution in the warmer parts of the globe ; 

 and they must have some exceptional means of dispersal, since

 following are the larger and more important genera : — 



Oedura (3 sp.), Australia ; Diplodadylus (8 sp)., Australia,

 Queensland ; Hemidadylus (40 sp.), all tropical and warm 

 countries ; Peropus (12 sp.), the Oriental region, Papuan Islands, 

 Mauritius, and Brazil ; Pentadactylus (7 sp.), Oriental region and 

 Australia; Gecl:o (12 sp). Oriental region to Xew Giiinea and
