794. The anterior part of the palatal and alveolar processes of the upper jaw 



of a mature Dinotherium giganteum, with the sockets of the two pre- 

 molar teeth on each side, and three of the right and the first of the left 

 side in situ. These teeth agree in size and shape with the two preceding 

 specimens, but the tuberculate margins of the coronal eminences have 

 been worn away by mastication.

795. A portion of the alveolar process of the upper jaw of a female Dinothe- 



rium giganteum, with three true molars in situ. The first of these 

 corresponds with its analogue in No. 790, but the tuberculate summits 

 of the three transverse eminences have been worn off".

Presented by Dr. Kaup. 



796. The left ramus of the lower jaw of the Dinotherium giganteum, with the 



four anterior permanent molar teeth. The third, counting backwards, 

 has the crown divided into three transverse ridges, and corresponds with 

 the first permanent molar in the upper jaw. The symphysial extremity 

 of the jaw is subcompressed and bent downwards at almost a right angle 

 with the horizontal ramus, and supports two long and strong tusks di- 

 rected downwards and curved slightly backwards.
