269—92 INDIAN TERTIARY AND POST-TERTIARY VERTEBRATA. 
Cranium . — The above-mentioned cranium is represented of the natural size in 
figures 1, la, of plate XXXIII of the present volume. It is considerably damaged, 
apparently from lesions before it became buried in the rock ; but the hinder part of 
the palate is fairly perfect, and exhibits on either side the four last cheek-teeth in 
excellent preservation. The elongated form of the cranium indicates without 
doubt the viverrine affinities of the specimen ; while its large size, absence of any 
inner cusp to pm. 3 , large inner portion of m.Jfj ; and relatively large size of m 2 , 
are all distinctive characters of Viverra as given above. Mr. Bose’s generic 
determination may accordingly be accepted. 
In describing the specimen, Mr. Bose observes : “ The skull indicates an 
animal of nearly the same size as the Civet (V. civettaj. The third premolar, which 
is proportionately larger than the corresponding tooth in the latter, consists of a 
stout triangular crown, and presents no division into accessory lobes, anteriorly, 
or posteriorly. The cingulum is well pronounced, and sends up a ridge anteriorly, 
which, meeting with its fellow from behind, divides the crown into two parts, of 
which the external is much more convex than the internal. The sectorial [~pm. 4 ] is 
like the corresponding tooth in the Civet, but proportionately larger. The anterior 
of the two lobes into which its blade is divided is thick and conical, with a small 
accessory lobule in front, and is mapped off by a notch from the posterior lobe. 
The internal tubercle is stout and strong, and separated by a deep valley from the 
outer lobes, as in the Civet. The first tubercular f m. 1] is triangular and tricuspid, 
and is a little larger than the corresponding tooth in that species. The two sub- 
equal outer cusps are ground down into flattened • crescent-shaped disks ; and the 
inner cusp is separated from them by a deep pit. The second tubercular [ny_2] is 
proportionately longer laterally [transversely], and narrower antero-posteriorly than 
the corresponding tooth in the Civet.” 
In the following table the dimensions of the fossil cranium (a), 1 and of the 
maxilla (b) represented in figure 2 of the same plate, are compared with those of 
V. civetta and V. zibetha. The specimens of V. civetta , are (a) one in the British 
Museum (No. 138, d); (b) another in the same collection (No. 76, 9, 26, 13); and 
one (c) figured by De Blainville 2 ; those of V. zibetha are (a) one in the writer’s 
collection (fig. 11), and (b) another in the College of Surgeons (No. 455).
