Abstract
Abstract 1. The central nervous system of the mollusc Philine aperta (Gastropoda; Cephalaspidea) was studied using the alcian blue/alcian yellow/phloxin histochemical technique to identify putative peptidergic neurons. 2. The position, size and staining colour of positively stained somata were mapped by reconstruction from serial sections of the major ganglia. 3. Positively stained neurons were found in all of the ganglia studied. Based on staining colour, three cell types were identified in the cerebral ganglia, four in the pedal and supraoesophageal, two in each of the pleural, suboesophageal and visceral ganglia and one in the genital ganglion. 4. Some comparisons can be made between the results of this study and other maps of peptidergic neurons derived from alcian blue/alcian yellow histochemical studies of gastropod nervous systems.
