Ovariole of B. amphitritc with RNA in the cytoplasm of oogonia (og), immature oocytes (io), and between the yolk droplets (yd) in mature oocytes (mo) (methyl-green pyronin Y, scale 50 /u). FIGURE 3. Ovariole of B. cbuniciis showing SH- and SS-positive yolk droplets (yd) and negative cytoplasm of immaure oocytes (io) (thioglycollic reduction followed by DDD reaction, scale 50 M). FIGURE 4. Ovariole buds (ob) with amorphous material (am) of B. cbiirncus along an ovarian duct (od) (Azan stain, scale 50 M)- of the ovariole which has become a compact structure. The oogonia are observed in frequent mitoses. In even more elongated ovarioles, small immature oocytes are present in the periphery with the string of oogonia in the center (Fig. 6). As.
