Felsach to the Imperial Museum is a left upper jaw, from a young 

 individual just changing its teeth ; a remarkable specimen, as almost 

 proving the identity of Hycena Hipparionum, Gerv., with H, eximia, 

 Both, and Wagn., and admitting a more accurate comparison of this 

 species with Hycena spelcea and their living congeners. 



The individual first described by M. Gervais (Zool. Pal. Franc, 

 p. 121, pi. xii., f. 1) differs from the Pikermi specimen only by being 

 less in size ; another individual (loc. cit. pi. xxiv., f. 2-5), described by 

 him as being " equal in size to Hyama spelcea, and H. crocuta" leaves 

 no doubt as to the specific identity between the individuals of 

 Pikermi and Cucuron (Dept. de Vaucluse) ; affording at the same 

 time an argument for the diffusion of this species over the whole 

 of Middle Europe. 



The tubercular tooth of H. Hipparionum surpasses in size those of 

 any other living or extinct congener ; and the shape of the root sug- 

 gesting the presence of an independent apophysis on the posterior 

 portion (somewhat damaged in our specimen), the form of the fossil 

 tooth stood next to the tubercular tooth of young individuals of the 

 living H. fusca. There are still other analogies with the dentary 

 system of young individuals of living species. 



Amphicyon intermedins, H. v. Meyer. 



The fresh- water limestone of Tuchoritz (Bohemia), first described by 

 Professor Reuss [Vienna Imp. Academy Proc, 1860, vol. xlii., p. 56), 

 contains a certain number of Mammalian remains, among which, be- 

 sides those of Rhinoceros or Acerotherium, of Chcerotherium Sansas- 

 niense, Lart. (Sus Chmrotherium, Blainv.), and Palmomeryx Scheuchzeri, 

 H. v. M., mixed with some few impressions of leaves (Diospyro- 

 brachysepala, A. Br., and Leguminosites Proserpince [?], Heer), Pro- 

 fessor Suess has recognised eighteen loose teeth, entire or fragmentary, 

 belonging to one and the same individual of a large carnivorous 

 mammal. 



The laniary tooth of the left lower jaw, quite different from the 

 analogous teeth in the genera Felis, Hycena, and Ursus, belongs evi- 

 dently to an animal of the family Canidoz, evidently of more omnivorous 

 habits than any other of this family, and larger in size than Canis 

 Neschersensis, Can. Issiodorensis, or any other fossil species immediately 

 referable to the genus Amphicyon, Blainv. 



The laniary tooth of the upper left jaw, far inferior in size to the 

 same tooth in the Wolf, and of a more omnivorous character, next 

 resembling Amphicyon minor, Blainv. (Tab. xvi.) 



The fragments of molar teeth, minute and incomplete as they are, 

 prove the existence of at least three molar teeth (one more than in 

 the genus Canis), of which the third or hindmost is provided only 

 with one root. The incisive teeth resemble those of Amphicyon as 

 figured by Blainville ; one of them shows conspicuously the com- 

 pressed and flattened shape characteristic of this genus. From all
