TYMPANIC BULLA IN HYENAS. 307 



in the Cats, and beneath its anterior end, and concealed by it, 

 there is a foramen j^iercing the sphenoid and remote from 

 the foramen lacerum medium. This sphenoidal foramen seems 

 to correspond exactly with the exposed foramen by which the 

 internal carotid artery in the Mongooses enters the skull, 

 after traversing the bulla. In the Hysenas, nevertheless, this 

 artery is said by Mivart to enter the skull by the foramen 

 lacerum medium, the existence of a carotid foramen in the 

 sphenoid being denied by that author. The foramen, never- 

 theless, persists, as it does in Proteles, whether the carotid enters 

 it or not."

 animals of that country in their natural state.
