HOWE I SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY ? NUMBER 517 SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Folklife Studies Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review. Press requirements for manuscript and art preparation are outlined on the inside back cover. Robert McC.

Vari and Jeffrey C. Howe Introduction The collections of type specimens in the Division of Fishes, National Museum of Natural History, Smithsonian Institution, are among the largest in the world, including specimens from the freshwaters of all continents and from marine waters throughout the planet. At the end of 1990 there were approximately 15,500 putative type lots of Recent fishes in these collections. The large number of lots in the type collections, and the diversity of taxa they represent from all regions of the world, makes it unrealistic to attempt to produce a comprehensive listing of all type specimens in the collections within the foreseeable future. Rather than wait some decades until an all-inclusive listing could be prepared, it was decided that listings of type specimens for subunits of the collection should be prepared by specialists in each group. This listing is the first of these efforts prepared in response to Recommenda- tion 72G(4) of the International Code of Zoological Nomencla- ture (ICZN) that "Every institution in which name-bearing types are deposited should publish lists of name-bearing types in its possession or custody." We have chosen to address the fishes of the order Characiformes as our first effort because these are the focus of ongoing research projects by the senior author. Members of the order are also major components of the freshwater ichthyofau- nas of Africa and particularly South and Central America. These regions are the focus of increased research by systema- tists, ecologists, and other scientists attempting to assess and Richard P. Vari and Jeffrey C.

Mead, Smithsonian Institution. Review- ers for this paper: Karsten E. Hartel andHoracio Higuchi, Museum of Comparative Zoology, Harvard University. describe the biological diversity on those continents where aquatic ecosystems are progressively adversely impacted by myriad development schemes and human population pressures. The type specimens of characiform fishes in the collections of the Division of Fishes came from two primary sources, (1) the field work and systematic studies of curators and other researchers associated with the division, and (2) exchanges from colleagues and institutions worldwide. Type specimens originally deposited in the division and reported on during this century are nearly invariably cited with USNM catalog numbers. Citations of catalog numbers were often lacking for species described in the nineteenth century. Many types were exchanged to the Smithsonian subsequent to publication under a catalog number of another institution. Foremost among these are a number of paratypes of species described by Carl H. Eigenmann and his co-workers that were exchanged to the Smithsonian from the Carnegie Museum, Indiana University, and Museum of Comparative Zoology. Syntypes of various species of African characiforms were also received in exchange from the British Museum (Natural History) (now the Natural History Museum, London) and the Museum National d'His- toire Naturelle, Paris. This listing will serve to bring those specimens and others to the attention of interested researchers. MISSING TYPE SPECIMENS OF SPECIES DESCRIBED BY GILL.?Gill (1858, 1871) described a series of characiforms with type localities on the island of Trinidad and in the western portions of the Amazon basin. In neither paper did Gill, however, cite the depository of the type specimens, nor did he, in most cases, state the number of specimens on which he based his descriptions. Type series of four species described in Gill's 1858 paper (Curimatus argenteus, Erythrinus cinereus, Macro- don ferox, and Poecilurichthys Brevortii) are deposited in the SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY collections of the Division of Fishes (see following listing for details). The type series of the other seven characiform species described in that paper (Corynopoma Riisei, C. Veedonii, Nematopoma Searlesii, Poecilurichthys pulcher, P. taeniurus, P. (Hemigrammus) unilineatus, and Stevardia cdbipinrds) were not located in the collections of the Division of Fishes, nor was any indication found in the USNM ledgers that they had been deposited at the Smithsonian. Gill described five species of characiforms from the western portions of the Amazon basin in 1871, again without any indication of where the material was deposited. The type series of four of these (Astyanax Carolinae, Hydrolycus Copei, Pygocentrus alatus, and Raeboides Myersii) were located in the holdings of the Division of Fishes, but no trace was found of the type specimens of the fifth species (Tetragonopterus Ortonii). ABBREVIATIONS.?Most of the specimens listed in this catalog were described under USNM catalog numbers. A number of the cited type specimens were, however, deposited in other institutions at the time the species was described. In addition, in some instances specimens originally reported on with USNM catalog numbers have been exchanged to other repositories. These various changes are noted under "Remarks" for each species with the following abbreviations for institu- tions and collections used in those citations.

