When the tail of the medaka (Oryzias latipes) is amputated at the level of the dorsal and anal fins, these curve over the cut surface with subsequent regeneration of several fin rays between them. These new fin rays are always bigger than those of the anal and dorsal fins and although situated adjacent to the latter, they never contain pterygophores being in direct contact with the last vertebra and its spines (Fig. 1.B, C). In the loach (Misgurnus anguillicaudatus) regeneration of a new fin readily takes place even when the tail is cut close to the arms. In this case also, as in the medaka, urostyle (Duncker) and pterygophores do not develop. buit tne regenerated fin of this fish differs from that of the medaka in having no enlargement of the posterior end of the cut vertebra (Fig. 2.B, C, D)
