Introduction. By Richard. S.. Boardman. The Paleozoic cephalopod catalog listing invertebrate fossil type. the first in a proposed series. is. of the Division of Invertebrate. specimens. Paleontology of the Smithsonian Institution. The only other published catalog (Schuchert, 1905, USNM Bulletin 53, pt. 1) covered the entire type collection of fossil invertebrates held at that time. Since 1905 the. type collections have grown from approximately 11,500 to nearly 200,000 (fig.. In. 1).. compiling the cephalopod catalog. pared with published pictures, and. This. is. all. illustrated types were com-. all of the. nomenclature was rechecked.. necessarily a long and detailed task accomplished with meticu-. lous attention by. Museum. Specialist Louis R. Purnell, under the super-. vision of Erie G. Kauffman, Frederick J. Collier, and myself. All of the. Paleozoic cephalopod type specimens acquired through 1965 are listed.. The Collection Specimens. in the. type collections include the primary types and sec-. ondary types designated. in the literature.. Designation can be by. illus-. measurement of other mention. Each individually mentioned type specimen receives a separate catalog number. Primary or secondary types which have not received individual designation are collected into occurrence suites and each suite is given a catalog number. Kinds of primary types differentiated in the collection stration, or isolation in the text by. include holotypes, syntypes, lectotypes, paratypes, paralectotypes, and. neotypes, as defined in articles 73-75 of the International Code of Zoological Nomenclature. Secondary types identified to species are generally. termed hypotypes. for. purposes.. curatorial. Secondary. types not. identified to species or identified with a degree of doubt are termed. simply figured or mentioned specimens.. placed. in the. urement are based on the plastotype cluded. in the. Plastotypes are cataloged and. type collections when illustrations, descriptions, or measitself.. Other plastotypes are. in-. type collection at the discretion of the curator.. In addition to the type collection listed in this catalog, the division. Curator-in-Charge, Division of Invertebrate Paleontology..

U.S.. NATIONAL MUSEUM BULLETIN. 262. maintains a large nontype collection of identified specimens arranged taxonomically, in cooperation with the Paleontology and Stratigraphy. Branch of the U.S. Geological Survey. Unstudied specimens are generally filed by occurrence data in a third collection.. The Catalog The cephalopod catalog is divided into four major chapters: Nautiloidea, Ammonoidea, Bactritoidea, and Coleoidea. Within each chapter the taxa are listed alphabetically by genus and species. With one exception, a. specimen. is. entered only once and under the first generic and species. combination assigned, regardless of the number of times or reillustrated. is. The exception. it. is. redescribed. previously described specimen that. is a. redescribed as a primary type of a new species, whether or not the. generic designation is also changed.. The catalog is meant to be an objective and brief listing of type specimens and not a source book for occurrence data, synonymies, or stratigraphic interpretation of any kind. Individual citations include the binomen, author, date, page, plate, figure numbers, kind of type, catalog number, rock unit as originally designated, and state, province, or country,. whichever best applies. A. full. bibliography. located at the end of. is. the catalog.. Use. of the Collections.
