39721. Cranium; from'the Pliocene of the Siwalik Hills, India. 



(Fig.) This specimen is the type of the genus and species, and is 

 described by Falconer and Cautley in the passage of the 

 'Asiatic Besearches ' already cited. It is also described 

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

 vol. ii. p. 220 et seq. ; and is figured by Falconer and 

 Cautley, of one third the natural size, in figs. 1, la, 16, of 

 plate of the ' Fauna Antiqua Sivalensis : ' it is also 

 figured, of one fourth the natural size, in 'Falconer's 

 Palaeontological Memoirs ' (pi. xxvi. fig. 1). The dentition 

 of one side is figured, of the natural size, in fig. 1 c of the 

 first-mentioned plate ; and, of three fourths the natural 

 size, in fig. 2 of the second plate. The dentition is also 

 figured from the lateral and palatal aspects, of one third 

 the natural size, in plate cxxxi. of Owen's ' Odontography.' 

 In fig. 5 of plate xxx. of the above -quoted volume of the 

 ' Palaeontologia Indica,' the dentition of the left side (the 

 canine having been restored from the opposite side) is 

 figured from the palatal aspect, of the natural size.' 



In this specimen the carnassial (pm 4.) and the two true 

 molars are perfect on the left, and but slightly damaged 

 on the opposite side. Both canines are present, that of 

 the right side being nearly perfect. The alveoli of the 

 premolars and incisors are distinct, although the teeth 

 themselves have dropped out. The only considerable defi- 

 ciencies are in the posterior and lower part of the occiput, 

 both zygomatic arches, and in the lower end of the nasals, 

 where a fissure extends across the face on both sides 

 towards the orbits. Cautley Collection. Presented, 1842. 



39722. Part of the right ramus of the mandible ; from the Pliocene 

 (Fig.) of the Siwalik Hills. This specimen is figured by Fal- 

 coner and Cautley from the outer side (reversed) in plate 0. 

 fig. 2 of the ' Fauna Antiqua Sivalensis ' (3), and in vol. i. 

 plate xxvi. fig. 3 of ' Falconer's PalaBontological Memoirs ' 

 (5) : it is also figured from the dental aspect in fig. 2 a of 

 the former plate (^-), and in fig. 4 of the latter (|) ; and 

 in plate cxxxi. figs. 3 and 4 of Owen's ' Odontography ' (^). 

 It is described by the present writer in the ' Palaeontologia 

 Indica,' ser. 10, vol. ii. pp. 223-4. This specimen is broken 

 off where the canine emerges from its alveolus ; the im- 

 bedded portion of that tooth presenting an antero-posterior 

 diameter of 0,041, and a transverse of 0,025. The
