THE KOALA, or NATIVE BEAR. 
Plate IV. 
Examination of the many small mandibles obtained revealed' 
two which differed materially from all the others in the collection.. 
The one, that of a full grown (adult) animal, was as perfect as could 
be expected, only a portion, a very small portion, of the coronoid 
process being wanting ; the other, that of a younger individual with 
M4 not yet up into line is more imperfect at the coronoid, and has 
also one of the incisors missing. 
They evidently belonged to a comparatively small animal 
which, like the Wombat, has a remarkably broad head ; the 
coronoid process is very much prolonged, and the condyle is a 
considerable distance above the level of the teeth, the angle, too, is 
very prominent and considerably inflected. As regards the teeth,, 
the dental formula is as follows, for the lower jaw : IxtjTT> Purjun 
The incisor is narrow, sharp-edged, and deep antero-posteriorly,. 
the premolar, a little less in length than Mi, has a sharp edge that 
branches posteriorly into two diverging ridges. The four molars 
vary very little in size, the first one being the smallest; they have 
four tubercles or cusps in the shape of sharp curved crests which 
have the concave sides interiorly and the convex sides exteriorly.. 
All these characters are associated with herbivorous animals.
