MELES

anteriorly, the widest portion opposite front of glenoid fossa, the 

 arch very slightly bowed upward. Anteorbital foramina rather 

 large, sub-circular in outline, their greatest diameter about half 

 that of orbit. Ventral profile of skull slightly concave through- 

 out. Palate moderately wide, the distance between molars 

 contained about 2 J times in distance from gnathion to level of 

 posterior edge of molar. Incisive foramina small, at level of 

 space between canine and i 3 , elongate pyriform in outline, the 

 minute median foramen a little behind middle. Posterior exten- 

 sion of palate about equal to distance between molars, and slightly 

 more than half that from molar to hamular. Mesopterygoid 



x h 



space short and wide, its length only a little more than distance 

 between tips of hamulars. Auditory bull* slightly inflated, 

 irregularly triangular in outline, the meatus lying in angle formed 

 by the large, forward-projecting mastoid process. The surface is 

 irregular, with evident ridge near inner margin along crest of 

 most highly inflated region, this ridge often terminating anteriorly 

 in a bluntly pointed projection. Length of flattened portion 

 extending inward from meatus about equal to transverse diameter 

 of inflated portion of bulla, but the two regions not sharply 

 defined ; least distance between bullae about 1£ times diameter of 

 inflated portion ; paroccipital process short, triangular (not ridge- 

 like), its extreme base applied to posterior border of bulla.
