Abstract

I HAVE recently put forward proposals for the classification of geckos1. In this paper the view was advanced that the amphicœlous condition of the vertebræ characteristic of the majority of geckos is secondary, derived from the procœlous condition found in all other recent lizards. Of the three families of geckos recognized the two which conserve primitive ophthalmological characters, Eublepharidae and Sphaerodactylidae, are procœlous. I therefore supposed that primitive geckos were procœlous and that the Gekkonidae s.s., which show the most complete conversion to secretive and nocturnal habits, are secondarily amphicœlous. More or less implicit in this view was the idea that the procœlous condition was early fixed in the definitive lizard stock.
