1) This research was undertaken to examine the developmental conditions in the reciprocal cross between Misgurnus anguillicaudatus (Cantor) and Moroco percnurus (Pallas). 2) The first large mortality occurred in the gastrula stage in Misgurnus anguillicaudatus ♀×Moroco percnurus ♂ and at the stage of head formation in Moroco percnurus ♀×Misgurnus anguillicaudatus ♂, and the second at the hatching in the both crosses. 3) The gills of these larvae have not the characteristic of Misgurnus anguillicaudotus but rather the feature of Moroco percnurus. 4) Times needed for hatching and numbers of myotomes disply the both the parental influences. 5) The larvae had melanophores of the intermediate pattern of parents in each cross and in the case yellow Misgurnus anguillicaudatus ♀×Moroco percnurus ♂ all expressed melanophores. 6) The larvae all produced edema. As to the maximum longevity, those in Misgurnus anguillicaudatus ♀×Moroco percnurus ♂ survived for 10 days and those in Moroco percnurus ♀×Misgurnus anguillicaudatus ♂ for 16 days. 7) In all the larvae blood-corpuscles could not be found with the exception of a few individuals in Misgurnus anguillicaudatus ♀×Moroco percnurus ♂.
