Whether D. jenmani shows the same peculiarity was not determined, on account of the failure to obtain the young embryo of this species; but as in its later development it corresponds very closely to the other species, it is highly probable that a suspensor is Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Carnegie Institution of Washington.
