MEMOIRS OF THE CARNEGIE MUSEUM. 
Chey were without doubt ungainly plantigrades, capable of using their anterior feet 
for scraping and grasping. 
Their geological distribution extends from the upper Eocene to the Pliocene. 
Schizotherium Gervais (Zool. and Paléont. Gén. IJ, p. 58). The genus was founded 
upon the phalanges and metapodials of a small Chalicothere from the phosphorites of 
Querey. (Schiz. priscum Gaudry, sp.) In the same deposits are found teeth which 
were described by Gaudry as Chalicotherium modicum, but which in all probability 
belong to the same species. 
? Pernatherium Gervais (Journal de Zoologie, V, p. 424). Only a caleaneum, a 
metatarsal, and a few fragments of other bones exist. Eocene (Calcaire de St. Ouen), 
Paris. 
? Limognitherium Filhol (Compt. Rendus Hebd. 1880, p. 1580). Only large meta- 
carpals about 0.18 m. in length are known. Upper Eocene. (Quercy Phosphorites).

PR: 3) M. 3° Skull with a weak sagittal crest, the parietals converging, not flattened, 
frontals bordering the orbits which are only partially surrounded by a bony ring. 
The occipital condyles moderately produced and on the under side of the skull 
extended somewhat forward. Auditory bulle strongly inflated, having the form of 
a bent cylinder. The mastoid process strongly developed. The mandible very high, 
straight on its lower edge, like Palewosyops, the hind margin of the ascending ramus 
without a forward projection. Upper incisors and canines are not known. The 
molar series increasing in size posteriorly. The breadth of the three upper pre- 
molars exceeds their length; the outer wall of the two anterior premolars shows one 
cusp, P* two cusps; on the inner side all the premolars have but one large inner cusp, 
which sends forth behind to the outer wall a erescentic ridge. The three molars 
are quadrate with a W-shaped outer border, a large anterior and a small posterior 
inner cusp. The mandible has three incisors and a canine, which are closely grouped 
together. The last premolar and the molars of the lower jaw consist of two bluntly 
curved crescents, which unite on the inner side in two separate, slightly thickened 
points. P; has one somewhat lengthened and compressed sharpened cusp. Middle 
Miocene of Sansan (Gers), Bon Repos and St. Gaudens (Haute Garonne), Grive-Saint- 
Alban (Isére), Haeder in Southern Bavaria and Steinheim, Wiirttemberg (M. grande 
Lartet); also in the lower Miocene in the neighborhood of Ulm (M. [Chalicotherium|] 
Wetzlert Kowalewsky). 
At Sansan and Grive-Saint-Alban there were found skeletal remains, which were 
originally described as Macrotherium sansaniense Lartet, but which according to Filhol 
and Depéret undoubtedly must be regarded as remains of the skull and teeth of 
Anisodon Lartet. The bones of the feet possess essentially the same characteristics
