"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 tropical primeval forests.
"Here and there belts of Dhak (Butea frondosa) were found, and in favoured spots doubtless other tree jungle, but it is improbable that primeval forest has existed since the depression of the Indo-Gangetic plain."—J. Cockburn, MS.
The rhinoceros is supposed to be a very long-lived animal. Dr. Gray ('P. Z. S.' 1867. p. 1011) states on the authority of Mr. Blyth that a pair lived in the Barrackpore Park for forty-five years. They were exactly alike in size and general appearance; they never bred. There is no difference in the horns or form of the skull in the two sexes (Blyth, 'J. A. S. B.' vol. xxxi. p. 155).
