Dr. Buckland in the Oxford Museum, which is referred to the same 

 species as that first discovered. It shews the exterior face. There 

 are traces of all the teeth, except the canine, whose place is marked 

 by an interval. The teeth are not in general perfect, having been 

 somewhat chipped ; but the number can be well determined. There 

 is some difference between this specimen and that previously noticed, 

 in the form of the jaw, which seems in this to be not so deep, in the 

 position of the articular face in relation to the line of the jaw, and 

 in the degree of prominence of the angular termination b .

A third specimen, represented above, lately received from Stones- 

 field, adds to the information regarding the teeth, though it be 

 quite incomplete as to the figure of the jaw. The teeth are un- 

 usually perfect, and well cleared from the stone. They have not the 

 crowded aspect in Diagram LXXVIII. They are smooth, and are 

 such as to imply vermivorous and insectivorous habits. In all the 

 specimens which shew the angular termination of the jaw, that part 

 has a little bend inward, a character observed in several living mar- 

 supialia ; the number of molar teeth is so great as to surpass that of 

 any known ferine quadruped ; but there is an approach to this cir- 

 cumstance in myrmecobius, a small Australian marsupial. To this, 

 on the whole, the fossil is probably most closely allied ; but certainly 

 the small marsupalia generally seem to be tfye nearest kinsfolk. 



Amphitherium Broderipii is the name given to the second species
