29174. Fragment of the right ramus of a mandible, containing m . 3, 

 and the hinder part of m . 2, which may belong to the 

 present genus or species ; from the Headon beds ( Upper 

 Eocene) of Hordwell, Hampshire. The length of m . 3 is 

 0,021. Hastings Collection. Purchased, 1855. 



Genus ANOPLOTHERIUM, Cuvier \ 



Including Eurytherium, P. Gervais 2 . 



Diplobune, Riitimeyer 3 (inparte). 



Great confusion exists in regard to the larger species here in- 

 cluded in this genus, owing to the imperfect definition of one of 

 Cuvier's species, and the circumstance that Gervais' Enriitherium 

 latipes* was founded on bones of the feet. 



The specimens of the dentition and bones of the feet of the larger 

 forms in the Museum may be arranged in two series, as follows : 



Dentition. 



A. Largest form. 



Paris, Yaucluse, and Quercy. 



B. Smaller form. 

 Paris and Vaucluse. 



C. Still smaller form. 



Paris, Vaucluse, and Quercy. 



Foot-bones. 

 A'. Largest tridactyle form. 



Paris, Vaucluse, and Quercy. 

 B' . Smaller tridactyle form. 



Paris and Vaucluse. 

 B" . Equal-sized didactyle form. 



Paris and Vaucluse. 

 C" . Still smaller tridactyle form. 



Paris, Vaucluse, and Quercy. 



The specimens ranged under A comprehend the typical A. magnum, 

 and others from Vaucluse and Quercy which cannot be specifically 

 distinguished, although there is a slight variation in the size of 

 individual specimens from all three localities. The specimens in A! 

 correspond to Euryfherium latipes, and as these are the largest 

 limb-bones, the a priori presumption is that they belong to the 

 same species as the largest teeth, viz. A. commune. This has been 

 practically recognized by Filhol 5 , who provisionally refers the
