The 216 primary and secondary types appear under headings of class, order, family and the current generic name. For each species or subspecies, the original description is cited; also the first-published name is given if revision has occurred. Literature references are provided for name changes or where the species has been relegated to synonymy. There are 64 families represented from localities in 13 countries, the Arctic Ocean, north and south Atlantic Ocean, Chukchi Sea, Labrador Sea and the north and south Pacific Ocean. Résumé La liste des spécimens de mollusques désignés comme types dans la collection de la Division de la Zoologie des Invertébrés du Musée national des sciences naturelles contient un bref commentaire sur les origines de la collection de mollusques et des procédures de conservation des types. Les 216 types primaires et secondaires sont placés sous les titres de classe, ordre, famille ; on fournit aussi le nom générique courant. La description originale est citée pour chaque espèce et sous-espèce ; de plus, le nom le plus ancien apparaît s’il y a eu une révision. Des références sont fournies pour les changements de noms ou dans les cas où l’espèce a été reléguée à la synonymie. Cet ouvrage porte sur 64 familles qui proviennent de 13 pays, l’océan Arctique, le nord et le sud de Pocéan Atlantique, la mer Tchuckchi, la mer du Labrador et le nord et le sud de l’océan Pacifique. Introduction The Museum of Natural Sciences in Ottawa has a worldwide mollusc collection of more than two and a half million dry and preserved specimens. It is considered the fifth largest in North America, with collections from Atlantic, Pacific and Arctic waters as well as native and exotic terrestrial species. The Canadian freshwater fauna is particularly well represented. Our type holdings contain specimens from the Arctic Ocean, north and south Atlantic Ocean, Chukchi Sea, Labrador Sea and the north and south Pacific Ocean. The countries represented are Angola, Bahama Islands, Canada, Cuba, Japan, Mexico, New Zealand, Peru, Society Islands (France), South Sandwich Islands (U.K.), Trinidad and Tobago, and the United States. Type specimens are of paramount importance in taxonomic work as these are the specimens on which the description of each species or sub- species is based. They become standards for subsequent identification and nomenclature of the species. The International Commission on Zoological Nomenclature in its International Code of Zoological Nomenclature (London, 1964), currently being revised, has established strict rules for the presentation of a proposed new species, including the obvious value of an accompanying illustration. It emphasized the need to deposit types in a scientific institution to be secure for posterity. For all nominal species or subspecies the type specimens are defined as follows: Holotype: Either a unique specimen or the specimen selected by the author from the type-series to represent the described species. Syntype: The name applied to all specimens in the original type-series when a holo- type has not been selected by the author. Paratypes: The remaining specimens (if any) in the type-series after the holotype has been designated. Lectotype: If no holotype exists, one of the syntype or paratype specimens may subsequently be designated as the lectotype of that species. Neotype: If all specimens in the original type- series have been lost or destroyed and no holotype, lectotype or syntype exists, an author doing revisory work may designate a substitute type specimen, called the neotype. The ICZN (1964) lists 6 conditions to be observed to ensure the validity of this type designation. Topotype: Specimen(s) from the type locality but not part of the original type-series. In the National Museum of Natural Sciences the mollusc types are kept separated from the main collection and to date 216 types have been segregated. Topotypes are marked but remain in the main collection. Each type lot has a regular museum label showing catalogue number, name, locality, date collected and the accession number, with a red strip added, on which the type category is marked. The catalogue number, on a separate slip inserted with the specimen(s), is marked in red. The nature of the specimen (preserved or dry) is also indicated in the catalogue. The Invertebrate Zoology Division does not lend primary types unless exceptional circumstances require that such a type be hand carried to another museum for further study. Researchers are wel- come to examine these specimens in the Mollusc Section. Paratypes may be borrowed by workers connected with museums or other research institutions. In this report the entries are divided into marine and non-marine categories under headings of class, order and family with the genera listed alphabeti- cally. For each species or subspecies, the author, date of publication, page number and plate or figure reference is cited. The type category, catalogue number, number of specimens and if dry or in alcohol (having soft parts) is given, as well as the collector and date. Under locality, the original description is given, with any added geographic information in parentheses. Metric equivalents also have been inserted. The country of origin is included for all non-Canadian collections. In the case of paratypes, the institution holding the holotype (if known) is mentioned in Remarks. Information on taxonomic name changes is provided. Species are listed under their current generic name, with the originally-published name given in square brackets. The author and literature reference for the change appears under Remarks. In some instances the species name has been relegated to synonymy and this is noted with a reference to the authority and where published. The abbreviated references in the text are listed in full in Literature Cited. Authorities for generic names in the headings are not cited. In the early days of Canadian malacology extensive collections were made by members of the Geological Survey of Canada in the course of their work. Some early publications refer to mollusc types being deposited in the ‘Geological Survey” which at that time included the National Museum. In 1950, the Recent mollusc collection was trans- ferred from the Geological Survey to the Biological Division of the National Museum of Canada (Russell, 1961) and is now maintained in the Mollusc Section of the Invertebrate Zoology Division of the National Museum of Natural Sciences. Type material has been received from various sources, including the original collectors, expedi- tions, museum exchanges and, in recent years, from the authors of new species. The addendum of ‘‘doubtful” type specimens, 11 in number (p. 24), is included because the speci- mens, when received, were labelled and catalogued as types. In some instances, the original descriptions of these taxa have not yet been located or some aspect of the accompanying data appears questionable; pending further investigation their status is uncertain.

