Eyestalks were removed on successive days from 7 animals • — •. all of which died at ecdysis; 8 walking legs were autotomized from 15 animals D — D. The animals were housed in individual bottles and observed until ecdysis 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 Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
