Researches in Fossil Zoology. 587 



posed to be the Anoplotherium or Cheropotamus ; and the 

 fragments of a lower jaw-bone, which I determined by a draw- 

 ing of M. Meissner to be his peculiar species, Cheropotamus 

 Meissneri ; but I shall further examine this fossil. 



The molasse sandstone of Maggenwyl near Lenzburg is 

 also very interesting ; the collection at Zurich contains some 

 teeth of the Rhinoceros incisivus. 



Tn the collection of the Prince of Furstenberg at Donan- 

 schwingen, are preserved the fossil bones found in the tertiary 

 Bohnerz formation of Mosskirch. I am now occupied with 

 their examination. Rhinoceros incisivus, accompanied by the 

 larger Rhin. Goldfussii, and a smaller species, are very fre- 

 quent in it. The remains of the Mastodon angustidens, next 

 to those of the Rhinoceros, appear to be most numerous ; the 

 teeth also of the saurians seem to be frequent. There are 

 likewise different species of a kind of stag, the teeth of which 

 in their structure seem to agree with Palacomeryx, and one 

 among them similar to living ruminating animals. Further- 

 more there have been found the remains of an animal resem- 

 bling a pig, and two species of Dinotherium, one of which 

 resembles the Din. Bavaricum, the other of a genuiue tapir, 

 and Palecotfierium crassum. 



Different carnivorous animals are also imbedded in the 

 Bohnerz. Those found in the tertiary formation offer many 

 peculiarities, and much that is new is confirmed by these re- 

 mains. From the new genus, which seems to be the largest 

 of all the known carnivorous animals taken from it ; by the 

 collection at Berne it is also seen that land Mammalia have 

 been buried in it, but it seems still that aquatic Mammalia 

 were more frequent. I saw moreover the right half of the 

 upper jaw of an animal which bears some comparison with 

 Manatus ; this will be explained by me under the name Ma- 

 nutus Studeri. In the Jura of Switzerland are also to be 

 found tertiary formations with bones in them. At the meet- 

 ing of the Professors of Natural History at Neufchatel, in 

 July, 1837, I was shown a tooth from the pit coal of Lock, 

 which is subordinate to the freshwater limestone, but is situ- 

 ated above the marine molasse ; this tooth I recognised as 

 the principal grinder of the Dinotherium giganteum. 



I am also occupied with the fossil bones of the Bohnerz 

 formation, and the molasse of the Suabian Alps. At Professor 

 Fleischer's I saw a human tooth at Aaran, taken from the 

 Bohnerz ; it is the last grinder but one of the right side of the 

 lower jaw. Its condition, shape, and quality agree with those 

 teeth found at the same time, and which are all from extinct 

 genera, and belong to the tertiary period.
