title: Neurosecretory cells in the central nervous system of Helicella virgata (Gastropoda, Pulmonata).
abstract: The central nervous system of Helicella virgata was first investigated with chrome-haematoxylin phloxin and paraldehyde-fuchsin techniques for the detection of neurosecretory cells. With the alcian blue/alcian yellow staining method five cell types were identified within the class of Gomori-positive cells. It was further established that the group of Gomori-negative cells distributed in the right parietal and left parieto-visceral ganglia reacts positively with alcian blue/alcian yellow method. These cells are to be included in the Yellow Green Cells type.
