Lower Jaw. This contains six molars, and is from the same locality. Size, 11 x 6. Price, $ No. 104. Lophiodon Parisiense, Gerv. Lower Jaw. This tapiroid Mammal, the Tapirotlierium of De Blainville, is known only by imperfect fragments, though Cuvier established the genus so early as 1800. It has the same dental formula as the Tapir; but the premolars present a more simple structure, the lower series having the crown compressed and forming two cones, and the last two in the upper jaw having only one'cone on the inner side. This jaw was found in the calcaire grossier (Middle Eocene) near Paris, and is in the Garden of Plants. Size, 13 x 6. Price, $ No. 105. PliolopllUS VUlpicepS, Owen. Skull and Lower Jaw. This odd-toed, hoofed Herbivore stood intermediate between the Tapir and Palasotherium. The skull has a straight upper contour like that of the Horse ; while that of the Palaeotherium and Anoplo- theriurn is convex. As in the Hog and Palaeo- therium, the greatest cerebral expansion is at the middle and toward the fore-part of the temporal fossa?, with a contraction toward the occiput. The orbit is higher than in the Rhinoceros, and lower than in the Hog. The dentition is like that of nearly all Eocene quadrupeds, a type not ex- hibited by any later or existing Mammal, namely: three incisors, one canine, four premolars, and three molars in each ramus. This interesting fossil was dis- covered in the London Clay (Eocene) of England, and is now in the British Mu- seum. Price, $ No. 106. Palaeothermm crassum, Cuv. Head. The dis- covery of the P.—one of the most character- istic Mammals of the Tertiary world—form- ed an epoch in the his- tory of fossils. The creature resembled the Tapir in the shape of the head and the possession of a short proboscis; but it h
