the space occupied by the four premolars is 0,0355, and 
the depth of the jaw at the carnassial 0,0186. 
In the following table the dimensions of the three 
specimens figured by Filhol under the names of -C. minor 
and C. brevirostris are compared with those of the present 
and the two preceding specimens, viz. :—

In Filhol’s specimen No. 2 the second true molar is 
relatively short, and, if this be borne in mind, it will be 
seen that there is such a gradual increase in point of size 
from the smallest to the largest specimen that no distinc- 
tion can be drawn in this respect; and since there is no 
structural difference in any of the specimens, it seems 
necessary to refer them all to one species, and to abolish 
Filhol’s Cephalogale minor. Purchased, 1884. 
Bones provisionally referred to large Canoids ; from the Upper- 
Eocene Phosphorites of France. 
M. 1710-11. An associated right humerus and left tibia; from 
Bach, near Lalbenque (Lot), France. These bones are 
slightly larger than two specimens of the homologous 
bones figured by Filhol in the Ann. Sci. Géol. vol. i. 
pl. xvui. figs. 42, 43, but present precisely similar charac- 
ters. It has been suggested that the figured specimens 
may belong to Brachycyon gaudryi, Filhol. The humerus 
is remarkable for the great width of the distal extremity, 
and especially of the part surrounding the entepicondylar 
foramen, which is of very large size. There is a supra- 
condylar perforation, which is not found in Amphicyon. 
Purchased, 1884. 
M. 1712. The right calcaneum of a large Carnivore; from Jamb- 
lousse, near Limogne (Lot), France. Purchased, 1884.
