Sci. Geol. vol. viii. art. 1, p. 227. The true molars of the present specimen are like those of a primitive ruminant, but the second inner crescent is incompletely developed in m- 2, and in m. 3 is rudimentary. The length of the space occupied by the three true molars is 0,041. Purchased, 1885. Genus DICHODON, Owen1. Dentition :—I. |, C. \, Pm. J, M. |. The upper true molars are perfectly selenodont, with concave outer surfaces somewhat like Hyopotamus; the earlier premolars are elongated, and thereby ap- proach Xiphodon. The limb-bones are unknown. The general form of the dentition is illustrated in the accompanying woodcut (fig. 19). 1 Quart. Journ. Geol. Soc. vol. iv. p. 36 (1848)..
