abstract Tsunamis have been reported from widely distributed locales with the area under consideration. They seem to be more common in the Azores and the Iberian peninsula than elsewhere. This may result partly from the lack of, or inavailability of data rather than the absence of the phenomena.

Four uncommon bathyal thecate hydroids, Plicatotheca anitae Calder & Vervoort, 1986, Zygophylax africana Stechow,1923, Nemertesia falcicula (Ramil & Vervoort, 1992a) and Pseudoplumaria marocana (Billard, 1930), were collectedduring benthic surveys of the Cantabrian Sea and the Galicia Bank (Spain, northeastern Atlantic). Northern ranges of allfour are extended in the Atlantic Ocean. Elsewhere in the northeastern Atlantic, Plicatotheca anitae is known only fromthe Azores, while the nearest records of Nemertesia falcicula and Pseudoplumaria marocana are the Strait of Gibraltarand from a station northwest off Cape San Vicente in the south of Portugal, respectively. Zygophylax africana, known onlyfrom South Africa and Japan, is new to the European fauna and was obtained at an unusual depth. Each of the four species is described and illustrated, and their distributions and bathymetric ranges are revised.

AbstractFrom the Triassic to the Late Eocene, the Iberian Peninsula underwent three successive rotations with respect to the stable European plate, (a) Prior to the Late Aptian, a nearly 150 km southwestward motion resulted in stretching and thinning of the continental crust beneath the North Pyrenean zone, the Aquitaine Basin and the Bay of Biscay continental margins (rifting). Distensive structures trended 90° N to 130° N, and were shifted by 30° N to 50° N transform faults. (b) During the Late Aptian to Santonian interval, an approximately 400 km southeastward motion resulted in the opening of the Bay of Biscay and sinistral slipping of Iberia along the North Pyrenean transform zone (drifting), (c) During palaeocene–Eocene time, a 150 km northwestward convergent motion resulted in limited subduction of the oceanic crust of the Bay of Biscay beneath the Iberian plate, and folding of the Pyrenean chain. The folded belt resulted from squeezing of the former European and Iberian margins (rifted or transform margins, depending on the segment considered).

Abstract The occurrence of the flexed verticord, Halicardia flexuosa (Verrill & S. Smith [in Verrill], 1881), is reported for the first time from the Bay of Biscay (North Iberian Peninsula). This rare bivalve was collected from deep waters (1200 m depth) of the Avilés Canyon Systems (Central Cantabrian Sea). We provide a detailed description and illustration of the species, as well as brief notes on its ecology at the new locality and its global biogeography.

Resumen Una especie nueva del género Streblospio Webster, 1879 (Annelida, Spionidae) ha sido identificada en el sureste del golfo de Vizcaya. La nueva especie, Streblospio eunateae sp. nov., ha sido recolectada entre los años 2013 y 2018 en sedimentos fangosos intermareales y submareales de las provincias de Gipuzkoa y Bizkaia (NE de la península Ibérica). Se realiza una descripción, ilustración y discusión de la misma, aportándose también información sobre su ecología y distribución. Complementariamente, se aporta una clave de identificación de todas las especies conocidas de Streblospio. Abstract A new species of the genus Streblospio Webster, 1879 (Annelida, Spionidae) has been identified from SE Bay of Biscay. The new species, Streblospio eunateae sp. nov., has been collected between 2013 and 2018 in intertidal and sub-littoral muddy sediments from Gipuzkoa and Bizkaia (NE Iberian Peninsula). The species is described, illustrated and discussed. Some notes on its ecology and distribution in the area is also included. In addition, an identification key is provided for all known Streblospio species.
