29582. Fr***""" -^ to Euryiherium latipes on the grounds that they 

 .-Baited with the foot-bones of that form (A 1 ), although at the 

 same time remarking that they are practically indistinguishable 

 from the Paris specimens of the dentition of A. commune. 



The specimens ranged under B indicate a smaller form, which the 

 writer is disposed to identify with Cuvier's Anoplotherium secun- 

 darium. Both the didactyle and tridactyle foot-bones from the 

 same two localities, arranged under B' and '', would agree in 

 relative size very fairly with this form ; and this marked difference 

 in the foot may indicate that B really comprehends two species in- 

 distinguishable by dental characters alone. The foot-bones ranged 

 under B" are those referred by Cuvier to AnoplotJierium commune. 

 The reasons against this view are the same as those for identifying 

 E. latipes with that species. 



The smaller teeth classed as C agree well in cize with the limb- 

 bones ranged under C', and correspond with specimens referred by 

 Filhol to Anoplotherium secundarium. Assuming, however, the 

 correctness of the reference of the form B to that species, the form 

 G will be distinct, and is therefore referred to another species under 

 the name of A. cayluxense. 



The foregoing correlation requires careful verification with the 

 specimens in the Paris Museum, and the writer has therefore merely 

 referred specimens of the dentition to the various species mentioned 

 below, arranging the specimens of the foot-bones in proximity to 

 those species with which they appear to agree best, and not ad- 

 mitting any species founded merely on that portion of the skeleton. 



The slight differences in the lower dentition of the so-called 

 Diplobune do not appear to the writer to be worthy of generic 

 distinction.
