I. Triangular, notched in from the bottom; barbs extend down even with the base, or the base is sometimes worked back, leaving it shorter than the barbs; some are beveled ([figure 274]). The same form is found in southwestern Georgia.

J. Broad; straight edges; base straight or concave; stem straight or expanding; long, rounded barbs ([figure 275]).

K. From Arkansas county, Arkansas, there is an implement of basanite or black jasper, of the general type of [figure 180] or 182, the point being broken off. The base has been worked down to a sharp edge, the stem highly polished on both faces. This polish does not extend to the faces of the blade, but both edges are rubbed smooth so far as they now extend. Whether the implement was originally pointed and used as a knife or spear, this sharp edge being given the stem after it was broken, or whether it was so made in the first place, can not be determined. Like the various forms with polished base, the specimen seems to indicate a manner of mounting or of use the reverse of what would be expected. It is shown in [figure 276].
