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. 9. _St. Petersburg, Pinellas County._—In the museum of the State University at Gainesville, Florida, is an upper left second molar of _Elephas columbi_ recorded as having been found at Indian Rock, a village near St. Petersburg, in the peninsula west of Tampa Bay. The tooth is covered with barnacles and had evidently been in salt water. No other information was secured respecting the tooth.
