The tip of the colony, and therefore the anal aspect of thepolypide, is to the right in all cases. All figures X 410. Fig. 21. Stage of Figure 37 (Plate IV.). Few nuclei in central region. Fig. 22. Shows rapid growth of bud, chiefly at neck of polypide. The two innercell layers are about to separate to form the common cavity of atriuma
