588 Researches in Fossil Zoology. 



I examined the great canine [Reisszahn] of the upper jaw, 

 which indicates a remarkable transition from Felis to Hyena. 

 I call the animal Harpagodon maximus. Thin and long cor- 

 ner teeth indicate a smaller carnivorous animal. Beyond 

 the grinders some of them are very singular with respect to 

 their fangs [Kronen], which are formed in a carnivorous 

 shape, and the roots, from their swollen appearante, resem- 

 ble the teeth of a certain phoxen ; but in comparison with 

 them these fossil teeth are of an immense size. 



Many undetermined bones have been found in it, which 

 seem to have been taken from the head of an enormous ani- 

 mal. On the surface are some furrows, similar to the impres- 

 sions of the mailed coat turtle [Scheldhroten Panzer], on 

 which are bound two shields of exterior covering, but it is not 

 known if the skulls of turtles have had such impressions of 

 their boundaries, [Grenzeindruhen]. If this bone have been 

 taken from a turtle, it would prove to be an animal of the same 

 size as those fossil remains discovered in the Sivvalix moun- 

 tains in India, called Megalochelys. These layers of Bohn- 

 erz and molasse of the Suabian Alps contain besides numer- 

 ous remains of fish, which indicate the tertiary formation. — 

 By the agreement of these fish and Mammalia, I came to 

 the result that the tertiary lime in the Rhenish basin near 

 Mayence, the tertiary sandstone and sand, to which belong 

 the very rich fossil formations of Eppelsheim and Flersheim, 

 and the Bohnerz and molasse formation in Suabia and Swit- 

 zerland, are only the different localities of a vast superficial 

 tertiary formation, which extends over a great part of the 

 European continent, and perhaps may also be met with in 

 other parts of the world, as in Asia and America, especially 

 in the basin of the Pampas. 



The tertiary gypsum from Hohenhoven contained besides 

 the Testudo antiqua, the remains of a large and small rumi- 

 nating animal, as well as those of a large pachyderm. 



I have illustrated these examinations by figures and copies 

 of the originals, by a certain method which, without injuring 

 the picturesque effect, represents the objects in such a manner 

 that we are able to measure them with the compass.
