THE VELIGER Scope of the journal The Veliger is open to original papers pertaining to any problem concerned with mollusks. This is meant to make facilities available for publication of original articles from a wide field of endeavor. Papers dealing with anatomical, cytological, distributional, eco- logical, histological, morphological, physiological, taxonomic, evolutionary, etc., aspects of marine, freshwater, or terrestrial mollusks from any region will be considered. Short articles containing descriptions of new species or lesser taxa will be given preferential treatment in the speed of publication provided that arrangements have been made by the author for depositing the holotype with a recognized public Museum. Museum numbers of the type specimen must be included in the manuscript. Type localities must be defined as accurately as possible, with geographical longitudes and latitudes added. Very short papers, generally not exceeding 500 words, will be published in a column entitled “NOTES, INFORMATION & NEWS”; in this column will also appear notices of meetings, as well as news items that are deemed of interest to our subscribers in general.

Caudofoveata, Polyplacophora, Bivalvia, Scaphopoda, and Cephalopoda by PAUL H. SCOTT, F. G. HOCHBERG, and BARRY ROTH Department of Invertebrate Zoology, Santa Barbara Museum of Natural History, 2559 Puesta del Sol, Santa Barbara, California 93105, USA Abstract. The non-gastropod molluscan types currently housed in the Department of Invertebrate Zoology at the Santa Barbara Museum are listed. Three hundred seventeen type lots are reported, representing 211 recent species and 9 species originally described as fossils. Each type lot recorded includes a complete citation, type locality, and the current type status of the specimens. An author index and alphabetic index are provided. Lectotype designations are made for three species: Mopalia chacei Berry, 1919; Placiphorella pacifica Berry, 1919; and Venus fordii Yates, 1890. INTRODUCTION In the past five years the Santa Barbara Museum of Nat- ural History has added approximately 1400 primary mol- luscan type lots to its holdings. The majority of these specimens were contained in the extensive mollusk collec- tion of the late S. Stillman Berry, which the museum received in 1985 (Hochberg, 1985). Many of the types represent species described by Berry (for a complete listing of Berry’s taxa see Sweeney & Roper, 1984). Also in- cluded are a number of important species from the eastern Pacific Ocean that Berry obtained through exchange with the United States National Museum of Natural History, the Harvard University Museum of Comparative Zoology, and the Philadelphia Academy of Natural Sciences. Types acquired in exchange by Berry include species described by P. P. Carpenter, C. B. Adams, VV. H. Dali, and many other authors. The Department of Invertebrate Zoology at the Santa Barbara Museum of Natural History was formally estab- lished in 1958, although the museum was founded in 1916. A number of important mollusk collections, donated in the early 1940s, form the nucleus around which the depart- ment was organized. The current shelled mollusk collec- tion contains about 180,000 species lots. With the addition of cephalopods from the Allan Hancock Foundation our current holdings of octopuses and squids totals over 7000 species lots. A number of mollusk paratypes and hypotypes were destroyed in a fire at the museum in 1962. SPHON (1962) detailed the types lost in the fire and later (SPHON, 1966) published an updated list of types housed in the depart- ment. Several works on the molluscan taxa of selected authors were consulted during the compilation of this catalog. Hertz (1984) illustrated the types of S. S. Berry that were described in his Leaflets in Malacology. The species de- scribed by H. N. Lowe, and descriptions Jointly authored by H. A. Pilsbry & Lowe, are listed in Hertz (1986), along with illustrations of previously unfigured types. Names introduced by H. A. Pilsbry are listed in Clench & Turner (1962). Turner (1956) listed and illustrated the eastern Pacific species of C. B. Adams, and included many lectotype designations. W. H. Dali’s taxa are listed in Boss et al. (1968). Palmer (1958, 1963) and Keen (1968) discussed the eastern Pacific taxa of P. P. Carpenter and provide numerous type illustrations. FORMAT This catalog lists primary types (holotypes, paratypes, syn- types, neotypes, lectotypes, and paralectotypes) of recent Page 2 The Veliger, Vol. 33, Suppl. 1 and fossil mollusks in the classes Caudofoveata, Polypla- cophora, Bivalvia, Scaphopoda, and Cephalopoda. Records of the gastropod types will be included in a future catalog. Types not regulated by the International Code of Zoological Xomenclature (Ride et al., 1985) (hereafter ICZX), in- cluding hypotypes and plaster casts of types, are excluded. The catalog is arranged systematically by class, subclass or order, and family. Species-group names are arranged alphabetically within each family. Two indices are pro- vided: an author index that lists all taxa described by a given author, and an alphabetic index by species-group name. The format for each species-group name is as follows: species. Genus {Subgenus) Author, date: Original citation. Type category: Catalog number (number of specimens, preservative); last catalog number if any. Locality as published in original description. Remarks: Lectotype information, specimen condition, other previous catalog numbers, etc. The following general guidelines are used: Genus-group names are as originally proposed and do not include new combinations. Family-group names are those currently used in the literature. Bernard (1983) w'as the primary source for families of the Bivalvia, Kaas & V'an Belle (1980) and Van Belle (1981) for the Polyplacophora, Voss (1977) and Cl.arke (1988) for the Cephalopoda, and Boss (1982) for the Caudofoveata and Scaphopoda. The original citation includes only figures and plates that illustrate actual specimens in the collection of the Santa Barbara Museum of Natural History. The type series is the most difficult category to delin- eate. The ICZX (Ride et ai, 1985) was used as our guide- line. We have tried to use the code conservatively to avoid subsequent confusion with the status of a type series. Each type lot was categorized using the following definitions. Holotype — the single specimen designated by the au- thor to be the name-bearing type in the original pub- lication. In a few instances we have demonstrated that a species-group taxon was based on a single specimen and have designated the holotype by monotypy [7CZA’ .