The vitelline cells in Gorgoderina attenuata produce two qualitatively distinct substances. One substance assumes the form of individual, dense, osmiophilic globules. Many globules are contained in a single vesicle. The other substance is an amorphous mass of medium density that completely fills a vesicle. Observations indicate that the dense, osmiophilic globules develop in association with a system of small, contiguous, ribosome‐free vesicles. It is suggested that this system of vesicles constitute a Golgi apparatus for these cells. The amorphous mass substance develops in vesicles which appear to be derived from endoplasmic reticulum. Close association between the amorphous mass vesicle and mitochondria are commonly observed.
