Abstract
The remains of Mammalia from Eocene beds below the Binstead, Gypseous, and Headon or Hordwell series have hitherto been very scanty, and for the most part fragmentary; whether from the clays of London and Bracldesham, or from the equivalent sands, conglomerates, or “calcaires grossiers” of the Continent. The best evidence of Pachynolophus —a Lophiodont genus represented by species of small size, characteristic of the conglomerate of Mont Bernon ( Pachynolophus Vismæi , Pomel) and of the “calcaire grossier” of Nanterre, Passy, and Vaugirard ( Pachynolophus Duvalii , Pomel),—consists of portions of upper and lower jaws, with teeth. The Dichobune suillum , Gervais, from the “calcaire grossier” of Passy, if it be a true Dichobune , rests upon a fragment of mandible with three teeth, and on a few detached teeth, with an astragalus. The genus Propalæotherium , Gervais ( Palæotherium isselanum and Pal. aurelianum , Cuv.), is represented by similar fragmentary evidences of jaws and teeth from the lacustrine calcareous deposits at Buchsweiler, on the Lower Rhine, at Issel in the department of Aude, and at Argenton. The fossil eocene Monkey ( Macacus [Eopithecus] eocænus ) is known only by a small fragment of the under jaw with two teeth, and by a detached mandibular molar from the lower eocene sand of Suffolk. The best and most instructive mammalian fossil hitherto obtained from the London clay has been the portion of cranium with the molar series of teeth on which the genus Hyracotherium was founded. But the subject of the present communication is an entire skull with the complete dentition of both
