The first lists alphabetically 124 genus-group taxa originally proposed or later included within the superfamily as well as 24 misspelled or nude names. The second section lists alphabetically 1,864 species-group names proposed in or subsequently referred to genera now considered to belong in Cancellarioidea. Also listed are 392 nude names, misspellings and incorrect attributions. The third section consists of a bibliography of works referred to in this paper. Key words: Cancellarioidea, genus-list, species-list, bibliography Accepted by D. Geiger: 15 Sept. 2005; published: 19 Dec. 2005 3 ZOOTAXA Introduction 1102 The first edition of this catalogue was published in 1990. Since that time numerous new species have been named and several changes in classification have been made affecting the list of genera. Also, as with any catalogue of molluscan taxa, the first edition was not only incomplete, but contained errors, principally in determining the correct dates of some publications. The Cancellarioidea comprise a highly-specialized, poorly known, and still taxonomically enigmatic group of marine neogastropods that inhabit subtidal to bathyal sand and mud bottoms of tropical and temperate latitudes. Although most taxa at all levels within the superfamily were described on the basis of shell characters, it was a series of adaptations to suctorial feeding that resulted in a succession of adaptive radiations beginning during the late Mesozoic that gave rise to the Cancellarioidea. Diagnostic synapomorphies of the superfamily include: an anteriorly tubular, posteriorly saddle- shaped jaw that spans the dorsal surface of the buccal mass; a uniserial radula composed of extremely elongated (L/W >15), ribbon-like, tricuspid teeth with secondary dentition on one or more cusps [there are several aradulate taxa]; an extremely short anterior esophagus, with the valve of Leiblein and buccal ganglia situated at the posterior margin of the buccal mass; and the lack of a gland of Leiblein. Although the superfamily forms a monophyletic and morphologically compact natural assemblage, its relationships to other caenogastropods remains uncertain. The group had, at various times, been included in the Toxoglossa (Troschel 1865; Tryon 1882; Fischer 1883), the Volutoidea (Thiele 1929; Wenz 1943; Taylor and Sohl 1962) and its own order, Nematoglossa (Olsson 1970). Most subsequent authors (reviewed in Harasewych & Petit 1998) follow Ponder (1974) in considering the Cancellarioidea a superfamily within Neogastropoda. Taylor et al. (1980) speculated that the Cancellarioidea are an early offshoot from the Mesozoic Purpurinidae. Linnaeus (1758), in the Tenth Edition of his Systema Naturae, described a single species of cancellariid, including it in the genus Murex. In 1767 he transferred that species to Voluta and described a second species, also as Voluta. By the end of the 18th century, twelve nomina had been proposed for cancellarioideans, allocated to the genera Murex, Voluta, Tritonium, Buccinum and Cantharus. To date, there have been over 1,800 species- group taxa proposed in the Cancellarioidea, many as ’varieties’ of Tertiary species. Lamarck (1799) was the first to recognize that the then known cancellariids comprised a distinct group and erected the genus Cancellaria. The second genus-group name to be proposed for a cancellariid was Trigona Perry, 1811 (preoccupied and replaced by the equivalent Trigonostoma Blainville, 1827). The third genus-level name to be introduced was Admete (Kröyer in Möller, 1842). A decade or so later, the flood-gates opened and many new genera and subgenera were introduced. Marks (1949) published a list of supra- specific taxa in Cancellariidae, citing 58 nominal taxa. We now list 124 nominal genus- group taxa as well as 24 misspellings and nomina nuda. Ten of these nomina are junior objective synonyms and/or junior homonyms, one has been rejected by the I.C.Z.N., one is 4 © 2005 Magnolia Press PETIT & HARASEWYCH an emendation and six were originally proposed in Cancellariidae but belong elsewhere. ZOOTAXA Of the five added since 1990, three were proposed in other families and later transferred to 1102 Cancellariidae; one Paleocene genus was described in 1989 but not seen by us until after the list was in press; and one Recent genus was described after the publication of the 1990 catalog. Some of these 124 nomina are synonyms and others are poorly known. Genus- group taxa proposed for cancellariids have not been treated uniformly in the literature as authors have differed widely in their use of available taxa. As noted by some authors, many of the nominal genera and subgenera of cancellariids seem to be unnecessary. At the same time, there are numerous species that do not readily fit any of the named taxa. Dall (1909a: 30) wrote: “I may add that what, on a cursory survey, appears to be a totally unnecessary number of names has been applied to subdivisions of the genus Cancellaria; but time fails me at present to review them in detail. Most of them are based on slight modification of form which gradually merge into one another when a full series of specimens is considered.” As an aid to the production of badly needed systematic revisions of this poorly- understood superfamily, it has been our objective to compile and maintain a list of all names proposed or currently used for cancellarioideans. We have endeavored to make this work as complete as possible, but recognize that some taxa have undoubtedly been omitted. We request that colleagues bring to our attention any errors and omissions, which will be published in a future addendum. This catalogue of superfamily Cancellarioidea is composed of three sections: an alphabetical listing of genus-group taxa, an alphabetical listing of species-group taxa, and a bibliography of the references cited herein. The genus-group list contains all taxa at the genus-group level, as defined by Article 42 of the International Code of Zoological Nomenclature (Fourth Edition 1999), that have been referred to the Cancellarioidea or any of its families or subfamilies, either originally or subsequently. Genus-group taxa originally proposed in Cancellarioidea but later referred to other superfamilies are included in our list of genera, but the species described in those genera are not included. The species-group list contains all taxa proposed at the species-group level as defined by Article 45 of the International Code of Zoological Nomenclature (Fourth Edition 1999). Names originally proposed as subspecies, varieties, forms or other infrasubspecific categories are included, with the category used by the author identified. We have listed all names originally proposed in, or now considered as being referable to, genera presently included in Cancellarioidea. Nude names (nomina nuda), excluded from some lists of taxa, are included here, as they have appeared in print and may cause confusion if their status is unclear. However, only names that appeared in print are included and names appearing only on museum labels or on websites are not. This is a non-critical list with subjective synonyms being shown only for a few taxa. We stress that it is non-critical as numerous people have inquired about the placement of various species, mistaking the original generic placement as our determination.

