Although I have not had an opportunity of examining this specimen closely, I am inclined to the opinion, judging by its outlines, that the shell from which it was made has been sinistrally whorled, and hence a _Busycon perversum_. I should also prefer to consider the hole beneath the nose as representing the mouth, as it certainly does in many other cases, and the peculiar figure--the three vertical lines which extend downward from the hole and the two banded figures that cross them at right angles--as a representation of some painted or tattooed design characteristic of the builders of the mound. [Illustration: PL. LXVIII--SHELL MASK. Virginia. (1/2)] Other examples of these objects are represented in Plate LXIX. Of especial interest I may mention the specimen shown in Fig. 4, obtained, with other similar examples, by Professor Putnam, from the Lick Creek mound, in East Tennessee. The perforations which represent the eyes are surrounded by two concentric circles, and the zigzag lines beneath are supplemented by two sets of pendant figures formed of notched lines, the two longer of which extend down the sides of the nose, the others being connected with the lower margin of the eye. In one example four parallel lines pass from the mouth downward over the chin. Fig. 3 represents a specimen from the Brakebill Mound, East Tennessee. The mouth is not indicated, and the nose is but slightly relieved. Each eye, however, is inclosed by a figure which extends downward over the cheek, terminating in three sharp points.

Mound, Ely County, Va.] So far as the specimens at hand show, this peculiar embellishment of the eyes and mouth is characteristic of Virginia and East Tennessee. A small specimen from Georgia, now preserved in the Natural History Museum at New York, has a somewhat similar ornamentation of the eyes. This specimen is shown in Fig. 6, Plate LXX. In Fig. 8 of the same plate we have the representation of a face modeled in clay, on which a number of incised lines, similar to those engraved on shell, have been drawn. The crown of notches is also present. The specimen has been illustrated by Professor Jones.[152] It is now in the museum of Natural History at New York, and was probably obtained from the Etowah Valley, Georgia. Examples in stone are also numerous, and show certain features in common with those in shell. Fig. 9 is from Northern Ohio, and is carved from a nodule of iron ore.
