HIMALAYAN IBEX. 
some three feet long, sweep back nearly to the haunches. It lives in very 
small herds and the bucks make the females do sentinel duty, and their vigi¬ 
lance is such that they are very rarely 
hunted with success. 
The Blue Buck ( Cephalopus pygmcea) 
is only about two feet in length, and but 
a foot in height. It is dark blue in color, 
and its two-inch horns are straight and 
closely ringed. Its color is such a pro¬ 
tection that it is seldom killed. It belongs 
to South Africa. It lives on the hillside, 
and moves about in herds of ten or twelve. 
It is remarkably swift and active. Its fore¬ 
head is tufted. 
The Sassaby, or Bastard Hartebeest 
{Damalis lunatus) , is reddish-brown, having 
a blackish-brown stripe down the middle 
of the face. It lives near the southern 
limit of the American tropical zone, and 
is always a welcome sight to the thirsty 
traveller, for its presence tells of water 
near at hand. It is much sought for its fiesh, which is held in high esteem. 
The Munni, Pied Antelope, White-faced Antelope, or Bontebok 
(Damalis pjyarga), is purplish, with black¬ 
ish-brown on the outside of the legs, and 
white upon the inside of the legs the 
haunches and the face. It is larger than 
the stag, and has a wealth of horns which, 
annulated and black in color, attain a 
length of a foot and a quarter. It is found 
in the region of the Cape of Good Hope. 
The Blaze Buck, or Bless Buck 
(.Damalis albifrons ), is a species closely 
connected with the nunni, which also have 
the blazed face, from which this species 
takes its name. It is South African in 
habitat. 
The Natal Bushbuck, or Rhoode- 
bok, or Red Buck ( CephalopJius nata- 
lensis ), lives a solitary life in the densest 
parts of the forests. It is about two feet 
high and wears straight, long-pointed horns. 
Its deep red color reflects the light and 
helps to conceal the animal. When 
mouflon {Ovis musimori). alarmed, it keeps moving its large ears 
and walks, as it were, on tip-toe. If a twig 
snaps, it stops at once in whatever attitude it may be, and then again, after 
this dramatic display, moves on with the same caution. If satisfied of the 
reality of the danger, it at once bounds away into the forest. It is yel-
