RHINOCEROS. 407 
There are two species in India, viz. RAinoceros Indicus and R. Sondaicus, 
the latter being the Javan species. 
For the following description of the former I have to thank Mr. J. 
Cockburn, who, with most unselfish kindness, kept back the article he 
was about to publish, and gave it to me to incorporate in this work. 
The following remarks on dentition are also his :**—

premolar in both Zzdicus and Sondaicus is a deciduous tooth, which is 
not usually replaced, and gradually drops out with age, but it may be 
retained till extreme old age. In the majority of cases it is either lost 
or worn down before the last molar is in wear. The incisors also vary 
greatly in the adult animal ; they are = the outer pair below being 
the formidable dagger-shaped tushes, with which they inflict the terrible 
gashes they can produce. The median pair lower are usually lost or 
absorbed by advancing age, having no functions, and the incisive tusks 
themselves are subject to very rapid wear, being often worn down before 
the animal has reached middle age. Occasionally A. /udicus has six 
incisors in the lower jaw (the normal number in other mammalia), and 
four in the upper, but this is very exceptional.”—/. Cockburn, MS.

Native NaMes.—Genda, Gonda, Ganda, or Genra, Hindi; Gor, 
Assamese. 
Hasirat.—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 moun- 
tainous 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 
* 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.,
