| Tonnoidean gastropods in K. Martin’s and other collections in the Nationaal Natuurhistorisch Museum, Leiden (and a few other minor collections) are reidentified and classified. The resulting fauna of 99 species is very similar to that of the Indo-West Pacific today, 70% of species still inhabiting the Indonesian region. Species endemic to the Miocene and Pliocene rocks of Indonesia are Bursa sangirana sp. nov., and two new (unnamed) species similar to Bursina ignobilis (Beu); Cassis depressior Martin and C. preangerensis Martin; Cypraecassis denseplicata (Martin) and an unnamed species of Cypraecassis; Sconsia martini van Regteren Altena and S. pulchra Pannekoek; Echinophoria vandervlerki Martin (possibly a synonym of E. wyvillei (Watson)); Phalium... |

| A borehole was drilled at Rotterdam in 1955 as a demonstration during the E55 exhibition. Holoplanktonic molluscs (pteropods) were found to be present in the interval 504.5-655.0 m below rotary table (= RT). The upper sample of Middle Eocene (Lutetian) age yielded just a few unidentifiable limacinids. The section between 507.5-607.0 m, of Early Eocene (Ypresian) age, yielded poorly preserved pteropods and demonstrated that the complete interval belongs to pteropod zone 9. Apart from the most abundant species, Camptoceratops priscus, which is the index taxon of pteropod zone 9, the section yielded Heliconoides mercinensis and Limacina taylori, which are known to accompany the index species. Two further limacinid species are described as new to science, viz.... |

| The goal of this study is to assess if the reproductive strategy of a brooding land snail shifts along a climatic gradient. We focused on the following traits: timing and length of the reproductive season, brood size, ontogenetic dynamics of embryos, and reproductive mode (viviparity versus egg-laying). We dissected the central European door snail Alinda biplicata, collected monthly from eight populations covering the oceaniccontinental climatic gradient within the species’ distribution range. Forty percent of the 1706 dissected individuals were brooding. The species displayed a spring-summer reproductive activity pattern: intrauterine brooding was recorded between March and September; first embryos of a developmental stage that equals that of live-born... |

| The 1990 Rumphius Biohistorical Expedition to Ambon (Indonesia) made 44 collecting stations. Twenty-seven species representing 11 genera of the Naticidae (Gastropoda: Caenogastropoda) were collected at 29 stations. This paper provides keys to the genera and species, along with diagnoses and short synonymies of the species. The modern identity of the thirteen naticid species known to Rumphius in his “D’Amboinsche Rariteitkamer” (1705) is determined. Fifty described species of Naticidae are currently known from Malaysia and Indonesia, with 38 known from Ambon itself (this expedition and older museum collections). |

| The present work revises the taxonomy of one group of camaenid gastropods from Timor-Leste based on the study of a large number of recently collected ethanol preserved samples as well as historic museum material, including types. By employing comparative analyses of the variation in morphological features (shell, penial anatomy) and the differentiation in mitochondrial DNA sequences of the cytochrome c oxidase subunit 1 gene (COI) and the 16S rDNA (16S), altogether nineteen species are recognized from Timor-Leste and adjacent areas in the Lesser Sunda and Moluccas, such as West-Timor, Adonara, Leti and Sermata Islands (Indonesia). Four of these species were described previously and have mostly been placed within the genus Chloritis Beck, 1837 in the few... |

| On the basis of both detailed distributional field studies and morphological analyses, a revision of the polytypic species Albinaria hippolyti from Central and Eastern Crete is presented. True subspecies are distinguished from mere geographic varieties by the presence of narrow hybrid zones. Using this criterion, four adjoining subspecies are recognised: A. h. hippolyti (Boettger, 1878), A. h. aphrodite (Boettger, 1883), A. h. holtzi (Sturany, 1904) and A. h. harmonia subspec. nov. Additionally, two geographically isolated and conchologically distinctive forms are also treated as subspecies: A. h. arthuriana (Boettger, 1878) and A. h. asterousea subspec. nov. The geographical distribution and variability of each subspecies is described in detail. A. h.... |

| This report deals with the species of Muricidae collected during the Rumphius Biohistorical Expedition on Ambon. At 44 stations, a total of 58 species in 23 genera of the prosobranch gastropod family Muricidae were obtained. The identity and the classification of several nominal taxa is revised. Four species are new to science and are described here: Pygmaepterys cracentis spec. nov. (Muricopsinae), Pascula ambonensis spec. nov. (Ergalataxinae), Thais hadrolineae spec. nov. and Morula rumphiusi spec. nov. (Rapaninae). Some comments are included on the Muricidae described by Rumphius and on their identification. In his "Amboinsche Rariteitkamer" (1705) 21 species of muricids were included, of which 16 were illustrated by Rumphius or Schijnvoet. The identity... |
