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 llycena Hijyparionum, Gerv., with H. eximia, 
Roth, 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. Frangy 
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 Hycena spelcea, and H. crocutaP leaves 
no doubt as to the specific identity between the individuals of 
Pikermi and Cucuron (Dept. de Yaucluse) ; 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 inter meditcs, 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 Choirotherium Sansas- 
niense, Lart. {Sm ChcerotJierium, Blainv.), and Palceomeryx Scheuchzeri, 
H. V. M., mixed with some few impressions of leaves (Diospyro- 
hrachysepala, A. Br., and Leguminosiies 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 Canidce, 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 Aiiiphicyon as 
figured by Blainville ; one of them shows conspicuously the com- 
pressed and flattened shape characteristic of this genus. From all
