Revised catalogue of the type specimens of recent fishes in the Institute of Taxonomic Zoology (Zoölogisch Museum), University of Amsterdam, The Netherlands

This is a revision of the catalogue issued in 1982 (Nijssen et al.) of type specimens of Recent fishes in the collections of the Zoölogisch Museum Amsterdam (ZMA), also named Institute of Taxonomic Zoology of the University of Amsterdam. These include 203 holotypes, 3 neotypes, 56 lectotypes, 1839 syntypes, 5965 paratypes, and 1010 paralectotypes of 884 nominal species or subspecies. Of syntype series, only the specimens still present in the ZMA collection are recorded. In many cases, specimens of such series have been sent on exchange among others to Vienna (1915), Leiden (1917 and following), Manilla, New York (1927) and London. Whether or not all of these specimens are really syntypes is not clear, due to incomplete curatorial administration during the time of M. [C. W.] Weber (curator of ZMA from 1883- 1922) and L. F. de Beaufort (curator from 1922- 1949). In Weber & de Beaufort’s “The fishes of the Indo-Australian Archipelago” and in many other publications, new species were often described without statement of the actual number of specimens involved. Records in the literature of certain syntypes as “holotype” are incorrect. For example, Menon’s (1977: 88-89) “holotype” of Cynoglossus heterolepis is still one of the 20-odd syntypes, most of which were not examined by Menon.
