Since the publication of my monograph of the Indo-Australian Clausiliidae (Loosjes, 1953) I obtained some additional information, consisting mainly of new distribution records and data on shell-structures. The present paper deals with these additional data, while furthermore two new species are described. The specimens concerned were obtained on loan from the following Museums: Zoölogisch Museum, Amsterdam (Z.M.A.), Rijks Museum van Natuurlijke Historie, Leiden (R.M.N.H.), Museo Civico di Storia Naturale di Genova (M.C.G.), Natur-Museum Senckenberg, Frankfurt am Main (S.M.F.), Ueberseemuseum, Bremen (U.M.B.).
