The skull of Macropus antilopinus is about equal in size 
to that of M. gigantcus , but is shorter in proportion to its 
width ; and the most striking diiference is in the form of 
the muzzle, which, instead of becoming gradually narrower 
towards the apex, is quite as broad near the end as at the 
base, and is most broad rather in front of the middle; the 
nasal bones are shorter than in M. gigantcus ; the superior 
breadth of the muzzle is caused by the swelling outwards of 
the superior maxillary and nasal process of the intermaxillary 
bones, which thus gives a great expanse to the nasal cavity, 
which encloses very largely developed turbinated bones, and 
hence we may conclude the Antilopine Kungaroo possessed 
unusual acuteness of smell. The frontal bones are deeply 
concave above, between the orbits, and are much contracted 
immediately behind them ; tho temporal ridges meet to form 
a well-marked sagittal crest. The zygomatic arch is thrown 
more boldly outwards than in the M. gig an tens, and is 
remarkable for its great depth ; the lower posterior branch 
of the malar bone descends slightly below T the level of the 
glenoid cavity ; the palate is strongly eoncave in the longi¬ 
tudinal direction; the ordinary posterior palatine openings,
