Luperosaurus, Gehyra, Ptychozoon, Lepidodactylus and a few more in that

Hmm, that's gonna be hard.. It's in Dutch... But I will work on a
translation again..

Strange enough, the Phelsuma's demonstrate a different pattern. There, one
groupof islands seems to be inhabited by a group of more or less related
species: i.c the Comores, the Mascarenes, Seychelles or Andamanes have
closely related species. This is most evident in the Mascarenes.
But, Phelsuma's as a whole are still too much alike. There are a couple of
very much bleeched specimen in the Zoologicalmuseum of Amsterdam waiting to
be identified by whoever wishes to disagree...
