122 CLASS REPTILIA. 



Agama. Daud. 



Have a great resemblance to the common stelliones, 

 especially in their inflated head ; but they are dis- 

 tinguished by the imbricated, and not verticillated 

 scales of the tail. Their maxillary teeth are nearly 

 the same as those of the others, and they have no 

 palatine teeth.* 



The Common Agama. 



Some scales raised into a point or tubercles, bristle 

 in various parts of the body, and especially in the 

 neighbourhood of the ears ; with spines, sometimes 

 grouped, sometimes isolated, A range of them is 

 occasionally seen upon the nape ; but they do not 

 form the spangled crest which characterizes the 

 calotes. The skin of the throat is flabby, folded 

 crosswise, and susceptible of inflation. 



There are some species in which the thighs have a 

 series of pores. 



The Ocellated Agama of New Holland. Ag. Barhata^ 



Is very remarkable from its magnitude and extra- 

 ordinary figure. A series of large spiny scales pre- 



-j- Agama, from a.yc(.(xog (unmarried). It is not easy to conjecture 

 why LinnPBus should have given this name to one of those lizards. Daudin 

 has extended it to the entire subgenus into which this species should enter, 

 and believes that Agama is the national name.
