GENUS VIII. STELLIO. STELLIOS. 



Body oblong, thick, entirely covered with small scales, 

 regularly disposed transversely ; tongue thick, short, 

 and a little cleft at the tip ; head broad, rather short, 

 covered above with numerous scales or plates ; throat 

 capable of slight inflation ; tail compressed, surround- 

 ed with transverse rows of large carinated pointed 

 scales ; feet strong, furnished each with five separate 

 toes, tipt with claws. 



This singular tribe of reptiles, which, in the form of 

 their bodies and the tubercles with which they are of- 

 ti'ii covered, bear some resemblance to the toads, are 

 found only in the hottest parts of Africa and America. 

 They hide themselves during the day below stones, and 

 in the crevices of old buildings, and leave these retreats 

 at the approach of night. They prefer dry situations, 

 and live chiefly on insects. 



Daudin has characterised nine species, which he ar- 

 ranges under three Sections, as follows. 

 SECT. I. Cordyli. 



Plates upon the head, body, and tail versicillated and 

 spinous. 



Species \. Stellio cordylus. Cordyle S. Head plated 

 above, body ami tail covered with pointed carinated 

 scales, disposed in whirls.
