SIWALIK AND NARBADA CARNIVORA. 
57—234 
The small fragment of the external surface of the maxilla that still remains 
attached to the specimen, though too imperfect to afford any satisfactory figure, 
shows that the skull must have differed very considerably from that of II. sivalensis, 
or II. punjabiensis . . In both those species the external surface of the maxilla extends 
a considerable distance above the anterior root of the zygoma with but a very slight 
degree of inward inclination, indicating the straightness of the facial profile in both. 
In the present specimen, on the contrary, the maxilla is suddenly bent almost 
at a right angle at the zygomatic root, indicating that the facial profile must 
have been suddenly angulated at the orbit, in much the same manner as in Ursus 
spelceus. 
Distinctness, of species . — The foregoing comparisons leave no doubt that the 
maxilla under consideration belongs to a species distinct both from H. sivalensis and 
H. punjabiensis ; and as the specimen presents no marked resemblance to II. insignis 
or to the Hycenarctos of the English Crag it may be safely referred to a new species, 
for which the name palceinclicus may be adopted. The general resemblance of the 
teeth to those of the more typical species of Hycenarctos is so close that the species 
may, at all events provisionally, be referred to the same genus. It affords a marked 
step from the more bear-like typical species in the direction of the more dog-like 
Dinocyon. 
Upper canine , Whicli may belong to this species . — In figure 3 of plate XXX. there is 
represented a canine tooth of an ursoid animal obtained by Mr. Theobald from the 
Siwaliks of the Punjab (Ind. Mus. No. D. 11). From its highly curved form this 
tooth very probably belongs to the upper jaw, and if so, to the right side. The 
summit of the crown has been broken off, but the portion remaining shows that this 
was sub-circular, with a partially flattened posterior surface, bounded by a ridge at the 
postero-external angle. The tooth is less compressed than the canine of Ursus , and 
is more like that of Hycenarctos sivalensis , but much smaller, and with a more regular 
section: it lacks the marked flattened inner face of the canine of H. punjabiensis. 
Under these circumstances it is not impossible that it may belong to the present 
species. The profile of the whole tooth strongly resembles that of the canine of 
Dinocyon, 1 but the section of the crown is less- elliptical. The antero-posterior 
diameter of the base of the crown is O' 92, and the transverse O’ 87 inch. 
Mandible which may belong to the present species . — In figures 2 and 3 of plate 
XXXI. there are represented two, probably associated, fragments of the mandible of a 
species of Hycenarctos obtained by Mr. Theobald from the Siwaliks of Jabi in the 
Punjab, which may belong to the present species. The first specimen (fig. 2) is a 
part of the left ramus, containing pm. 4 and mTT ; the second (fig. 3) is from 
the opposite side, and contains m. 2. The dimensions of these specimens are 
compared below with those of the corresponding teeth and jaw of H. punjabiensis,
