Four decades after its publication, Rolf A.M. Brandt’s 1974 monograph on the non-marine molluscs of Thailand remains the main authority on freshwater and estuarine species for Southeast Asia and includes up to 165 new species of snails and bivalves described by Brandt and colleagues in the same book and preceding publications. All the holotypes are lodged at the Forschungsinstitut und Naturmuseum Senckenberg in Germany, and are largely inaccessible to Thai and other Southeast Asian researchers, who rely heavily on the Brandt collection as a key reference. Paratypes were, however, donated to various other collections, including some in Thailand. We present the first catalogue of 45 paratypes of gastropods of the Brandt collection, described from Thailand, Laos and Cambodia, which are lodged at the Faculty of Tropical Medicine, Mahidol University, Thailand.

罗夫·AM·勃兰特（Rolf AM Brandt）1974年出版的关于泰国非海洋软体动物的专着仍然是东南亚淡水和河口物种研究的主要权威，并且包括多达165种由布兰特及其同事描述的蜗牛和双壳类新物种。书和先前的出版物。所有的整型都存放在德国的Forschungsinstitut und Naturmuseum Senckenberg，泰国和其他东南亚研究人员基本上无法获得，他们严重依赖Brandt收集作为主要参考。然而，将同名型捐赠给其他各种收藏，包括泰国的一些收藏。我们提供了泰国，老挝和柬埔寨描述的布兰特（Brandt）集合中的腹足动物的45种亚型的第一个目录，它们存放在Mahidol大学热带医学系，
