500 THE GEOLOGIST. ^ 
these circumstances, the following constitution of the dental system of 
the Carnivore whose remains are found in the fresh-water limestone of 
Tuchoritz may be inferred. Incisors very much flattened, without 
superior apophysis, the outer upper ones canine-like ; canines strong, 
moderately incurved, of oval transverse section, each with two strong 
vertical ridges ; Pre-laniaries very high, number unknown ; Laniaries, 
especially the upper ones, comparatively small, of evidently omni- 
vorous character in both jaws ; Upper Molars more than two, the last 
one rooted ; of the Lower Molars the last or penultimate, with single 
root, is only known. 
All these characters concur in denoting a geuus of the Canidce less 
carnivorous than the typical genus CaniSj and even less so than any 
other form of the Tertiary genus Amphicyon as made known by 
Blainville. Notwithstanding certain analogies with Otocyon, the least 
carnivorous genus of living Canidce , there is no reason for genericallj 
separating the form here in question from Amphicyon. 
None of the species established either on Blainville's figures nor on 
generally rather incomplete remains found in Tertiary deposits being 
found to agree completely with the specimens from Tuchoritz, I thought 
proper to consult M. H. v. Meyer, who had previously described some 
species of Amphicyon from the Tertiaries of S. Germany. This dis- 
tinguished Palaeontologist answered me kindly in the following words : 
" The species whose teeth you were pleased to send to me in figures, I 
think to belong to my Amphicyon inter medius. The transversal tooth 
answers a complete specimen which I know to have come from the 
freshwater limestone of Kirchberg, near Ulm j not quite complete 
specimens of upper and lower laniaries, and outer upper incisor from 
the Molasse of Ermingen and Heppbach, are only different from their 
somewhat larger size ; they answer still better to incomplete teeth, in 
fragments of upper and lower jaws of Amphicyon inlermedius, found 
in the brown coal of Kopfnach (Switzerland), and probably also in 
the Molasse of Giinzburg." 
Remains of Amphicyon, so far as is known at present, have ex- 
clusively been found in deposits ranking among M. Lartet's " Miocene 
moyen," and "Miocene superieur," perhaps even only in the first of 
them. As far as I know, they have not yet been met with in the 
strictly so-called Vienna Basin.
