Ability of regeneration of the hind limbs in newly metamorphosed toadlets of Bufo regularis Reuss was comparatively better at the knee joint level than at mid shank level or even at more distal levels; shank and ankle in the same stage and species. Histogenesis revealed the formation of a massive cartilaginous condyler capover the femur stump. Other cases which showed better regeneration restored part up to about half of the shank region or only the base of the shank with/without ill-formed knee joint, reaching 40% of the cases in the amputation series and 38% in the disarticulation series. One or more chondrifying centres, in regenerates of the latter series recall signs of organization. It is suggested that the mechanical stress caused by the disarticulation process evoked progressive histological change in favour of better regeneration. Histogenesis during the early post-operation days of the two types of experiments (amputation & disarticulation) and role of stump tissues with paucity of muscles at that level, are discussed.
