ZONURUS. . . , t c A 4^u ^ 



From a re-examination of a specimen in spirits, 1 hnd that 

 the teeth of this genus are placed on the inner side ot the 

 jaws, and therefore it ought to be referred to this tamiJy. i 

 was misled by seeing only a dried specimen, and by buvier s 

 expressly describing the teeth as \n Agama. 1 may observe, 

 that the best way to examine the structure of. the reeth is to 

 take a needle and turn down the inner gums from the edge ot 

 the teeth; when if they are placed on the inner edge ot the 

 iaw, their roots will be distinctly seen; while if they are only 

 on the edge, the bone of the jaw will be smooth and of a uni- 

 form colour. „ ^ , 1 • 



The genus should be arranged after Cycliira, having no 

 palatine teeth and being provided with femoral pores : but it 

 may be easily separated from it, by the large size and peculiar 

 form of the shields of the head.
