A Type Catalog of Fossil Invertebrates (Mollusca: Bivalvia and Rostroconchia) in the Yale Peabody Museum Russell D. White Laura K. Skorina (Received 29 August 1999) Abstract Type material for 60 nominal species of fossil bivalves and rostroconchs is in the Invertebrate Paleontology Collections of Yale University’s Peabody Museum of Natural History. Primary types for 46 nominal species include 41 holotypes, and 5 syntypes (representing 3 nominal species). Secondary types for 15 nominal species include 31 paratypes. Tertiary types of 19 nominal species include 35 hypotypes. Most types are from Kansas, Michigan, New York State, Pennsylvania, South Dakota, and Peru, and have been described by G.A. Cooper, A.L. McAlester, E.T. Nelson, N.D. Newell, J. Pojeta, PE. Raymond, and I.G. Speden.

Introduction This catalog lists all known fossil bivalve and rostroconch types in the Invertebrate Paleontology Collections housed in Yale University’s Peabody Museum of Natural History. This is the fourteenth 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. Forty-five 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 indi- cated 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 Postilla 227 + 30 September 2003 © 2003 Peabody Museum of Natural History, Yale University 2 Postilla 227 used by the Division of Invertebrate Paleontology prefixed with the abbrevia- tion YPM and the type status of the original designation, followed by all known references to that specimen. Any subse- quent designations are listed under the original designation and are cross-refer- enced 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 and syntype for name bearers; paratype for secondary types; hypotype is used for all tertiary types. Name bearers and secondary types are defined as used in the Interna- tional Code of Zoological Nomenclature (ICZN 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 specimens used in an original species description but not explicitly designated primary or secondary types, or any referenced specimen that cannot be placed unequivocally in a known species (e.g., Leiopteria sp.). Locality descriptions follow each entry or set of entries with identical locality data. The locality information includes the stratigra- phy, geography, collector and date. Stratigra- phy has been standardized using Strati- graphic Nomenclature Databases for the United States, its Possessions and Territories (MacLachlan et al. 1992). Township and range coordinates (e.g., NW NE sec 11 T21N R24E) are used to described the geographic position of some localities (Van Zandt 1976).
