Marilyn Anness helped with the photography and analysis of a portion of this work, which is greatly appreciated. For one of us (D.G.A.) the initial interest in the nematode was sparked by S. Ward in whose laboratory the first half of the reconstruction was done. Discussions with John White on both anatomy and function have contributed to the interpretation of how the pharyngeal nervous system works. Sydney Brenner, kindly provided laboratory space and encouragement. Part of the work was supported by NSF grant no. GB 36970 to S. Ward. The completion of the work was done during the tenure of a Research Fellowship of Muscular Dystrophy Associations of America to D.G.A.

Recently, pale yellow fluorescence seen cytologically by the formaldehyde induced fluorescence technique of Fuxe & Jonsson (1973) has been found localized over the position of the NSM cells in the pharynx (J. Sulston, personal communication). This pale fluorescence which can be distinguished from the dopamine fluorescence seen in the nematode (Sulston, Dew & Brenner 1975) suggests that the NSM cells might contain serotonin.
