92 FLORIDA GEOLOGICAL SURVEY-TWELFTH ANNUAL REPORT 
570 and 580 feet. Entirely composed of entire and partly broken specimens 
of Laganum (?) crustuloides (Morton). 
590 feet. Mixture of various things from above. 
600 feet. Similar to 570 and 580. 
620-632 feet. Orbitolina mixed with things from higher levels. 
640-770 feet. Abundant Orbitolina alone. 
DISCREPANCIES IN THE RECORD. 
In the thick series in the Ocala at 410 feet occur abundant thick 
Nummulites after 40 feet of the Ocala. This becomes less in the 
sample from 420 fe.et and then does not reappear in quantity until 
535 and 540 feet, where the same species occurs. This resembles 
a species found in the Upper Eocene of Northern Florida and 
Southern Alabama apparently occurring just below the Ocala. If 
this is correct the Ocala would be limited to the section from 360 
to 400 feet and 40 feet thick, the other material below to 632 feet 
having fallen down or been drawn up from this section. This 
suggestion is here noted for further reference. It may be noted 
in addition that the material is almost entirely of very coarse frag¬ 
ments or whole specimens from 450 to 530 feet, showing compar¬ 
atively little effect of the drill. The material at 550 feet is finely 
cut by the drill and consists largely of the debris of the echinoid 
noted. At 570, 580 and 600 feet the samples are almost entirely 
made up of whole or only partially broken specimens of this spe¬ 
cies. These are too large to have well escaped the drill and with 
lack of fine, material would seem to be material drawn from the 
sides of the well from 400 feet or above rather than from the vari¬ 
ous depths below. This is even more strongly indicated by the oc¬ 
currence with them of numerous specimens of Orbitolina charac¬ 
teristic of the Lower Cretaceous and found in abundance alone in 
the samples below. It is still more strongly indicated by the oc¬ 
currence at 590, 620, 623, 632 fe.et of a mixed material contain¬ 
ing Lepidocyclina, Nummulites and Orbitolina and very evidently 
in large part formed of material derived from above 400 feet. 
PROBABLE STRATIGRAPHY. 
Below 350 feet there is indicated at least 40 feet of Ocala 
Limestone equivalent to that found about Ocala. At 410 feet is
