Thanks to all who gave the informative responses about Humfrey's book.
Anybody know if the paperback Shells of Hawaii by Kay and Schoenberg (1998)
is the same as Kay's 1979 hardcover?
Also, is Seashells of Eastern Arabia by Peter Dance (1998) basically the
same as
the one credited to Bosch, Dance, Moolenbeek, Oliver (1995)?
