1 . The auditory bulla (except in Nandinia) is ossified, much inflated 



and shows externally that it consists of two chambers, which 

 may or may not be one" behind the other. 



2. The bony meatus auditorius is almost always short, and may have 



its anterior, posterior, or inferior margin most projecting ; and 

 it may be imperfectly ossified below. 



3. The bulla is not more prominent towards its inner than towards 



its hinder border. 



4. There are one or two carotid foramina on each side of the basis

6. The palatine foramina are situated in the anterior half of the
