postmental; light vertebral line (in the young) bifurcating on the 
frontal, as in &. lynwe, enclosing a dark rhomboidal spot on the

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 26 scales 
- round the middle of the body, those of the two median dorsal series 
usually a little broader than the others.
