DESCRIPTION OF UNGULATA IMP ARIDIG AT AT A. 



Fam. 1. — SOLIPEDIA. 



Gen. AIVCMITMEISIUM, Meyer. 



■ Under the name of Palaeoiheriuni aurelianense, M. De Blainville has inckided 

 also the Falaeotlierium monspessulanum, and the Palaeotherium equinum, Lartet, 

 seu liippoides, De Blainville.^ These, according to the view of M. De Christol, 

 (Comptes Rendus, vol. xxiv., p. 374,) do not belong to the genus Palaeotherium, 

 but to a soliped, to which the name of Hipparitherium is given. In regard to this 

 animal, he observes, " Ses os des membres ressemblent a un tel degre a ceux de 

 I'Ane et du Cheval, qu'on en trouve une description tres etendue et tres-rigoureuse 

 dans les traites d'anatomie v^terinaire, et qu'on peut suivre sur ces os de pretendus 

 Palaeotheriums les descriptions myologiques des veterinaires aussi completement et 

 aussi surement que sur une squelette d'ane ou de cheval." 



H. von Meyer had already placed this species in a new genus under the name of 

 Anchitherium Ezquerrae,^ which generic name is adopted by M. Pomel, in his classi- 

 fication of the Palaeoilieria, as a subgenus.^ 



As a result of these investigations the specific name of the animal is Anchithe- 

 rium aurelianense, Gervais. 



A second species, the Anchitherium Dumasii,'^ has been indicated by Gervais from 

 the eocene formations of France.

Among the fossil remains collected by Mr. Alexander Culbertson were the 

 greater portion of a skull and fragments of jaws with teeth, of a species of Anchi- 

 therium. The teeth of this so closely resemble those represented in De Blainville's 

 Osteographie, under the name of Palaeotherium hippoides, that they might readily