Pisidium Pfeiffer 1821 Pisidium eyerdami ‘Sterki Herrington, 1954:132 (synonymized with P. casertanum (Poli)). PARATYPES NMC 22556 (24 dry) Locality: Three Saints Bay, Kodiak Island, Alaska, USA. In a brackish pond Collector: W.J. Eyerdam, August 1931 Remarks:. Specimens from this location were sent to Nils HJ. Odhner, labelled as paratypes of P. eyerdami Sterki, but Odhner (1939:81) could find no record of publication and con- sidered the specimens to be Pisidium cinereum Alder (= casertanum Poli). Pisidium fallax Sterki, 1896:20. SYNTYPES NMC 4596 (6 dry) Locality: Tuscarawas River, Ohio, USA Collector: V. Sterki, October - November 1891 Remarks: Herrington (1962:38) used speci- mens from UMMZ for his redes- cription of this species. Pisidium medianum minutum Sterki, 1899:11. SYNTYPES NMC 6421 (20 dry) 24 Locality: Hacket’s Mill Brook at tributary to Caribou Stream on the Aroostook River, Maine, USA Collector: O. Nylander Remarks: P. medianum Sterki, 1899:10 was synonymized with P. fefrugineum Prime by Herrington (1962:39). Sphaerium Scopoli 1777 Sphaerium lavernense Herrington, 1958. In Herrington & Taylor, 1958:10, pl 1 figs. 4-7. PARATYPES NMC 69061 (21 valves dry) Locality: Laverne Location 1, NE 4 SE % section 1, T3N, R27E, Beaver County, Oklahoma, USA Collector: C.W. Hibbard, et al. Remarks: Holotype in MCZ. “Doubtful Types” ISCHNOCHITONIDAE Ischnochiton Gray 1847 Ischnochiton retiporosus punctatus (Whiteaves, 1887):125 [as Leptochiton punctatus]. SYNTYPE NMC 12335 (1 dry) Locality: Discovery Passage, British Columbia Collector: G.M. Dawson, 1885 Remarks: This specimen is considered a type because all the label data are identical with the information recorded for catalogue number NMC 1021 which is noted as “n.sp.” and (in remarks) “shell gone”. It appears to be part of the original type lot but was catalogued at a later date. Oldroyd (1927c:275) considered this a subspecies; La Rocque (1953:13) and subsequent authors agreed. LITTORINIDAE Littorina Ferussac 1822 Littorina conspersa Philippi, 1847. SYNTYPES NMC 21568 (3 dry) Locality: Mazatlan, Mexico (Pacific Ocean) Collector: Remarks: This species was synonymized with L. modesta Philippi by Keen (1971:366). These specimens (label- led ‘Type”) were presented by J. Ferrier, to the old Montreal Natural History Society which gave its collection to the Perth Munici- pal Museum in 1936. The Perth Museum donated its mollusc collection to the NMC in 1960. BUCCINIDAE Neptunea Bolten 1798 Neptunea stilesi A.G. Smith, 1968:117, pl 14. PARATYPE NMC 47334 (1 dry) (Smith no. NS X) Locality: La Perouse Bank, Washington, USA. Depth 120 fm (219 m) Collector: ?, 1959 Remarks: Holotype in CAS. It is uncertain if the NMC specimen is a paratype, although the label shows Smith identified it: maybe a topotype. TURRITELLIDAE Turritella Lamarck 1799 Turritella (Zeacolpus) ahiparana Powell, 1927:297 as [Zeacolpus ahiparanus]. PARATYPE NMC 4674 (1 dry) Locality: Off Ahipara, New Zealand. Depth 20 fm (36 m) Collector: A.W. Powell Remarks: This may be a paratype as labelled but in the publication 23 fathoms is recorded as the depth. GAIMARDIIDAE Kidderia Dall 1876 Kidderia hamiltoni Finlay, 1926:456. PARATYPES NMC 4640 (3 dry) Locality: Macquarie Island, S Pacific Ocean Collector: “Hamilton Expedition”, 1893 Remarks: Although labelled and catalogued as above, it is more likely that these specimens are topotypes according 25 to information available in the literature. Holotype (?) in the Australian Museum, Sydney. LYMNAEIDAE Lymnaea Lamarck 1799 Lymnaea proxima Lea, 1856:80. PARATYPES NMC 40408 (2 dry) Locality: Arroyo, San Antonio, California, USA Collector: — Remarks: These specimens were received in an exchange from the USNM.

The label indicates these specimens are ‘“‘from the original series” but there is no collector or date. These details are also omitted in Pilsbry’s description. Collector: Remarks: POMATIASIDAE Cyclostoma Draparnaud 1801 Cyclostoma bicolor Gould, 1842: back cover. PARALECTO- NMC 7258 (3 dry) TYPES Locality: Cuba Collector: J. Bartlett Remarks: Gould (1843:138) synonymized this with Cyclostoma auriculatum d’Orbigny. See also Gould (1862: 183) where it is listed as C. (Megalomastoma) auriculatum d’Orbigny. Lectotype in MCZ, selected by R.I. Johnson (1964:46). ENDODONTIDAE Planogyra Morse 1864 Planogyra asteriscus (Morse, 1857):128 [as Helix asteriscus]. IDEOTYPE NMC 3054 (3 dry) Locality: Westbrooke, Maine Collector: E.S. Morse Remarks: Lectotype in MCZ selected by Merrill E. Champion (1947:143). SYSTROPHIIDAE Systrophia Pfeiffer 1855 Systrophia cereonitens Haas, 1951:533, pl 117 A-C. PARATYPES NMC 20649 (5 dry) Locality: Collector: Near San Ignacio, W of Rio Chinchipe, Peru.
