[Fig. 271] represents the back or convex side of the disk shown in [fig. 270]. The long curved lines indicate the laminations of the shell, and the three crescent-shaped figures near the center are perforations resulting from the deep engraving of the three lines of the volute on the concave side. The stone grave in which this ornament was found occupied the summit of a mound on the banks of the Cumberland River, opposite Nashville, Tenn.
