The bones of Pleistocene mammals and birds, a list of some of which is given below, were found in a small cave in an outlying part of the Forest of Dean, close to the river Wye, where it is flanked by steep and wooded hills that rise abruptly from either bank. At short intervals along the sides of these hills limestone cliffs and boulders stand out bare and white among the surrounding trees. The slopes below are strewn, and in places completely covered, with pieces of rock of all sizes that are continually becoming loosened and fall from the outstanding crags above, in which are numerous cracks, holes, and caves, the last, as a rule, being only of small size.
