Shalom Chris
do you mean an article in # 33(1), 2005? I am personally acquainted with the
author.

People sometimes forget that subspecies, talking about living molluscs, are
geographically separated populations, which differ from other populations of
the same species by statistical shell characteristics. So if one finds an
unusually large shell of  C. tigris in Kenya this shell, in my opinion,
should be treated as a huge tigris shell and not as C. tigris schilderiana.
One can find in the literature curious things when geographical separation
is not considered: Cyp. pantherina catulus or hybrid pantherina  x tigris
from Hurghada, northern Red Sea (the former is a subspecies described from
the Gulf of Aden, the only area where tigris and pantherina may meet). There
are many other examples.
Sometimes a term 'form' is used instead of a term 'subspecies'.  Is this
correct?
Sincerely
Ed
