DISK BEADS AND OTHER SMALL BEADS 
OLIVELLA Disk BEADS 
The common olivella abalorio of the Channel was about 4 mm. 
diameter, somewhat curved in plane, with edge trimmed round and a 
central hole averaging perhaps 1.75 mm. diameter. These disks were 
prepared from the shell of the olivella and were manufactured in 
enormous quantities. The specimens taken vary in size from 3 mm. 
diameter up to 8 mm. diameter. (PI. 26, 2.) 
OLIVELLA Lip BEADS 
These are made of the entire lip portion of the last whorl of the 
olivella. They also vary greatly in size. (Pl. 26, ¢.) 
MINUTE OLIVELLA Disk BEADS 
Ring-shaped olivella disk beads, with relatively large hole, because 
of their size, and neatly trimmed outer edge, were also found widely 
scattered. The diameter is only about 2 or 2.25 mm. (PI. 26, A.) 
PINK Disk BEADS 
These resemble the common disk beads but are prepared from the 
rock-oyster. They measure about 4.5 mm. diameter. 
Brack Disk Braps 
Disk beads prepared from the mussel shell vary in diameter from 
3to6mm. They have the typical shape. 
ABALONE Disk BEADS 
Abalone disk beads 4.5 mm. diameter, resembling the ordinary disk 
beads in every other way, were found very sparsely. 
THIN CLAMSHELL Disk BEADS 
Disks of clamshell of button-like appearance were also a scarce 
article in the diggings and screenings. These varied in diameter from 
3.5 to 10 mm. An example is shown in Plate 26, a.
