During the Indonesian-Dutch SNELLIUS -II Expedition (1984-1985) to the Indonesian Archipelago 46 pectinacean species were collected from the Flores Sea and Banda Sea (5°52'-9°57'S, 118°12'-123°58'E) at littoral to bathyal depth (835 m). One new pectinid genus, viz. Glorichlamys gen. nov., six new propeamussiids, viz. Parvamussium araneum spec. nov., Parvamussium carbaseum spec. nov., Parvamussium cassium spec. nov., Parvamussium undosum spec. nov., Parvamussium virgatum spec. nov., Cyclopecten cancellus spec. nov., and one new entoliid, viz. Pectinella aequoris spec. nov. are described. Twelve new records of Pectinacea for this region are mentioned. For Ostrea squamosa Gmelin, 1791 a lectotype is designated. In addition Pectinidae of the... |

Uptake of waterborne Cd, Co, Mn and Zn was determined in laboratory experiments using radiotracer techniques (Cd-109, Co-57, Mn-54 and Zn-65). Labelled Zn was mainly accumulated in the digestive gland (65%) and Co in kidneys (81%); Cd and Mn were similarly distributed in digestive gland and gills. In a complementary field study, Ag, As, Cd, Co, Cr, Cu, Fe, Mn, Ni, and Zn were analysed in scallops collected at two stations showing different contamination levels. Digestive gland and kidneys displayed the highest concentrations. Ag, As, Cd, and Fe differed in soft tissues from the two stations, suggesting that Comptopallium radula could be a valuable local biomonitor species for these elements. Low Mn and Zn concentrations found in kidneys suggest that their... |

An overview is given of the Pectinidae types present in the Gualtieri collection. In Gualtieri (1742) 46 figures (pl. 73 - 15 figs, pl. 74 - 25 figs, pl. 98 – 2 figs, and pl. 99 – 4 figs) show specimens of Pectinidae. Linnaeus (1758) referred to 10 Pectinidae species figured by Gualtieri. Of these, 8 species (7 paralectotypes and one syntype, herein recognised) were traced in the Gualtieri collection, and 2 species (Ostrea peslutrae and Ostrea maxima) were not found. Subsequently, Gmelin (1791) referred to 33 Pectinidae species (12 described by Linnaeus in 1758, one species described by Müller in 1776), and 20 species (13 species were traced, all herein recognised as syntypes, and 7 species were not found) named by himself. No direct evidence was found of... |

El registro más antiguo del género Nodipecten Dall corresponde al Mioceno temprano alto, momento durante el cual tuvo, de acuerdo al registro fosilífero conocido hasta el momento, una distribución discontinua sobre el litoral atlántico occidental, registrándoselo en Patagonia y en la región caribeña. A fines del Mioceno medio se extinguió en Patagonia y desde entonces permaneció restringido a las latitudes tropicales del continente americano hasta hoy, expandiéndose al área tropical del Pacífico oriental en el Mioceno tardío. Su asociación a taxones paratropicales en Patagonia indica el desarrollo de aguas cálido-templadas en la región, reflejando el Óptimo Climático del Neógeno y su extinción en la región y su retracción a latitudes tropicales coincidió... |

Seasonal variations in fatty acid composition in several tissues of a 1-year-old population of giant lion's-paw scallop Nodipecten subnodosus were analyzed during gonad development. Samples were taken bimonthly from December 1999 to June 2000, a period in which gonad development was occurring. Fatty acid accumulation in neutral and polar lipids of the female gonad was concomitant to the gonad development and presented a maximum in June. Among essential fatty acids, a specific accumulation was observed only for 20:5n - 3 in the female gonad, as suggested by an increase in its proportion in the neutral and the polar fractions. However, no specific accumulation was observed for 22:6n - 3, as its proportion remained relatively constant in both fractions. We... |

Fifty-two deep-water species of Pectinoidea (37 Propeamussiidae, 1 Entoliidae, 14 Pectinidae) are listed from Norfolk Ridge (11 species), Loyalty Islands (4 species), Fiji Islands (30 species), Tonga (26 species), Solomon Islands (26 species) and the Marquesas archipelago (8 species). All species from Fiji, Tonga and the Marquesas are new records and six species of Propeamussiidae are new to science: Propeamussium boucheti (Fiji and Tonga), Parvamussium biformatum (Solomons), Parvamussium lozoueti (Fiji and Tonga), Parvamussium marquesanum (Marquesas), Parvamussium polynesianum (Marquesas) and Similipecten herosae (Tonga). Two new combinations (Hyalopecten tydemani, Talochlamys gladysiae) are introduced. |

Twenty-nine species of Pectinoidea (12 Propeamussiidae, 1 Entoliidae, 16 Pectinidae) are recorded from the Austral Islands, the southernmost archipelago of French Polynesia. One genus (Pectinidae: Lamellipecten n. gen.) and five species (Propeamussiidae: Parvamussium australanum n. sp., Cyclochlamys australensis n. sp., Cyclopecten ambiguus n. sp.; Pectinidae: Lamellipecten aduncus n. gen., n. sp., Mimachlamys erycina n. sp.) are new to science, and most others are new records for the archipelago. The near-shore fauna of Rapa has 12 species of Pectinidae, and half of these have narrow-range distributions. Such a remarkably high level of marine endemism is shared by other mollusc taxa on Rapa. |
