Buccinum palssoni sp. nov. is described from deep-water southwest of the central axis of the Reykjanes Ridge and near the northwest margin of the Icelandic shelf in the Denmark Strait. The unique characteristics of this new species are discussed and compared to species that have been considered to belong to the Pacific genus Bathybuccinum Golikov &...
Over a period of 10 years (October 2013 – March 2022) sampling effort was operated by the Fisheries and Benthic scientists of the Marine and Freshwater Research Institute (MFRI) to keep molluscs specimens collected as by-catch when trawling during fish stock assessment around Iceland.
These trawls were primarily made during deep-sea surveys (autumn...
This work reports on 60 marine alien mollusks from nine countries across the Mediterranean Sea and the Sea of Marmara collected by two Belgian citizen scientists. Some of their published observations concerning collection dates are compared with the year of first publication for these alien mollusks reported in the literature, which enable us to ba...
This work reports 60 marine alien molluscs, collected by two Belgian citizen scientists, from nine countries across the Mediterranean Sea and the Sea of Marmara. Some of their published observations concerning the collecting dates are compared with the year of first publication for these alien molluscs reported in the literature, which enabled to b...
Philine angulata Jeffreys, 1867 was found in the digestive tracts of haddocks caught between 69 and 79 m for the first time in NW Iceland, thus adding an additional species to the marine benthic Icelandic fauna. This newly identified presence of the species in Iceland bridges the gap in its distribution between northeast America and the Faroes.
Among molluscs collected at Liman Kalesi (Turkey, Levantine Basin) in 1993 and
2002 and kept in collection, the determination of shells attributed to Lioberus agglutinans (Cantraine, 1835) (Mytilidae) was reviewed. Based on recent bibliographic data these specimens are now reassigned to L. ligneus (Reeve, 1858), an alien species that entered the Me...
Following the description of a new Megastomia Monterosato, 1884 (Gastropoda: Pyramidellidae) from the eastern Mediterranean, we revised the determination of some of our shells kept in collection and attributed them to M. crovatoi Nofroni, Renda & Vannozzi, 2022. Four specimens from Bozcaada (Turkey) were collected alive in shallow water with their...
Despite intensive collections of intertidal material carried out along all coasts of Iceland during the last century, Rissoa parva (da Costa, 1778) failed to be reported in this country. To our knowledge, since then no information concerning the distribution of the species in this part of the world has been published either. Recent samplings showed...
First mention of two Choristella leptalea Bush, 1897 specimens reported alive, side by side, in an empty egg case of elasmobranch (Rajella fyllae Lütken, 1887) in Southwest Iceland at 848 meters depth.

Rapana venosa (Valenciennes, 1846) (Gastropoda, Muricidae, Rapaninae) (WoRMS consultation 2022.02.22) is a gonochoric marine burrowing mollusc, tolerant of brackish waters, predator of bivalves, native to the Sea of Japan and the East China Sea, today becoming invasive in different regions of Europe and the Americas. The story of this great journey...
A specimen of Placiphorella atlantica (Verrill & S.I. Smith, 1882) was collected in the Denmark Strait also called Greenland Strait at a latitude of 64°43'N, the most northerly
position reported to date for this Polyplacophora in the Atlantic Ocean.
Dizoniopsis coppolae (Aradas, 1870) is illustrated from the Bay of Biscay. Ancient
reports of Cerithiopsidae in that area and confusion of names for that species are discussed.
In June 2010, a collaboration between scientists of the Marine and Freshwater Research
Institute (Iceland) and Belgian mollusc specialists was initiated. This collaboration has led to the most extensive registration and sampling of Mollusca around Iceland since the Benthic Invertebrates in Icelandic waters (BIOICE) project (1991-2004). This report...
The Atlantic species assigned to the genus Anomalisipho Dautzenberg & H. Fischer, 1912 are discussed. The status of the genus and the conchological similarities with species assigned to Helicofusus Dall, 1916 and the differences with Plicifusus Dall, 1902 are discussed. Anomalisipho virgata (Friele, 1879) is confirmed as distinct from A. verkruezen...
A late identification of a specimen of Monophorus amicitiae Romani, 2015 collected in March 2000 in the Gulf of Lion (France) allows the extension of the distribution area
of this species. It extends from the southern part of the Tyrrhenian Sea to the Central
Mediterranean Sea via the Tuscan Archipelago.
In 2014, the presence of Aplus assimilis (Reeve, 1846), Pisaniidae from West
Africa, was established for the first time in the Mediterranean Sea. Last year, the discovery of samples from the Tunis Channel (Tunisia) in a private collection revealed that the species was already present in the Mediterranean Sea since at least the 1970s. Such data comi...
Nine species of Raphitomidae belonging to the fauna of Brittany (France) are illustrated and their provenances documented: Cyrillia aequalis (Jeffreys, 1867), C. linearis (Montagu, 1803), Leufroyia concinna (Scacchi, 1836), Raphitoma contigua (Monterosato, 1884), R. cf. echinata (Brocchi, 1814), R. formosa (Jeffreys, 1867), R. oblonga (Jeffreys, 18...

