l62 CLASSIFICATION OF REPTILES. 



fish, whose pectoral fins, as it were, are turned into 

 wings. Sitana is a perfect prototype of the Diodon^, 

 Tetraodons, and other cheloniform fishes of the order 

 Plectognathes. Some of the Agamidce have their hodies 

 covered with spines^ and thus remind us of the hedge- 

 hogs and globe-fish (Diodori) ; while Phrynosoma, and 

 the other orbicular lizards, represent the amphibian 

 frogs. This^ in short, is perhaps the most interesting 

 group in the whole circle of the saurian reptiles ; and 

 would repay, in popular and pliilosophic interest_, more 

 than any other, the labour of a complete and searching 

 analysis of the whole^ with reference both to its affinities 

 and analogies. 



(167.) Thus fortified in our conviction that the 

 natural arrangement of the reptiles would be in perfect 

 unison with that of all the other vertebrated animals, 

 we shall now compare the families of the saurians, or 

 lizards, with the other groups here indicated.

In groups so immensely remote and dissimilar our sur- 

 prise must be excited at discovering so many points of 

 analogy as the above table discloses, rather than our dis- 

 appointment be expressed at not comprehending others. 

 We have but scanty room for a full exposition of this 

 table, but a few remarks may possibly put the reader on 

 the road for discovering more. The Lacertidcp, as a whole, 

 are the most expert climbers, for they run with ease 

 up walls and trees perpendicularly, while the typical
