1. PHYLLODACTYLUS 51 



Suborder I. SAURIA (Lizards) 

 Family 1. GEKKONID^ 



This family of many genera of small lizards differs from 

 the Eublepharida; chiefly in the possession of amphicoelous 

 vertebra;, and ununited parietal bones. The clavicle is ex- 

 panded proximally. The eyes are large, without movable 

 lids. One representative of this family has been found in 

 the western part of the United States, but two species of the 

 genus Phyllodactylus occur in Lower California. 



Genus 1. Phyllodactylus 



PAyllodaciylus Gray, Spicil. Zool., 1830, p. 3. 



This genus includes a large number of species from 

 Tropical America, Africa and Australia. The digits are 

 rather slender, free, with transverse lamellae or tubercles in- 

 feriorly, and with tips dilated and covered below by two large 

 plates separated by a longitudinal groove. The pupil is ver- 

 tical. Males have no pores. The Lower Calif ornian species 

 may be distinguished by the following
