So long as the oocyte remains in the body-cavity of the worm, it contains a large germinal vesicle and no trace of asters or centrosomes; but, after it has been deposited in sea- water, a typical amphiaster with distinct centrosomes at either pole is developed. If the Qgg is not fertilized, the amphiaster.
