species and subspecies are common where they occur, at least 

 in certain parts of their range, or perhaps one should say 

 that their habits are such as to make them more readily

The following table may be of use in the identification 

 of the lizards of this genus. It shows the number of dorsal 

 scales in a row from the interparietal plate to a line joining 

 the backs of the thighs, the number of dorsal scales equal to 

 the length of the head from the end of the snout to the 

 back of the interparietal plate, and the number of femoral 

 pores, in each species and subspecies.
