 base of the tail, and above it a white band over the supercilium 

 and along the back and another through the upper labials and ear 

 to the shoulder. A faint broken blackish line from the gape to

The greater number of rows of scales, between the limbs besides 

 other points of difference, distinguish this species from carina- 

 tus, macularius, septimlineatus, and olivaceus, and its coloration 

 and greater number of keels from trivittatus.
