SPOTTED OPOSSUM. 
The mouth is full of teeth. The lower 
jaw is narrow, in comparison with the upper, 
more especially backwards ; which allows of 
much broader grinders in this jaw than in the 
lower, and which occasion the grinders in the 
upper jaw to project considerably over those 
in the lower. In the middle, the cuspidati op- 
pose one another ; the upper piercers, or holders, 
go behind those of the lower : the second class 
of incisors, in the lower jaw, over-top those 
of the upper ; while the two first in the lower 
go within, or behind, those of the upper. In 
the upper jaw, before the holders, there are four 
teeth on each side ; three of which are pointed, 
the point standing on the inner surface: and 
the two in front are longer, stand more ob- 
liquely forwards, and appear to be appropriated 
for a particular use. The holders are a little 
way behind the last fore teeth, to allow those 
of the lower jaw to come between ; they 
are pretty long: the cuspidati, on each side, 
become longer and larger towards the grinders ; 
they are points, or cones, placed on a broad 
base.
