39646. The symphysis of the mandible, showing the left canine, 

 (Fie/.) the alveolus of the right, and the broken bases of the 

 incisors ; from the Siwalik Hills. This specimen is figured 

 by Falconer and Cautley, op. cit. pi. Ixxiv. fig. 4, under 

 the name of R. palceindicus, but is referred to this species 

 by the present writer in the ' Palseontologia Indica,' scr. 10, 

 vol. ii. p. 38 l . A very similar specimen, which does not 

 show incisive alveoli, is figured in pi. vi. fig. 3 of that 

 volume. Cautley Collection. Presented, 1842. 



Rhinoceros palseindicus, Falconer and Cautley 2 . 



Dentition : I. J, C. , Pm. \, M. f. 



This species is readily distinguished from the last by the absence 

 of a "buttress" to the upper true molars, and their horizontal wear, 

 as well as by the usual presence of three fossettes on the worn 

 crowns of the latter. The upper true molars are somewhat simpler 

 than those of R. unicornis, of which the present species may be the 

 ancestor.

16444. The cranium, wanting the extremities of the premaxillse 

 (Fig.) and nasals, and showing the last six cheek-teeth, in a much- 

 worn and somewhat battered condition ; from the Pliocene 

 of the Siwalik Hills, India. Figured by Falconer and 

 Cautley in the ' Fauna Antiqua Sivalensis,' pi. Ixxiii. fig. 1. 

 This and the following specimens are the types ; the three 

 fossettes are shown in several of the teeth.

M. 2727. The cranium, incomplete anteriorly, but showing the 

 (Fig.) last four cheek-teeth ; from the Siwalik Hills. Figured 



in the ' Fauna Antiqua Sivalensis,' pi. Ixxiv. fig. 2. Three 



fossettes occur in m. 1.

M. 2728. Middle portion of a cranium apparently belonging to a 

 smaller individual of this species ; from the Siwalik Hills. 

 On the right side the three true molars are shown, and 

 in the absence of a " buttress " agree with those of the 

 present species. Cautley Collection. Presented, 1842. 



1 The cast, from which the description was taken, did not show the existence 

 of the incisors.
