ZOOLOGICAL BULLETIN, VOL. 2 (CLASSIC REPRINT)

Excerpt from Zoological Bulletin, Vol. 2Later, during the first cleavage, similar filaments arose from the surface of the egg. They were especially well seen when occurring as stout, stiff - looking, radiating lines arising from the tops of certain remarkable papillae that frequently formed on the sides of the gaping cleavage furrow. As these small papillae armed with tufts of filose processes arose at certain phases in cleavage and then vanished, they suggested some such temporary interconnection of cells as occurs in certain echinoderms,1 but the filaments could not be followed from one cell to the other and seemed much too short to furnish any intercellular union by filose activity. In this connection it seems significant that the cleavage is of such a nature as to leave it doubtful, from surface views, whether the blastomeres actually separate entirely as in the echinoderms, or not.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
