In all the skulls of the large lop-eared rabbits, the supra-orbital plates
or processes of the frontal bones are much broader than in the wild rabbit,
and they generally project more upwards. In the zygomatic arch the
posterior or projecting point of the malar-bone is broader and blunter; and
in the specimen, figure 8, it is so in a remarkable degree. This point
approaches nearer to the auditory meatus than in the wild rabbit, as may be
best seen in figure 8; but this circumstance mainly depends on the changed
direction of the meatus. The inter-parietal bone (see figure 9) differs
much in shape in the several skulls; generally it is more oval, that is
more extended in the line of the longitudinal axis of the skull, than in
the wild rabbit. The posterior margin of "the square raised platform"
(4/25. Waterhouse 'Nat. Hist. Mammalia' volume 2 page 36.) of the occiput,
instead of being truncated, or projecting slightly as in the wild rabbit,
is in most lop-eared rabbits pointed, as in figure 9, C. The paramastoids
relatively to the size of the skull are generally much thicker than in the
wild rabbit.
