Abstract
A simple checklist of the opisthobranch molluscs recorded from Fiji is presented and contains 253 species. Only six of the nine opisthobranch orders are included — Cephalaspidea (43 species), Entomotaeniata (6), Anaspidea (6), Notaspidea (7), Sacoglossa (29) and Nudibranchia (162). A brief comparison of these groups with northeastern Australia highlights two main points: the potential for new records from Fiji and the large number of still unidentified species already found .
