Some workers have noted that in some lizards the broken vertebra is either resorbed or comes away with the scab (Bryant & Bellairs, 1967; Bellairs, 1969; Cox, 1969). This is not necessarily the case with L. guichenoti for although the autotomized vertebra is not visible in the specimens depicted in Figures 2 and 3, it is clearly visible in Fig. 7 and has not appeared to impede regeneration. Shortly after the end of the latent period, (approx. six days) the ependymal tube becomes noticable as an outgrowth from the broken end of the spinal cord. It is derived mainly from the ependymal epithelium which lines the cavities of the central nervous system (Bellairs, 1969). Its tip becomes closed off to form a small sac (the ependymal sac). The tissues around the ependymal sac begin to revert to a condition resembling embryonic mesenchyme (the blastema) (Bellairs, 1969). 294 Aust. Zool. 20(2), 1979.
