The tail has black hairs tipped with white on the upper surface and is all white on the underside. The sides are distinguishable from other Lepus species in that they are pure white. The rump and thighs are also white and lined with a few black hairs.
A median black line concealed by sooty, brownish, and white-tipped hairs divides the rump. The limbs are white, but their outer surface is stained a buffy color.
