Rhinoceros sivalensis, Falconer and Cautley '. 



Syn. Rhinoceros sinensis, Owen 2 . 

 Zalabis sivalensis, Cope 3 . 



Dentition : — I. r^y C. °, Pm. J, M. |. This species is apparently- 

 allied to R. sondaicus (of which it is probably the ancestor), but is 

 usually of larger size. There are two fossettes on the worn crowns 

 of the true molars ; there is no distinct " antecrochet," but a well- 

 developed " buttress." Koken 4 unites one of the type specimens 

 of R. sinensis with this species, but provisionally retains the other 

 as distinct. The writer is inclined to think that both may be 

 included. 



Hob. India and China. 



39626. The middle portion of the cranium, showing the last five 

 (Fig.) cheek-teeth, in a well-worn and somewhat imperfect con- 

 dition ; from the Pliocene of the Siwalik Hills. The right 

 dentition is figured by Falconer and Cautley in the * Fauna 

 Antiqua Sivalensis/ pi. lxxv. fig. 5, and in ' Falconer's 

 Palaeontological Memoirs,' vol. i. pi. xiv. fig. 2. This and 

 the following specimens are the types. 



Presented by Dr. Hugh Falconer. 



39647. The anterior portion of the cranium, showing the whole 

 (Fig.) or portions of each of the seven cheek-teeth ; from the 

 Siwalik Hills. Figured in Boyle's ' Botany &c. of the 

 Himalaya Mountains,' pi. vi. fig. 5, and in the ' Fauna 

 Antiqua Sivalensis,' pi. lxxiii. fig. 3, and pi. lxxiv. fig. 5. 

 The first and second true molars are in good preserva- 

 tion, and agree with the less worn specimen figured by the 

 present writer in the ' Palaeontologia Indica,' ser. 10, vol. i. 

 pi. v. fig. 5, and vol. hi. pi. i. fig. 7 : the right m. 3 has 

 been found and put in position since the specimen was 

 figured. Cautley Collection. Presented, 1842. 



39625. The cranium, wanting the left zygomatic arch and the ex- 

 (Fig.) tremities of the premaxillae and nasals, but exhibiting the 

 last six cheek-teeth, in a half -worn and much-broken con- 

 dition ; from the Siwalik Hills. Figured in the ' Fauna
