elves are subject to very rapid wear, being often worn down
before the animal has reached middle age. Occasionally _R. Indicus_
has six incisors in the lower jaw (the normal number in other
mammalia), and four in the upper, but this is very exceptional."--_J.
Cockburn_, MS.

[Footnote 30: There are some interesting notes on the dentition of
the rhinoceros, especially in abnormal conditions, by Mr. Lydekker
in the 'J. A. S. B.' for 1880, vol. xlix., part ii.]

NO. 429. RHINOCEROS INDICUS.
(_Jerdon's No. 212_).

NATIVE NAMES.--_Genda_, _Gonda_, _Ganda_, or _Genra_, Hindi; _Gor_,
Assamese.

HABITAT.--Himalayan Terai, from Central Nepal to the extreme eastern
corner of the valley of Assam.

"About three centuries ago this animal existed on the banks of the
Indus. The Indian rhinoceros inhabits by preference heavy grass
jungle, rarely entering forest. In this respect it differs from its
ally _Sondaicus_, which is a forest-loving species, and even
frequents mountainous countries. It is still numerous in the mighty
grass jungles which extend along the foot of the Eastern Himalayas
from their slopes to the banks of the Brahmaputra. It is yearly
becoming more scarce in the Nepal Terai, but is found there from
Rohilkund to the Bhootan Doars."

DESCRIPTION.--The accompanying outline sketch, taken from _Nature_
for April 1874, will give a better idea of the animal than a mere
verbal description:--

[Illustration: _Rhinoceros Indicus_.]

"For convenience of description I will divide the body into five
segments--the head, the cervical, the scapular, the abdominal, and
the gluteal. At the junction of the head with the neck is a large
deep collar or ruff or fold of skin, which gives a very peculiar
appearance to the animal. Behind this is a second similar but smaller
ruff, which does not hang so low down from the throat as the first.
On the dorsal surface it transversely crosses the nape. It is then
continued down angularly to about the centre of the anterior edge
of the scapular shield, where it forms an obtuse angle with its
posterior but major half. It is at the point where it forms this angle
that it gives off what I call the cervical fold, which forms the
boundary of the top front edge of the scapular shield, but is lost
at a point in the shoulder nearly over the centre of the fore limb.

"The scapular shield is a thick cuirass-like plate of skin, studded
with round projectio
