The Hb's of some Oncorhynchus and Salvelinus fishes inhabiting in Northeast Japan were analyzed by starch-gel electrophoresis with the following results. 1. Hb pattern of "suginoko", an Oncorhynchus fish, is not so fixed as in ordinary "yamame", and hence it may be said that "suginoko" is less differentiated in Hb evolution, compared to ordinary "yamame" as NAKAMURA et al.3) have proposed, it is reasonable taxonomically to classify "suginko" as one type of "yamame". 2. The theory that genus Salvelinus fishes in Japan can be broadly divided into "oshorokoma", Dolly Varden Salv. malma and "iwana", Japanese char Saly. leucomaenis including "amemasu", "kirikuchi", "kogi" and "tanburi", the theory initially presented by IMANISHI8) and later supported by the present author, both on the basis of the clines of some biological characters, were substantiated here by the analysis of Hb's from several Salv. fishes. Incidentally, "miyabe-iwana", a Salvelinus fish showed a unique Hb pattern, suggesting the occurrence of a kind of Hb evolution. 3. From analytical results with the Hb's from the river- and lacustrine-form salmonid fish as reported previously1, 2) and here, it could be said that with a few exceptions, there is a parallelism between the tendency of decrease in Hb components and the direction of evolution.
