Antiseizure Medication InteractionsUnionoid bivalves have a long history of classification and reclassification. Pre-Darwin classifications were deductive and artificial, reflecting character selection and weighting. More recent classifications, which should be natural and inductive to reflect phylogeny, reveal a diversity of methodologies and results.

A problem for the people dealing with this group is its systematic classification (Chaps. 3, 4, 14, this Vol.). This problem is due to the low number of adult characters which may be used for systematics (Chaps. 4, 14, 15, this Vol.). Though there ar

Two other species (one genus) from New Guinea are placed tentatively in the Unionidae.
