The presence of two pairs of nuchal scales distinguishes this 
species from M. 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 supraciliary 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.
