Researches in Fossil Zoology. 585 



the last milk tooth from the left lower jaw of a ruminant, 

 scarcely the size of a roebuck ; and the structure of this 

 tooth differs very much from both the recent and extinct ru- 

 minating animals of the diluvial strata. This tooth is of the 

 same shape as of those ruminants which I have called alto- 

 gether Palacomeryx. The same sort of tooth T examined in 

 the Bohnerzablagerung of Mosskirch. In the molasse of 

 Stein were moreover found the tooth of a large Saurus ; the 

 seventh edge-plate of the mailed back turtle, [Ruckenpanzer]; 

 the fourth rand-plate of the mailed belly turtle, [Bauchpan- 

 zer], resembling the type of the testudo-formed turtle; and 

 the femora of a bird resembling the domestic fowl. 



From the finer molasse-sandstone at Seelmatte has been tak- 

 en the lower grinder, as it has hitherto been considered, of 

 the Palacother him, but it belongs to the Rhinoceros incisivus; 

 and from the brown coal [braunkohln] of Seehatten has been 

 produced a sharp edged tooth [Schneiderzahn], which indi- 

 cates a certain pachyderm. From the brown coal near Greit, 

 on the northern declivity of the Haute Rhone, near the vil- 

 lage of Meinzingen, only the remains of the Rhinoceros Gold- 

 fussii are known to me. 



The layers of the pitch coal of Kapfnaden and Elgg are 

 very celebrated for the many fossil bones they contain. Near 

 Kapfnaden have been found the most numerous remains of 

 Mastodon angastidens, and also a rodent. From the upper 

 jaw of the Mastodon angustidens I examined the first grinder, 

 which has two indentations, and the fourth grinder has three ; 

 then in the lower jaw the fourth grinder has also three inden- 

 tations, to which a piece of the fifth grinder is attached. I 

 also examined the remains of the gnawing teeth of at least 

 fourteen individuals of the rodent, and ascertained the form 

 of the teeth in the upper and lower jaw-bones, as well as the 

 form of the lower jaw-bone itself. This animal comes very 

 near to the beaver, and I do not find it differs from those in 

 the layers of Eppersheim, known as Chalicomys Jagerii, from 

 the pitch coal of Kapfnach. This coal also contains three 

 genera of ruminating animals, which differ in the structure of 

 their teeth. One of these genera resembles very much our 

 living ruminating species ; another is like those designated 

 by me Palacomeryx ; and the third is quite new : I call it 

 Ozygotherium Escherii. Each of these three genera has six 

 grinders in the lower half of their jaw-bones. 



The pit coal near Elgg contains quite different animals. — 

 A peculiar species of Mastodon is often found here, the Mas- 

 todon Luricense ; of which I examined the milk tooth of the 

 upper jaw, and the corresponding tooth of the first grinder,
