Pygarg

Easton's Bible Dictionary (1897)

Heb. dishon, “springing”, (Deut. 14:5), one of the animals permitted for food. It is supposed to be the Antelope addax. It is described as “a large animal, over 3 1/2 feet high at the shoulder, and, with its gently-twisted horns, 2 1/2 feet long. Its colour is pure white, with the exception of a short black mane, and a tinge of tawny on the shoulders and back.”, Tristram’s Natural History.

Smith's Bible Dictionary (1863)

occurs, (14:5) in the list of clean animals as the rendering of the Heb. dishon, the name apparently of one species of antelope, though it is by no means easy to identify it.
