The presence of two pairs of nuchal scales distinguishes this 

 species from 21. agilis. The snout is usually longer and narrower. 

 Frontonasal usually not broader than long. Usually five upper 

 labials anterior to the subocular. Otherwise the structural cha- 

 racters are identical. Olive or bronzy above, uniform or with small 

 dark brown spots ; two light bands on each side, most distinct 

 anteriorly, separated by a broad dark brown band ; the upper light 

 band is the broadest, and begins on the end of the snout and follows 

 the canthus rostralis and the supraciHary border ; from the latter to 

 the scapular region it is edged internally by a dark brown band ; 

 The lower light band begins on the lip. Lower surfaces yellowish 

 or greenish.
