This volume provides systematic accounts of members of the Antilopinae, arranging genera and species entries with careful descriptions of external form, skull and horn morphology, dentition, measurements, and sexual and age variation. Geographic range notes and comparative remarks clarify relationships and diagnostic characters. Numerous plates and text figures illustrate heads, horns, skulls, skins, and typical attitudes, and individual species accounts cite specimen evidence and synonymy where relevant, enabling identification and comparison across gazelles, saiga, chiru, springbuck, gerenuk, dibatag, and related antelopes.
