Material collected during malacological surveys in Pakistan in 1990-1992 is discussed. Previously, only one slug species, Anadenus altivagus Theobald, 1862, was recorded from Pakistan. Deroceras laeve (O. F. Müller, 1774) and Candaharia rutellum (Hutton, 1849) are documented for the first time from the country. Distribution maps and ecological notes are provided for the Pakistan records of these three slug species.

We also report exact localities of Dicharax ataranensis (Godwin-Austen, 1914), Dicharax notus (Godwin-Austen, 1914), and Dicharax omissus (Godwin-Austen, 1914). The new records extend the known distribution of Chamalycaeus and Metalycaeus in Thailand.

The genera Aulacospira and Pseudostreptaxis of the Philippines are revised based on the collections of the Senckenberg Forschungsinstitut und Naturmuseum (Frankfurt am Main, Germany), the Florida Museum of Natural History (USA), and recently collected material. Three new species are described: Aulacospiralens Páll-Gergely & Auffenberg, sp. n., Aulacospirakrobyloides Páll-Gergely & Schilthuizen, sp. n., Pseudostreptaxisharli Páll-Gergely & Schilthuizen, sp. n.
