• A. Tail quite short. No Gazelline face-markings. Females without horns.
• a. Horns strongly curved backwards. Skull 7 in. or less in basal length.
• a¹. Horns not hooked at tip. (Tibet.)  82. G. picticaudata.
• b¹. Horns hooked at tip. (Mongolia.)  83. G. przewalskii.
• b. Horns but little curved backwards, not hooked at tip. Skull about 9 in. in basal length. (N. China.)  84. G. gutturosa.
• B. Tail of average length, its terminal half generally more or less crested with black. Face-markings present. Females (except in G. subgutturosa) with horns.
• a. Upper part of face white (at least in old age), interrupting the central facial band.
• a¹. No horns in female: size larger. (Central and Western Asia.)  85. G. subgutturosa.
