3. _Yarnallton, Fayette County._—From Professor Miller there was received with the specimen above described pieces of the jaws of _Tapirus haysii_, discovered in an old stream-deposit at the place named. A fragment of a lower jaw was sent; also a piece of a right maxilla, with the anterior true molar complete and parts of the second molar and of the hindermost premolar. Some other parts of the skeleton were found, but they seem not to have been cared for. FINDS OF RHINOCEROSES IN EASTERN NORTH AMERICA. FLORIDA. 1. _Archer, Alachua County._—Two species of rhinoceros have been described from this locality. In 1884 (Proc. Acad. Nat. Sci. Phila., p. 118), Dr. Joseph Leidy reported the discovery, with other fossils, of remains of a species of the genus _Rhinoceros_ in Alachua clays, but he gave it no name. This was, however, done in 1885 (same Proceedings, 1885, p. 32). In 1896, after the death of Leidy, his unfinished paper, completed and edited by Professor F. A. Lucas, was published (Trans. Wagner Free Inst. Sci., vol. IV, p. 41 seq., with numerous figures). This species is now referred to _Teleoceras_, as _Teleoceras proterus_. In 1890 (Proc. Acad. Nat. Sci. Phila., 1890, p. 94), Leidy described another species which he called _Rhinoceros longipes_, from the same place and deposit. This species is now called _Aphelops longipes_. These species are usually credited to the Upper Miocene or Lower Pliocene. The reader is referred to page 376, where the geological position of these beds is discussed. 2. _Williston, Levy County._—In his list of 1892 (Bull. U. S. Geol. Surv., No. 84, p. 129), furnished by Leidy, W. H. Dall included _Rhinoceros proterus_ among the fossils found at Mixon’s, near the village of Williston. 3. _Dunnellon, Marion County._—In 1913 (5th Ann. Rep. Florida Geol. Surv., p. 58), Dr. E. H. Sellards stated that some remains of a rhinoceros had been found in the mines worked along Withlacoochee River, in the region about Dunnellon. In volume VIII of the Florida Survey, page 94, _Aphelops malacorhinus_ (=_A. longipes_) is included among the fossils found in the Dunnellon formation. It is not included in his list of Pleistocene species found in the Withlacoochee River (Florida Geol. Surv., vol. VIII, p. 104). This was doubtless because he regarded it as belonging to an earlier formation. 4. _Mulberry, Polk County._—In 1915 (7th Ann. Rep. Florida Geol. Surv., p. 72), Sellards stated that a tooth of _Teleoceras fossiger_ (in the present work recognized as _T. proterus_) had been discovered in the Bone Valley phosphate formation, at the place named. As in other cases, the Bone Valley formation was referred to the Late Tertiary.
