Semithin plastic sections of stages L3 and L4 larvae stained with hematoxylin, eosin. and alcian blue, (a) Early stage L3 larva in sagittal section; ventral is to the left and anterior toward the top of the page, unless noted. Arrow points to algal particle entering stomodeum. Roman numerals denote locations of three trunk coelomic spaces, (b) Higher magnification view of same stage larva as in (a), (c) Oblique frontal section of a late stage L3 larva. Arrow points to an anterior septum dividing one of the region A segments, (d) Oblique transverse section through head of stage L4 larva with dorsal side up. (e) Frontal section through palette rudiments (segments B2-B5). (f) High-magnification view of transverse section through ventral body wall of stage L4 larva midway between the mouth and anterior mesotroch. Arrowhead points to the ventral nerve cord. Arrow indicates the ventral mesentery, (g) Transverse section, with ante- rior to the left, through posterior metatroch (setiger B2) and palette rudi- ments (setigers B3-B5). Arrowhead points to trochal cell. Ih. i) Sections through trochal bands at stage L4 tangential to body wall. Arrow points to line of basolateral trochal cell nuclei, ce, circumesophogeal connective; eg, neuropil of cerebral ganglion; e, endodermal cell of the midgut; he, head coelom; mg. midgut: ml, mesotroch; pal. pallette rudiment; pv, pharyngeal valve; se, stomodeum: vbv. ventral blood vessel; vnc, neuropil of ventral nerve 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. ).
