right side of the upper jaw of the present species; it ex¬ 
hibits the characteristic premolar, and two of the true molar 
teeth ; the three teeth together measure Of lines, of which 
the premolar is lines in length ; it has about six 
vertical grooves on the outer side. In the breccia attached 
to this fragment is an incisor tooth of a Rodent, allied to 
the Rats. 
Figs. 2, 3, 1, and 5, of Flate 3, will convey an idea of the 
general form of the skull, and of the relative position and 
form of the teeth, in the Kangaroo family.

t, the incisor teeth; p-w, the premolar; m, the four molar 
teeth.

Fig. 5. An unworn molar tooth of the upper jaw, viewed from the inner 
side; a, the anterior principal transverse cusp; b % the posterior 
ditto ; c, a small longitudinal ridge in the middle of the tooth; 
d, a portion of the band, which is prominent on the fore part 
of the tooth, wanting on the outer side, and slightly developed 
on the inner side, at f, and on the back of the molar, at e.— 
This tooth is magnified.
