David the types of most of the species you refer to are available and
working on the excellent illustrations in Sowerby, Reeve, Roemer and others
it is difficult to find any characters separating velata (not veluta as you
spelt the name) Sowerby,1833 (Proc Zoo Soc.,1833) and lima Reeve,1844 (Proc
Zool Soc. 1844) from the illustration and description of foliata Forrskal,
1775 (Moerch p.40, 502), this species could also have an even earlier name,
Arca ovata Gmelin, 1791) according to Richardson, Abbott and Davis [in]
Tryonia 1.August 1979.
A. decussata Sowerby, 1833 is a name preoccupied by decussata Linnaeus, 1758
and appears to be a synonym of B. grayana (Dunker, 1858). Type photographs
of A. lima Reeve, B. velata Sowerby and B. decussata Sowerby are figured on
pages 47 of my recent book "Bivalves of Australia Volume 2".

Subject: Barbatia help needed
> 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.
