At x is seen a protruding bit of the portion of the respiratory trees retained within this half animal. The characteristic puckering of the surface at the division area is also indicated. The evidence that the regeneration found occurring under natural conditions results from the self-division of adult holothurians, involves two considerations. The first concerns (a) the relative size of the regenerating animals, and (b) the relative frequency of anterior and posterior ends noted as regenerating. The second has to do with direct observations of 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 Bermuda Biological Station for Research.
