The family is divided into four subfamilies. Two new subfamilîes are introduced as Prionovolvinae nov. and Aclyvolvinae nov. The apomorphism and the result of the study of the 16S rRNA gene are contro- versally concerning the Pediculariidae. Therefore, the Pediculariidae are excluded as subfamily from the Ovulidae.

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.

MacGinitie, 1955j was spon- sored by contracts (N6-0NR 243-16) between the OfRce of Naval Research and the California Institute of Technology (1948) and The Johns Hopkins L^niversity (1949-1950).

CNIDARIA Corals, Medusae, Hydroids, Myxozoans
FOUR Phylum CNIDARIA corals, medusae, hydroids, myxozoans STEPHEN D. CAIRNS, LISA-ANN GERSHWIN, FRED J. BROOK, PHILIP PUGH, ELLIOT W. Dawson, OscaR OcaÑA V., WILLEM VERvooRT, GARY WILLIAMS, JEANETTE E. Watson, DENNIS M. OPREsko, PETER SCHUCHERT, P. MICHAEL HINE, DENNIS P. GORDON, HAMISH J. CAMPBELL, ANTHONY J. WRIGHT, JUAN A. SÁNCHEZ, DAPHNE G. FAUTIN his ancient phylum of mostly marine organisms is best known for its contribution to geomorphological features, forming thousands of square Tkilometres of coral reefs in warm tropical waters. Their fossil remains contribute to some limestones. Cnidarians are also significant components of the plankton, where large medusae – popularly called jellyfish – and colonial forms like Portuguese man-of-war and stringy siphonophores prey on other organisms including small fish. Some of these species are justly feared by humans for their stings, which in some cases can be fatal. Certainly, most New Zealanders will have encountered cnidarians when rambling along beaches and fossicking in rock pools where sea anemones and diminutive bushy hydroids abound. In New Zealand’s fiords and in deeper water on seamounts, black corals and branching gorgonians can form veritable trees five metres high or more. In contrast, inland inhabitants of continental landmasses who have never, or rarely, seen an ocean or visited a seashore can hardly be impressed with the Cnidaria as a phylum – freshwater cnidarians are relatively few, restricted to tiny hydras, the branching hydroid Cordylophora, and rare medusae. Worldwide, there are about 10,000 described species, with perhaps half as many again undescribed. All cnidarians have nettle cells known as nematocysts (or cnidae – from the Greek, knide, a nettle), extraordinarily complex structures that are effectively invaginated coiled tubes within a cell. -

High rates of natural mortality, an increase in sea surface temperature, and inability to endure fishing pressure have been mechanisms suggested for the collapse. Fishing using inefficient or non-selective gear not only incurs direct mortality, but can also reduce individual fitness by applying physical damage and physiological stress. Reductions in fitness may compromise yield per recruit or lead to indirect mortality. -
