Abstract
Investigations of the pattern of neurosecretion in the prosobranch snail Cleopatra bulimoides were carried out. The nervous system consists of four paired and three unpaired ganglia. They are connected to each other by commissures and connectives. Although neurosecretory cells are present in all the ganglia examined, they are lacking in both connectives and commissures. The neurosecretory cells are classified into three types; two of them (A and B) are distributed all over the nervous system, while the third type (C) is localized only within the cerebral ganglia. Cleopatra bulimoides acts as an intermediate host for the digenetic trematode Gastrodiscus aegypticus, a parasite of cattle.
