29689. Fragment of the right maxilla containing two true molars 

 (the first broken) ; from the Lower Miocene of Ronzon.

 op. cit. pi. xvi. Presented by the Earl of Enniskillen. 



29621. Cast of a third lower true molar and an upper molar, 

 provisionally referred to the present species ; from the 

 Lower Miocene of Ronzon. 



Presented by the Earl of Enniskillen. 



27774. Part of the right ramus of the mandible, containing the last 

 four cheek-teeth, in a much-worn condition ; from the 

 Lower Miocene of Ronzon. The length of the space 

 occupied by the three true molars is 0,072.

27787. A last right lower true molar, belonging either to this or 

 the next species ; from the Lower Miocene of Ronzon.

27771. The third left lower milk-molar ; from the Lower Miocene 

 of Ronzon. This specimen is precisely like the corre-

Croizet Collection. Purchased, 1848. 



29784. The symphysis and the greater portion of the left ramus 

 (Fig.) of the mandible ; from the Hempstead beds (Lower 

 Miocene) of the Isle of Wight. This specimen is figured 

 by Owen, loc. cit. pi. viii. figs. 1-4, under the name of H. 

 vectianus ; it shows the alveoli of the incisors and the 

 canine, the third and fourth premolars (the latter not 

 fully protruded), and the three true molars. The length 

 of the space occupied by the three true molars is 0,071 ; 

 that of the corresponding space in a mandible of the con- 

 tinental form described by Filhol in the Ann. Sci. Geol. 

 vol. xii. art. 3, p. 125, being 0,074. The length of the 

 third molar is 0,033, or the same as that of the Ronzon 

 specimens (Filhol, op. cit. p. 128) ; that of m. 3 in H. 

 bovinus (No. 29754) being 0,044. 



Hastings Collection. Purchased, 1855. 



29782. Portion of the right ramus of the mandible, containing 

 pm. 4, mTl, and i^T2 ; from the Hempstead beds of the 

 Isle of Wight. The length of pm. 4 is 0,017, as against 

 0,019 in H. bovinus (No. 29753).