Since that time considerable revision in nomenclature has taken place, and some further material has come to hand. As descriptions and references to the family are very scattered in literature, the opportunity is now taken to bring them together, and to illustrate not only species new to science, but also all those which have already been described. It is felt that such papers are of great convenience to conchologists and form a base on which future work can be under­ taken.

INTRODUCTION Cancellaria minima Reeve, 1856, is a poorly known species from off Madei- ra and the Atlantic coast of the southern Iberian peninsula. It was described (Reeve, 1856: species 77) after specimens of Cuming's collection, from an un- known locality. The syntypes are kept in the British Museum (Natural History [= BM], no. 1968410; although the label mentions four specimens, only three shells are present. Monterosato (1878: 97, note 2), for the first time, gave a locality for C. mi- nima, referring to "C. minima H. Adams, delle Canarie". Jeffreys (1885: 49), reporting on the material of the "Porcupine"-expeditions, mentioned five spe- cimens from off the Gulf of Cadiz; he also referred to specimens found at Madeira, Gibraltar and the Canary Islands by McAndrew.

  • Otago Submarine Canyons: Mapping and Macrobenthos
    Otago Submarine Canyons: Mapping and Macrobenthos Bryce A. Peebles A thesis submitted in partial fulfilment for the degree of Master of Science at the University of Otago December 2013 ii Abstract Submarine canyons are steep-sided “V’ or “U” shaped valleys that incise continental slopes worldwide. The geophysical and oceanographic features of submarine canyons can produce environmental conditions that cause benthic assemblages to be distinctive and productive compared to those of the adjacent slope; however the assemblages are potentially vulnerable to anthropogenic impacts, including bottom fishing. In order to help inform policy and management, submarine canyons need to be objectively defined topographically and their benthic assemblages characterised. A canyon network occurs off the Otago Peninsula, south-eastern New Zealand, but lack of detailed bathymetric data and adequate benthic sampling has limited study of the canyons. This thesis outlines a method of defining submarine canyon areas and examines epifaunal and infaunal assemblages of the Otago canyons and adjacent slope. Objective definition of the Otago canyon network in the GIS software GRASS along with the steps to use this methodology worldwide are described. Archival count data from 1966-74 on the epifauna are analysed using the PRIMER suite of programs to characterise epifaunal assemblages. Anomurans, polychaetes, asteroids and ascidians make up 70% of the epifaunal canyon assemblage. The epifaunal assemblage is clearly defined by water depth and recognisable from 380 m. Quantitative sampling of infauna in Saunders canyon, Papanui canyon and adjacent slope was carried out to examine infaunal community structure of the canyons and adjacent slope. Infaunal canyon assemblages are dominated by polychaetes, amphipods, ophiuroids, decapods and isopods in canyons, accounting for 75% of collected individuals.

