Molars. — The anterior talons are very short, the posterior 

 moderately long and connected with their lobes by strong linking 

 ridges. The fore and mid links run from the outer end of the 

 crest of the lobes to the middle of the fore lobe and anterior 

 talon respectively. The lobes are set obliquely to the line of the 

 teeth, and this oblic(uity combined with the continuity of the end 

 of one lobe with the middle of the next confers upon the series a 

 facies peculiar to the genus. 



Upper incixors. — (PI. xiv, fig. 10.) The arch formed by the series 

 is broad and flat; the teeth increase in breadth from the central 

 pair outwards, but in the figure the relative width of the outer 

 pair has not been duly represented by the artist. 



Succession of teeth. 



Of this nothing is known, except that the premolar is retained 

 to old age.
