The stem group from which the Latrogastropoda originated lived during or shortly before Aptian/Albian time (100–125 Ma). Several groups of Latrogastropoda that lived at the time of deposition of the Campanian to Maastrichtian (65–83 Ma) Ripley Formation have no recognized living counterparts. These Late Cretaceous species include the Sarganoidea, with the families Sarganidae, Weeksiidae and Moreidae, which have a rounded and low protoconch with a large embryonic whorl.

Kawili St., Hilo, Hawaii, USA, 96720. E-mail: [email protected] Abstract Species of Parvanachis Radwin, 1968 collected from the Gulf of Panama are anatomically characterized and taxonomi- cally revised. Six species are reported to occur in the region: P. pygmaea (Sowerby, 1832), P. pardalis (Hinds, 1843), P. diminuta (C.B. Adams, 1852), P. albonodosa (Carpenter, 1857), P. milium (Dall, 1916), and P. dalli Bartsch, 1931. Of these six, three are confirmed as described. P. milium was not found in new collections or the previous survey collection and may be more common further south. P. dalli is a synonym of P. pygmaea; and P. albonodosa (auct.) is renamed, be- cause the type material represents a different species. Two new species are described, P. di c h ro m a and P. adamsi. P. parda- lis, based on anatomy and shell and radular morphology, is referred to the genus Anachis, and Costoanachis nigricans (Sowerby, 1844), based on anatomy and shell morphology, is transferred to Parvanachis. The resulting seven species of Parvanachis constitute two groups; one (including the type species) with smaller shells and a simple penis morphology, and a group of four larger species with more complex penis morphology.

Marine mini- and micro-shells from Klong Chao Beach, Koh Kut, Trat province, Eastern Thailand have been investigated between the 3rd -9th of June, 2019. Specimens were randomly collected from the sand sediments in the sandy beach and microhabitat such as under the rock, dead corals, etc in rocky shore by handpicking. A total of 31 families, 57 genera and 66 species were recorded. At least 30 taxa are enlisted as a new record of the Gulf of Thailand. 1.

Y. Low Abstract. An annotated checklist of the Mollusca from the Australian Indian Ocean Territories (IOT) of Christmas Island (Indian Ocean) and the Cocos (Keeling) Islands is presented. The checklist combines data from all previous studies and new material collected during the recent Christmas Island Expeditions organised by the Lee Kong Chian Natural History Museum (formerly the Raffles Museum of Biodiversty Resarch), Singapore. The checklist provides an overview of the diversity of the malacofauna occurring in the Cocos (Keeling) / Christmas Island ecoregion. A total of 1,178 species representing 165 families are documented, with 760 (in 130 families) and 757 (in 126 families) species recorded from Christmas Island and the Cocos (Keeling) Islands, respectively. Forty-five species (or 3.8%) of these species are endemic to the Australian IOT. Fifty-seven molluscan records for this ecoregion are herein published for the first time. We also briefly discuss historical patterns of discovery and endemism in the malacofauna of the Australian IOT. Key words.

Prosobranch Gastropods of Guam
Micronesica 35-36:244-270. 2003 Prosobranch gastropods of Guam BARRY D. SMITH Marine Laboratory University of Guam Mangilao, Guam 96923 U.S.A. email: [email protected] Abstract—Based on records from invertebrate collections at the University of Guam, specimens cataloged at other institutions, and the published literature, there are 895 species of prosobranch gastropods from Guam. The vast majority of the species are marine, but terrestrial and aquatic prosobranchs are included. Most the species recorded to date are conspicuous, epibenthic species from shallow reef habitats, but some species have been taken from depths up to 400 m. Microgastropods less than 7 mm in size have been poorly investigated to date. Comparison of prosobranch gastropods from Guam and Enewetak reveal that some 56% of the species occurring at Enewetak are found in Guam. Introduction Molluscs have been collected in Guam since the arrival of the earliest inhabitants (Thompson, 1945). Despite the long history of European contact with the island, scant attention was given to systematic investigation of the fauna until the collections of Quoy and Gaimard (1824–1826; 1830–1834). Hidalgo (1904– 1905) was the first to produce a catalog that included molluscs from Guam, but his emphasis was mostly on the Philippine Islands fauna. This catalog was followed by a series of unpublished lists produced by shell collectors and shell club members during the last several decades. Synoptic collections of molluscs from Guam and Micronesia were started by faculty of the University of Guam in the mid-1960s. These collections are housed in the Richard E. Dickinson Memorial Mollusc Collection at the University of Guam Marine Laboratory.

