The initial allusion to Chesapecten jeffersonius obviously brings
to mind C. madisonius.  Placopecten clintonius would refer to DeWitt
Clinton, a prominent U.S. politician of the early 1800's.
        As to anagrams, Advena Palmer, 1937 (an Eocene sepiid) turned out
to be preoccupied, so she rearranged the letters to form the genus Anevda.
However, it was synonymized with Belemnosella.  I believe there is a fossil
bivalve with anteroposteriorly reversed dention where the author of the
genus simply reversed the name of a related genus with normal dentition.
        Caecum findum was considered but not used for a Pliocene species.
