When the eggs of Pectinaria gouldii are centrifuged after the breakdown of the germinal vesicle, the cytoplasm is separated into three main layers, and between the centripetal layer and the middle transparent layer, there appears a distinct birefringent layer. When the centrifuged eggs are perfused with 3% hexylene glycol in sea water, the birefringent layer disappears completely, while the mitotic apparatus (MA) is enlarged and becomes more birefringent. The birefringent layer reappears after re-perfusion with normal sea water, accompanied with a decrease of the size of MA. The cause of birefringency of the layer is not clear but the layer is supposed to have some relation with the formation of mitotic apparatus. Simillar phenomena are observed also in Spisula eggs.