ZMA Institute voor Taxonomishes Zodlogie, Zoologish Museum, Amster- dam Some authors have incorrectly cited the name of the museum encompassing the Division of Fishes as "United States National Museum of Natural History" rather than its official name "National Museum of Natural History." These actions presumably are an attempt to reflect the acronym used for the collection, USNM, in the supposed title for the museum. The acronym USNM for the collections of the present National Museum of Natural History is derived from the name for the organization originally housing both those collections and others, the United States National Museum. The collections encompassed within the former United States National Mu- seum incorporated natural history specimens, fine art objects, and historical items. The later two classes of objects were moved to other Smithsonian museums and the original museum was renamed the "National Museum of Natural History" (NMNH) to better reflect its predominant research focus. The acronym USNM is still applied to the various holdings now housed in NMNH, although no longer reflecting the official name of the organization. ACKNOWLEDGMENTS.?This publication builds on an earlier effort by the staff of the Division of Fishes to develop a computerized listing of the putative types and associated USNM catalog numbers. The listing that resulted was completed in 1983 and was the first attempt to search the ledgers in the Division of Fishes for all listings of type specimens and to cross-check those records with the specimens curated in the type collection. Only 30 copies of the listing (without authorship) were produced and were distributed to the ichthyology departments of selected museums worldwide. Support in that project and in subsequent refinements of the type inventory was provided by Edgar "Nat" Gramblin, the late Robert Kanazawa, Victor G. Springer, Janet R. Gomon, Susan L. Jewett, Jeffrey T. Williams, Andrew Gerberich, Thomas Orrell, Jeffrey Clayton, Ann W. Vari, and many other past and present members of the Division of Fishes who have searched for and counted specimens, pored through over 200,000 ledger entries, and in many other ways provided the foundation both for this paper and future type specimen lists. M. Eric Anderson and David Catania (CAS) provided information on various characiform type series originally at Indiana University that are now deposited, at least in part, at NMNH. Karsten E. Hartel and Horacio Higuchi (MCZ) helped us to resolve numerous questions concerning type specimens received from MCZ. Darrell Siebert and Gordon J. Howes (BMNH) assisted with information on those lots received in exchange from the BMNH. Volker Mahnert (MNHG) provided information on type specimens in that collection. William L. Fink (UMMZ) and Paulo A. Buckup (UMMZ) sent us information on a variety of type series that they had on loan. The examination of various type specimens in Brazilian and Venezuelan institutions was made possible by funding from the Neotropical Lowland Research Program of the International Environmental Sciences Program of the Smithsonian Institution. Stanley H. Weitzman (NMNH), Bruce B. Collette (National Marine Fisheries Service, Systematics Laboratory), Victor G. Springer (NMNH), Marilyn Weitzman (NMNH), Karsten E. Hartel (MCZ) and Horacio Higuchi (MCZ) offered suggestions for the improve- ment of this paper. NUMBER 517 Format The following template has been used to structure each entry in the "Catalog of Types." Genus species (subspecies) Author(s), yearrpage, figure(s), plate(s). Type status USNM catalog number (number of specimens, range of standard lengths in mm). Locality (country, depart- ment, province or state, specific locality), collectors), date(s) collected. Remarks: Includes comments on originally cited author- ship and year of publication; reference to lectotype, or paralectotype designation; previous depository and catalog number of specimens; and correction and/or expansion of data on locality or collector. FAMILY (familial assignment following classification in Greenwood et al. (1966) as modified by Roberts (1974), Howes (1976), and Vari (1979)). This listing includes all known published characiform types deposited in the collections of the National Museum of Natural History through 1991. The order of listing is alphabetical by genus and then species and subspecies. Genus, species, and subspecies are spelled as they appear in the original description, except that diacritical marks have been deleted as recom- mended by the International Commission on Zoological Nomenclature. In instances where the original description included an incorrect spelling there is a cross-reference to