4. _Near Mantanzas, St. John County._—At the residence of Fred R. Allen, St. Augustine, Florida, the writer has seen part of four hindermost molars, three upper and one lower, of _Elephas columbi_, found in the Inland Waterway Canal, near his farm, 28 miles south of St. Augustine, apparently not far from Mantanzas. At the same place have been found _Mammut americanum_, _Equus_ sp., _Mylodon harlani_, and _Terrapene antipex_. Sellards (8th Rep. p. 106) adds to this list an undetermined species of _Bison_ and one of _Odocoileus_.
5. _Ocala, Marion County._—From this place Leidy (Trans. Wagner Inst., vol. II, p. 17, plate III, figs. 6–9) has described and figured a first and a second milk molar. The figures have been reproduced by the writer (Iowa Geol. Surv., vol. XXIII, plate LXI, figs. 2, 3, 5, 6). These teeth certainly belong to _Elephas columbi_. They were found in a fissure in a limestone rock, near Ocala, in the property of Mr. F. M. Phillips. With them were a part of a skull of _Smilodon floridanus_, teeth of a horse which Leidy referred to his _Equus fraternus_ (=_E. leidyi_), and teeth supposed to belong to the little camel _Procamelus (Auchenia) minimus_. These fossils were referred to the Pliocene, but apparently there is not sufficient reason for doing so. The geology of the locality is treated on page 378.
6. _Dunnellon, Marion County._—In the collection of the Florida Geological Survey, No. 2232, is a part of the rear of what is regarded as a hindermost upper molar, found in a phosphate mine near Dunnellon. There are 7 ridge-plates, but some are missing from the front and some from the rear. The height of the front plate present is 210 mm.; the width is 82 mm. There are 6 plates in a 100–mm. line. This tooth is remarkable because of its thinness. It is possibly a more anterior tooth, but is rather high to be such.
The geology of the neighborhood of Dunnellon and a list of the species collected there are to be found on page 376.
7. _Holder, Citrus County._—In the collection of Dr. H. G. Bystra, chemist of the Buttgenbach river mine, is a fragment of a tooth of _Elephas columbi_, found in the mine, on Withlacoochee River, a few miles north of Holder, in section 29, township 17 south, range 19 east. In the same collection are a fragment of an upper and one of a lower molar, found in the same place in dredging for phosphate rock.
