the space occupied by the four premolars is 0,0355, and 

 the depth of the jaw at the caraassial 0,0186. 



In the following table the dimensions of the three 

 specimens figured by Filhol under the names of G. minor 

 and 0. brevirostris are compared with those of the present

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 Ganoids ; 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. Geol. vol. iii. 

 pi. xviii. 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.
