ANTHRACOTIIERIID.i:. 239 



Anthracotherium alsaticum, Cuvier '. 



This smaller species was founded on the lower jaw of a young 

 individual from the Lower Miocene of Alsace, which P. Gervais 2 and 

 De Blainville thought might be included in A. magnum. Subse- 

 quently the palate of an Anthracotherium from the Upper-Eocene 

 phosphorites of France was described and figured by P. Gervais 3 , 

 who thought that it might be referred either to A. alsaticum or 

 A. cuvieri (=A. onoideum), both of which he speaks of as races of 

 A. magnum. Another palate has been described and figured by 

 Filhol 4 from the same formation, which, from its association with a 

 mandible having an external projection (wanting in A. cuvieri), he 

 thought might be referred to the present species. He shows, how- 

 ever, that there is a transition i,n respect of size between the smaller 

 form and A. magnum ; so that it seems rather a question of races 

 than species. Teller 5 is somewhat doubtful of this identification ; 

 but ene of the specimens noticed below (No. M. 2177) indicates its 

 correctness. There seems, indeed, no possible means of distinguish- 

 ing between the upper dentition of A. alsaticum and A. cuvieri; the 

 latter species being distinguished merely by the form of the mandible. 

 Under these circumstances the course here followed has been to pro- 

 visionally refer all the European specimens of Anthracotherium, not 

 showing the characteristic part of the mandible, which are decidedly 

 smaller than the typical A. maynum, and yet larger than A. minus, 

 to the present species or race. In the palate figured by Filhol the 

 upper premolars are in contact, but are separate in the one figured 

 by Gervais. 



Hub. Europe. 



M. 1389. The first left upper true molar ; from the Upper Eocene of 

 Caylux (Tarn-et-Garonne), France. This specimen agrees 

 in size with the corresponding tooth in the palates figured 

 by Filhol and Gorvais. Purchased, 1884. 



M. 2176. Fragment of the right maxilla, containing the last three 

 premolars ; from the Upper Eocene of Caylux. This spe- 

 cimen agrees precisely with the corresponding portion of 

 the palate figured by Filhol. Purchased, 1885.
