718 The American Naturalist. [August, 
but giving evidence of wear upon the edge, and having a por- 
tion of the shell between the ridges removed. A pecten, with- 
out wear or work upon the edges, is figured in the annual 
report of the Bureau of Ethnology, 1880-1881, Plate XXI, 
Fig. 3. This particular shell is described as having served 
among the Indians as a receptacle for paint, and as coming 
from Santa Barbara, California. It is possible that the “ cockle 
shell” from Mulberry Mound may have been used for the lin- 
ing of pottery. At all events, the two central ridges could be 
put to such a purpose. 
At a depth of 13 feet, 8 inches was found a portion of a 
gorget of shell, the part recovered being 6.04 inches in length, 
2 inches in breadth, with an average thickness of .12 inch 
(Fig. 14). It bore three perforations for suspension or for 
attachment, and two smaller ones along the line of fracture, 
evidently corresponding with similar ones on the missing por- 
tion, arranged to allow of repair by binding, a method com- 
mon at that period. The discovery of a gorget or any object 
of personal ornamentation is so unusual in a shell heap of the 
St. John's that particular stress deserves to be laid upon it. 
In fact, with the exception of one longitudinally perforated 
phalanx of a deer, from Salt Run (Marion Co.), no articles of 
personal adornment have been found by the writer in any 
shell heap of the St. John's beyond the limits of Mulberry 
Mound.* 
At various distances from surface, one even so deep as 11 
feet, were found six fulgurs, five of the species carica and one 
perversum. All were ground at the beak, and all with the 
exception of one carica, were perforated. Three of the spe- 
cies carica had single perforations below the angle and involv- 
ing it, and one on the body whorl between the angle and the 
suture within an inch of the aperture. 
The fulgur perversum had a small round perforation above . 
the angle and two, one 1 inch, the other i inch, below. These 
perforations were considerably larger than the one above. 
‘The finding of the perforated fulgurs at so great a depth in a 
shell heap will, with other matters relating to these perforated - 
shells, be referred to in Note A.
