Saiga
in zoölogy, a genus of Bovidæ, with one species, S. tartarica, from eastern Europe and western Asia. They differ so much from all other antelopes that some naturalists have made them a distinct family. Also, any individual of the genus Saiga. They are about the size of a fallow deer, tawny yellow in summer, and light gray in winter; horns, found only in the male, less than a foot long, slightly lyrate and annulated.
