LACERTADiE. 



In the next figure, the under parts of a variety of the 

 same species are exhibited in outline, to shew the collar, 

 the abdominal plates, the prae-anal plate, those which are 

 perforated by the femoral pores, and the scales of the tail. 



In the whole of the sub-family of Lacertina the head is 

 covered by the number of plates designated above, differ- 

 ing only in some very trifling modifications of form. The 

 abdomen is covered by broad plates, as seen in the figure, 

 not imbricated, or lying one over another, as are the scales 

 of the back and tail, but applied to each other at the mar- 

 gins ; and these are arranged in longitudinal rows. There 

 is in all the species a distinct collar, composed of several 

 scales, larger than those which cover the throat, and quite 

 detached from the plates which cover the breast, which 

 they loosely overlay. The scales of the back and sides are 

 small, and imbricated. Those of the tail are always ar- 

 ranged in distinct and even whorls, are elongated and nar-
