Land snails belong to the Phylum Mollusca, Class Gastropoda and include two groups
prosobranchs and pulmonates. Prosobranchs, frequently have heavily calcified shells and opercula
covering the aperture or opening or their shells. Pulmonates, lack opercula. As herbivores, snails eat
many kinds of fresh and dead leaves and are eaten by many animals such as some predacious
insects, snakes, birds and small mammals. They live under leaves, litter, logs, stones and trash. They
carry serve as hosts for some parasites such as Hemiplecta distincta can be comsumed by people in
northeastern Thailand and intermediate host also would be an intermediate host of a rat lung worm
Angiostrongylus cantonensis causing human meningitis (Panha,1987; 1988). However earlier land
snails non-marine mollusks of Thailand have attracted the attention of comparatively few specialists.
Species list of land snail were reported for Chonburi Province previously by Panha (1996), Hemmen
and Hemmen (2001) and Panha and Burch (2005). The present study was undertaken to update the
