FAUNA ANTIQUA SIVALENSIS. 



X. ON CHALICOTHEEIUM SIVALENSE. 



BY H. FALCONER, M.D. 



On November 15, 1843, a paper by Major Cautley and my- 

 self was read to the Geological Society, entitled ' On some 

 Fossil Remains of Anoplotberium and Giraffe from the Sewalik 

 Hills,' &c., an abstract of which appeared in No. 98 of the 

 Society's 'Proceedings.' In the concluding remarks upon 

 the species referred to Anoplotlieriwm, we stated that our 

 fossils came nearest to the Chalicotherium of Kaup, and that 

 the generic determination then assigned to them by us was 

 to be considered more as provisional than positive, pending 

 the discovery of other more conclusive materials. This 

 opinion is expressed in the ' Abstract ' in the following 

 terms : — 



' On the whole the Sewalik species appears to be most 

 closely allied to the Chalicotherium Goldfussi. The existence 

 of a vacant diasteme in front of the anterior tooth would 

 constitute a difference from the Anoplotherian type of some 

 importance. The characters generally show a retiu-n from 

 the riuniuant tendencies of the Cuvierian species back to 

 a more pachydermatous type and a closer afiinity with 

 Rhinoceros, between which and Anoplotherium commune it 

 may ultimately prove to be an intermediate form. Until the 

 evidence for separation is conclusive, the authors suggest 

 leaving it with the genus Anoiilotherium.'' (' Proceedings,' 

 No. 98, p. 239 ; and antea, p. 195.) 



Our reasons for hesitating to adopt Kaup's generic name 

 of Chalicotherium arose from our entertaining doubts regard- 

 ing the validity of the grounds urged by that eminent 

 palaeontologist,^ for establishing the genus as distinct from 

 Anoplotherium. The characters adduced by Kaup were, 

 the ascertained form of the back molars of the upper 

 jaw, but more especially the supposed form of the incisors 

 and canines. We suggested that the complicated crovm
