CIIALICOTHERIUM SIVALENSE. 209 



and tlie compo-und fang- of the tooth regarded by him as an 

 incisor proved it rather to be one of the anterior premolars, 

 an inference which has proved to have been correct ; and 

 that the supposed upper canine resembled more the incisor of 

 a species of Ehinoceros, to which it would appear Dr. Kaup 

 now refers it. The only other adduced character was the 

 form of the back molars, which, admitting the amount of 

 difference indicated, did not appear to us to be of sufficient 

 importance to constitute, alone, the basis of a generic dis- 

 tmction, as these molars upon the whole exhibited little 

 more than ' an enlarged and less rectangular representation 

 of those of Anoplothermm,' with which they entirely agreed 

 in the insulation of the conical cusp, so characteristic of that 

 genus. 



Since the date of the memoir in question additional 

 materials have turned up to us, which fully establish the 

 validity of Kaup's genus; while they prove at the same 

 time the Sewalik species of Ghalicotheritim, through a very 

 unexpected combination of characters in the construction of 

 the jaws, to have been widely different from Anoplotlierium. 

 So unexpected, indeed, are those characters that Ghalicotherium 

 must be regarded as one of the most remarkable and aberrant 

 pachyderms that has yet been met with, either in the fossil 

 or recent state. 



The object of the present communication is to make 

 known the nature of the new evidence respecting the Indian 

 fossil species, and to extend its comparison with the European 

 species, upon the additional specimens discovered at Eppel- 

 sheim, which have been figured and described by Kaup in 

 the ' Akten der Urwelt.' It would appear, by a manuscript 

 communication from Mons. Pomel, that remains of the same 

 genus, and probably of the Eppelsheim species, have been 

 discovered in the rich ossiferous beds near Sansans, in 

 the south of France, associated with Dinotherium, Mastodon, 

 and ether forms characteristic of the miocene deposits of 

 Eppelsheim. 



The specimens now at our disposal put us in possession of 

 the whole of the dental characters of Ghalicotherium Sivalense. 

 The most important is a fragment comprising the anterior 

 half of an adult head, with the upper and lower jaws in 

 natural apposition, and exhibiting the greatest portion of the 

 dental series of both jaws (Plate XVII. figs. 3 and 4) . The two 

 back molars, deficient in this specimen, are fortunately shown 

 in the most perfect state of preservation by the fragments re- 

 presented in our previous memoir (Plate XVII. figs. 1 and 2). 

 This beautiful specimen, originally in the Dadoopoor collec- 

 tion of Major Baker and Captain Durand, of the Bengal
