28 CARNIVORA. 
of Bach, near Lalbenque (Lot), France. This specimen 
is precisely similar to the one figured by Filhol in the 
Ann. Sci. Géol. vol. vii. pl. xxxv. figs. 182, 183, with 
the exception that the depth of the mandible is still 
greater in the present specimen, being 0,029 at the 
interval hetween pm. 3 and pm. 4. Purchased, 1884. 
M. 1677. Fragment of the right ramus of the mandible, containing 
the first and second true molars ; from the Upper Eocene of 
Bach. This specimen agrees precisely with the one figured 
by Filhol in the plate cited above. Purchased, 1884. 
Elyzenodon vulpinus, P. Gervais’. 
Syn. Hyenodon exiguus, P. Gervais (¢este Filhol). 
Pterodon exiguus, P. Gervais. 
This species is readily distinguished from any of the ones ee 
its greatly inferior size. The species has not hitherto been recorded 
from the Lower Miocene of Puy-de-Déome. 
Hab. France. 
36766. Fragment of the cranium, containing all the teeth of the 
right side as far back as the first true molar, and a frag- 
ment of the right ramus of the mandible, containing the 
last premolar and the first and second true molars; from 
the Lower Miocene of Puy-de-Dome, France’. The teeth 
are unworn and in beautiful preservation; and the speci- 
men is valuable as showing the upper and lower jaws in 
association. The specimen is of considerably smaller size 
than the cranium of H. vulpinum figured by Filhol in the 
Ann. Sci. Géol. vol. vii. pl. xxxiv. fig. 170; but it will 
be seen, from the figures of three specimens of the man- 
dible given on the same plate (figs. 167-169), that there 
is a considerable range of variation in size; and since the 
three teeth of the mandible of the present specimen agree 
precisely with the corresponding teeth of the specimen 
represented by Filhol in fig. 168, the present specimen 
may be pretty safely referred to the same species, thus 
extending its range into the Lower Miocene. The upper 
teeth agree exactly with those of the specimen No. M. 1678, 
noticed below. ‘The following dimensions indicate the 
' Journ. Zool. vol. ii. p. 374 (1873). 
* The specimen is entered in the Museum Register as Hyenodon croizeti, 
Kaup; the name being apparently a manuscript one.
