Gervais, loc. cit. 2nd ed. pi. xv. fig. 4, which was obtained from the Upper Eocene of St. Gely-du-Eesc, near Montpellier (Herault), Erance. The specimen noticed below agrees so closely with the type, that it may be at least provisionally referred to the same species. Hah. Erance. M. 1419. The left ramus of the mandible, containing all the cheek- teeth (the last milk-molar being still in position); from the Upper Eocene of Caylux (Tarn-et-Garonne), Erance. This specimen, which is represented in the accompanying woodcut (fig. 24), from the very elongated form of the Fig. Xiphodon gelyensis?—The left ramus of the mandible; from the Upper Eocene of Caylux. \. premolars and the apparent absence of a diastema, seems to belong to a true Xiphodon, and is of much smaller size than X. gracilis. The three true molars agree almost exactly with those of the type of X. gelyensis; but the last milk-molar is rather longer than pm. 4- The length of the space occupied by the seven cheek-teeth is 0,061, and that by the three true molars 0,025 ; the latter dimen- sion in the type specimen being 0,0265. The teeth are very like those of X. gracilis. Purchased, 1884. 1 Zool. et Pal. Francaises, 1st ed. vol. i. p. 90 (1848-52)..
