Abstract
So far as I am aware, the extrusion of nucleolar material into the cytoplasm has not been recorded for the female germ-cells of Lumbricus or any other earthworm. In this connexion, Harvey1 remarked that in the nuclei of the “nearly ripe oocytes there may occur little droplets of material, similar in reactions to the plasmosome. They may be lying on the surface of this body, or may be entirely separate. Occasionally they are seen on the nuclear membrane, but never outside it. This may point to extrusion of nucleolar fragments, but only on a very small scale and never into the cytoplasm”. Gatenby and Nath2 observed that: “Neither Harvey nor the present writers have found any satisfactory evidence of nucleolar emission in Lumbricus”.
