1) Behavior of periblast nuclei in the morula and the blastula stages of a freshwater teleost, the medaka, Oryzias latipes was observed in vivo and in sections. 2) They first appear in the early morula, 64-cell stage as free nuclei in the periblast. 3) They increase synchronously and mitotically until the blastula stage. 4) Their synchronism lasts longer than that of the division of blastomeric nuclei, probably because of their rather even environmental conditions compared with that of blastomeres. 5) Their mitotic division ceases at the blastula stage, suggesting a disturbance by the epibolic movement.
