SIWALIK AND NARBADA CARNIVORA.

extremity of the blade is, however, somewhat in advance, but the hinder end of 
pmTb is enclosed in the angle between the blade and tubercle, as in II. crocuta, and is 
not entirely in advance as in II. striata. The third premolar has the large inner 
cingulum, the high, crown, and the small hind talon, characteristic of the present 
form ; but the vertical ridges are placed farther apart than in the last specimen, 
being more like those of the type skull. The true molar in this specimen in 
respect of size is intermediate between the same tooth in the two skulls described 
above, and is placed close to the carnassial. The specimen may be provisionally 
referred to the same species as the skulls. 1 The dimensions of the two specimens 
described above are as follows, viz . : —

In figure 4 of plate XXXV. there is represented the left maxilla of a Siwalik 
hyaena, collected by Mr. Theobald in the Punjab : it shows pm 3, and pm 4 (the 
latter somewhat damaged), and m. 1 . The first of these teeth 2 is almost identical 
with the corresponding tooth of the specimen represented in plate XXXVA., fig. 1 : 
the carnassial is, however, as short as in the skull represented in plate XXXV., fig. 1, 
with its second and third lobes relatively small : its tubercle being broken makes its 
blade appear to extend considerably in advance of that former part, although it really 
does so about as much as in the specimen represented in plate XXXVA., fig. 3 : the 
tubercle seems partly aborted. The true molar is of the same length as in the skull 
represented in plate XXXV., fig. 1, but is considerably narrower antero-posteriorly ; 
and approximated to pm. 4 it is inserted by three roots and in position is like the 
corresponding tooth of the specimen represented in plate XXXVA., fig. 3. It is 
probable that the antero-posterior shortening of m, 1 in this specimen must only be 
regarded as another variation: its transverse diameter is 045, and the antero- 
posterior 0T9. 
In the Dublin Museum there is among the Siwalik fossils purchased from Dr. 
Beattie (No. 41) part of the left maxilla of a hysena, with the last three cheek-teeth. 
From the teeth of this specimen being precisely similar to those of the skull represented 
in plate XXXV., fig. 2, and from the shape of the fragment, it is believed that it is the 
missing part of that skull, which has been restored in the figure. 
In plate XXXV., fig. 5, there is given the outer view of a left upper carnassial 
of a Siwalik hysena, collected by Mr. Theobald in the Kangra district, now in the 
Indian Museum. The specimen belonged to a fragment of the maxilla of a young 
1 Pm. 3 appears set somewhat less obliquely than in the type skull, but this is mainly, if not entirely, due to the slightly 
different position of the specimens. 
2 This tooth in the specimen is viewed more from the outer side than in any of the other specimens ; the crushing to 
which the specimens have been subjected have thrown the teeth out of their proper inclination, so that it is impossible to 
figure them all in the same position.
