COMMON CHAMELEON. 25.5 



purpose tlie structure of the tongue is finely 

 adapted, consisting of a long, missile body, fur- 

 nished with a dilated and somewhat tubular tip, 

 by means of which the animal seizes insects with 

 great ease, darting out its tongue in the manner 

 of a Woodpecker, and retracting it instantane-

 also support a long abstinence, and hence arose 

 the popular idea of the Chameleon being nou-

 collapsed state, it appears in the utmost degree of 

 extenuation as if consisting of little more than a

 of an inch, or even more, especially on the edges 

 of the projecting parts of the head and jaws. 

 Down the back runs a series of obscure denticula- 

 tions or slight projections, forming a carina on 

 that part. The feet consist each of five toes, three 

 and two of which on each foot are connate, or
