In fig. 33 a, which passes through the central region of the embryonal ecto- derm (e.ect.), the covering trophoblast has disappeared and a slight depression is present on the surface of the ectodermal mass, the cells of which are now assuming a columnar arrangement. The covering trophobla3t (c.tr.) is still present over the more peripheral portion of the embryonal ectoderm (figs. 33 6 and 33 c).
