The coelom is not present as a body-cavity, but is in the adult only represented by the cavities of the gonads and those of the nephridia. The actual body-cavity is a venous blood-space which thus contains blood and belongs to the l)lood-vascular system. Hence, as in the lobster and the cockroach, it leads directly into the dorsal heart by paired ostia or valves. The heart is itself a long tube lying dorsally, extending nearly the length of the body. It is surrounded by a pericardial simis, as in the 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 Masterman, Arthur Thomas; Parsons, John Herbert, Sir, 1868-1957, donor; S.
