18 EXPLANATION OF PLATE 2. 



PLATE 2. V. 1 p. 64. 



A. Jaw of Didelphys Bucklandi, (Magnified to twice nat. 



size,) in the Collection of W. I. Broderip, Esq. and 

 described by him in the Zoological Journal, V. III. 

 p. 408, PL XI. (Broderip.) 



2. Second molar tooth magnified. 



5. Fifth molar tooth still further magnified. 



B. Fragment of lower Jaw of a small Didelphys from 



Stonesfield, in the Oxford Museum, (magnified one 

 third.) This jaw has been examined by Cuvier, 

 and is figured by M. Prevost, Ann. de Sci. Nat. Avr. 

 1825, p. 389, PI. 18. The removal of a part of the 

 bone displays the double roots of the teeth, in their 

 alveoli, and the form of the teeth shows the animal 

 to have been insectivorous. (Original.) 



4. Fourth molar tooth magnified. 



9. Ninth molar tooth magnified. 



C. 1. Lower Jaw of Dinotherium giganteum, (Tapirus 



Giganteus, Cuv.) The length of this Jaw, including 

 the Tusk, is nearly four feet. V. I. p. 110. (Kaup.) 



2. Lower Jaw and part of upper Jaw of Dinotherium 



medium. (Kaup.) 



3. Jaw of Dinotherium medium, exhibiting the Crown of 



five molar teeth, most nearly resembling those of a 

 Tapir. (Kaup.)* 



* All these unique remains of Dinotherium are preserved in the 

 Museum at Darmstadt; they were found in a Sand pit containing 

 marine shells at Epplesheim near Alzey, about forty miles N. W. of 

 Darmstadt, and are described by Professor Kaup. 



Bones of Dinotherium have lately been found in Tertiary Fresh- 

 water limestone, near Orthes, at the foot of the Pyrenees ; and with 

 them, remains of a new Genus, allied to Rhinoceros ; of several un- 

 known species of Deer ; and of a Dog, or Wolf, the size of a Lion. 



Our figures of Dinotherium are copied from the Atlas of Kaup's 

 Description d'Ossemens fossiles de Mammiferes, Darmstadt, 1832-3.
