The animal to which the above skull belonged was not 
quite adult, since the crown of the last molar tooth is but 
little raised above the level of its alveolus, and what is rather

three upper incisors is the largest, and the hindennost 1ms a 
deep groove behind the middle. The muzzle is short, and 
much contracted in front ; the nasal bones are much dilated

part between the nasal bones and the superior maxilhtrv, ns

the zygomatic arch is thrown boldly outwards beneath the 
orbits, and the lateral ridges of the frontal bones are parallel ; 
these bones are nearly flat between the orbits. The occipital 
opening is notched above. 
As compared with the skull of M. penicillatus, that of M.
