of the pyramidal rays. Outside of this again are the four symbolic birds placed against the side of the square opposite the arms of the cross. These birds, or rather birds' heads, are carefully drawn after what, to the artist, must have been a well recognized model. The mouth is open and the mandibles long, slender, and straight. The eye is represented by a circlet which incloses a small conical pit intended to represent the iris, a striated and pointed crest springs from the back of the head and neck, and two lines extend from the eye, down the neck, to the base of the figure. In seeking an original for this bird we find that it has perhaps more points of resemblance to the ivory-billed woodpecker than to any other species. It is not impossible, however, that the heron or swan may have been intended. That some particular bird served as a model is attested by the fact that other specimens, from mounds in various parts of Tennessee, exhibit similar figures. I have been able to find six of these specimens, all of which vary to some extent from the type described, but only in detail, workmanship, or finish. The specimen presented in Fig. 2, Plate LIX, was obtained by Mr. Cross from a stone grave on Mr. Overton's farm near Nashville, Tenn. Professor Putnam, who secured it from Mr. Cross, has published a cut of it in the Eleventh Annual Report of the Peabody Museum. It is made from a large marine shell, probably a _Busycon_, and is represented natural size both by Mr. Putnam and myself. The design is essentially the same as that shown in the type specimen, but is much more rudely executed. A circlet with a central pit takes the place of the cross and sun. The looped rectangular figure has but two lines and the birds' heads are not so full of character as those on the other specimens; they resemble the heads of chicks with a few pin-feathers sprouting from the back and top of the head rather than full-fledged birds. The design is engraved on the concave side. The perforations are much worn. This specimen is now in the Peabody Museum. [Illustration: PL. LVIII--SHELL GORGET--THE BIRD. Mississippi. (1/1)] The same collection contains a large fragment of another small disk about two inches in diameter. The central part seems to be plain, but the looped figure, which has four lines, resembles very closely that engraved on the other plates. It is mentioned by Professor Putnam, on page 309 of the Eleventh Annual Report of the Peabody Museum. It is said to have been found on the surface in Humphrey County, Tennessee.