A comparison is made with the paratypes of that species and with specimens of Xylophaga species collected off East Greenland d...
An empty specimen of Manzonia vigoensis (Rolán, 1983) was collected on the north beach of Peniche (Portugal - Costa de Prata) among shell grit during a considerable low tide. This finding in the central part of the Portuguese coastline, together with previous reports of the presence of the species in Galicia and in Algarve allows the establishment...
Five shells of Aporrhais pespelecani occupied by the sipunculan Phascolion strombus collected in Nazaré, Costa de Prata-Portugal were broken. The dissection revealed that they contained, in addition to the siponculan, five specimens of the bivalve Phascoliophila phascolionis. In addition to the bivalve one of the shells contained one specimen of th...
Curveulima dautzenbergi (Gastropoda: Eulimidae) was observed living in association with Antedon bifida (Crinoidea: Antedonidae) during a low tide of great amplitude under rocks of the dike closing the fishing harbour of Tarifa (southern extremity of the Iberian Peninsula - Strait of Gibraltar).
The presence of Curveulima devians (Family Eulimidae - echinoderm parasite of an
unknown host) is well-documented in the Mediterranean Sea. The scarce reports of the presence in the Atlantic date back to the 19th century as coming from material collected in the Canary Islands, Madeira and along the Moroccan coastlines. The species is also quoted in...

The gut content of an irregular sea urchin Spatangus purpureus, collected off the Egadi Islands in Sicily was taken for analysis. This was limited to an inventory of the molluscs present in the sediment ingested by the echinoderm. The analysis showed the presence of 23 species of gastropods, 21 species of bivalves and 1 species of polyplacophoran f...
The presence of two live specimens of Rissoa parva (da
Costa, 1778) in a sample of gastropods collected off Cala Iris
(Mediterranean coast of Morocco) attests that the species
considered by some as exclusively Atlantic is present in the
Mediterranean (Alboran Sea).
Note concerning the presence of Monetaria annulus in the Gulf of Gabes (Tunisia): historical information, reminder of the catch of live molluscs made in the spring of 2006 off the Kerkennah archipelago and off Tripoli by a team from «l’Institut National Agronomique de Tunis et de la faculté des Sciences de Tripoli » and report of the find of an emp...

(Turton, 1825) from the North Atlantic area and Pelseneeria minor Koehler & Vaney,...
Empty shells of Cardium indicum Lamarck, 1819 (Cardiidae) were found in Mahdia harbour (Tunisia). The
presence of the species in Tunisia is discussed.
At Estepona (Spain), an empty shell of Ocenebra erinaceus that had been colonized by Phascolion strombi was found in an octopus trap. The sipunculid had left the shell and consequently a dead specimen of its commensal Montacuta phascolionis was trapped in one of the openings of the shelter of this peanut worm.
Nassarius sesarmus (Marrat, 1877), gastropod of West African origin, was found alive for the first time in the
Algarve - South Portugal. This represents an extension of its distribution towards the North-East Atlantic and the
first record in European waters.
