 five narrow longitudinal black lines down the back. A deep 

 brown band from the nostril over the ear down the side to the 

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

 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 earina- 

 tus, macularius, septimli/neatus, and olivaceus, and its coloration 

 and greater number of keels from trivittatua.
