Abstract
A study of the form and functioning of Aglaja cylindrica and Aglaja aureopunctata. In this family the radula and gizzard plates are absent. In Aglaja cylindrica the buccal bulb has enlarged to form a pump used to suck in polychaete and nemertine worms. In Aglaja aureopunctata the buccal bulb can partially evert, enabling the species to ingest shelled opisthobranchs. In both species an oesophageal crop fulfils the role of the reduced stomach. A short review of the histology of the digestive gland is also included.Keywords
