NOTES ON THE FAMILY AMPULLARIIDAE (GASTROPODA: PROSOBRANCHIA) IN THE PHILIPPINES: I. DIGESTIVE, CIRCULATORY, AND EXCRETORY SYSTEMS
Abstract
A total of 232 ampullariid snails collected from 23 sites covering 7 islands in the Philippines were
compared conchologically and 200 alcohol-preserved specimens were dissected for anatomical
characteristics. Conchological comparison of the shells of the collected snails with that of identified lots from the
Senckenberg Natur-museum, Frankfurt, Germany, the British Museum for Natural History, London, England,
the Koninklijk Belgisch Instituut voor Natuurwetenschappen, Brussels, Belgium, and the Rijksmuseum voor
Natuurwetenschappen, Leiden, Netherlands, revealed the presence of 5 species in the collected samples. These
are: P. conica, P. ampullacea, P. mainitensis, P. quadrasi, and P. vittala. The latter 3 species were previously
reported as being indigenous to the Philippines.
Aside from characteristics of the shell, the morphology of the stomach may be useful for species
discrimination. P. quadrasi and P. vittata, however, do not seem to differ anatomically from P. conica.
