Summary
An investigation of the neurosecretory cells of three intertidal species of nemerteans,Procephalothrix spiralis (Coe, 1930) (Palaeonemertini),Lineus socialis (Leidy, 1855) (Heteronemertini) andAmphiporus lactifloreus (Johnston, 1828) (Hoplonemertini) was performed. Cell types are described and their distribution and relative abundance in the central nervous system reported. Neurosecretory cells were examined for diel activity and a relationship with sexual state. A change in the cytology of the neurosecretory cells was only noted with respect to the sexual state of the animal.
