provisionally referred to it (' Palseontologia Indica/ ser. 10, vol. iii. 

 pp. 11, 14) presents well-marked distinctions from H. gracile, but 

 it is not certain that this specimen may not belong to the same 

 form as certain jaws from the Punjab figured by the present writer 

 in the ' Palseontoiogia Indica,' ser. 10, vol. ii. pi. xi., under the 

 present name. A specimen (No. M. 2646), noticed below, indicates 

 that these specimens may be specifically distinct, this being con- 

 firmed by the Punjab teeth being found in association with the 

 distal articular surfaces of small-sized lateral metapodials, and with 

 first phalangeals of a stouter type than those referred to the present 

 form. If this inference should be correct, the Punjab form may be 

 named H. punjabiense.

M. 2647. Part of the right maxilla, showing all the cheek-teeth 

 {Fig.) except pm. 1 ; from the Pliocene of the Siwalik Hills, 

 India. This specimen is the type, and is figured (reversed) 

 by Falconer and Cautley in the ' Fauna Antiqua Siva- 

 lensis,' pi. lxxxii. figs. 13, 13 a; m. 3 is only just touched 

 by wear. Presented by Dr. Hugh Falconer. 



16170. Middle portion of the cranium, showing pm. 4 and the three 

 {Fig.) true molars ; from the Siwalik Hills. Figured by Falconer 

 and Cautley, op. cit. pi. lxxxii. fig. 16. 



Cautley Collection. Presented, 1842. 



M. 2646. Part of the maxilla of a young individual, showing the 

 three milk-molars and m^J. ; f ro m the Siwalik Hills . 

 The first true molar is well worn ; the milk-molars agree 

 nearly in length with those of the younger specimen from 

 the Punjab figured under the name of H. antilopinum in 

 the ' Palseontoiogia Indica,' ser. 10, vol. ii. pi. xi. fig. 2, 

 but are relatively narrower, as is shown by the following 

 measurements : — 



No. M. 2646. Punjab jaw. 



Length of mm. 3 0,024 0,025 



Width „ „ 0,020 0,024 



Length of mm. 4 0,025 0,026 



Width „ „ 0,020 0,0242 



This difference, as already observed, not improbably in- 

 dicates specific distinction.
