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.

Introduction

This paper continues a series of publications (Vari and Howe, 1991; Springer et al., 1991; Collette et al., 1992) listing the type specimens of various groups of Recent fishes in the Division of Fishes, National Museum of Natural History, Smithsonian Institution. These listings were prepared in response to Recommendation 72G(4) of the International Code of Zoological Nomenclature (ICZN) that “every institution in which name-bearing types are deposited should publish lists of name-bearing types in its possession or custody.” Vari and Howe (1991) outlined the history of the collections in the Division of Fishes, and of the use of the acronym USNM for the collections of recent fishes in the National Museum of Natural History. We refer readers to that publication for a discussion of those topics.

This paper is the second to deal with the USNM type specimens of the superorder Ostariophysi, the dominant group of freshwater fishes in the World. The three orders dealt with in this paper differ dramatically both in their distributions and number of included species. The Gonorynchiformes, by far the least speciose of the three orders in the Recent fauna, occurs in the marine, brackish, and sometimes freshwaters of the Indian and Tropical Pacific regions, and in the freshwaters of tropical Africa and the Nile River basin. Gymnotiforms (gymnotid eels) are widespread in the freshwaters of South and Central America. Siluriforms (catfishes), the most speciose group, are common in the freshwaters of North, Central, and South America, Europe, Africa, Asia, and Australia, with some members of two families widely distributed in tropical marine waters.

The type specimens of gonorynchiform, gymnotiform, and siluriform 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 were typically, but not invariably, cited with USNM catalog numbers. Citations of USNM catalog numbers were often lacking for species described in the nineteenth century. Many type specimens were exchanged to the Smithsonian Institution subsequent to publication under a catalog number of another collection. 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 either directly from the Carnegie Museum and Indiana University, or secondarily through the Museum of Comparative Zoology. In addition, syntypes of various species of gonorynchiforms and siluriforms were received in exchange from The Natural History Museum, London and the Muséum National d'Histoire Naturelle, Paris. This listing serves to bring those and other specimens to the attention of interested researchers.

COMMENTS ON MISSING TYPE SPECIMENS OF SPECIES DESCRIBED BY GILL AND GIRARD.—Gill (1858, 1862a, 1870) described various siluriforms with type localities on the island of Trinidad, North America, and the western portions of the Amazon basin, respectively. In these three papers Gill neither cited the depository of the type specimens, nor typically stated the number of specimens on which he based his descriptions. Type series of two species described in Gill's 1858 paper (Hoplosoma aeneum, Hoplosternum Stevardii) are deposited in the collections of the Division of Fishes (see following listing). The type series of the two other siluriform species described in that paper (Callichthys Kneri, Pimelenotus Vilsoni) 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 (1862a) named three species of North American catfishes. The type series of one of these, Amiurus obesus, was located in the collections of the Division of Fishes, but included three specimens rather than the two cited by Gill. The type series of the other two species described in that paper (Ictalurus simpsoni, Noturus occidentalis) were not found in the collections and it is possible that the extra specimen in the type series of Amiurus obesus is a type specimen of one of those species.

Gill described five species of siluriforms from the western portions of the Amazon basin in 1870, again without any indication of where the material was deposited. The type series of four of these (Cetopsis ventralis. Rhamdia dorsalis. Sciades marmoratus, Sorubimichthys Ortoni) were located in the holdings of the Division of Fishes, but no indication was found of the type specimens of the other species of catfish described in that paper (Centromochlus Steindachneri). Vari and Howe (1991:1, 2) noted that the type series of a number of characiform species described by Gill in two of the cited publications are also missing.

Girard (1860) described eleven species of North American freshwater fishes. At least parts of the type series of ten of these were located in the USNM holdings. There is no indication that the type specimens of Pimelodus lynx were deposited in the Division of Fishes, and we have been unable to locate those specimens.

ABBREVIATIONS.—Many of the specimens listed in this catalog were described under USNM catalog numbers. A number of the cited type specimens, however, were deposited in other institutions when the species was described. In some instances specimens originally reported 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 institutions and collections used in those citations.

ACKNOWLEDGMENTS.—This publication was made possible, in part, through a contract to C.J.F. from the Collection Improvement Fund of the National Museum of Natural History, Smithsonian Institution. Thomas M. Orrell, Jeffrey C. Howe, and Susan L. Jewett assisted with numerous aspects of this study at NMNH. Karsten E. Hartel and Horácio Higuchi (MCZ) helped us to resolve numerous questions concerning type specimens received from MCZ. Sarah Granato (AMNH) assisted in locating several rare references. The examination of various type specimens in South American collections was made possible by funding from the Neotropical Lowland Research Program of the International Environmental Sciences Program of the Smithsonian Institution. Bruce B. Collette (National Marine Fisheries Service, Systematics Laboratory), Karsten E. Hartel (MCZ), Horácio Higuchi (MCZ), and Victor G. Springer (NMNH) offered suggestions for the improvement of this paper.

Format

The following template has been used to structure each entry in the “Catalog of Types”.

Genus species (subspecies) Author(s), year:page, figure(s), plate(s).

