Nervous system and reproductive system in a neomenioid, Strophomenia scandens (A, D) and nervous system in a chaetoderm, Limifossor lalpoideus (B, C). (A) Lateral (= pleural, visceral) cord with its ongm in the cerebral ganglion separate from the origin of the ventral (= pedal) cord. Lateral and ventral cords remain separate posteriorly (after Heath, 1904, pi. 27, fig. 2). (B) Anterior end; the lateral and ventral cord have a single origin in the cerebral ganglion (after Heath, 1911, pi. 10, fig. 8). (C) Posterior end: the ventral cord runs close to the lateral cord and fuses with it. The suprarectal commissure is ganglionated (after Heath, 1905. pi. 43, fig. 18). (D) Posterior end; the lateral and ventral cords are well separated, with the separation maintained throughout. The gonad empties into the pericardium, which is shown in fine stippling. The U-shaped gametoduct, with a many-lobed seminal receptacle, is shown in coarse stippling; it runs from the posterior end of the pericardium to the mantle cavity, indicated by dashed lines (after Heath, 1904, pi. 27, fig. 6). 1 cerebral ganglion, 2 lateral cord, 3 pedal cord, 4 suprarectal ganglion/commissure, 5 buccal ganglion, 6 gonad, 7 pericardium, 8 seminal receptacle, 9 mantle 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. ).
