D. Convex edges; stem usually tapering with straight base, though it is noticeable that some are straight with convex base. Resembling the last in form, but slender; from 1¾ to 4¼ inches long. From western and central North Carolina; Kanawha valley, West Virginia; and Savannah, Georgia.

E. Differing from specimen shown in [figure 203], in having the edges expand at the shoulders in a projection or point, and varying more in size, some being small enough for arrowheads. All from Savannah (including the example shown in [figure 205]) are of smoother finish than those from other sections, and are usually larger, ranging from 2½ to 4½ inches long. There are some from this locality with base straight or convex. Found also in western and central North Carolina; Kanawha valley; South Carolina; eastern Tennessee; Coosa valley and northeastern Alabama; Brown county, Illinois; northeastern, southeastern, and southwestern Arkansas; and southwestern Georgia.
F. Edge having a double curve, being convex toward the point, and curving outward at the shoulders. Few of them are barbed, though many have the shoulder much expanded. Base sometimes convex or concave, but more often straight; in a few it is somewhat pointed. In most of the smaller specimens the base is notched, but of these none are over 2½ inches long. Stem tapering or expanding, rarely straight. A few have the base rubbed smooth and dull, or even polished (this feature appears in other forms, as noted); it seems to result from use as a knife or scraper, but the implement as a whole does not appear to be adapted to such use. None of them are over 3½ inches long, except a few from Savannah; all from there are wide, but from other places the longer ones are all narrow.
