Jabi, Punjab. It sliows the hinder portion of the alveolus of the canine, the 
complete pm. 3, and the broken pm A. In the following table the dimensions of this 
specimen are compared with those of a mandible of F. isabellina , in the writer’s

These dimensions are so -close as to be well within the limits of individual 
variation ; and indicate without much doubt that the fossil belonged to one of the 
lynxes. Seeing, however, the doubts which still prevail as to the number of the 
existing species, it would be unwise to attempt to determine the species of the 
Siwalik form. The talons of pm. 6 in the latter are intermediate between those of 
the isabelline lynx noticed above, and those of the northern lynx figured by De 
Blainville. 1 
Species 5 : Felis subhimalayana, Bronn. 
History . — In 1830 Messrs. Baker and Durand described 2 the cranium and other 
remains of a small Felis from the Siwaliks, without assigning to them any specific 
name. In Bronn’s “Index Palseontologicus ” these specimens are named F. 
subhimalayana * ; and this name is accordingly adopted here. 
Cranium . — The cranium is represented in figure 1 of plate XXVII. of Messrs. 
Baker and Durand’s memoir, and is now preserved in the Science and Art Museum, 
Dublin. 4 It is described as being somewhat, though not extensively mutilated ; 
“ the most serious injury which it has sustained (as being the only one affecting the 
measurements) is a slight crush or compression, which has apparently flattened and 
perhaps widened the cranium. The proportions between the fossil and the skull of 
a common-sized wild or jungle cat are as follows : — the length from posterior border 
of occipital condyle to anterior of canine tooth being taken as the unit or modulus, 
and those dimensions only being collated in which the greatest differences exist. 
The two skulls may be understood to correspond in other respects.

“ The differences o’f proportion exhibited by the foregoing comparison are, as 
will be seen, very trivial. Setting aside the excess in breadth of the fossil cranium,