Exotic Molluscs in the Mediterranean Basin: Current Status and Perspectives
Oceanography and Marine Biology: an Annual Review 2003, 41, 237–277 © R.N. Gibson and R.J.A. Atkinson, Editors Taylor & Francis EXOTIC MOLLUSCS IN THE MEDITERRANEAN BASIN: CURRENT STATUS AND PERSPECTIVES SERGE GOFAS1 & ARGYRO ZENETOS2 1Departamento de Biologia animal, Facultad de Ciencias – E-29071 Málaga, Spain e-mail: [email protected] 2National Centre for Marine Research, P.O. Box 712, Mavro Lithari, GR-19013 Anavissos, Greece e-mail: [email protected] Abstract An updated synthesis is presented for the records of introduced Mollusca in the Mediterranean basin. The rationale for taking molluscan records as signiﬁcant is discussed. The Mediterranean Sea, with some 1800 native species of Mollusca, currently houses 139 exotic species, of which 85 form established populations, 52 are aliens recorded once or twice, and two are questionable. Ten species (the gastropods Cerithium scabridum, Rhinoclavis kochi, Strom- bus persicus and Bursatella leachi and the bivalves Pinctada radiata and Brachidontes pharao- nis in the eastern Mediterranean, the gastropod Rapana venosa and the bivalves Anadara inaequivalvis, Musculista senhousia, and Xenostrobus securis in the northern Adriatic and the western Mediterranean lagoons) are locally invasive. The bulk of the introduced species (118 species, of which 70 are established, 46 aliens, and two questionable) are species of Indo–Paciﬁc origin found mainly in the eastern basin of the Mediterranean. Among these species, some which live in the Suez Canal are most likely to have spread by their own means through this waterway (these are the “lessepsian immigrants” in the most restricted sense). For other species, the intervention of transport by ship hulls or ballast water can be suspected.

The Black Sea is represented by a total of 20 alien species, the Sea of Marmara by 48 species, the Aegean Sea by 98 species and the Levantine Sea by 202 species. The majority of aliens found in the Black Sea and the Sea of Marmara were transported via shipping, whereas the Levantine coast is extensively subjected to Lessepsian migration. Benthic habitats (soft and hard substrata) comprise 76% of the total alien species and the pelagic environment is inhabited by thirty-nine species. Almost 50% of aliens collected from the Turkish coasts were found only at 0-10 m depth. Eight species occur at depths deeper than 100 m. The impacts of aliens on the benthic and pelagic ecosytems are presented. Keywords: Alien species; Species list; Impact; Black Sea; Sea of Marmara; Aegean Sea; Levantine Sea; Turkey.

The typical form of G. lucia shows an original shell decoration made of continuous wavy axial lines. The distribution of this form seems to be restricted to the northwestern group and to the southern group of the Cape Verde Archipelago. A population showing interrupted axial lines is reported from Boa Vista and it looks as being perfectly similar to populations ranging off the Cap Vert Peninsula (Senegal) and off Fuerteventura (Eastern Canary Archipelago). Due to uncomplete documentation, the precise taxonomic status of this distinctive phena cannot be stated, at present, but despite its fragmented distribution, the concerned populations are united under the provisional term of G. cf. lucia, in the wait of further data.
