Summary

[edit]
Description Fig. 514.— Diagrams of the neuromeresin chordate embryos. Wanting in Amphioxus (A), they appear with increasing distinctness in Petromyzon (8), Squalus (C), and Chick (D). This evidence does not accord with the assumption that they are pre-chordate structures which appear transiently in vertebrate embryos.
