Abstract

The ultrastructure of the nuclei in the ovarian follicular cells has been examined in the lizards Acanthodactylus scutellatus hardyi, and Eremias brevirostris. During certain growth stages, the nuclei of the intermediate and the pyriform cells become large and conspicuous, and usually contain numerous morphologically variable nucleoli. The latter may be nucleolonemal, compact, ring-shaped, "filamentous", "fine-filamentous", "amorphous" or "course-granular" in type, and the number and type in each nucleus seems to be related to the developmental stage. The type of nucleolus may indicate different phases of activity in the nucleus and may also suggest an association with the production of different types of RNA.
