192 SAURIA. 



This Lizard has been obtained in Dalmatia and Corsica, 

 where it is found among rocks on the mountains, never in

Genus PSAMMODROMUS. 



The tongue and teeth are as in the genus Lacerta, as is 

 the disposition of the plates of the head. There is scarcely

 being visible, with the scales upon it of the same size as 

 those adjoining. In front of each shoulder is a slight 

 curved fold ; ventral plates four- sided, and so arranged as 

 to form both transverse and longitudinal rows ; the toes 

 are keeled above, not toothed on their edges.

 only one naso-frenal plate, of a subtriangular shape ; the 

 temples are covered with hexagonal scales of nearly equal 

 size, those near the upper edge being keeled ; the eyelids 

 are clothed with very small granular scales ; the scales 

 of the throat, and neck beneath, are much tiled, flat, 

 smooth, subhexagonal, not separated from the scales of 

 the chest by a space covered with minute plates, as in the
