Both are made of extremely thin, brittle pottery painted a dirty yellow and polished throughout, with no ornament except a broad red stripe, which passes obliquely around the whole of the outer surface of each vase. (e) Two shallow circular plaques, painted reddish-brown, and polished throughout, with a geometrical device in thin black lines around the inner surface of the rim of each. (f) A quantity of bones, probably those of a _halib_ or gibnut, and of a wild turkey. These were found under a large block of rough limestone. (g) A number of univalve shells, each about 1 inch in length, perforated at the apex in two places, as if for suspension in the form of a necklace or ornamental border.[43] With these shells was found half of a large cockle-like bivalve, painted red throughout, and perforated, possibly for use as a gorget. (h) Thirteen large, round, perforated beads (fig. 55). Some of these are reddish in color, and show traces of polishing. With these were the three jadeite beads pictured in figure 56; two of these are cylindrical, with a knob at one end, while the third is nearly spherical; all are finely polished; they are made of light and dark-green mottled jadeite. (i) A single small oyster shell, with a great number of cockle shells. (j) Two circular disks of shell, represented in figure 57, _a_, exhibiting the front and back view. The central part is of a deep reddish color, and is well polished. Each disk is 5 cm. in diameter and is perforated at the center. They were probably used as ear ornaments. Excavations were made in this mound to the ground level, but no additional objects were found in it.
