It will be seen from these dimensions that the present specimen is very much 
larger than the skulls of either of the other three species : — so much so in fact that 
on this ground alone it is probable that it should be referred to a distinct species. 1 
In regard to other points, it will be observed that the length of pm. 4 is greater than 
the united length of m. I and im 2 ; indicating that the specimen is a megalocreodont 
form, and, therefore, specifically distinct from V. civetta. In regard to V. bakeri , it 
will be seen from the measurements that in the specimen m. 1 becomes relatively 
narrower internally ; more nearly resembling in this respect the corresponding tooth 
of the zibeth. The proportionate size of m. 2 is, however, about the same as that of 
V. bakeri ; and, therefore, larger than that of the zibeth ; its antero-posterior 
diameter is relatively smaller than that of the corresponding tooth of the civet. In 
both V. bakeri and V. zibetha the inner border of m. 1 is placed in advance of that of 
m.2 , whereas in the present specimen these borders occupy the same antero-posterior 
line. The outer border of m. 2 in the latter forms a continuation of that m 1 ; this 
line being placed very obliquely to the antero-posterior axis of the skull : in V. 
bakeri , on the contrary, the outer border of m, 2 is placed externally to that of m. 1 , 
and both are set less obliquely to the cranial axis. The zibeth is in these respects 
more like the present specimen. The angle formed by the junction of the outer 
borders of pm. 4 and m. 1 } m. 2 in the present specimen is, however, much less open 
than in either of the other species. The hinder border of the palate is very different 
from that of the zibeth, being produced some distance behind m. 2 } in the manner of 
V . bakeri : it appears, however, that the form of the opening of the posterior nares 
is somewhat different in the two, as may be seen from a comparison of the figures. 
In V. bakeri the frontals are less contracted behind the post-orbitals, while the hinder 
part of the skull is relatively shorter. Further comparisons between the two are 
impossible • but it would appear from the differences mentioned above, together with 
the great discrepancy in respect of size, that the skull under consideration is 
specifically distinct from that form. In addition to the points of distinction already 
i It will, however, be shown below that there is a specimen intermediate in size.
