Li CARNIVORA. 
evidence of the mandible, it is very difficult to make any 
certain determinations of the corresponding crania. The 
whole of the cheek-teeth are shown on the left side, and — 
the first incisor of the same side is also in situ, the other 
teeth being represented merely by their alveoli. The first 
premolar is small and one-rooted, and is separated by a 
considerable interval from pm. 2, which is likewise small, 
and separated by an interval from pm. 3; the latter has 
a minute cusp on its posterior cutting-edge. The carnas- 
sial is a relatively short tooth, with a well-developed inner 
tubercle. The true molars are transversely elongated. 
The cranium seems not dissimilar in shape and size to that 
of Cynodictis grye (Filbol, op. cit. vol. vil. pl. xix.) ; but 
the two are very readily distinguished by the different form 
of the teeth (compare woodcut, fig. 14). Purchased, 1884. 
M. 1667. Anterior portion of the right ramus of the mandible, con- 
taining the third and fourth premolars and the alveolus of 
the canine; from the Upper Eocene of Bach. 
Purchased, 1884. 
Cynodictis compressidens, Filhol’. 
Syn. Cynodictis angustidens, Pomel and Bravard, MS. (?). 
This is a medium-sized species, with relatively well-developed 
teeth, the cusps of the lower carnassial being very tall. In one race 
m.2is absent. The species has not hitherto been recorded from 
Vaucluse. 
Hab. France. 
M. 1352. The greater portion of the left ramus of the mandible ; 
from the Upper Eocene of Caylux (Tarn-et-Garonne), 
France. This specimen appears to agree precisely with 
the type mandible figured by Filhol in the Ann. Sci. Géol. 
vol. vii. pl. xxv. figs. 117-119, and shows part of the 
alveolus of the canine, the alveolus of pm. 1, the last three 
premolars, the first two true molars, and the alveolus of 
m. 3, Which is of extremely minute size. Purchased, 1884. 
M. 1353. The complete left ramus of the mandible, wanting the 
incisors, canines, pm. 1, pm. 3, pm. 4, and m. 3; from the 
Upper Eocene of Caylux. Purchased, 1884. 

28128. Fragment of the right ramus of the mandible, containing 
pm.3 and the anterior half of m.1; from the Upper 
1 Ann. Sci. Géol. vol. iii. art. 7, p. 26 (1872).
