By means of vital dyes, a cellular migration from ecto- derm to entoderm has been demonstrated in correlation with the shift of gut potency from ectoderm to entoderm in the early blastoderm (Hunt, '37b), but there is "no evidence that the localization process itself is to be explained on the basis of a cellular migration" (Rvidnick and Rawles, '37).

Mouth Formation. Experiments on the stomodeal region of A. punctatum by Adams ('24, '31) showed that mouth invagination is dependent upon contact of the ectoderm with the underlying entoderm. Experiments by Balinsky ('47b) confirmed and extended the view that the entoderm acts as an in- ductor on the stomodeal ectoderm. Most of Balinsky's experiments were done on T. taeniatus embryos in late gastrula and early.
