antelope harmonized well with the dry landscape, and they 
were more difficult to make out than the hartebeests. 
These eland are said speedily to leave a district if they 
are harassed by hunters. They wander far, their wandering 
being sometimes seasonal and sometimes due to individual 
vagaries. It is said that in the rainy season, when the grass 
is thick and tall, they are often killed by lions, which are 
then able to get so close as to seize them by the head; but 
that in the dry season few are killed by lions because then 
the big cat can rarely make his rush from such a short dis¬ 
tance as to insure a grasp of the head, while the quarry is 
so huge and strong that if seized elsewhere it can generally 
break away. 
The giant or Nile Derby eland differs from the typical 
race from the Senegal region chiefly by lighter color in the 
bull, the females of the two races being quite similar in color 
and size. In the Derby eland the old bull has the neck 
covered by long black hair, but in the Nile race the lower 
sides and throat lack the long black hair; this part being 
covered by thin grayish hair like the sides. The material 
available of the Derby eland, however, is very scanty. The 
only specimens examined were a male and female skin at 
the British Museum. The Nile race is much better repre¬ 
sented in collections and it is quite certain that uniformly 
black-necked bulls such as the Derby eland at the British 
Museum do not occur in the Nile district. The most 
heavily maned bull examined is that shot by Colonel 
Roosevelt in the Lado. The long black hair covers the 
whole nape in this specimen and extends half-way down on 
the sides. The younger bull from the same locality shows 
only a narrow dorsal mane on the nape. 
The old bull shot by Colonel Roosevelt has the ground- 
color of the body vinaceous-buff which becomes on the shoul¬ 
ders and the hind quarters ochraceous-buff and on the lower 
sides merges gradually into the cream-buff of the under-parts. 
A white dorsal stripe of irregular width extends from the black