a corrected entry elsewhere in the text Page refers to the first page of the species description. Complete references to publications can be found in Literature Cited. The presented "Type status" is that which is currently thought correct based on the original description and subse- quent literature designations. The categories for primary and secondary types used herein are holotype, syntype(s), lecto- type, paratype(s), and paralectotype(s) as defined by the International Commission on Zoological Nomenclature (1985), articles 73 and 74. Missing and exchanged types are indicated as such. A question mark following the type status indicates uncertainty concerning the specimen(s) in question, with the problem discussed further in the "Remarks" section under the species. Discrepancies between the number of specimens originally reported or listed in the USNM ledgers and those found when the lots were inventoried or at this time are noted and discussed under "Remarks." The cited length for the specimens is the present standard length in millimeters (mm). In those cases where a different measurement of length (e.g., total length) was presented in the original description, or where there is a discrepancy between the originally cited standard length(s) and present standard length(s), that is noted under "Remarks." Locality is presented as in the original description, with sequence of presentation of data standardized throughout. Modern equivalents for countries are provided in brackets where necessary. Collector and date collected are as in the original description. Modern and corrected localities for specimens collected during the Thayer Expedition to Brazil follow Higuchi (ms). Data on the specimens in addition to, or inconsistent with that in the original species description either located in the jar or in the ledgers in the Division of Fishes are discussed under "Remarks." Complete references for papers involving lectotype and paralectotype designations can be found in Literature Cited. The locality of additional type specimens for species are noted only in two circumstances. First, when the type specimens were originally cited with USNM catalog numbers and were subsequently exchanged to other institutions. Second, when type specimens were origi- nally cited under the catalog number of another institution and subsequently transferred to the Smithsonian. A large number of the type specimens cited in the following listing were described by Carl H. Eigenmann and his co-workers. Portions of the type series of these species were exchanged to the Smithsonian and other institutions from the Carnegie Museum and Indiana University, both prior and subsequent to the publication of the various species descrip- tions. In most instances, however, those exchanges were not noted in the ledgers of either the Indiana University or Carnegie Museum fish collections, making it difficult, or more usually impossible, to determine the disposition of the entire type series. All material cited as type specimens in the correspon- dence associated with such exchanges to the Smithsonian is included in the following listing except in those instances where collection information for the specimens now in the USNM collections does not agree with that given for the type series in the original species description. Correspondence concerning the type status of the specimens is archived in the files of the Office of the Registrar, National Museum of Natural History. Characiform classification has undergone major modifica- tions during the last quarter of a century and it is likely that it will be some time until the data is available to produce a stable familial nomenclature reflecting hypotheses of relationship based on shared derived characters. For that reason we have not arranged this list by family, but rather present it arranged alphabetically by original genus and species. Each taxon is assigned to a family following Greenwood et al. (1966) with several modifications. The Cynodontidae of those authors is considered a tribe within the Characidae, rather than a distinct family, in keeping with the results of Howes (1976). The Ichthyboridae of Greenwood et al. (1966) is placed within the Distichodontidae of those authors following Vari (1979). The genus Anodus Spix and its synonyms are placed in the family Hemiodontidae rather than Curimatidae in keeping with the findings of Roberts (1974) and Vari (1983, 1989a). Given the large number of outstanding problems involving the recogniz- able species of both the African and New World members of the Characiformes, it is premature to make comments on the validity or possible synonymy of most members of the order at this time.

