ns about the size of a shilling, and bearing much
resemblance to the heads of bolts by which the shield was riveted
to the body, and hence called 'boiler-bolt tubercules.' This shield
is often removed from the carcase of a slain rhinoceros as a trophy,
'and it is in its centre, but slightly low, that the fatal spot lies
which will take him in the heart' (_Pollock_).

"Between the scapular and the gluteal shields lies the abdominal
segment. It calls for no particular description, except that the
tubercles here are very much flatter and smaller than on either
segments three and four. They are here about the size of a four-anna
piece, and they seem to be crowded along the centre line of the body,
while the dorsal surface is nearly free from them, and smooth.

"We next come to the gluteal segment. It is in this portion that the
boiler-bolt tubercles attain their greatest development, some of
them being perhaps three-tenths of an inch high.

"The gluteal segment is laterally crossed by three ridges of skin.
The first, which is the only one indicated in the drawing, goes right
across the buttock. In some animals there is an indication of a second
below this, and about fourteen inches lower down a third, which only
goes about a quarter of the way across. The tail is almost concealed
in a deep groove, in which lie the perineum, &c. Both the front and
hind limb from the point at which they project from the body are
finely covered with reticulated skin, forming pentagonal and
hexagonal scales, very much as in _R. Sondaicus_, only much finer
and less prominent.

"The Indian rhinoceros has the same habit as the African species of
depositing its droppings in one spot till they form huge mounds,
which the animal levels with its horns. It is probable that this
rhinoceros was found throughout the plains of the N.W. Provinces in
unreclaimed spots as late as the fifth or sixth century. According
to the observation of Dr. Andrew Smith in South Africa these huge
pachyderms do not absolutely require for their support the dense
tropical vegetation we should think necessary to supply food to such
huge beasts. This gentleman saw over fifty of them in one day in an
open country covered with short grass and thorn-bushes about four
feet high. From the affinities of the fauna of the N.W. Provinces,
which are strongly African, it is probable that the plains of the
N.W. Provinces were rather covered with scrubby open jungles and
grass than with
