112 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 gryei (Filhol, op. cit. vol. vii. pi. xix.) ; but 

 the two are very readily distinguished by the different form 

 of the teeth (compare woodcut, fig. 14). Purchased, 1884. 



It. 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 

 m72 is absent. The species has not hitherto been recorded from 

 Vaucluse. 



Hob. 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. Geol. 

 vol. vii. pi. xxv. figs. 117-119, and shows part of the 

 alveolus of the canine, the alveolus of piuTl, the last three 

 premolars, the first two true molars, and the alveolus of 

 m73, 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 mTl ; from the Upper 

 1 Ann. Sci. Geol. vol. iii. art. 7, p. 26 (1872).