In freshwater Pul- monata, such as Limnaea, cilia on the foot assist in feeding when the animal is creeping suspended from the surface film (Brockmeier, 1898). Thecoso- matous Pteropoda feed exclusively by the aid of cilia on the unpaired middle lobe and the paired side lobes of the foot, and an evolutionary series- Cavolinia-Cymbulia-Gleba-can be traced in which there is a progressive elaboration in the perfection of this mechanism and an accompanying reduc- tion in the buccal mass and associated structures handed down from carni- vorous ancestors (Yonge, 1926). Only in the few prosobranchs which have acquired ciliary feeding mechanisms do these represent a modification of the ctenidia as in the Lamellibranchia. They also, as it is the aim of this paper to show, represent a modification of the rejection currents present in the mantle cavity of typical prosobranchs. REJECTION CURRENTS IN THE MANTLE CAVITY OF THE PROSOBRANCHIA In typical Prosobranchia a respiratory current, created by the beating of the lateral cilia on the gill filaments, is drawn into the mantle cavity by way of the inhalent opening (frequently prolonged into a siphon, e.g.

Conids are well known for being active predators on worms, fishes, and even other snails. Cones are venomous gastropods, meaning that they use a sophisticated cocktail of hundreds of toxins, named conotoxins, to subdue their prey. Although this venom has been studied for decades, most of the effort has been focused on Indo-Pacific species. Thus far, Atlantic species have received little attention despite recent radiations have led to a hotspot of diversity in West Africa, with high levels of endemic species. In fact, the Atlantic Chelyconus ermineus is thought to represent an adaptation to piscivory independent from the Indo-Pacific species and is, therefore, key to understanding the basis of this diet specialization. We studied the transcriptomes of the venom gland of three individuals of C. ermineus. The venom repertoire of this species included more than 300 conotoxin precursors, which could be ascribed to 33 known and 22 new (unassigned) protein superfamilies, respectively. Most abundant superfamilies were T, W, O1, M, O2, and Z, accounting for 57% of all detected diversity.

  • Comparative Anatomy of Four Primitive Muricacean Gastropods: Implications for Trophonine Phylogeny
    ^/ -S/ COMPARATIVE ANATOMY OF FOUR PRIMITIVE MURICACEAN GASTROPODS: IMPLICATIONS FOR TROPHONINE PHYLOGENY M. G. HARASEWYCH DEPARTMENT OF INVERTEBRATE ZOOLOGY NATIONAL MUSEUM OF NATURAL HISTORY SMITHSONIAN INSTITUTION WASHINGTON, D.C. 20560, U.S.A. ABSTRACT The main features of the shell, head-foot, palliai complex, alimentary and reproductive systems of Trophon geversianus (Pallas), Boreotrophon aculeatus (Watson), Paziella pazi (Crosse), and Nucella lamellosa (Gmelin) are described, and phonetic and cladistic analyses based on subsets of these data presented. Similarities in shell morphology revealed by phenetic studies are interpreted as being due to convergence, and are indicative of similar habitats rather than of close phylogenetic relationships. Convergences are also noted in radular and stomach characters. Cladistic analyses of anatomical data support the following conclusions: 1 ) Thaididae are a primitive and ancient family of muricaceans forming a clade equal in taxonomic rank with Muncidae; 2) Within Muricidae, P. pazi more closely resembles the ancestral muricid phenotype than any trophonine; 3) Trophoninae comprise a comparatively recent monophyletic group with differences due to a subsequent austral adaptive radiation. The Muricidae are considered to be the most primitive and D'Attilio, 1976:13) a personal communication from E. H. family within Neogastropoda according to most (Thiele, Vokes "it appears likely that the most northern trophons are 1929; Wenz, 1941; Taylor and Sohl, 1962; Boss, 1982) but derived from the Paziella-Poiheha line, and that the several not all (Golikov and Starobogatov, 1975) recent classifica- austral forms that are unquestionably "trophonine" are prob- tions. Of the five subfamilies of Muricidae, the Trophoninae, ably derived from the Thaididae". proposed by Cossmann (1903) on the basis of shell and Thus, according to most published work, the Tropho- opercular characters to include a number of boreal and ninae are in a position to shed light on the systematics and austral species, are the most poorly understood.
