Lymnaea columella (Say, 1817)

We found one specimen of L. columella in an artificial pond for keeping ornamental fish and water lilies. This site was on Water Island in a private garden, and the pond was not connected to any natural drainages. This species has been reported as widespread in Puerto Rico ( van der Schalie 1948; Ferguson and Richards 1963; Harry and Hubendick 1964), but not between Puerto Rico and Venezuela ( Harry and Hubendick 1964). This is the first record from the Virgin Islands.

Physidae

Two genera are known from the Caribbean: Physa and Stenophysa ; S. marmorata (Guilding 1828) has been reported from St. John ( Smith and Brousseau 1996). We did not encounter Stenophysa in our surveys.
