Excerpt from The Annals and Magazine of Natural History, Vol. 8: Including Zoology, Botany, and Geology; Being a Continuation of the 'Magazine of Botany and Zoology, ' and of Loudon and Charlesworth's 'Magazine of Natural History' I. - Description of some Molar Teeth from the Eocene Sand at Kyson in Suffolk, indicative of a new Species of Hyracotherium (Hyr. Cuniculus). By Richard Owen, Esq., F.R.S., &c. In the Eocene sand underlying the red crag at Kingston or Kyson in Suffolk, from which the remains of Quadrumana, Chiroptera, and Marsupialia have already been obtained, Mr. Colchester, the discoverer of those mammalian remains, has recently transmitted to me through my friend Mr. Lyell a second collection of fossils, including the teeth of small mammalian animals, some of which are referable to the small Pachydermal extinct genus Hyracotherium, established on a nearly entire cranium obtained by Mr. Richardson from the London clay near Heme Bay, in 1839. The teeth from Kyson are three true molars and one of the false molars, all belonging to the upper jaw. The crowns of the true molars present the same shortness in vertical extent, the same inequilateral, four-sided, transverse section, and nearly the same structure, as in Hyracotherium leporinum; the grinding surface being raised into four obtuse pyramidal cusps, and surrounded by a well-developed ridge, produced at the anterior and outer angle of the crown into a fifth small cusp. These teeth are, however, of smaller size, as will be seen by the subjoined figures of a corresponding molar from the Hyrac. leporinum, fig. 1, and Hyrac. Cuniculus, fig. 2.
