> Trying to track down authors and dates, I ran into a couple of problems
with Barbatia lima (Reeve, 1844).  First, different references synonymized
it with foliata Forsskal 1775, veluta Sowerby 1833, decussata Sowerby 1833,
and various junior synonyms, but did not agree in detail.  One synonymized
lima under foliata and veluta, not decussata; one had it under decussata and
veluta but not foliata, and one had it under decussata but not veluta.
Secondly, one reference claimed that decussata was a junior homonym of
decussata Linnaeus.  However, Byssoarca decussata Sowerby, 1833 is not a
primary homonym of Arca decussata Linnaeus, 1758.
