Inside this fold is a space, connected at first with the archenteron, but soon the cavity of each side is cut off by a growing together of the opening into the archenteron and is henceforth known as a coalom1 or body cavity. Each ccelomic space has two walls, one toward the ectoderm, the somatic layer, the one toward the entoderm being the splanchnic layer (figs. 5 and 6). The mesoderm arising in this way and bounding the ccelom is called mesothelium to distinguish it from another kind—the mesen- 1A ccelom formed in this 'way is an enterocoale. Usually the ccelomic walls arise as a solid mass of cells from the corresponding region, which later splits internally, forming a schizocosle.
