The specimen shown in Fig. 3 belongs to a necklace now in the national collection. This necklace was obtained from the Indians of New Mexico by Lieutenant Whipple, and consists of three of these shell ornaments, together with about fifty small porcelain beads. The shell beads are strung at regular intervals. The specimen illustrated is ornamented with a design in minute conical pits, arranged precisely as are the circlets in the crosses and encircling bands of the New York and Ohio specimens. The edges and surfaces are much worn by use. The substance of the shell is well preserved, and has an ivory-like appearance although in the specimen shown in the cut the lamination of the shell is distinctly seen. The perforations in these three specimens are quite symmetrical, and suggest the use of machinery. The method of perforation is identical in all these specimens, and will be readily understood by reference to the two sections given in Figs. 5 and 6. All of these specimens are nearly circular; but the regularity of the outline is in some cases marred by shallow notches produced by wear at the perforations. This wear has been accelerated by the abrasion of the small beads with which the disks have probably been strung. It will be noticed that there is quite a close resemblance between these objects and the "runtees" of the early writers. Beverly gives an illustration of an Indian boy who is described as wearing a necklace of these "runtees," which "are made of the Conch Shell, as the Peak is, only the Shape is flat and like a Cheese, and drill'd Edge-ways."[64] A portion of this illustration is copied in Fig. 5, Plate XXXVI. It will be seen by reference to this cut that the manner of stringing corresponds with the method in which the objects under consideration would have to be strung. [Illustration: PL.

(1/1)] It is probable that the signification of the designs engraved upon these ornaments will remain forever a matter of conjecture. It cannot be affirmed that the cross, which occurs on the faces of most of the specimens, has any particular significance, although it may represent the points of the compass. That it may have some emblematic meaning is, however, not impossible. I have counted the number of circlets on all of the specimens with which I am acquainted. The result is shown in the following table:
