ORDER SAURIxV. Sll 



Near Paris there also exists another variety, having sixteen 

 callous tubercles under each thigh, the black of a bluish 

 green, with longitudinal white lines and blackish spots. 



Razaumowski, in his Natural History of the Jurat, has 

 described a third which comes from Switzerland, and which 

 has the under part of the tail a flesh-colour. The sides of 

 the body are green, spotted with black. There is a band of 

 brown spots along the back and tail. 



Finally, Daudin, in the Bois de Boulogne, caught a 

 fourth variety, the back of which is entirely of a reddish 

 brown and without spots, and which evidently, according to 

 him, is the same animal as the Seps ruber of Laurenti. 



The lacerta viridula of Latreille resembles much in its 

 form the lacerta stirpium. It was discovered by the Spanish 

 naturalist Ruiz de Xelva, in that part of Mexico which is 

 nearest the isthmus of Panama, where it lives in the clefts of 

 rocks, and in the middle of heaps of stones in the neigh- 

 bourhood of woods. The male may be distinguished by an 

 orange-coloured spot, surrounded by blackish, which it bears 

 upon the occiput and the neck. 



The lacerta tiliguerta, Gmelin, is an animal of a shining- 

 green, relieved by black spots and stripes along the back. 

 Its total length is from seven to eight inches. 



This saurian has as yet been described, after nature, only 

 by the naturalist Cetti. It is found at all seasons, in the 

 lawns, fields, and on walls, in Sardinia, where it is known 

 under the names of tiliguerta and caliscertula. 



M. de Lacepede regards the tiliguerta rather as a simple 

 variety of ocellata than as a distinct species, and our author, 

 as may be seen by the notes on the text, thinks that it is 

 only a mixture of an American ameiva with the green 

 lizard of Sardinia, ill-described by Cetti. 



The nimble lizard, scaly lizard of Pennant (Lacerta 

 agilis, Linnaeus), has the head triangular and depressed,
