as the genera recognised in other families, and indeed more so 
than in many. 
The geographical range of the Great Indian Rhinoceros would 
appear to be at present restricted, or very nearly so, to the tarai , 
an unhealthy marshy tract at the foot of the Himalaya, skirting ! 
the territories of JSTipal, Sikhim, and Bhotan. As remarked by an 
experienced naturalist, Dr. Jerdon, in his Mammals of India, this 
animal “ is more common in the eastern portions of the tarai than : 
the western, and is most abundant in Assam and the Bhotan 
Dooars. I have heard from one sportsman/’ he adds, “ of its 
occurrence as far west as Rohilkund, but it is certainly rare there 
now, and indeed along the greatest part of the Mpal tarai; and, 
although a few have been killed in the Sikhim tarai, they are 
more numerous east of the Teesta river.” Dr. Jerdon suspects 
that it has crossed the great river Brahmaputra, and that it may be 
found in some of the hill ranges to the east and south of that river. 
From the dimensions given of a pair killed in the Garrow hills, 
in the territory indicated, we conclude that such must be the case, 
and that both of the One-horned Rhinoceroses are there met 
with ; but from recent investigations it would appear that from 
thence southward, it is completely replaced by the It. sondaicus, a 
smaller kind, which has generally been supposed to be peculiar to 
the island of Java. 
The difference between these two species of One-horned Rhino- 
ceros is not sufficiently striking to be noticeable by an ordinary 
beholder, unless perhaps he might chance to have the rare oppor- j 
tunity of comparing the two together ; and thus there are sports- 
men who have killed both species in their respective haunts, but 
have failed to discriminate them apart, considering the smaller 
kind to be merely not fully grown. The R. sondaicus is about (or 
almost) a third less in size than the R. indicus , and its coat of mail 
is much the same, except that the tubercles on the hide are con- 
siderably smaller and of uniform size throughout, and (at least in 
the young animal) the polygonal facets of the skin have a few 
small bristles growing upon a depression in the centre of each of 
them. One marked distinction at all ages consists in this, that 
the strong fold or plait at the setting on of the neck, which is 
continued across the shoulders in the smaller species, or R. son- 
daicus , is not continued across in the larger one, or R. indicus, but
