A first complete list of the reptile type specimens preserved in the Museo Nacional de Ciencias Naturales (CSIC) of Madrid (updated until 15 July 2012) is provided. The collection houses a total of 318 type specimens representing 24 taxa belonging to 6 families and 12 genera. There are 22 taxa represented by primary types (19 holotypes, 2 neotypes and 1 lectotype) and at least one paratype, and only two taxa are exclusively represented by one secondary type (paratype). The collection is specially rich in Spanish endemisms. Special attention is deserved by the type series of many subspecies of Podarcis lilfordi described by A. Salvador and V. Pérez-Mellado. All type specimens are housed in the Herpetological collection except Blanus mariae and Psammodromus occidentalis type series and Psammodromus hispanicus (neotype) which are preserved in the DNA/Tissues Collection.
