Tritonium is a genus of sea snails, marine gastropod mollusks in the family Cancellariidae, commonly known as the nutmeg snails.
Confusion increased when, during the 18th and 19th century, authors added species but didn't specify to which Tritonium they belonged.
The authors of the World Register of Marine Species (WoRMS) have arbitrarily attributed the species now placed in Buccinidae, Muricidae, and other neogastropod families, to Tritonium O.F.
The species now placed in Ranellidae and Bursidae, have been attributed to Tritonium Röding, 1798.
