THE CAPE GECKO 



Pbyllodactylus unctus, (Cope) 



The scalation of the body is uniformly small. As with 

 the preceding species, the toes are much expanded at their tips 

 and form adhesive climbing organs "suckers." As the species 

 is confined to the Cape Region of Lower California, where but 

 one other gecko is found the preceding and that is distinctly 

 different in scalation, no lengthy description of the present rep- 

 tile is necessary. 



Colouration. Gray above.with five broad, blackish cross-bands 

 on the body, which are paler in their centres; tail also banded. 

 A dark band on each side of the head, passing through the eye. 



Dimensions. Similar to the preceding species. 



Distribution. The Cape Region of Lower California. 



The Genus Sphczrodactylus: About twenty species are 

 known. They inhabit southern Mexico, Central America, Colom- 

 bia and the West Indies. One occurs in southern Florida. 



THE REEF GECKO 



Spbaerodactylus notatus, (Baird) 



A very small species, but with much coarser scalation than 

 the preceding ones; the scales are keeled. Tail thick and short; 

 limbs small and with expanded toes. 



Colouration. Brownish yellow, with scattered, circular 

 spots of reddish-brown; these spots fuse, on some specimens, 

 producing dull bands, extending lengthwise; usually a central, 

 dark marking on the head, becoming broader in the rear. 



Dimensions. Total Length 2| inches.
