molar from the Siwaliks, which was referred to the present genus, with the provisional 
name sivalensis. 
Upper molars. — The above-mentioned tooth is represented, of twice the natural size, 
in the two figures on the right side of the accompanying woodcut ; the U2)per figure 
being taken from the masticating, and the lower from the outer aspect. The tooth 
belongs to the left side, and appears to be the last of the true molar series : the 
crown is about one-third worn down. It was obtained by 
Mr. Theobald from the Siwaliks of Asnot, Punjab. 
This tooth is of the same size and shape^ as the cor- 
responding molar of the existing Tragiilus meminna ; the only 
perceptible difference between the two being that the first 
costa of the anterior lobe of the fossil is rather more pro- 
minent than in the living species.^ In this respect the fossil 
makes some approach to Moschus, but is distinguished by the 
later period at which the worn dentine surfaces of the inner 
crescents unite, and by the less elongated form of the crown. 
The resemblance of the molar teeth of the different 
existing species of Tragulus is so close that it seems doubtful 
if any distinction beyond differences in size can be drawn 
between them. The resemblance existing between the fossil 
tooth and the molars of T. meminna renders it almost certain that the former belongs 
to the same genus ; but additional remains are required before specific characters can 
be determined. In the meanwhile in order to record the probable occurrence of the 
genus in the fossil state the Siwalik form may retain the provisional name of T. 
sivalensis. 
The occurrence of this essentially Oriental genus in the Siwaliks is only what 
might have been expected ; and it is to be hoped that additional remains may be 
forthcoming, which will indicate the relationship of the fossil to the living species. 
Family; CEBVIUM. 
Genus : MOSCHUS, Linn. 
Distribution . — The genus is now represented by M. moschiferus^ and is essentially 
Palsearctic, although ranging within the northern limits of the Oriental region. An 
allied genus Amphimoschus has been named from the miocene of Europe ; but it does 
not appear that the genus Mosclius has been certainly obtained in the fossil state, 
although certain remains have been so named. The earlier upper premolars are 
selenodont.
