Period of gestation. —Seventeen or eighteen months, a single one being 
produced. 
Description. — Skin naked, except on the tail and ears. The shin is divided 
into shields on the shoulders, over the neck, the centre of the body, the rump 
and the thighs, and is studded with convex tubercles. The colour is blackish 
grey throughout. The horn is well developed in both sexes. It inhabits grass 
jungles ; never ascends the hills, has a preference for swampy ground and 
wallowing. It is quiet and inoffensive, but when wounded or driven will occa¬ 
sionally charge home. It can trot and gallop at a fair speed. The day is 
passed in sleep, the feeding time being morning and evening. Its principal 
food is grass. It is very long lived and its flesh is excellent. It is easily killed, 
and a bullet from any ordinary sporting rifle will drop it dead at once. The 
spot to aim at, for the neck shot, is about half way along and tolerably high 
up. The head shot, if successful, is a certainty, the shoulder shot should not 
be attempted unless with a large bore rifle.
