Notes on terrestrial molluscs of Java, Bali and Nusa Penida

This paper includes the descriptions of twelve new species from Java, Bali, and Nusa Penida, belonging to the families Assimineidae, Cyclophoridae, Diplommatinidae, Achatinellidae, Ariophantidae, Camaenidae, Endodontidae, and Euconulidae. Previously included in the Valloniidae, the genus Anaglyphula Rensch, 1932, is transferred to the Assimineidae. Javanese and Balinese shells generally identified as Lamprocystus infans (Pfeiffer, 1854) are found to differ from the Bornean shells of this species, including the type. Diagnostic characters are given to facilitate the identification of shells of some Macrochlamys and Helicarion species which are often confused.
