presence of premolar 1, which is so constant in all known species of 

 Hycena, living or fossil ; and the canine is separated by a short 

 diastema from premolar 2 (first of the molar series in the fossil). 

 This tooth is two-fanged, and resembles the corresponding tooth of 

 Eycena in its dimensions, as may be judged by its base, the crown 

 being broken off. The second false molar too (pm. 3) is in form and 

 size hjsenoid. The sectorial is proportionately larger than in the 

 living Indian Hyaena, and is provided with a very strong and stout 

 internal tubercle. The alveolus of the tubercular molar, preserved 

 on the right side, is situated as in the Felidae, and shows tbat tooth 

 to have been transverse and exceedingly small, thus differing from 

 H. striata and H. sivalensis. The sagittal crest is very prominent 

 and quite Hya^na-like, gently sloping on the sides ; but the occi- 

 pital crest is proportionately higher than in any other species of 

 Hycena. The specific name given to the fossil is based on the 

 approach it makes to feline organization, especially in the entire 

 absence of premolar 1 from the upper jaw. 



In the following measurements the skull of the living Indian 

 Hyaena* selected for comparison is a little smaller than the fossil ; —

The specimens consist of a mutilated cranium with the third 

 premolar (pm. 3), the sectorial, and the two tuberculate molars of 

 both sides in situ, and a portion of the upper jaw containing the 

 sectorial and the first molar. On the authority of the 'Palaeon- 



* B. M. no, 136, c. It is from the Northern Circars.
