341—164 INDIAN TERTIARY AND POST-TERTIARY YERTEBRATA. 
mediate dental characters as to leave little doubt of the generic unity of the typical 
machserodonts. 
Distribution. — The present species ranged from the typical Siwalik Hills to the 
Punjab. 
Species 2 : Mach^erodus palatndicus, Bose. 
Syn. M. sivatensis (Falc. and Caut.), in parte. 
Bistory. — The history of this species has been already given under the head of 
M. sivatensis. 
Type mandible. — In figure 3 of plate XLIV. there is represented, from the 
external aspect, the distal extremity of the left ramus of the mandible of the present 
species ; being the specimen in the Siwalik collection of the British Museum on the 
evidence of which the species was founded. 1 The fragment shows the alveolus of 
the canine (e), behind which there is a comparatively short diastema, followed by the 
alveolus of pm. 3 ; which was relatively small, and apparently inserted by a conjoint 
fang : behind this again there is the crown of pm. 4, considerably damaged. The 
jaw is abruptly broken off behind the last-named tooth. The descending symphysial 
expansion is unusually large, commencing immediately in advance of pm. 4 ; and its 
inferior border maintaining a gradual descent as far as the anterior extremity of the 
specimen, where a bold ridge, descending considerably below the inferior symphysial 
border, marks the division between the lateral and anterior faces of the ramus. 
There is a strongly marked fossa on the outer surface of the symphysial expansion 
for the reception of the upper canine, which must have been of large size. 
Second specimen. — In figure 4 of the plate accompanying Mr. Bose’s memoir 
there is represented a fragment of the right ramus of the mandible of a feline, 
which from the relatively large size of the cheek-teeth must be referred to the 
present genus. The specimen is in the Siwalik collection of the British Museum 
(No. 48,437), and contains pm. 4 and m. 1. The length of the former tooth is very 
nearly the same as in the mandible described above ; but the horizontal ramus has a 
smaller vertical depth ; and at the point where the jaw is fractured there is no sign 
of the commencement of the descending symphysial expansion, which is well marked 
at the same point in the type specimen. In all other respects the two jaws agree so 
closely that they must be referred to the same species ; the above-mentioned 
differences being probably accounted for in the same manner as in the case of M. 
sivatensis ; viz., by referring the type specimen to a male, and the present specimen 
to a female individual : the latter sex being characterized by the smaller extent of 
the symphysial expansion of the mandible, and the shorter upper canines. 
Third specimen . — In figure 8 of plate XLIII. of the present volume there is 
represented a fragment of the right ramus of a mandible, precisely similar to the 
last specimen, containing the bases of pm. 3, and pm. 4 ; the latter wanting the summit 
l The specimen is also represented in figs. 1, 2, 3 of the plate accompanying Mr. Bose’s memoir (op. cit.). These figures 
show the internal and anterior aspects.
