Immediately after preceding stage yolk beginning to shrink, and at this stage represented by only a fragment showing yellowish through the body wall. Embryonic marginal fm unchanged; pectorals enlarged; notochord turning upward ver}^ slightly. The linear chromatophores on underside of yolk sac now more numerous, giving a ''pin feather" effect, and those on sides of sac increased greatly in size and remarkably stellate; others unchanged. Head less blunt than before; lower jaw slightly shorter. All specimens examined thus far with heavy dorsal pigment on head and beginning of dorsal ridge, then a break until shortly before vent during which chroma- tophores are quite sparsely distributed, thence closer together, more numerous, and forming a verv distinct 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 New York (State).
