THE GEOLOGIST. 



;hese 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 Canis, 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 generically 

 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 intermedins. The transversal tooth 

 answers a complete specimen which I know to have come from the 

 freshwater limestone of Kirchberg, near Ulm ; 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 intermedins, found 

 in the brown coal of Kbpfnach (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 supeYieur," 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 Easin.