Holotype USNM 1659 (1, MISSING). Colombia, Truando; Michler and Schott, 1857-1858. Remarks: USNM ledgers for other portions of collection indicate that collector is LL N. Michler; A. Schott cited as "preparator." According to introductory statements in Eigenmann and Ogle the material was collected "near the Rio Atrato." "Type" (= holotype) and 4 "Cotypes" (= paratypes) were intermingled in single lot (USNM 1659), which contained only 4 specimens when checked in 1982. Specimens remaining in lot were approximately 65,66,72, and 95 mm SL and evidently represent paratypes cited by Eigenmann as 68, 68, 75, and 100 mm to "base of caudal," a measurement that evidently included the 2 or 3 scales extending beyond hypural joint onto middle caudal fin-rays. The speci- mens remaining in the lot are estimated to have been 80, 83, 89, and +115 mm total length, not approximating the "105 mm. long over all" cited by Eigenmann for holotype. The holotype is apparently missing and the four specimens remaining in the lot are considered the paratypes; those were recataloged as USNM 306566. Paratypes USNM 306566 (4, 64.4-92.2 mm). Colombia, Tru- ando; Michler and Schott, 1857-1858. Remarks: Collected with holotype; see discussion under holotype with respect to these specimens; specimens originally cited as 68 to 100 mm to base of caudal.

LEBIASINIDAE Pyrrhulina maxima Eigenmann and Eigenmann, 1889c:lll. Possible Holotype USNM 120283 (3, 29.8-39.0 mm). Tabatinga; BourgeL Remarks: Eigenmann and Eigenmann based their spe- cies on "Type No. 6343; one specimen. .08 m. to base of caudal." The 3 specimens in USNM 120283 were originally part of MCZ 6343, which now consists of 11 specimens, 28.6-41.7 mm SL (M. Weitzman, pers. comm.). Thus none of the specimens known to have been part of MCZ 6343 approach the length cited by the Eigenmanns, even if we assume that their measurement represents total rather than standard length. It is impossible at this time to determine which of the NUMBER 517 37 specimens in USNM 120283 and MCZ 6343 may be the holotype.

Syntypes USNM 92970 (2, 30.6-32.7 mm). Rosario. Remarks: Received from G.S. Myers. According to letter from Myers accompanying accession (ace. no. 124667), these species are "Aquarium specimens bred from stock collected at Rosario, Argentina. The description was based on these two, male and female." LEBIASINIDAE Rachoviscus crassiceps Myers, 1926b: 1. Lectotype USNM 92971 (1, 32.7 mm). Collected for the aquarium trade and sent to Myers by A. Rackow of Germany. Supposedly collected in Brazil, neighborhood of Rio de Janeiro. Remarks: Designated as lectotype by Weitzman and Cruz (1981:1009). Weitzman and Cruz (1980:1008- 1009) suggest that the originally proposed type locality for the species is incorrect. Those authors note that the species is only known from near Guarituba, a small town -50 km S of Paranagua, state of Parana^ Those localities are a considerable distance to the south of Rio de Janeiro. At the time that the species was described, the German aquarium import trade was receiving fishes from that area of southern Brazil, and Weitzman and Cruz suggest that the fish may have been collected in the region of Paranagua and transhipped to Germany through Rio de Janeiro. Paralectotypes USNM 94216 (3, 17.2-30.7 mm). Remarks: No locality information, received from New York Aquarium Society.

