A first skeleton draft of this type list was prepared by Dr. L.W. van den Hoek Ostende (RMNH) under the supervision of Dr. M.S. Hoogmoed in the period 1995/96, during work on the Delta Plan for the Preservation of Cultural Heritage, a project financed by the then Ministerie van Welzijn, Volksgezondheid en Cultuur (= Ministry of Welfare, Public Health and Culture). This project provided Dutch National Museums, among which the RMNH, ‘with extra funding above their normal operating budgets to reduce arrears in conservation and registration. It provided a unique possibility to register type-material and thus fulfil recommendation 72G (4) of the International Code of Zoological Nomenclature, viz., that ‘every institution in which name-bearing types are deposited should publish lists of name-bearing types in its possession or custody’. The registration of types and specimens of extinct or endangered species in the vertebrate collections [was] one of the many projects in the National Museum of Natural History financed by the ‘Delta Plan’’(Hoek Ostende et al., 1997). Prof. Dr. U. Fritz provided useful suggestions about the status of old material of some European and Southeast Asian species of Mauremys and Cyclemys. R. de Ruiter, collection manager of the herpetological collection of the National Museum of Natural History, Leiden, The Netherlands, provided information about recent herpetological material in the RMNH collection.
We want to thank Dr J. de Vos and R. van Zelst of the department of Geology of the National Museum of Natural History for the help and the information they provided about the fossil Dubois type material in the RMNH collection.
The present work has been partly financed by a grant from the SenterNovem Type Project (project no. 1280).
