The tbllowini"^ appear to be the only characters in which this 

 species differs from E. quinqneliiieatus: — No postnasal; a single 

 postinental ; light vertebral line (in the young) bifurcating on the 

 frontal, as in E. li/nve, enclosing a dark rhomboidal spot on the 

 forehead. 23 scales round the body ; nuchal shields two pairs.

Although very similar in proportions, scaling, and coloration to 

 E. quinquelineatus, the Japanese form may be easily distinguished 

 by the following characters : — A single postmental ; 24 or 20 scales 

 round the middle of the body, those of the two median dorsal series 

 usually a little broader than the others.
