Contour of digital plate slightly rounded or angular. Three opaque bars, representing the toes, are visible, with the more translucent intermediate tissue constituting the "; Tip of third toe not yet pointed. 2. Visceral arches: Maxillary process fused with wall of nasal groove (notch visible at point of fusion ). The diMal tip of the second arch, known as the "collar," completely overlaps visceral arches 111 and IV. The third and fourth visceral clefts are no longer visible. 3. Beak: Faintlv recognizable in 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. ).
