that yawn to receive them. One after another falls into the pit, and in this manner they perish 
by hundreds at a time. 
A very similar kind of trap, called the Hopo, is employed in Southern Africa, the walls of 
the inclosure being formed of trees and branches, and terminating in the pit of death. At the 
widest part the walls are about a mile asunder, and their length is about one mile. The pit at 
the extremity is guarded at its edges with tree-trunks, so as to prevent the sides from being 
broken down by the struggling animals in their endeavors to escape, and the plan is so suc- 
cessful, that sixty or seventy herd of large game are often captured in a single week. 
The flesh of the Ariel Gazelle is highly valued, and is made an article of commerce as well 
as of immediate consumption by the captors. The hide is manufactured into a variety of 
useful articles. The Ariel is a small animal, measuring only about twenty-one inches in height

Persian and other Oriental poets, is ascertained to be a different species from the Dorcas, and 
may be distinguished from that animal by the general dimness of the marking, and the dark 
brown streak on the haunches. Itis also known by the name of Anu, and DsHEREN. Several 
other species are now known to belong to the genus Gazella, among which we may mention the 
Mour of Western Africa, the AnpRA of Northern Africa, and the Korty, or KEveEt, of 
Senegal. The latter animal possesses no tufts of hair upon the knees. There is one animal, 
the Cuikara, or RAVINE DrEEr of India, which is worthy of a passing notice, because it is by 
some authors supposed to belong to the Gazelles, and by others to form a separate genus, as is 
the case with the arrangement of the British Museum. This animal is also known under the 
titles of CHouKA, Goar ANTELOPE, and KALSIEPIE, or BLACK-TAIL. 
THE SPRING-BOK derives its very appropriate title from the extraordinary leaps which it 
is in the constant habit of making whenever it is alarmed. 
As soon as it is frightened at any real or fancied danger, or whenever it desires to accelerate 
its pace suddenly, it leaps high into the air with a curiously easy movement, rising to a height 
of seven or eight feet without any difficulty, and being capable on occasions of reaching to a