Type Status

USNM catalog number (number of specimens, range of standard length (gonorynchiforms, siluriforms) or length from snout to posterior end of anal-fin base (gymnotiforms) in mm). Locality (country, department, province or state, specific locality), collector(s), date(s) collected, as stated in the original description, but in standardized presentation.

Remarks: Includes comments on originally cited authorship and year of publication; reference to lectotype, neotype, or paralectotype designation; corrections of originally cited USNM catalog numbers or previous depository and catalog number of specimens; and correction and/or expansion of data on locality, collector, and date collected.

This listing includes all known published gonorynchiform, gymnotiform, and siluriform type-specimens deposited in the collections of the National Museum of Natural History through 1991. The order of listing is alphabetical by order, within order alphabetical by family, and in families alphabetical by genus and then species and subspecies. Genus, species, and subspecies are spelled as in the original description, except that diacritical marks have been deleted as recommended 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 are found in the “Literature Cited.” The classification of gymnotiform families follows Mago-Leccia (1978). Siluriform classification follows Greenwood et al. (1966) with the addition of two subsequently recognized families: Scoloplacidae (Isbriicker, 1980) and Parakysidae (Roberts, 1989b). The families cited as Helogeneidae and Schilbeidae by many previous authors are listed as Helogenidae and Schilbidae following Steyskal (1980:174).

The presented “Type status” is that currently thought correct based on the original description and subsequent literature designations. The categories for primary and secondary types used are holotype, syntype(s), lectotype, neotype, paratype(s), and paralectotype(s) as defined by the International Commission on Zoological Nomenclature (1985), articles 73 and 74. The cited type status for many specimens exchanged to the Smithsonian after publication under the register numbers of another repository is typically based on information in the associated accession records. Discrepancies between the number of specimens originally reported or listed in the USNM ledgers, and those found when the lots were inventoried (1980 and 1985) or at this time are noted under “Remarks.” Types not located during this study are indicated as “MISSING.” Lots totally exchanged to another institution are cited as in the original description, but noted as “EXCHANGED.” The cited length for gymnotiform type specimens is the length from the snout to the posterior end of the base of the anal fin following Mago-Leccia et al. (1985). The cited length for gonorynchiforms and siluriforms is the standard length (SL) in millimeters (mm). Measurements of specimens greater than 100 mm are to whole mm; specimens less than 100 mm are reported to nearest one-tenth mm, except when damaged or contorted specimens do not warrant that level of precision. Comments about lengths under “Remarks” are included when a different length measurement (e.g., total rather than standard length) was used in the original description, or where there is a notable discrepancy between the originally cited length(s) and the present standard or total length(s). Locality is presented as in the original description, with sequence of presentation of data standardized throughout progressing from country to more specific locality data. Modern equivalents for countries are provided in brackets where necessary. Modern, corrected, and more detailed 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 the “Literature Cited.”

Numerous species cited in the following listing were described by Carl H. Eigenmann and his coworkers. Portions of the type series of these species were exchanged to the Smithsonian and other institutions from the Carnegie Museum and Indiana University prior and subsequent to the publication of the original descriptions. Those exchanges typically were not noted in the ledgers of the Indiana University and Carnegie Museum fish collections making it difficult, or more usually impossible, to determine the disposition of the entire type series. Material cited as type specimens in the correspondence associated with exchanges to the Smithsonian is included in the listing except where collection information for the specimens does not agree with that cited 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.

The locality of additional type specimens for species are noted only in two circumstances. First, for type specimens originally cited with USNM catalog numbers that were subsequently exchanged to other institutions. Second, for type specimens originally cited under the catalog number of another institution that were subsequently transferred to Smithsonian Institution. Unresolved questions concerning recognizable species are common in the orders dealt with herein. Thus, it is premature to comment on the validity or possible synonymy of most of these nominal species.

Holotype

USNM 53472 (1, 125 mm). Peru, Río Eten, Eten; P.O. Simons, 1898–1899.

Remarks: Status of this specimen somewhat ambiguous. Starks (1906:770) stated “The type is 155 mm in entire length and the cotype 110. The latter is deposited in the U. S. National Museum, Cat No. 53472; the cotype in Stanford University Museum.” USNM 53472 is 152 mm total length. Thus, it appears that Starks erroneously associated this catalog number with 110 mm total length paratype.

REQUIREMENTS FOR SMITHSONIAN SERIES PUBLICATION

Manuscripts intended for series publication receive substantive review (conducted by their originating Smithsonian museums or offices) and are submitted to the Smithsonian Institution Press with Form SI-36, which must show the approval of the appropriate authority designated by the sponsoring organizational unit. Requests 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 1art″ 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 necessary.

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 bibliographic, should be typed on separate sheets and inserted immediately after the text pages on which the references occur. Extensive 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 language 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 elements, follow the format of recent publications in the series for which the manuscript is intended. Guidelines for preparing bibliography 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 designated 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 abbreviations 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 equivalents in parentheses. Use the decimal system for precise measurements 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 abbreviations 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 manuscript in the following order: (1) title page, (2) abstract, (3) contents, (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 submitted.
