WATERBUCK (Wasserbok), the name of a large South African antelope (Cobus ellipsiprymnus) belonging to the subfamily Cervicaprinae, characterized by the white elliptical ring on the
Waterbuck. buttocks, and the general reddish grey colour of the long and coarse hair. They have heavily fringed necks and tufted tails, the bucks carry long sub-lyrate and heavily ringed horns, but the does are hornless. They seek refuge from pursuit in the water. The name is extended to include the sing-sing or defassa waterbuck (C. defassa), a widespread species, without the white ring on the buttocks, and represented by several local races, one of which is foxy red while a second is greyish. Both species equal in size the red deer. The smaller members of the genus Cobus (which is exclusively African) are generally called kobs. (See Antelope.)
