 three or four lower labials, anterior longest ; mental large, truncate 

 posteriorly. Upper eyelid with a very small spine-like scale. Head 

 covered with granular scales, which are not larger, and slightly 

 keeled on the snout. Dorsal scales very large, much larger than 

 ventrals, rhomboidal, strongly keeled, and imbricate ; they form 

 about eighteen longitudinal series. Gular scales minutely granular ; 

 abdominal scales large, imbricate, smooth. Tail cylindrical, tapering, 

 covered with large strongly imbricate scales ; those on the upper 

 surface keeled ; a series of feebly enlarged scales inferiorly. Light 

 pinkish-brown above, with six lighter, dark-edged, transverse bands 

 on the body; head with two white streaks from the tip of the 

 snout to the neck, and another on each side from eye to ear ; tail 

 completely encircled by eight brown annuli, becoming gradually

 brown chevron-shaped bands.
