Hi Marcus and Conchlers,
I was thinking recently about this question, as I have to decide
whether to use the classical regions (or 'provinces') in a forthcoming
book. Some of them, such as the Magellanic and Panamic provinces, seem
to reflect a distinct fauna that has boundaries, however vague, that
allow a fuzzy line to be drawn, but the integrity of some others, such
as the Indo-Pacific or Japonic, does not survive testing. The more we
learn about each species, the more we see how factors such as surface
currents and water temperatures can shape their distribution more
strongly than just their geographical locations.
Province names can thus be a useful shorthand in some cases, but their
use in publications should always be accompanied by a map showing where
that particular author sees each one beginning and ending.
I don't think I'll be using them.
Regards,
PC.

I remember some time ago a discussion was placed here about World
geographic regions for shell
distribution (Caribbean, Patagonian, etc.).
Is there a recent list available somewhere?
thanks
Marcus
