Discussion.
Prof. Duncan remarked that the presence of Sivatherium and Hyænarctos in Spain, if confirmed, would be particularly interesting, as showing a great western extension of the Sivalik fauna. He suggested that there was an error in the statement that Elephas armeniacus occurred in the valley of Madrid, and thought that the species would prove to be E. africanus. He also suggested that E. armeniacus was not really a distinct species, but that it and E. namadicus were merely local forms of E. antiquus.
Prof. Busk said that most of the animals the bones of which are so numerous at Gibraltar appear to have migrated from the south. He thought that there was probably some mistake as to the species of Elephants, and doubted whether remains of the Mammoth had ever occurred in Spain. He added that the bone which had been thought to belong to Sivatherium was an astragalus, and that it was chiefly, he thought, on account of its size that Dr. Falconer suggested such an identification.
Mr. Charlesworth stated that he had obtained from the Crag a tooth which had been pronounced by Mr. W. Davies, of the British Museum, to come nearest to that of Hyænarctos among known Mammalia, and remarked that this seemed to confirm the extension westward of that type of animals.
Dr. A. Leith Adams stated that molars of Elephas primigenius from caves in the zinc-mines at Santander had been brought to his notice. He doubted whether E. africanus had been found fossil. Dr. Falconer finally regarded Elephas priscus as a variety of E. antiquus. Many teeth, with thick plates, were found in the caves of Palermo; and these were clearly of E. antiquus; the Spanish specimens required confirmation. He confirmed the President's suggestion that Elephas namadicus was identical with E. antiquus.
Dr. Murie was doubtful about the identification of the fossil supposed to indicate Sivatherium, The specimen nor being a bone of the head, there was a great chance of error.
