specific distinctness of the Siwalik civet both from V. civetta and V. zibetlia ; and as 
the other living species (as well as Fossa ) are all considerably smaller than the latter, 
the fossil cannot be the same as any living species. Of the named fossil species 
given in the foregoing list the only one approaching in size to the Siwalik form is 
V. angustidens , of which . only the mandible is known. That part indicates, however, 
a shorter- jawed animal than the Siwalik civet; while the extremely short talon of 
mTl is very different from the corresponding part in the civet and zibetli : the relative 
shortness of the whole of xuTl in V. angustidens is moreover quite unlike the form 
of that tooth in the zibeth. Since it is probable that m. 1 of the Siwalik fossil 
was very similar to that of the zibeth, it is pretty certain that the former is specifically 
distinct from V. angustidens : and it may accordingly rank as a distinct species, under 
the name applied by Mr. Bose. 
The megalocreodont character of Viverra bakeri indicates that it cannot in all 
probability have been the ancestor of the African V. civetta : it is, however, extremely 
probable that it may have given rise to the Indian V. zibetlia ; the reduced size of the 
true molars of the latter being a later specialization. 
Distribution. — The two specimens described above are the only ones that can be 
referred to V. bakeri ; and were both obtained from the typical Siwalik Hills. 
Species 2. Viverra durandi, n. sp., nobis. 
Syn. (?) Canis, sp., Falc. and Caut. 
History. — The specimen on which this species is founded is mentioned here for 
the first time ; while a second specimen has been hitherto referred to another genus. 
Cranium. — In figure 3 of plate XXXIII. there is represented from the palatal 
aspect the cranium of a viverroid animal from the Siwaliks, lately presented by 
Prof. George Busk to the British Museum, which was originally in the possession of Dr. 
Falconer, and was probably obtained from the typical Siwalik Hills. The specimen 
has lost its anterior portion, which has been separated by an oblique fracture a short 
distance in advance of pm. 4 : the hinder part of the palate shows the last three 
cheek-teeth of either side in fair preservation. On the left side the zygomatic arch 
is preserved; but the specimen is so fragile that it has not been deemed advisable to 
clear it from matrix. The auditory bulla of the same side is present ; as well as the 
right occipital condyle ( con ). On the superior aspect (not figured') the frontal and 
parietal regions are well exposed, and are in fair preservation. 
The form of the whole skull and teeth leaves no doubt that the specimen should 
be referred to the present group of animals. Its extremely large size, the anteriorly 
pointed auditory bulla, the relatively large size of m, 2 , and the large inner portion 
of ml, are all characters of Viverra , as distinct from Genetta and other genera ; and 
the specimen may, therefore, be referred to the former. In the following table its 
dimensions are compared with those of the skulls of V. bakeri , V. civetta , and V. 
zibetlia , mentioned in the preceding table : —
