thong. One of them (fig. 11, h) has three small incisions on one end. 

 The other tooth is plain. 



Grooved incisor 

 (1 specimen) 



A shallow groove, and part of a second, encircles the root of a large 

 incisor, probably bison. It is not polished, and may not have been 

 used (fig. 11, c) . 



WORK IN SHELL 



Dish heads 

 (10 specimens) 



Eight circular disk beads are 2 to 4 mm. thick and 10 to 12 mm. 

 in diameter (fig. 12, a). The circular perforations are ordinarily 

 drilled from one side of the bead. One specimen (fig. 12, h) has a 

 cylindrical hole that may have been drilled with a hollow reed. Two 

 irregular specimens, larger than the finished beads described above, 

 are 13 to 18 mm. in diameter. They are perforated, and the sides, 

 although smooth, are not regular (fig. 12, o-d) . 



Dishs 

 (10 specimens) 



Two disks are smoothly finished. One of them is 33 mm. in diam- 

 eter and 5 mm. thick, and the other is 11 mm. in diameter and 4 mm. 

 thick. The edges are smooth and rounded (fig. 12, k-l). The eight 

 remaining specimens are roughly circular pieces of shell 15 to 40 mm. 

 in diameter. Edges are irregular or partially smoothed. These 

 pieces may be rough-shaped blanks that were not brought to their 

 final form (fig. 12, m,n). 



Pendcmt 

 (1 specimen) 



A fragment of the shell of a Lctsmigona complanata^ with part of 

 the hinge, is broken through a perforation drilled through a thin 

 pai-t of the shell (fig. 12, j) . 



Fossils 

 (22 specimens) 



Seven species of fossil shells were found that had been picked up 

 elsewhere by the inhabitants and brought to the village. Five of the 

 seven species are pierced or otherwise modified for suspension as beads 

 or pendants. 



Three of the L. nehrascensis shells are beads (fig. 12, e) . The shell 

 wall is pierced by a longitudinal cut that is smooth and rounded. A
