3. Citra, Marion County.—In January 1914, the writer saw at Ward’s Establishment, at Rochester, New York, the hinder half of a lower left hindermost molar of Elephas columbi, labeled as found at Citra. No details were preserved respecting the history of the tooth. There were 6 ridge-plates in a 100–mm. line.
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.
21. Sumterville, Sumter County.—In the collection of the Florida Geological Survey (No. 240) is a single plate of a tooth of Elephas columbi, found by Dr. Sellards 3 miles east of Holder.
16. Daytona, Volusia County.—In 1916 (8th Ann. Rep. Florida Geol. Surv., p. 105), Sellards stated that Mr. Morris, of Daytona, had found in a marl pit a tooth of Elephas columbi. As stated on page [122], remains of Mammut americanum have been found in similar pits. In these pits were collected a piece of a tusk of a proboscidean and a rib of a whale, thought to belong to the genus Balænoptera.
In the Fifth Annual Report of the Florida Geological Survey, on pages 222 to 225, are presented the logs of artesian wells put down at Daytona. In one well was found a bed of white marl at a depth of 6 feet, having a thickness of 9 feet. It is possible that this corresponds to the marl-bed which furnished the elephant and whale, and it may belong to the first glacial stage.
8. Tampa, Hillsboro County.—In the collection of Heidelberg University, Tiffin, Ohio, the writer has seen a fragment consisting of two plates of an upper molar of Elephas columbi, labeled as having been found at Tampa.
