The shells shown on the following web page were included within a group of
variously identified pulmonate species, in the Archerd Shell Collection.
Most of these land snail shells had been collected in Caribbean and Western
North American locations, c.1950-1960. We have no other information on this
particular shell.

We would appreciate suggestions from persons familiar with land snail
families.
