AMEIVA SEX-LINEATA. 113 



The habits of the Ameiva sex-lineata closely approximate it to the true 

 Lizards, of which we have none in the United States, and it may fairly be 

 considered their representative here. 



Dumeril and Bibron have arranged this animal in the genus Cnemidophorus, 

 (Wagler, Wiegmann,) restricted by themselves so as to difter from that of 

 Ameiva, in the tongue being destitute of a sheath at its root into which it can 

 be received. "Les Cnemidophores sont pour ainsi dire des Ameiva's a langue 

 non engainante," &c.
