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 

 they are found in many of the most remote islands of the great

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

 South Africa, and California; Phyllodadylus (8 sp.), widely 

 scattered in Tropical America, California, Madagascar, and 

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

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

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

 Australia; Gecko (12 sp.), Oriental region to New Guinea and
