Figure 4B also shows of the apical tuft. It is possible that the abnormalities observed in the seta sacs of older larvae (Fig. 4) may be due to the early action of the ion on the material des- tined to be incorporated into the 2d cell. The absence of any true cases of exogastrulation in these experiments is quite striking. As was noted above, most of the forms in which this abnormality has been obse

As was noted above, most of the forms in which this abnormality has been observed are marked by a type of gastrulation in which invagination plays a main.
