A large South African antelope (Strepsiceros kudu). The
   males have graceful spiral horns, sometimes four feet long. The general
   color is reddish or grayish brown, with eight or nine white bands on
   each side, and a pale dorsal stripe. The old males become dark bluish
   gray, due to the skin showing through the hair. The females are
   hornless. Called also nellut.
