The purpose of this study was to clarify the early development of the bursa of Fabricius in Japanese quails. The thirty two quail embryos used in this study were mainlyfrom the 41/2 to the 9th days of incubation. The bursae were investigated histologically, histochemically and by scanning electron microscopy. The findings obtained in this study are as follows. 1. By the 41/2 and the 5th days of incubation, the bursal anlage consisted of proliferated urodeal epithelium. The mitoses occured more abundantly in endodermal epithelium of bursal anlage than in ectodermal epithelium. The degenerating product-like granules were found in ectodermal epithelium of bursal anlage. From the facts described above, the authors suggest that bursal epithelium derived from endodermal (urodeal) epithelium. 2. The bursal lumen is formed by coalescence of vacuoles in the bursal anlage. 3. The bursal membrane which was observed in the bursal anlage on the 8th day of incubation, was used as a landmark between the bursal endodermal portion and the ectodermal portion. 4. At the 9th day of incubation, the bursal lumen was established by disappearance of the bursal membrane.
