Abnormal Horns. 
Occasionally, cow eland are found with one or both horns 
abnormally formed; such abnormal horns being long and nearly 
straight, with a triangular cross-section. Such a pair, measuring 30 inches in a 
straight line, were described a few years ago under the name of Antilope triangul¬ 
aris, and were supposed to indicate an extinct species of antelope, which was 
subsequently referred to a new genus. 
The magnificent animal known as the Derbian eland (0. 
derbianus), replaces the common species on the West Coast in the 
districts of Angola and Senegambia. It is considerably larger than the southern 
and eastern form; and the bulls have a large dark brown mane and much finer 
horns. The horns of the cows are, however, relatively small. Male horns have 
been measured of 34J inches in length.

Kudu. 
Genus Strepsiceros. 
The graceful and beautifully marked antelopes known as kudu, of which 
there are likewise two species, 
are distinguished from eland 
by the absence of horns in 
the female, and by the cork¬ 
screw - like spiral formed by 
those of the male, as well as 
by the much shorter tail, 
which does not reach the 
hocks. The horns are char¬ 
acterised by the great develop¬ 
ment of the front ridge, and 
rise from the skull at an 
obtuse angle to the plane of 
the face. The neck is maned, 
and the throat may be fur¬ 
nished with a fringe of long 
hair. The body is marked 
with narrow vertical white 
stripes descending from a white 
line on the back; and there 
is also a white chevron on the 
face, together with white spots 
on the cheek, and splashes of 
the same colour on the throat 
and limbs. The hoofs are 
short.
