In a number of cases advantage has been taken of the natural perforations of the shell, both to give variety to the outline of small pendants and to save the labor of making artificial perforations. A very handsome little specimen is shown in Fig. 9. The two indentations above and below represent two of the natural perforations of the shell; artificial perforations are made in each of the four corners or wings. It was also obtained from the island of San Miguel. Fig. 10 represents a leaf-shaped pendant with notched edges and a single perforation. It comes from the island of Santa Cruz. [Illustration: PL. XLVII--PLAIN PENDANTS--PACIFIC COAST FORMS. (1/1)] The examples given are typical of the very large class of ornaments derived from the _Haliotidæ_. The striking specimens shown in Plate XLVIII are, with one exception, made from shells of this class. The two sickle-shaped pendants illustrated in Figs. 1 and 2 are made from the broadened inner lip of the _Haliotis californianus_ (?). In one a single perforation has been made near the upper end; in the other there are two, one near each end. The faces have been neatly dressed and the corners ornamented with minute notches. They are from graves on Santa Cruz Island. Two exquisite specimens, also from Santa Cruz Island, are presented in Figs. 3 and 4. They have been cut from the body of a _Haliotis splendens_ (?), and finished with much care. Two perforations have been made near the upper margin, which is arched or curved while the lower is nearly straight. The edges are neatly notched. Although somewhat altered by exposure these objects are still very pretty. A very neat, well preserved little pendant is shown in Fig. 5. The specimen presented in Fig. 6 is peculiar in having a series of five perforations, one near the middle and the others near the ends. The example given in Fig. 7 has two perforations, one at each end. These are all made from species of the _Haliotis_. The specimen presented in Fig. 8 is made from the lip of a _Cyprea spadicea_ with very little change except the carefully made perforation. It is from the island of San Miguel. The idea of beautifying ornaments made from the _Haliotis_ and other shells by notching the edges may have been suggested by the natural notches characteristic of the _Cypreas_. [Illustration: PL.
