CARNIVORA 



Auditory bullae inflated along inner border, elsewhere rather flat, 

 their general form elongate flask-shaped (transverse diameter 

 greatest), much like that in Meles }nch'i>, the nieatal tube rather 

 long but not sharply differentiated from main portion of bulla. 

 Postorbital region less abruptly contracted than in Meles meles 

 and Martes martes, its width slightly more than half that of 

 bi*ain-case. Interorbital region about as wide as rostrum, 

 smoothly convex both longitudinally and laterally. Postorbital 

 processes short but relatively better developed than in Martes. 

 Rostrum short and heavy, the width across canines equal to 

 distance from ajnathion to infraorbital foramen. Orifice of

anteorbital foramen relatively small, its actual size scarcely 

 greater than that in Martes martes, its situation over posterior 

 root of jm^ and noticeably in front of anterior margin of rather 

 small orbit, a peculiarity not shared by any of the other European 

 members of the family. Zygomata essentially as in Martes 

 martes, but less bowed upward, and very noticeably comj^ressed 

 and deepened, especially over glenoid region. Palate rather 

 liroad, its width between molars equal to nearly 2i times greatest 

 diameter of molar ; incisive foramina elliptical, slightly oblique, 

 between canines, the minute median foramen between anterior 

 borders ; posterior extension and mesopterygoid space essentially
