347—170 INDIAN TERTIARY AND POST-TERTIARY VERTEBRATA. 
right femur of a large feline, collected by Mr. Theobald in the Siwaliks of the 
Punjab. This bone is relatively somewhat smaller than the humerus and ulna 
described above, and indicates an animal about equal in size to a rather small tiger. 
It is readily distinguished from the femur of the lion, by the nearly cylindrical form 
of the middle of the shaft ; and in this respect is more like the femur of the tiger, 
although the lower part of the anterior surface is more flattened. On the posterior 
surface the intercondylar notch is relatively wider than in the tiger, and more like 
the same part in the lion ; the inner border of the external condyle is also placed 
more obliquely than in the tiger, in nearly the same manner as in the lion. The 
trochlear surface for the patella is narrower and deeper than in the lion, and more 
like that of the tiger. It is not improbable that this bone may have belonged to the 
smaller species of Machcerodus: 
In the British Museum there are ten specimens of the distal extremity of the 
femur of large felines from the Siwaliks, and one from the Narbadas. The 
dimensions of the largest specimen of the former (No. 40,527) are compared below 
with those of a femur of the cave-lion in the same collection (No. M. 270), and of a 
large African lion ; vis. :

In the Siwalik bone the anterior surface above the condyles is more angulated, and 
less flattened than in the lion, or in the smaller Siwalik femur described above. 
From its large size it is probable that the present specimen belonged either to F. 
cristata, or M. palceindicus. 
Patella. — The patella represented in pi. XLV., fig. 4, was obtained by Mr. 
Theobald in the Siwaliks of the Punjab ; and indicates a feline nearly as large as 
the cave-lion. In its elongated form this bone is more like the patella of the lion 
than that of the tiger ; but its posterior surface is more convex than in either ; the 
patella of the tiger coming nearest in this respect. This bone not improbably 
belonged either to F. cristata or M. palceindicus. 
Calcaneum. — The two calcanea represented in pi. XLV., figs. 6 and 7, were 
obtained by Mr. Theobald from the Siwaliks of the Punjab. The former, belonging 
to the right side, agrees almost exactly in form and size with the corresponding bone 
of F. pardus ; and may have belonged to the same species as the mandible 
represented in pi. XLIII., fig. 4. The latter, belonging to the left side, is of nearly 
the same size as the calcaneum of the lynx ; and may possibly have belonged to the 
species of which the mandible is represented in pi. XLIII., fig. 7 ; or to one of the 
genera of primitive cats. 
Scapho-lunar. — From the pleistocene Jamna beds of the Banda district Mr. J. 
Cockburn 1 has obtained a nearly perfect specimen of a right scapho-lunar, indis-
