62916. Well preserved specimen of _Io spinosa_.
62955. Specimens of _Unio probatus_.
62914. A large specimen of shell pin, made from the columella of a
_Busycon perversum_. It is much discolored and in an advanced stage of
decay. Length nearly 4 inches. Form as usual.
62913. A shell pin similar to the preceding.
[Illustration: Fig. 140.--Shell gorget with an engraved cross.]
62931. A number of large shell beads, made from the columellae of marine
shells. The larger specimens are cylindrical in form, and are 1 inch
in length and upwards of 1 inch in diameter.
[Illustration: Fig. 141.--Shell gorget with the engraving of a
spider.]
62932-62834. Shell beads of various sizes and shapes, made from the
columellae and walls of marine shells.
62928. A shell ornament, on the convex surface of which a very curious
ornamental design has been engraved. The design, inclosed by a circle,
represents a cross such as would be formed by two rectangular tablets
or slips, slit longitudinally and interlaced at right-angles to each
other. The lines are neatly and deeply incised. The edge of the
ornament has been broken away nearly all around. It is represented
natural size in the cut. Fig. 140.
62929. This disk is somewhat more convex on the front than is indicated
in the engraving. It is 2-1/2 inches in diameter, and is quite thin
and fragile, although the surface has not suffered much from decay.
The margin is ornamented with twenty-four very neatly-made notches or
scallops. Immediately inside the border on the convex side are two
incised circles, on the 3 outer of which two small perforations for
suspension have been made; inside of these, and less than half an inch
from the margin, is a circle of seventeen subtriangular perforations,
the inner angle of each being much rounded. Inside of this again is
another incised circle, about 1-1/4 inches in diameter, which incloses
the highly conventionalized figure of an insect resembling a spider.
The middle segment of the body is nearly round and has near the center
a large conical perforation. This round portion corresponds to the
thorax of the insect and has four pairs of legs attached to it. It is
difficult to distinguish the anterior and posterior extremities of the
body. It is probable that the subtriangular figure below is intended
for the head, as the two circles with central dots are good
representations of eyes. Fig. 141.
