116 CARNIVORA. 
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. Géol. vol. vi. pl. 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 
Oynodictis, 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. borie, figured 
by Filhol in the Ann. Sci. Géol. vol. vii. pl. 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’. 
Syn. (2) Viverra leptorhyncha, Filhol?®. 
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*. As noticed below, it 
appears impossible to distinguish one variety from Filhol’s so-called. 
Vwerra leptorhyncha, which is really more like Amphictis than 
Vwerra proper, and whose resemblance to Cynodictis is noticed by 
Filhol. 
Hab. France. 
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. 
Purchased, 1884. 
Variety. 
M. 1651. The nearly complete right ramus of the mandible, contain- 
(fvg.) ing the alveolus of the canine and all the cheek-teeth 
1 Tn 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 pm. 4; it may be 
therefore that the figures of the mandible of C. boried are erroneous in this respect.

1883; but separate copies of this memoir are dated 1881. 
4 Filhol remarks that this feature is peculiar to the species ; but it appears 
to obtain in C. boriei and others (vide note 1).
