Phil.
The specimens I have labelled are very similar. P.alexandri is a little
larger and broader (approachng 50%)whereas P.souvillei is narrower  and a
little smaller. Also these P.souvillei mostly have a lighter coloured
periostracum than alexandri. Cant find the reference I used to ID these but
will look around.
