468 NOTES ON THE ТЕХ THOUSAND ISLANDS. FLORIDA. 
for attachment were not made above the shoulder, they were dispensed with, though 
in a few cases they are found in the body of the shell. A small number of such 
instances have come to our notice, and there is in our collection at the Academy of 
Natural Sciences a good example from Fikahatchee Key, where a shell with a fine 
| gouge edge, апа а hole and a notch to accommo- 
date a handle, has a small, round perforation in 
the body-whorl—too small to have served for any 
purpose except for the passage of a thong. 
Two shells (Fuleur perversum) added to our 
collection since the last report, differ from ordinary 
types in that while both have edges beautifully 
ground at the beaks, and each has a part of the 
body-whorl cut back from the aperture, neither 
shell bears hole or notch for the accommodation 
of a handle. One implement, however, has a hole 
for attachment above the shoulder of the shell, 
while the other is without one. These implements 
came respectively from Little Marco and the 
Crawford Place, below Naples. 
As to another class of shells we are unable ав 
yet to reach а decision. These shells, sparingly 
found on the Ten Thousand Islands, were fairly 
numerous on Wason, or Cora Key, in Pine Island 
Sound, north of the Ten Thousand Islands. The 
shells (Fulgur perversum) are carefully cut back 
from the aperture as if for use as tools and have - 
above the shoulder usually one small hole, but 
P sometimes two, for attachment. In certain cases 
"19.24. 81 іштіетелі. Losman’ Key. some of these holes seem to bear evidence of wear. 
On the other hand, in no instance do these shells 
have any hole or notch through which a handle may be passed. The beaks are 
considerably chipped as if by use, but above the splintered part is no sign of the 
remainder of the ground surface, which is so often apparent on other tools, though 
they have been subjected to prolonged use. It is possible these shells were used as 
tools with the aid of a handle abutting against the inside of the body-whorl, the 
thong extending over the outside of the shell. Presumably the beaks were not 
ground prior to use, the implements serving as picks with unground beaks, as was 
the case with the large “ horse-conchs " (Fasczolaria), one of which is shown in this 
report (Fig. 21). 
On all the shell keys, and notably on Fikahatchee Key, we found masses of 
sandstone, smoothed and furrowed by use. "These stones, we believe, were those 
used in conferring cutting edges on the shell tools of the keys.
