New Records of the Rare Gastropods Erato Voluta and Simnia Patula, and First Record of Simnia Hiscocki from Norway
Fauna norvegica 2017 Vol. 37: 20-24. Short communication New records of the rare gastropods Erato voluta and Simnia patula, and first record of Simnia hiscocki from Norway Jon-Arne Sneli1 and Torkild Bakken2 Sneli J-A, and Bakken T. 2017. New records of the rare gastropods Erato voluta and Simnia patula, and first record of Simnia hiscocki from Norway. Fauna norvegica 37: 20-24. New records of rare gastropod species are reported. A live specimen of Erato voluta (Gastropoda: Triviidae), a species considered to have a far more southern distribution, has been found from outside the Trondheimsfjord. The specimen was sampled from a gravel habitat with Modiolus shells at 49–94 m depth, and was found among compound ascidians, its typical food resource. Live specimens of Simnia patula (Caenogastropoda: Ovulidae) have during the later years repeatedly been observed on locations on the coast of central Norway, which is documented by in situ observations. In Egersund on the southwest coast of Norway a specimen of Simnia hiscocki was in March 2017 observed for the first time from Norwegian waters, a species earlier only found on the south-west coast of England. Also this was documented by pictures and in situ observations. The specimen of Simnia hiscocki was for the first time found on the octocoral Swiftia pallida. doi: 10.5324/fn.v37i0.2160.

Belgium. SUMMARY: The gastropod family Hipponicidae comprises widely distributed but poorly known sedentary species. On the beach-rock of the coral reefs of Laing Island (Papua New Guinea) live rich populations of several gastropod Turbo species of which many specimens have attached to their shell a hipponicid gastropod attributed to a new species, Antisabia juliae. This new species, described in this paper, appears to have adapted its mode of life on live turbinids in several ways result- ing in morphological changes (thin basal plate loosely adherent to the supporting shell, functional eyes, very long snout, functional radula, small osphradium) and ethological changes (foraging behaviour: it appears to feed on the epiphytic com- munity growing on the host, in the vicinity of the “host” shell). Except for these characteristics, the mode of life appears quite similar to that of other hipponicid species with few big females surrounded by several much smaller males. Development occurs within the egg mass inside the female shell and a few young snails escape at the crawling stage. Key words: Mollusca, Gastropoda, ecology, Hipponicidae, Papua New Guinea, Indopacific. RESUMEN: BIOLOGÍA Y DESCRIPCIÓN DE ANTISABIA JULIAE SP.

INTRODUCTION The genus Doriopsilla (family Dendrodorididae) was established by Bergh (1880) and the type species, Doriopsilla areolata, was described from the MediterraneanSea. Further known from Doriopsilla species are different seas (Alder & Hancock, 1864; D'Oliveira, 1895; Baba, 1949; Marcus, 1961; Burn, 1962, 1989; Marcus & Marcus, 1967; Edmunds, 1968; Meyer, 1977; Valdes & Behrens, 1998; Gosliner, Schaefer & Millen, 1999, etc.). Some ascribed Dendrodoris Doriopsilla species were to (Allan, 1933; Pruvot-Fol, 1951, 1954; Behrens, 1980, 1991; McDonald & Nybakken, 1981; McDonald, 1983; Baba, 1933, since 1949) the two are similar. the was genera superficially Recently genus Doriopsilla reviewed Valdes but (Valdes, 1996; & Ortea, 1997) the numberof valid species is uncer- tain. Four species are known from South Africa (Bergh, 1907; Gosliner, 1987) and only of these named.

ABSTRACT Title of Dissertation: PATTERNS IN
ABSTRACT Title of Dissertation: PATTERNS IN DIVERSITY AND DISTRIBUTION OF BENTHIC MOLLUSCS ALONG A DEPTH GRADIENT IN THE BAHAMAS Michael Joseph Dowgiallo, Doctor of Philosophy, 2004 Dissertation directed by: Professor Marjorie L. Reaka-Kudla Department of Biology, UMCP Species richness and abundance of benthic bivalve and gastropod molluscs was determined over a depth gradient of 5 - 244 m at Lee Stocking Island, Bahamas by deploying replicate benthic collectors at five sites at 5 m, 14 m, 46 m, 153 m, and 244 m for six months beginning in December 1993. A total of 773 individual molluscs comprising at least 72 taxa were retrieved from the collectors. Analysis of the molluscan fauna that colonized the collectors showed overwhelmingly higher abundance and diversity at the 5 m, 14 m, and 46 m sites as compared to the deeper sites at 153 m and 244 m. Irradiance, temperature, and habitat heterogeneity all declined with depth, coincident with declines in the abundance and diversity of the molluscs. Herbivorous modes of feeding predominated (52%) and carnivorous modes of feeding were common (44%) over the range of depths studied at Lee Stocking Island, but mode of feeding did not change significantly over depth. One bivalve and one gastropod species showed a significant decline in body size with increasing depth. Analysis of data for 960 species of gastropod molluscs from the Western Atlantic Gastropod Database of the Academy of Natural Sciences (ANS) that have ranges including the Bahamas showed a positive correlation between body size of species of gastropods and their geographic ranges. There was also a positive correlation between depth range and the size of the geographic range. -

Shelling on Sint-Maarten/Saint Martin, the ‘Friendly Island ’: Part I: Introduction and Land Mollusca
Shelling on Sint-Maarten/Saint Martin, the ‘Friendly Island ’: Part I: Introduction and land mollusca Delphine Clement, Patricia Nolf & Frank Nolf 1 1 Pr. Stefanieplein 43 B8 B-8400 Oostende [email protected] Neptunea, vol.14, n°1 1 May 2016 1 Introduction Geography Sint-Maarten/Saint Martin (SXM) is situated at 18°04' N, 63°04′ W and belongs to what is called the 'Windward Islands', together with Puerto Rico, Saba, the Virgin Islands and some other islands, in contrast to the 'Leeward Islands' Aruba, Curaçao and Bonaire north of Venezuela. Saint Martin is confined by the Atlantic Ocean in the north and by the Caribbean Sea in the south. Saint Martin belongs to the northernmost islands of the Lesser Antilles in the external volcanic arc. It consists of two parts: the French Saint-Martin in the north and the Dutch Saint Maarten in the south. The total area is 86 km², of which about 34 km² is inhabited by approximately 35,000 of people in the Dutch Saint Martin. The ‘Collectivité de Saint Martin’, is an overseas collectivity of France and has an area of about 53 km², inhabited by more than 32,000 inhabitants. The capital of the Dutch part is Philipsburg while Marigot is the French capital. The island is very hilly and is dominated by several 'Hills' or 'Monts' such as the Mt. France, Mt. Boeuf, Mt. Caretta, Sentry Hill and above all the highest hill, the Pic Paradis (424 m). Ridges of the hills run into the sea and with a certain regularity around the coastline which is interrupted by numerous bays and white beaches, where hundreds of hotels and resorts shoot up like mushrooms. -
