There can be little doubt that the Geckonide are a very 
old family of the Lacertilia, which go back at least to the lower 
Cretaceous, if not to the upper Jurassic. The distribution of 
the genera enumerated is very instructive. 
Gehyra mutilata Wiegm. extends from the Mascarene Islands 
to the Seychelles, Ceylon, to the Malay Peninsula, Indian 
Archipelago, Philippines, Moluccas and New Guinea; it also 
occurs in western Mexico. This distribution again shows that 
there has been a land area reaching from the Mascaranes to 
New Guinea. The next species Gehyra oceanica Lesson reaches 
from the Moluccas eastward to the Cook Islands (Rarotonga), 
being found on the Admirality, Solomon, Fiji, Tonga an 
Samoa Islands, Savage Island and Lord Howe's Island. Gehyra 
voraz Girard extends this area to the New Hebrides, the 
Loyalty Islands and Norfolk Island; Gehyra brevipalmata to 
the Pelew group and Gehyra insularis to the Sandwich Islands. 
This distribution can only be explained by a former Indo- 
Pacific Continent extending from Malaysia to the west coast of 
America. 
The distribution of the species of Perochirus Boulenger and 
Lepidodactylus Fitzinger give new proof for the former exist- 
ence of this continent.

Family Seincide. 
The family Scincide contains several genera, showing @ 
very interesting geographical distribution.” These genera 
are Lipinia Gray, Emoa Gray and Ablepharus (A. bouton 
Desjard). 
Lipinia Gray.
