SIWALIK AND NARBADA CARNIVORA. 
93—270 
In V. civetta b m. l is remarkably short transversely ; in another 
specimen in the British Museum (No. 138, b) m. 2 is extremely large, its transverse 
diameter being T43 ; pm. 4 is unusually short in the same specimen, its length 
being only 0-45. 
These dimensions show that in the fossil the carnassial is about the same size as 
that of the zibeth, its length considerably 
exceeding the united length of the two 
true molars ; whereas in the civet the latter 
diameter is considerably the larger of the. 
two. The true molars of the fossil (as 
may be seen by a comparison of the figure of 
the latter with the accompanying woodcut) are, 
however, different from those of the 
zibeth ; the inner portion of mj. being 
longer antero-posteriorly, and m. 2 alto- 
gether larger : in this respect they agree 
very nearly with those of the civet ; m. 2 
being rather larger than is generally the 
case in that species. The third premolar 
is larger than in either of the existing 
species. As it has been shown above that 
in the dogs a relatively large upper 
carnassial (megalocreodontism), with a reduction in the size of the last true molar, is 
indicative of high specialization, it may be assumed that the same will probably hold 
good for the civets 1 ; and consequently that the zibeth is a more specialized animal 
than the civet. The Siwalik civet must be regarded as intermediate between the 
two, its carnassial having attained the proportions of that of the zibeth, while its 
true molars retain the large size of those of the civet. 
In respect of other characters the condition of the fossil allows of very few 
observations. As the skull appears to agree in size with the zibeth marked a, it 
appears that its palate is relatively wider than in that species, and thereby agrees 
with the civet. Similarly the palate of the fossil, like that of the civet, is produced 
to a greater extent behind the last molar than in the zibeth. Superiorly the fossil 
skull seems to be as much elongated as in the latter. 
Left maxilla . — The left maxilla represented in figure 2 of plate XXXIII., of 
which the measurements have been already given, is another specimen in the Siwalik 
collection of the British Museum. The second true molar has been broken away ; 
but the resemblance of the remaining teeth to those of the type cranium is so close 
that the two may be safely referred to the same species. 
Distinctness as a species. — The foregoing comparisons leave no doubt of the

only to V. civetta. ,
