A light- and electron-microscopic investigation of gametogenesis in Typosyllis pulchra. (Berkeley and Berkeley) (Polychaeta: Syllidae). II. Oogenesis

Oogenesis in Typosyllis pulchra begins with a short proliferative gonial phase. Gonial clusters, consisting of six to eight syncytial sibling cells, are surrounded by gonial peritoneum and are eventually liberated into the coelom. At about the same time as the onset of the coelomic phase, one gonial...
