CHAPTER XVI 



THE WATERBUCKS AND REEDBUCKS 



Subfamily Kobince 



The members of the Kobince cover a wide range in body- 

 size, from the large, stately waterbucks to the small rock 

 reedbucks. The group includes the waterbucks, lechwis, 

 kobs, reedbucks, and rock reedbucks and is characterized 

 by low withers, absence of the anteorbital gland, and the 

 presence of horns in the male only. The horns are usually 

 curved forward and ringed for the greater part of their 

 length. The skull is without anteorbital fossa but shows a 

 large lachrymal-nasal sinus on the sides of the snout. The 

 range of the subfamily covers the continent of Africa from 

 the Cape region northward to the southern edge of the 

 Sahara Desert in the Senegal, Lake Chad, and Abyssinian 

 regions. This subfamily has been usually known among 

 naturalists as the Cervicaprincs ; but, owing to the genus 

 Cervicapra having been found untenable, the genus Kohus, 

 being the best known and most typical, has been selected 

 as the type.
