720 The American Naturalist. [August, 
have been the most staple articles of diet. In addition toa 
number of small fragments unidentified, were found bones of 
the alligator, of the raccoon, of the turtle, of the black bear, 
of the red lynx (a jaw), of the catfish and of the gar. Also a 
curious bone identified by Professor Cope as supporting the 
dorsal fin in a member of the sheep’s head ifamily. "The jaw 
of the red lynx, an animal hitherto unreported in the shell 
heaps of the St. John's, was submitted to Professor Cope for 
identification. 
Note A. 
Perforated Fulgurs. 
The Prol sometimes termed the busycon, popularly known 
as the conch, was a shell extensively in use among the abo- 
rigines. If specimens of the two species of fulgur most com- 
monly found on the St. John's River are held facing the inves- 
tigator the shell having the aperture to his right is termed 
carica, to his left, perversum. Fulgurs with artificially ground 
beaks and with circular or oval perforations evenly made are 
comparatively numerous upon the surface of the territory bor- 
dering the St. John’s River. They are seldom at a greater 
depth in the shell heaps than can be reached by the plow. 
Their superficial position was noticed and commented upon 
by Wyman (Fresh Water Shell Mounds of the St. John's 
River, Florida, page 58 and Plate VIII, Fig. 2. They are, 
however, occasionally found in the burial mounds of sand at 
depths excluding the idea of an intrusive deposit With the 
exception of Mulberry Mound, no shell heap in the writer’s 
t Wyman figures two perforated objects from the shell heaps, and the 
writer has a considerable number of the phalanges of the deer perforated 
longitudinally, ploughed up and presented to him by Mr. Charles Dillard 
of Volusia. He is also indebted to Mr. McAllister of Bluffton, Volusia Co., 
for the fossil tooth of a shark, perforated — found superficially in 
the shell deposit at that place. 
5 This is particularly true of the great mound at Mt. Royal, Putnam Co., 
. where in one trench among a number made, no less than 1307 fulgurs were 
found by the writer. A very small percentage, however, were evenly per- 
forated in the manner of the shells under discussion. The great majority 
were of the species perversum. Some were unbroken, but the greater num- 
ber were apparently intentionally mutilated in the manner of mortuary 
pottery by having a piece roughly knocked out.
