15. _Tourner’s, Glades County._—In the U. S. National Museum (No. 8088) is a part of a tooth of _Elephas columbi_ sent by J. M. Purvis, Tourner’s, Florida. It was reported as having been collected on the Caloosahatchee River at the place named. This place (spelled also Turner’s) appears to be near Thompson’s and probably in township 43 south, range 29 east. This tooth appears to be the penultimate milk molar; there are 9 ridge-plates in a 100–mm. line. The enamel is thin and much folded.
Leidy (Trans. Wagner Inst., vol. II, p. 23) recorded the discovery of a last molar tooth of _E. columbi_ at some point on the river mentioned. The tooth is in the Academy of Natural Sciences of Philadelphia. Dall (Bull. 84, U. S. Geol. Surv., p. 129) on the authority of Leidy stated that _Bison latifrons_ and _Equus fraternus_ had been found in the Pliocene beds along this river. It is probable that he used _B. latifrons_ in a wide sense. Sellards (8th Rep., p. 102) shows that at least the elephant and the horse were from the Pleistocene.
19. _Palm Beach, Palm Beach County._—Sellards, in his Eighth Annual Report, page 105, stated that there had been secured from the Palm Beach Canal for the drainage of the Everglades, teeth of _Elephas columbi_, as well as those of _Equus complicatus_ and _Mammut americanum_, and a femur of a species of _Bison_.
1. _Bigbone Lick, Boone County._—In the Academy of Natural Sciences at Philadelphia the writer has seen a number of teeth which belong to _Elephas columbi_, found at Bigbone Lick. Whether or not these are part of the collection given by President Thomas Jefferson the writer has not learned. One of these teeth has been described and figured by the writer (Geol. Surv. Indiana, vol. XXXVI, p. 737, plate XXII, fig. 1). It is identified as the upper hindermost milk molar, is wholly unworn, and shows well the form of the crown before it came into action. In that stage the roots are almost wholly undeveloped. The length taken at right angles with the plates is 145 mm. For remarks on the geology of this locality and a list of the species of vertebrates the reader is referred to pages 401 to 404.
2. _Mouth of Big Twin Creek, Owen County._—In the American Museum of Natural History are two fine teeth and a lower jaw, with the ascending rami missing, found where the creek opens into Kentucky River. From the finders, Mr. H. B. Ogden and his son, the writer learned that the jaw was about on a level with the water. They had fastened their boat to it, thinking it was a stump. The top of the bluff was about 35 feet above the water. Some other bones were secured, among them a humerus. The bones were in a mixture of what Mr. Ogden called hardpan and sand. No certain statements can be made about the geological age of this specimen. It might well be pre-Wisconsin.
