Anoplotherium secundarium, Cuvier . 

 Syn. ? Anoplotherium laurillardi, Pomel 2 . 



Cuvier originally described this species on the evidence of part of 

 the upper milk-molar dentition 3 , showing that it was " de grandeur 

 un peu inferieure " to A. commune ; but in a subsequent notice 

 denned the latter as being of the size of an ass, and the former as 

 that of a boar. The comparatively large size of the type milk-molars 

 indicates the probability of the present form corresponding to A. 

 secundarium rather than the next. The true molars are of a hypsodont 

 type, and can only be distinguished from those of A. commune by 

 their inferior size. In the case of detached lower teeth the distinc- 

 tion is very difficult. 



Hob. France and (?) England. 



20605. The left maxilla, containing all the teeth except the canine ; 

 from the Tipper Eocene of Debruge, near Apt (Vaucluse), 

 France. The length of the space occupied by the seven 

 cheek-teeth is 0,133, that by the three true molars 0,072, 

 and that by m. 1 and m. 2 0,044. 



Bravard Collection. Purchased, 1852. 



26762. The left maxilla, wanting pm. 2, m. 1, and m. 2; from the 

 Upper Eocene of Debruge. This specimen agrees precisely 

 with the preceding. Pomel Collection. Purchased, 1851. 



30773. Fragment of the right maxilla, containing the second and 

 third true molars, in a well-worn condition ; from the 

 Upper Eocene of Debruge. The teeth agree in size with 

 those of No. 20605. 



Bravard Collection. Purchased, 1855. 



26777. Fragment of the right maxilla, containing two teeth similar 

 to those of the last specimen ; from the Upper Eocene of 

 Debruge. Bravard Collection. Purchased, 1852. 



30583. Fragment of the left maxilla, containing m. 2 and m. 3, in an 

 unworn condition ; from the Upper Eocene of Debruge. 



Bravard Collection. Purchased, 1852. 



30624. Fragment of the right maxilla of an immature individual, 



(Fig.') containing the last three milk-molars, and m. 1 and m. 2
