RHINOCEROS OF THE SUNDERBUNDS. 147 
* Philosophical Transactions”’ (1821, p. 271). On the present occa- 
sion I bring before the Society my notes on a young female of the 
Sondaic Rhinoceros (Rhinoceros sondaicus), which died in the mena- 
gerie of Mr. C. Jamrach, after having been in this country for a little 
more than half a year. It was only the skinned trunk which came 
into my possession. It is the nature of the mucous membrane of the 
small intestine which was certain to be of greatest interest; and this 
I am able to describe in detail. 
The individual under consideration measures, stuffed, 6 feet 2 inches 
from the tip of the nose to the base of the tail. The tail itself is a 
foot long, whilst the height of the animal at the shoulder is 3 feet. 
From the middle of the occipital crest, along the curve of the 
superior surface of the skull, to the tips of the nasal bones is 13} 
inches, the same measurement in adult animals being 22 inches. 
The single milk-incisor on each side of each jaw is still in place, as 
are all the milk-molars. The first true molar has not cut the gum; 
but its cap is seen within the bony alveolus. No traces of the other 
molars are visible. 
Mr. E. Gerrard lias kindly lent me the skull for examination. In Page 708. 
its base it exhibits the characteristic peculiarities of the species so 
clearly enunciated by Professor Flower,* the vomer being free behind 
- and developed into a tongue-shaped process ; the mesopterygoid fossa 
being expanded, and the free ends of the pterygoids everted at the 
same time that they are broad. No second combing-plate is present 
on the uncut first upper molar tooth. 
The animal is too young to be contrasted advantageously with 
Professor Peters’ drawing+ of Rhinoceros inermis, Lesson. I have, 
however, taken the opportunity of comparing that figure with the 
skulls of R. sondaicus in the College of Surgeons’ Museum, and fail to 
see that there are sufficient differences to justify specific differentia- 
tion. Professor Flower had previously done the same, and had arrived 
at a similar conclusion, as he found that even greater differences than 
those pointed out by Professor Peters are to be detected in individuals 
which are all undoubtedly of Indo-Malay origin. 
In skin-folding and surface-texture the Sunderbund and Javan Page 709. 
specimens agree exactly ; the young Sunderbund animal presenting a 
most striking uniformity in the size of the epidermic tuberculation, 
except in the gluteal region, where the boiler-bolt-shaped tubercles are 
somewhat larger than elsewhere. Along the back the scattered brown 
hairs, which spring from the yielding linear intertubercular surfaces, 
_ave also well developed.