Re- quests for special treatment?use of color, foldouts, case-bound covers, etc.?require, on the same form, the added approval of the sponsoring authority. Review of manuscripts and art by the Press for requirements of series format and style, completeness and clarity of copy, and arrangement of all material, as outlined below, will govern, within the judgment of the Press, acceptance or rejection of manuscripts and art. Copy must be prepared on typewriter or word processor, double-spaced, on one side of standard white bond paper (not erasable), with 1 VA" margins, submitted as ribbon copy (not carbon or xerox), in loose sheets (not stapled or bound), and accompanied by original art. Minimum acceptable length is 30 pages. Front matter (preceding the text) should include: title page with only title and author and no other information, abstract page with author, title, series, etc., following the established format; table of contents with indents reflecting the hierarchy of heads in the paper; also, foreword and/or preface, if appropriate. First page of text should carry the title and author at the top of the page; second page should have only the author's name and professional mailing address, to be used as an unnumbered footnote on the first page of printed text. Center heads of whatever level should be typed with initial caps of major words, with extra space above and below the head, but no other preparation (such as all caps or underline, except for the underline necessary for generic and specific epithets). Run-in paragraph heads should use period/dashes or colons as neces- sary. Tabulations within text (lists of data, often in parallel columns) can be typed on the text page where they occur, but they should not contain rules or numbered table captions. Formal tables (numbered, with captions, boxheads, stubs, rules) should be submitted as carefully typed, double-spaced copy separate from the text; they will be typeset unless otherwise requested. If camera-copy use is anticipated, do not draw rules on manuscript copy. Taxonomic keys in natural history papers should use the aligned-couplet form for zoology and may use the multi-level indent form for botany. If cross referencing is required between key and text, do not include page references within the key, but number the keyed-out taxa, using the same numbers with their corresponding heads in the text. Synonymy in zoology must use the short form (taxon, author, year: page), with full reference at the end of the paper under "Literature Cited." For botany, the long form (taxon, author, abbreviated journal or book title, volume, page, year, with no reference in "Literature Cited") is optional. Text-reference system (author, year:page used within the text, with full citation in "Literature Cited" at the end of the text) must be used in place of bibliographic footnotes in all Contributions Series and is strongly recommended in the Studies Series "(Jones. 1910:122)" or "...Jones (1910:122)." If bibliographic footnotes are required, use the short form (author, brief title, page) with the full citation in the bibliography. Footnotes, when few in number, whether annotative or biblio- graphic, should be typed on separate sheets and inserted imme- diately after the text pages on which the references occur. Exten- sive notes must be gathered together and placed at the end of the text in a notes section. Bibliography, depending upon use, is termed "Literature Cited," "References," or "Bibliography." Spell out titles of books, articles, journals, and monographic series. For book and article titles use sentence-style capitalization according to the rules of the lan- guage employed (exception: capitalize all major words in English). For journal and series titles, capitalize the initial word and all subsequent words except articles, conjunctions, and prepositions. Transliterate languages that use a non-Roman alphabet according to the Library of Congress system. Underline (for italics) titles of journals and series and titles of books that are not part of a series. Use the parentheses/colon system for volume (number): pagination: "10(2):5-9." For alignment and arrangement of ele- ments, follow the format of recent publications in the series for which the manuscript is intended. Guidelines for preparing bibli- ography may be secured from Series Section, SI Press. Legends for illustrations must be submitted at the end of the manuscript, with as many legends typed, double-spaced, to a page as convenient. Illustrations must be submitted as original art (not copies) accompanying, but separate from, the manuscript. Guidelines for preparing art may be secured from Series Section, SI Press. All types of illustrations (photographs, line drawings, maps, etc.) may be intermixed throughout the printed text. They should be termed Figures and should be numbered consecutively as they will appear in the monograph. If several illustrations are treated as components of a single composite figure, they should be desig- nated by lowercase italic letters on the illustration; also, in the legend and in text references the italic letters (underlined in copy) should be used: "Figure 9b." Illustrations that are intended to follow the printed text may be termed Plates, and any components should be similarly lettered and referenced: "Plate 9b." Keys to any symbols within an illustration should appear on the art rather than in the legend. Some points of style: Do not use periods after such abbrevi- ations as "mm, ft. USNM, NNE." Spell out numbers "one' through nine" in expository text, but use digits in all other cases if possible. Use of the metric system of measurement is preferable; where use of the English system is unavoidable, supply metric equiva- lents in parentheses. Use the decimal system for precise meas- urements and relationships, common fractions for approximations. Use day/month/year sequence for dates: "9 April 1976." For months in tabular listings or data sections, use three-letter abbre- viations with no periods: "Jan, Mar, Jun," etc. Omit space between initials of a personal name: "J.B Jones." Arrange and paginate sequentially every sheet of manu- script in the following order: (1) title page. (2) abstract, (3) con- tents, (4) foreword and/or preface, (5) text, (6) appendixes, (7) notes section, (8) glossary, (9) bibliography (10) legends, (11) tables. Index copy may be submitted at page proof stage, but plans for an index should be indicated when manuscript is sub- mitted. i
