A much larger specimen, which resembles my type specimen very closely, is shown in Fig. 1, Plate LIX. It was obtained by Professor Putnam and Dr. Curtis from a stone grave on Mrs. Williams' farm, Cumberland River, Tennessee. It is nearly circular, and about two and a half inches in diameter. A small piece has been lost from the upper margin. It is neatly made and quite smooth, and the lines of the design are clearly and evenly engraved. The small cross in the center is inclosed by a plain narrow zone, and is defined by four triangular perforations between the arms. In this respect it resembles other shell crosses found within the Mississippi Valley. Surrounding the plain zone are eight pyramidal rays with cross-bars; in this feature, and in the drawing of the looped square and the birds' heads, there is but little variation from the type specimen. The surface upon which the engraving is made seems to be slightly convex. Another specimen of this class was obtained from a stone grave near Gray's mound, at Oldtown, Tenn. It is shown in Fig. 3, Plate LIX. The design is very much like that of the type specimen, from which it differs in having four large perforations near the center. Although the engraved design which once occupied the central space is almost totally effaced, one or two of the tips of the pyramidal rays may be detected. It is probable that the four round perforations correspond to the four triangular ones by which the arms of the cross in the preceding example are defined. The perforations for suspension are near one margin, and seem to be very much worn by use. The whole object is fragile from decay. This specimen is also in the Peabody Museum. One more very imperfect specimen obtained from a stone grave in the Cumberland Valley is nearly five inches in diameter and very irregular in outline. Barely enough of the engraved design remains to show that it belongs to the class under consideration.
