CATALOG OF RECENT MOLLUSCAN TYPES IN THE NATURAL HISTORY MUSEUM OF LOS ANGELES COUNTY compiled by Lindsey T. Groves NATURAL HISTORY MUSEUM OF LOS ANGELES COUNTY MALACOLOGY SECTION 900 Exposition Boulevard, Los Angeles, California, 90007, USA [email protected] [last updated 3 January, 2012] Abstract. Recent molluscan types currently housed in the Malacology Section of the Natural History Museum of Los Angeles County are listed herein. Each type lot entry includes original species/subspecies name, original genus, author, original citation, type status, LACM number, number of specimens and preservation, type locality or collection locality, collector [if known], date collected [if known], and current taxonomic status if different from original description. INTRODUCTION This catalog is published in accordance with Recommendation 72F.4 of the International Code of Zoological Nomenclature (Ride & others, 2000:79). This listing includes all molluscan type material currently housed at the Natural History Museum of Los Angeles County and supercedes the type listing of Sphon (1971). To date 1922 molluscan type lots (71,000+ specimens) are reported for 1147 species and 99 subspecies, which includes 589 holotypes, 1277 paratype lots, 10 lectotypes, 13 paralectotype lots, 29 syntype lots, 3 neotypes, and 2 neotype lots in 550+ references. Type categories listed include: Holotype (in red), paratype(s) (in blue), syntype(s) (in orange), lectotype (in pink), paralectotype(s) (in aqua), and neotype and/or neotype lots (in brown) as defined by Ride & others (2000). Because the term cotype is not recognized by the ICZN, lots originally designated as cotype(s) (in green) by original specimen labels are now referred to as syntype(s). Hypotypes (or figured non-type specimens) are not housed within the type collection and are considered voucher specimens. Species are listed alphabetically within each family regardless of subfamily and/or genus. Classifications schemes are according to Coan & others (2000) for the bivalves, Bouchet & others (2005) for the gastropods, Steiner & Kabat (2001) for the scaphopods, Sirenko (2006) for the polyplacophorans, Scheltema (1998) for the aplacophorans, and Warén & Gofas (1996) for the monoplacophorans. These arrangements are utilized for convenience as classification schemes are subject to change. Brief History of the Type Collection The LACM Recent Molluscan type collection was started by George Willett (then LACM curator of Ornithology & Mammalogy) in the late 1920’s who organized a separate sequence (ie., a unique lot number for each type lot) and his mollusk types became the core of the LACM Recent type catalog. The type collection grew tremendously following the arrival in 1964 of James H. McLean, the first full-time curator of Malacology, due to his diligent collecting and numerous publications. Since Jim’s retirement in 2001, the type collection has experienced sustained growth, especially the opisthobranch types, under former curator Ángel Valdés. It is obvious from the following list that the LACM malcology type collection has greatly benefited from its relationship with numerous professional and amateur malacologists and conchologists of the past and present who have either donated type material and/or utilized the world-class LACM mollusk collection for their research purposes. Notable living type species authors include James H. McLean (Gastropoda), Eugene V. Coan (Bivalvia), Louie N. Marincovich, (Gastropoda), Bret K. Raines (Gastropoda), Roger N. Clark (Polyplacophora), Daniel L. Geiger (Vetigastropoda), Barry Roth (terrestrial Gastropoda), William K. Emerson (Gastropoda), Peter Jung (Gastropoda & Bivalvia), Thomas A. Burch (Gastropoda & Bivalvia), Hans Bertsch (Opisthobranchia), and most recently Ángel Valdés (Opisthobranchia). Prominent molluscan type authors of the past include Twila Bratcher (Terebridae), Wendell O. Gregg (terrestrial Gastropoda), Helen DuShane (Epitoniidae), Frank R. Bernard (Bivalvia), Dwight W. Taylor (Gastropoda & Bivalvia), LeRoy Poorman (Gastropoda), George Willett (Gastropoda), S. Stillman Berry (Gastropoda), Antonio J. Ferreira (Polyplacophora), Leo G. Hertlein (Gastropoda), John Q. Burch (Gastropoda & Bivalvia), Herbert N. Lowe (Gastropoda), Donald R. Shasky (Gastropoda), Archibald M. Strong (Gastropoda), Gilbert Grau (Bivalvia), and Crawford N. & Jean M. Cate (Cypraeoidea & Mitridae) Historical paratype and syntype material acquired through collection donations and/or purchases includes authors such as William H. Dall, Thomas Say, Henry A. Pilsbry, Carlos de la Torre, Paul Bartsch, George B. Sowerby III, Tom Iredale, Henry Hemphill, and Hugh C. Fulton. Type Collection Usage and Donations The LACM type collection is arranged numerically and housed in locked cabinets. A complete inventory of the type collection is available in the database and reports can be generated as with non-type specimens. A staff member must be present when type material is being studied. Type specimens may be borrowed by bonafide researchers for a period of six months and renewal of type loans are subject to approval by the curator. LACM type numbers may be requested from the collection manager whether or not the specimens originated in the LACM collection. Researchers who wish to deposit type specimens at LACM must provide identified specimens with as complete locality data as possible upon deposition including depth or altitude, habitat, specific locality, coordinates, collector and/or research vessel name, field number, collection date, etc. This data can be in the form of log books, field notes, specimen labels, etc. Type numbers will be assigned after specimens are received by the LACM Malacology section. The donor will agree to sign and date a LACM Deed of Gift form, which gives LACM legal ownership or title. The donor will receive a copy of this form when the accession process is completed along with acknowledgement from the LACM President/Director if desired. The collection manager will process the donation and file an Accession Data Sheet with the Deed of Gift with the LACM Registrars office. All donations to LACM are tax deductible.
