1. Rockcastle County.—In 1853, Dr. Leidy (Trans. Amer. Philos. Soc., vol. X, p. 331, plates XXXV, XXXVI, XXXVII, figs. 5–8, 17, 19) described under the name Euchœrus macrops, a fine skull of a peccary which had been lying for 47 years in the collection of the society. It had been sent there by Dr. Samuel Brown, of Lexington, Kentucky, and was said to have been found in one of the nitrous caves of that State. The writer is informed by Dr. Arthur M. Miller, Professor of Geology in the University of Kentucky, that it is unlikely that the skull came from any of the caves in the region about Lexington, as he had never heard any of them had been worked for saltpeter. In the Transactions of the American Philosophical Society for 1804 (vol. VI, pp. 235–247) is a paper by Samuel Brown, in which he describes a cave in what is now Rockcastle County. In this and some other neighboring caves were found immense quantities of saltpeter. Probably the skull which Leidy afterward described from this region was brought to light. It appears to have been mentioned by Dr. B. S. Barton as early as 1806 (Phila. Med. and Phys. Jour., vol. II, plate I, p. 158). It is now in the collection of the Academy of Natural Sciences at Philadelphia. It was recognized by Leidy as belonging to Platygonus compressus.
