Excerpt from book: The Metamorphosis of Echinoderms. Henry Bnry, ill. A., IM..S., Late Fellow of Trinity College, Cambridge. With Plates 3?9. Introduction. Aqassiz's view, put forward more than thirty years ago (1, p. 61), that the actinal and abactinal surfaces of Echinoderms (at least of Echinids, Asterids, and Ophiurids) are formed from the right and left enterocoel pouches ( water- tubes, as he calls them) respectively, has met with very general acceptance; but surprisingly little has been done to test it by modern methods. Agassiz's observations were, of course, made on the whole larvae, without any assistance from sections. Gotte (9) in 1876 applied the section method to Antedon, and found Agassiz's view to hold good there; yet, on the other hand, Ludwig (15) in 1882 failed altogether to trace this symmetrical arrangement of the enteroccels in Asterina, while he showed conclusively that Agassiz was mistaken in supposing that the left enterocoel gives rise to nothing but the hydrocoel. No one has ever attempted, so far as I know, to show how Holothurians can be included in Agassiz's scheme; and the conclusion of those who have studied their development has generally been (21, 31, 32) that in retaining the dorsal mesentery of the larva as a longitudinal mesentery in the adult (not a transverse one, as it is in Antedon, and should be on Agassiz'shypothesis) they exhibit a primitive approach to a worm-like ancestor. With a view to clearing up some of these differences of observation and opinion, I commenced in the spring of 1888 an examination of the metamorphosis of all available Echino- derm larvae, paying special attention to the behaviour of the mesentery, in the belief that this would afford an important clue to the difficult question of the origin of Echinoderms ...