\rt. 73a (ii)]. Paratypes — all specimens remaining in a type series after a holotype has been designated, or other speci- mens designated as paratypes in the original descrip- tion. Syntypes — all specimens in a type series in w'hich nei- ther a holotype nor a lectotype has been designated. Lectotype — a specimen in a type series that has been designated by a subsequent author as the name-bear- ing type. This includes specimens that have been in- advertently referred to in print as the “holotype” or “the type” {ICZX Art. 74b). We have attempted to trace the current status of each species group and include lectotype designations, although some desig- nations may have been overlooked. Lectotype (herein) — In several instances S. S. Berry neglected to designate types in the original publication, but labeled his specimen as the “Type” or “Holotype” and entered them as such in his collection catalog. We feel the authors intent was clear for these type spec- imens and have chosen to designate lectotypes in ac- cordance with ICZX Art. 74a. We have also desig- nated a lectotype for one species described by L. G. Yates. Paralectotypes — all specimens remaining in the type series after a lectotype has been designated. The number of specimens in each type lot is stated and, where applicable, information on incomplete speci- mens (single valves or plates, etc.) is included. Bivalves are listed as a matched pair of valves (pair) or as single un- matched valves (valves). In a few cases a dash (-) in this section indicates that the specimen is represented by a small fragment. Such cases are further mentioned in the remarks section. The current preservative is either a dried shell body (dry), 70% ethyl alcohol (70% EtOH), or balsam. The immediately previous catalog number is given when available. Other previous numbers are given in the remarks section. S. S. Berry frequently gave his chiton specimens two numbers. The first number is his general catalog number, the second [in brackets] is a chiton catalog number. The locality is as published in the original description and may include additional information from the specimen label. We have included current higher geographic cate- gories (country, state, province, etc.) to maintain a consis- tent format. In addition, if station numbers were given in the original description {e.g., United States Fish Commis- sion Stations) we have included the latitude and longitude, or bearing of the station when available. Localities in the United States begin with the state in uppercase; localities in other countries or oceans begin with the country or ocean in uppercase. Anglicized names have been changed to their proper place name {e.g., Angeles Bay is changed to Bahia de los Angeles). If a place name is no longer in common use we have provided the currently accepted name in brackets. Metric equivalents have been included in brackets if non-metric units of measurement were included in the original description or label. The remarks include reference to lectotype designations and anyAmportant data not mentioned in the above cat- egories. When available we have included the current re- pository of the holotypes and lectotypes for those taxa that the Santa Barbara Museum of Natural History houses only paratypes or paralectotypes.

If computer generated copy is to be submitted, margins should be ragged right (i.e., not justified). To facilitate the review process, manuscripts, including figures, should be submitted in triplicate. The first mention in the text of the scientific name of a species should be accompanied by the taxonomic authority, including the year, if possible. Underline scientific names and other words to be printed in italics. Metric and Celsius units are to be used. The sequence of manuscript components should be as follows in most cases: title page, abstract, introduction, materials and methods, results, discussion, acknowledgments, lit- erature cited, figure legends, figures, footnotes, and tables. The title page should be on a separate sheet and should include the title, author’s name, and address. The abstract should describe in the briefest possible way (normally less than 200 words) the scope, main results, and conclusions of the paper. Literature cited References in the text should be given by the name of the author(s) followed by the date of publication: for one author (Smith, 1951), for two authors (Smith & Jones, 1952), and for more than two (Smith et ai, 1953). The “literature cited” section must include all (but not additional) references quoted in the text. References should be listed in alphabetical order and typed on sheets separate from the text. Each citation must be complete and in the following form: a) Periodicals Cate, J. M. 1962. On the identifications of five Pacific Mitra. Veliger 4:132-134. b) Books Yonge, C. M. & T. E. Thompson. 1976. Living marine molluscs. Collins: London. 288 pp. c) Composite works Feder, H. M. 1980. Asteroidea: the sea stars. Pp. 117-135. In: R. H. Morris, D. P. Abbott & E. C. Haderlie (eds.). Intertidal invertebrates of California. Stanford Univ. Press: Stanford, Calif. Tables Tables must be numbered and each typed on a separate sheet. Each table should be headed by a brief legend. Figures and plates Figures must be carefully prepared and should be submitted ready for publication. Each should have a short legend, listed on a sheet following the literature cited. Text figures should be in black ink and completely lettered. Keep in mind page format and column size when designing figures. Photographs for half-tone plates must be of good quality. They should be trimmed off squarely, arranged into plates, and mounted on suitable drawing board. Where necessary, a scale should be put on the actual figure. Preferably, photographs should be in the desired final size. It is the author’s responsibility that lettering is legible after final reduction (if any) and that lettering size is appropriate to the figure. Charges will be made for necessary alter- ations. Processing of manuscripts Upon receipt each manuscript is critically evaluated by at least two referees. Based on these evaluations the editor decides on acceptance or rejection. Acceptable manuscripts are returned to the author for consideration of comments and criticisms, and a finalized manuscript is sent to press. The author will receive from the printer two sets of proofs, which should be corrected carefully for printing errors. At this stage, stylistic changes are no longer appropriate, and changes other than the correction of printing errors will be charged to the author at cost. One set of corrected proofs should be returned to the editor. An order form for the purchase of reprints will accompany proofs. If reprints are desired, they are to be ordered directly from the printer. Send manuscripts, proofs, and correspondence regarding editorial matters to: Dr. David W. Phillips, Editor, 2410 Oakenshield Road, Davis, CA 95616 USA.
