VIRGINIA ELEGANS. 
Kennicott, 1859, Pr. Ac. N. Sc., Phil., 99. — 
“Resembles V. valeriae; vertical and occipital plates narrower. Dorsal 
scales very narrow and elongated, much more so than in JV. valeriae, dis- 
posed in 17 rows. 
“Color uniform light olivaceous brown above; dull yellowish white beneath. 
Readily distinguished from the nearly allied V. valeriae by the narrower 
dorsal scales in 17 rows instead of 15 as in that species,” Southern Ilinois 
and southward.
