This paper meets the requiremerits of ANSI/NISO Z39.48-1992 (Permanence of Paper). Peabody Museum of Natural History Yale University New Haven, CT 06520-8118 (Received 9 June 1998) Abstract Type material for 373 nominal species of fossil gastropods is in the Invertebrate Paleontology Collections of Yale University’s Peabody Museum of Natural History. Primary types for 193 nominal species include 164 holotypes, 191 syntypes (representing 29 nominal species) and 4 lectotypes. Secondary types for 79 nominal species include 228 paratypes (representing 75 nominal species) and 9 paralectotypes (representing 4 nominal species). Tertiary types of 172 nominal species include 1034 hypotypes. Most types are from St. Louis (Missouri), Chazy (New York), Zorritos (Peru) and Syria and have been described by T.D.A. Conrad, J. B. Knight, E.T. Nelson and P.E. Raymond. Key Words Type Catalog, Gastropoda, Yale Peabody Museum, St. Louis, Chazy, Peru, Syria, T.D.A. Conrad, J.B. Knight, E.T. Nelson, P.E. Raymond.

McFadden and Laura K. Skorina Introduction This catalog lists all known fossil gastropod types in the Invertebrate Paleontology Collections housed in Yale University’s Peabody Museum of Natural History. This is the ninth in a series of type catalogs of fossil invertebrates and is a product of an ongoing computerization project to improve the accessibility of the type collections. Eight type specimens are missing and cannot be located. The collections have been thoroughly searched by the curatorial staff in the 1960s and 1990s and it is believed that these specimens are perma- nently lost. Missing specimens are indicated with a footnote, and any information on their whereabouts would be greatly appreciated. Organization Specimens are listed under the originally described binomen; genera and species within genera are indexed alphabetically. Each entry includes the catalog number used by the Division of Invertebrate Paleontology prefixed with the abbreviation YPM and the type status of the original designation, followed by all known refer- ences to that specimen. Any subsequent designations are listed under the original designation and are cross-referenced in the body of the text. Locality descriptions follow each entry or set of entries for each binomen. Errors and inconsistencies are footnoted at the bottom of each binomen. The type designations used are holotype, syntype and lectotype for name bearers; paratype and paralectotype for secondary 2 Type Catalog of Fossil Gastropoda Postilla 218 types; hypotype is used for all tertiary types. Name bearers and secondary types are defined as used in the International Code of Zoological Nomenclature (I\CZN 1985). Tertiary types or hypotypes are treated here as any described, figured or measured specimen used in a publication to augment the knowledge of a previously defined species, any specimen used in an original species description but not explicitly designated a primary or secondary type, or any referenced specimen that cannot be placed unequivocally in a known species (e.g., Hormotoma? sp. A). Locality descriptions follow each entry or set of entries with identical locality data. The locality information includes the stratigra- phy, geography, collector and date. Stratigraphy has been standardized using Stratigraphic Nomenclature Databases for the United States, its Possessions and Territories (MacLachlan et al., 1992).
