e bony cores are also spiral, so
that in the dry skull the horn screws on and off. The colour of the
old males is deep blackish-brown, the back and sides with an abrupt
line of separation from the white of the belly; the dark colour also
extends down the outer surface of the limbs; the back of the head,
nape and neck are hoary yellowish; under parts and inside of limbs
pure white; the face is black, with a white circle round the eyes
and nose; the tail is short; the young males are fawn-coloured. The
females are hornless, somewhat smaller, and pale yellowish-fawn
above, white below, with a pale streak from the shoulder to the
haunch.

SIZE.--Length, about 4 feet to root of tail; tail, 7 inches; height
at shoulder, 32 inches. Horns, average length about 20 inches--fine
ones 22, unusual 24, very rare 26. Sir Barrow Ellis has or had a pair
26-1/2, with only three flexures; 28 has been recorded by "Triangle"
in _The Asian_, and 30 spoken of elsewhere, but I have as yet seen
no proof of the latter. The measurement should be taken straight from
base to tip, and not following the curves of the spiral. I have shot
some a little over 22, but never more. I believe, however, that the
longest horns come from the North-west.

This antelope is so well known that it is hardly necessary to dilate
at length on it; every shikari in India has had his own experiences,
but I will take from Sir Walter Elliot's account and Dr. Jerdon's
some paragraphs concerning the habits of the animal which cannot be
improved upon, and add a short extract from my own journals regarding
its love of locality:--

"When a herd is met with and alarmed, the does bound away for a short
distance, and then turn round to take a look; the buck follows more
leisurely, and generally brings up the rear. Before they are much
frightened they always bound or spring, and a large herd going off
in this way is one of the finest sights imaginable. But when at speed
the gallop is like that of any other animal. Some of the herds are
so large that one buck has from fifty to sixty does, and the young
bucks driven from these large flocks are found wandering in separate
herds, sometimes containing as many as thirty individuals of
different ages.

"They show some ingenuity in avoiding danger. In pursuing a buck once
into a field of _toor_, I suddenly lost sight of him, and found, after
a long search, that he had dropped down among the grain, and lay
concealed with his head close
