For this purpose, the material collected from the area between the years 2005 and 2009, within the framework of different projects, was investigated. The investigation of the material taken from various biotopes ranging at depths between 0 and 100 m resulted in identification of 286 mollusc species and 27542 specimens belonging to them. Among the encountered species, Vitreolina cf. perminima (Jeffreys, 1883) is new record for the Turkish molluscan fauna and 18 species are being new records for the Turkish Levantine coast. A checklist of Iskenderun mollusc fauna is given based on the present study and the studies carried out beforehand, and a total of 424 moluscan species are known to be distributed in Iskenderun Bay.

E-mail: [email protected] Abstract Three species in the gastropod genus Calliostoma are confirmed as living in Deep-Water Coral (DWC) habitats in the NE Atlantic Ocean: Calliostoma bullatum (Philippi, 1844), C. maurolici (Seguenza, 1876) and C. leptophyma Dautzenberg & Fischer, 1896. Up to now, C. bullatum was only known as fossil from Early to Mid-Pleistocene outcrops in DWC-related habitats in southern Italy; our study confirmed its living presence in DWC off Mauritania. A discussion is provided on the distribution of DWC-related calliostomatids in the NE Atlantic and the Mediterranean Sea from the Pleistocene to the present. Key words: Mollusca, Calliostoma, deep-water coral associations, NE Atlantic Ocean, Mediterranean Sea, systematics Introduction The Senckenberg Institute and the Royal Netherlands Institute for Sea Research (NIOZ) investigate the geophysi- cal, geological and biological characteristics of scleractinian-dominated Deep-Water Coral (DWC) habitats in the world. -

Therefore, seamounts can only exist where there are sea beds more than one kilo- metre deep, or, which is one and the same thing, over 60%–62% of the land surface1. There are also thousands of smaller elevations that tend to be known as abyssal hills (when they are less than 500 metres) or mounds (between 500 and 1,000 metres). Whether in isolation or as part of extensive ranges, there are possibly more than 100,000 sea- mounts around the world2. At present, close to 30,000 of them have been identified, of which around 1,000 can be found in the Atlantic Ocean3, where in addition the largest range in the world can be found; the Mid–Atlantic Ridge, which stretches from Iceland to the Antarctic. -

Calliostoma conulum, distribution area, Galicia, northwest Spain ABSTRACT. The Galician (NW Spain) population of Calliostoma conulum (Linnaeus, 1758) is analyzed, and it is confirmed that the species is rather common in this area. The geographical distribution of the species is figured. Some différences with the Mediterranean populations are shown and the radula is figured for the first time. INTRODUCTION Parenzan (1970), Nicolay & Angioy (1985), Sabelli, Giannuzzi-Savelli & Bedulli (1990), and represented Calliostoma conulum (Linnaeus, 1758) is mainly in Giannuzzi-Savelli, Pusateri, Palmeri & Ebreo known from the Mediterranean sea. It has been (1994). After Ghisotti & Melone (1971), the species is frequently confused or synonymized with other absent in the Black Sea, but it was recorded on the species. The spécifie name is conulum instead coast of north Africa (Pallary, 1900, 1912) and in the conulus, because stoma is neuter in Greek. Alboran Sea (Salas & Luque, 1986). Pasteur-Humbert (1962) mentions the following distribution: SYSTEMATICS Mediterranean Sea (Spain, France, Italy, Sicily, Corsica, Algeria, Tunis, Adriatic Sea, Egean Sea), The following names are considered as synonyms in Atlantic (Portugal, Madeira, Canary and Azores), and Sabelli étal. (1990): in Morocco up to Casablanca. In the Iberian Peninsula, C. conulum is mentioned in several Trochus lucidum Risso, 1 826 localities of the Mediterranean coast by Hidalgo Trochus violaceum Risso, 1 826 (1917) who also cited it in Portugal, although later Trochus dubium Philippi, 1844 Nobre (1940) did not repeat this record. -
