A new deep water species from of the Chilean coast, Jerrybuccinum kantori sp. n., is described. Te animal is equipped with a large statocyst. Kryptos explorator Fraussen & Sellanes, 2008 from of Concepción is found to be congeneric and transferred to the genus Jerrybuccinum. Diferences in size and sculpture serve to distinguish the new species from J. explorator. Both Chilean species are associated with methane seep or low oxygen environments. Tey are compared with J. malvinense Kantor & Pastorino, 2009 and two still unnamed species from the Falkland Plateau. © Koen Fraussen et al. Source

Buccinidae - like other canivorous and predatory molluscs - are generally considered to be occasional visitors or rare colonizers in deep-sea biogenic habitats. However, casual observations during tropical deep-sea cruises suggest that associations between buccinids and sunken wood, in particular, are not fortuitous. Enigmatocolus monnieri has been found to co-occur in Madagascar with bathymodiolines, vesicomyids and solemyids, indicating the presence of seeps, and species of Thermosipho gen. nov. have been sampled by submersibles and remotely operated vehicles, exclusively from hydrothermal vents. A molecular phylogeny (based on CO1, 12S and 28S genes) reveals that buccinid genera potentially associated with sunken wood (Eosipho, Gaillea gen. nov., Calagrassor gen. nov., and Manaria) are closely related to taxa from vents (Thermosipho gen. nov.) and seeps (Enigmaticolus). The anatomy of several dissected species did not reveal any special trait that could be interpreted as a special adaptation to biogenic substrates. Buccinids from sunken wood are most diverse in the Indo-Pacific centre of marine biodiversity, the 'Coral Triangle', at depths between 100 and 1000 m, with numerous species still undescribed. © Marine Biological Association of the United Kingdom, 2013.

The western Atlantic Ocean members of the genus Engina Gray, 1839, are reviewed. The following taxa are recognized: E. annae new species, E. corinnae Crovo, 1974, E. demani de Jong and Coomans, 1988, E. goncakesi Coltro, 2005, E. itzamnai (Watters, 2009), E. lignea new species, E. pennixta new species, E. turbinella (Kiener, 1836), and E. williamsae new species. Distributional notes are also given for Hesperisternia karinae (Nowell-Usticke, 1959). Source

Eosipho zephyrus, a new deep-water species from off the Chilean coast is described. Protoconch morphology distinguishes the new species from Cantharus aldermaiensis Powell, 1971, a species commonly placed in the genus Eosipho Thiele, 1929. It is the first record of a member of the "Eosipho aldermenensis group" in the eastern Pacific. Generic allocation in Eosipho Thiele, 1929 versus in Manaria Smith, 1906 is briefly discussed. The presence of a third cusp on the lateral teeth of the radula is observed, compared to the same phenomenon in Manaria Smith, 1906 and Colus Röding, 1786, and considered to be an atypical morphology within the group rather than a feature warranting additional taxonomie separation.

During an ongoing research programme to investigate fishing grounds on and around the Rockall Plateau and along the continental slope to the west of Scotland the scientific staff on board of R/V Scotia collected a number of Mollusca as a by-catch, among them several Buccinidae. Two of the larger species deserve more attention: Beringius bogasoni Warén & Smith 2006 and specimens of an unknown Volutopsius. The latter can be distinguished from Volutopsius norwegicus (Gmelin 1791) by the spiral sculpture and is added to the British Fauna as Volutopsius scoriae sp. nov. Source
