As the embryo and the yolk-sac at first grow more rapidly than the connecting re- gion between them, this region is apparently constricted and becomes the yolk- stalk, or vitelline duel. At either end the entoderm comes into contact ventrally with the ectoderm. Thus there are formed the pharyngeal membrane of the fore- 168.
