examined many fresh English rabbits, and the large collection of skins in
the British Museum from various countries, and all have the upper surface
of the tail and the tips of the ears clothed with blackish-grey fur; and
this is given in most works as one of the specific characters of the
rabbit. Now in the seven Porto Santo rabbits the upper surface of the tail
was reddish-brown, and the tips of the ears had no trace of the black
edging. But here we meet with a singular circumstance: in June, 1861 I
examined two of these rabbits recently sent to the Zoological Gardens, and
their tails and ears were coloured as just described; but when one of their
dead bodies was sent to me in February, 1865, the ears were plainly edged,
and the upper surface of the tail was covered with blackish-grey fur, and
the whole body was much less red; so that under the English climate this
individual rabbit had recovered the proper colour of its fur in rather less
than four years!

The two little Porto Santo rabbits, whilst alive in the Zoological Gardens,
had a remarkably different appearance from the common kind. They were
extraordinarily wild and active, so that many persons exclaimed on seeing
them that they were more like large rats than rabbits. They were nocturnal
to an unusual degree in their habits, and their wildness was never in the
least subdued; so that the superintendent, Mr. Bartlett, assured me that he
had never had a wilder animal under his charge. This is a singular fact,
considering that they are descended from a domesticated breed. I was so
much surprised at it, that I requested Mr. Haywood to make inquiries on the
spot, whether they were much hunted by the inhabitants, or persecuted by
hawks, or cats, or other animals; but this is not the case, and no cause
can be assigned for their wildness. They live both on the central, higher
rocky land and near the sea-cliffs, and, from being exceedingly shy and
timid, seldom appear in the lower and cultivated districts. They are said
to produce from four to six young at a birth, and their breeding season is
