116 CABNIVORA. 



cheek-teeth ; from the Upper Eocene of Bach, near Lal- 

 benque (Lot), France. This specimen, agrees very closely 

 with the dentition of the cranium, figured by Filhol in the 

 Ann. Sci. Geol. vol. vii. pi. xv. fig. 34; but the last molar 

 is slightly narrower antero-posteriorly. Purchased, 1884. 



M. 1357. The anterior portion of the left ramus of the mandible of a 

 Cynodictis, not improbably belonging to the present species ; 

 from the Upper Eocene of Caylux (Tarn-et-Garonne), 

 France. This specimen shows the canine, the four pre- 

 molars, and the blade of the carnassial ; and in the interval 

 between the carnassial and the canine agrees very closely 

 with the mandible of the smaller race of C. boriei, figured 

 by Filhol in the Ann. Sci. Geol. vol. vii. pi. xvii. figs. 46- 

 48 ; it apparently differs, however, in the greater relative 

 height of the carnassial, which exceeds that of pm. 4 ] . 



Purchased, 1884. 



Cynodictis dubia, Filhol 2 . 

 Syn. (?) Viverra leptorhyncha, Filhol 3 . 



The typical form of this species is of medium size, and is distin- 

 guished by the lowness of the crown of the inferior carnassial, which 

 does not exceed that of the last premolar 4 . As noticed below, it 

 appears impossible to distinguish one variety from Filhol's so-called 

 Viverra leptorhyncha, which is really more like Amphictis than 

 Viverra proper, and whose resemblance to Cynodictis is noticed by 

 Filhol.

M. 1650. Part of the left ramus of the mandible, containing the 

 canine, the last three premolars, and the carnassial ; from 

 the Upper Eocene of Bach, near Lalbenque (Lot), France.

M. 1651. The nearly complete right ramus of the mandible, contain- 

 (Fig.~) ing the alveolus of the canine and all the cheek-teeth 



1 In his description of Cynodictis dubia (Ann. Soc. Sci. Phys. Nat. Toulouse, 

 1882, p. 48), Filhol mentions that that species is distinguished from all others by 

 the circumstance that the lower carnassial is not higher than ^K71 ; it may be 

 therefore that the figures of the mandible of C. boriei are erroneous in this respect.

4 Filhol remarks that this feature is peculiar to the species ; but it appears 

 to obtain in C. boriei and others (vide note 1).
