The other species are generally brownish gray in summer and paler in winter. Both have a white rump patch, but that of P. picticaudata is continuous, whereas that of P. przewalskii is divided by a median line of darker color.
All species have white underparts.
The horns, present only in males, are about 200-250 mm long. The backward deflection of the horns is not as conspicuous in P. gutturosa as in the other species. The horns of P. przewalskii are curved in two places, with the points turned inward, while the horns of P. picticaudata are curved in only one plane. These gazelles are found in dry grassland at elevations of up to 5,750 meters. P. picticaudata is a wary and swift animal that scrapes out a bedding place in the ground and feeds in areas of scant vegetation.
