SIWALIK AND NARBADA CARNIVORA.

pm. 4 , as may be seen from the size of its alveolus, relatively large. From this 
precise resemblance there appears to be no doubt that the two specimens belong 
to the same species ; although the second one (a), as may be seen from the following 
dimensions, is rather smaller than the first (b ) : — 
V. durandi. V. zibetba.

The second specimen, although bridging over to some extent the discrepancy in 
size between V. bakeri and V. durandi , serves to confirm the conclusions as to their 
specific distinctness. Thus a comparison of the figures given in the “Fauna 
Antiqua Sivalensis,” 1 or of the originals in the British Museum, will show that while 
in V. bakeri the facial portion of the skull gradually diminishes in width from the 
zygoma to the muzzle ; in V. durandi there is a very sudden contraction in front of 
the anterior zygomatic root, in advance of which the borders of the maxillae are 
nearly parallel. The face of the latter seems also to have been proportionately 
snorter ; while its first premolar is relatively longer than in either the civet or the 
zibeth. 
General characters . — It appears from the foregoing comparisons that Viverra 
durandi is the largest known civet ; and in respect of dental characters more nearly 
allied to the Indian V. zibetha and V. bakeri than to the African V. civetta : presenting 
in some respects characters intermediate between the two former. In its cranial 
characters it is markedly distinct from each of the other three species. 
Distribution . — Both of the two specimens described above were obtained from the 
typical Siwalik Hills. 
It should be mentioned that a fragment of the mandible, containing one perfect 
tooth, of a small carnivore from the Siwaliks of Eastern Bengal has been figured by 
Pentland under the name of Viverra . 2 The specimen is, however, insufficient for 
generic determination : the tooth is figured by De Blainville. 3 
Family IV. : HYJENIDJE. 
This family, according to Professor Mivart, 4 comprehends the two existing 
genera Ilycena (including Cr o cut a), and Proteles ; but the latter is referred by Prof. 
Flower 5 to a distinct family. Professor Gaudry 6 has established a fossil third genus, 
under the name of Uycenictis ; but it will be shown below that there is such a 
complete transition between that so-called genus and Hycena , that it seems necessary 
to merge the one into the other ; or, at all events, not to rank Uyaenictis as of more 
than subgeneric value. A new genus will be described below under the name of
