SIWALIK AND NARBADA CARNIVORA. 
55—232 
anterior talon of the Indian form is smaller, though in profile the two appear very- 
similar. The two are further distinguished by pm. 2 -having a single fang in H. 
insignis, and two fangs in the Punjab form. The Spanish Hycenarctos is too 
imperfectly known for certain specific determination : the carnassial has, however, a very 
large internal tubercle like the present species ; but its anterior talon seems to be larger. 
As the present species cannot be identified with either of the other named species, it is 
entitled to a separate name, and the name II. punjabiensis is accordingly proposed for it. 
Distribution. — The remains described above, which, with one exception, came 
from the Punjab, are all that can be referred to the present species : the one exception, 
the specific determination of which is doubtful, came from Sind. From the occurrence 
of the remains of this species in the Punjab and Sind alone, and of those of H. 
sivalensis in the more easterly Siwaliks it is possible that the two species were limited 
in their range. In other species there are not wanting signs of similar limits in the 
range of the Siwalik carnivores. 
Species 3. Hyaenarctos paiaeindicus, n. sp., nobis. 
History. — On pages 103-4 of the Xlth volume of the “ Records ” mention is 
made of the maxilla of a Hycenarctos specifically distinct from H. sivalensis , for 
which the name U. palceindicus is proposed : that specimen, with some others, forms 
the subject of the present notice. 
Maxilla. — The maxilla mentioned above is represented in figure 1 of plate XXX.: 
it belongs to the right side, and contains the last three cheek-teeth ; and was obtained 
by Mr. Theobald from the Siwaliks of the Punjab. The teeth are perfect, with the 
exception of the summit of the first main lobe of the carnassial, and have been but 
very slightly abraded by wear. The carnassial (pm. 4) is constructed on the same 
general plan as the corresponding tooth of the two preceding species, but is shorter 
and wider ; its inner tubercle and anterior talon being largely developed. From the 
form of the alveolus of one of the specimens of Dinocyon hemicyon figured by Prof. 
Gervais 1 it seems that the carnassial of that species (which in the form of its true molars 
connects the present species with that genus) was constructed on the Hycenarctos type, 
having (as is seen from the position of the inner fang) a large internal tubercle : 
the step from this type to the carnassial of Cephalogale , 2 in which the tubercle, though 
confluent with the blade, is yet large and placed opposite the first lobe of the blade, 
is but small ; and the latter leads on to the carnassi,al of the true dogs, in which the 
tubercle is very small, and placed at the antero-internal angle of the crown. 
The first true molar (m. 1) of the specimen under consideration differs from the 
corresponding tooth of both the preceding species by being relatively shorter, and by 
the internal angles being more rounded off : in both these respects H. sivalensis is 
nearer to the present specimen than is H. punjabiensis. The specimen is also marked 
by the greater prominence of the outer lobes and the inner ridge ; the latter showing a 
distinctly marked cingulum on its inner side, which is entirely wanting in H.
