The evidence relating to the habitation in England at some distant period of a species of the section of the genus Felis represented by the Lynx, rests, up to the present time, upon a portion of a skull and a ramus of a mandible, which were discovered in a cavernous fissure in rocks of Permian age, in Pleasley Vale, Derbyshire. They were found by Dr. Ransom, who communicated an interesting paper descriptive of the fissure and its contents, to the British Association Meeting held at Nottingham in 1866, and the fragments were then referred to the Lynx of Northern Asia (Felis cervaria). Subsequently they were examined by Professor Boyd Dawkins, who, after carefully comparing the skull, jaw, and teeth, with the corresponding parts of other species of Lynxes, and also taking into consideration its geographical range, says, “that they may be referred with equal justice to the Lynx of Norway and Sweden” (Felis borealis).
