rows of femoral plates and three or four of tibials. Femoral pores 

 fifteen to twenty-three. Digits feebly serrated ; fifth toe short, not 

 extending as far as inner. Caudal scales feebly keeled, especially 

 inferiorly. The coloration varies considerably. The young are 

 olive-brown with darker markings or white dots, and have con- 

 stantly a black, white-edged baud on each side, commencing from 

 the eye and extending on the tail. With age, these bands dis- 

 appear generally, but they are retained by some female specimens. 

 Usually, the upper surfaces are greenish, more or less spotted or 

 reticulated with black, especially on the sides, where there are 

 round white spots which, in males, may be confluent into vertical 

 bars. In a few specimens, there are five more or less distinct 

 longitudinal light dark-edged lines on the body. Lower surfaces 

 greenish-white, black-spotted on the sides.
