The auditor)’ bulla3 are small, little convex, and formed, 
as in nearly till the other Marsupialia, of the aim of the 
sphenoid; the palatine openings are tolerably large, and 
situated for the most part in the palatine bone. The nasal 
process of the intermaxillary bones notches into the nasal 
bones in a very unusual manner. The facial portion of the 
skull is very narrow, and considerably elongated; the skull 
is again much contracted in the temporal region, but broad 
between the orbits, which latter are more than three parts 
enclosed, there being a distinct post-orbital process to the 
frontal, and a corresponding process to the malar bone. The 
zygoma is thrown boldy outwards, leaving a large temporal 
fossa, and it is also arched upwards to furnish greater re¬ 
sistance to the muscles of the lower jaw.
