NATURAL HISTORY OF SOUTH AFRICA 



It is horned ; the horns, although more slender 

 than those of the male, are longer. A peculiarity 

 of the horns of the female is their lack of symmetry. 

 Some have tips turning inwards, others the reverse, 

 one horn is longer or twisted differently to the 

 other, and so on. 



On the contrary, those of the male are quite sym- 

 metrical as a general rule.
