COLUMELLA BEADS 
Long, tapering white columella beads, with a spiral groove wind- 
ing about the surface, were made in part from the columella of the 
Top-shell, the large, straight-sided univalve that is still seen 
occasionally tossed out on the beaches of the vicinity. Specimens 
illustrating all stages of the process of manufacture were obtained. 
Typical specimens are shown in Plate 26, and o.
