exceeds 4% feet and is often less; the weight is about 1 ton. 
The maximum width of the forefoot in big specimens is about 
9 inches; the central toe-nail occupies 3% inches of this. 
This Rhinoceros is reputed to be much stronger and more 
agile than sondaicus. The period of gestation is reputed to last 
only about 7 months, a statement which requires checking, con- 
sidering that that of unicornis is known to be nearly three times 
as long. 
The species is found through the Malay Peninsula, to Siam 
and Assam up to 6000 feet. It is present on Sumatra and Borneo 
but not on Java. The form found in southwest Burma has been 
distinguished by the name lasiotis (broad-eared). It likes moist 
shaded hilly country, the steeper the better, and is generally 
solitary, or a bull and cow may be together. It frequently makes 
wallows in the stream beds. When enjoying its wallows, it makes 
a low humming or buzzing sound. The food consists of twigs 
and branches and a species of bamboo. In the dry season it may 
eat figs and mangos or other fruits also; thus, it is a good 
distributor of mango seeds. Formerly it was found in the low- 
lands as well as among the hills, but is now almost as scarce 
as R. sondaicus. 
The Greater One-horned Rhinoceros, Rhinoceros uni- 
cornis, rapidly becoming extinct, enters our area only at the 
eastern end of its range near the southern foot of the Hima- 
layas and eastward into Assam. Formerly it occurred over much 
of peninsular India. The skin of the sides is covered with rivet- 
like flattish tubercles, particularly on the fore and hind quarters. 
The heavy skin fold in front of the shoulder does not extend 
over the neck to meet the one omthe other side, as in R. son<- 
daicus. The horn is sharply conical and often about 6 inches 
high. Unusually large horns measuring 24 inches around the 
curve have been recorded. 
This Rhinoceros is a denizen of the vast areas of grass, 
growing from 8 to 20 feet high, that cover much of the unculti- 
vated parts of the alluvial plains of northern India, including
