A New Species

Collections of bottom-living animals from the continental slope of the northern Bay of Biscay contain a new species of Oligobrachia; this increases the number of species of Oligobrachia known from the North Atlantic to five. Oligobrachiids are quite frequently found incubating embryos and five individuals of the new species carry embryos. Oligobrachia embryos have been studied morphologically already (Ivanov, 1957, 1975; Southward & Southward, 1963; Brattegard, 1966; Ivanov & Gureeva, 1976) and should prove useful material for experimental studies in future. Incubation is also known in the family Siboglinidae, but neither embryos nor larvae have been seen in any other pogonophoran families. The Biscay collections also contain additional specimens of Oligobrachia ivanovi and these have been useful in revising the description of this rather rare species.

A New Species

The first species ofLamellisabella to be described from the Atlantic Ocean has rows of small teeth on the tentacles. It occurs at about 4000 m depth in the Bay of Biscay, and its range probably extends along the continental rise at least as far south as the Gulf of Guinea.

A New Species

A new species of hydroid, Candelabrum fritchmanii, is described from Cape Arago, Oregon, U.S.A. Specimens were collected from the intertidal region underneath boulders. This new species' standing with respect to other members of the genus is discussed. The claspers in the blastostylar region of the new species show similarities to the North Atlantic Candelabrum cocksii. However, three specimens had multiple, connected polyps at varying stages of development and the cnidome differs between C. cocksii and the new species, leading to the erection of a new species. The polyp cnidome consists of desmonemes, heteronemes (microbasic mastigophores and homotrichous microbasic euryteles), and stenoteles and the actinula cnidome consists of desmonemes, haplonemes (atrichous isorhizas), and stenoteles. Emendations to the family, subfamily, and genus diagnoses are presented to accommodate these findings. Observations are also presented on actinula development and the ensnaring, predatory feeding behavior of the highly contractile polyp.

A New Species

The genus Desmoxya Hallmann, 1917, erected for south-east Australian Higginsia lunata Carter, 1885, was assigned to the synonymy of Higginsia Higgin, 1877 (Porifera: Halichondrida) by the latest revision of the taxonomy of the Porifera (Hooper & van Soest, 2002). The discovery of an undescribed species living in the bathyal reefs of the North Atlantic Rockall Bank with characters closely similar to H. lunata justifies the resurrection of Desmoxya. Accordingly the North Atlantic material is described as a new species in Desmoxya, viz. D. pelagiae sp. nov. The new species differs from its Australian congener in habit (smooth thin crusts vs massive with digitiform processes) and spicule sizes (smaller megascleres, twice-sized acanthoxeas and single vs two sizes of trichodragmas). A probable third member of this genus is Higginsia anfractuosa Hooper & Lévi, 1993, described from shallow-water reefs near New Caledonia. For reasons of priority the name of the family to which Higginsia and Desmoxya are assigned needs to be changed from Desmoxyidae Hallmann, 1917 to Heteroxyidae Dendy, 1905, as this senior synonym was overlooked when Heteroxya was assigned to the same family as Higginsia and Desmoxya in Hooper & van Soest, 2002.

A New Species

A new species of Polyplacophora (Mollusca) has been found in the Salice outcrop, in the Peloritain Mountains (Sicily, Italy), is attributed to the early Pleistocene. Lepidopleurus (Leptochiton) salicensis n.sp. is characterized by its uniformly sculptured tegmentum, with (well) raised, randomly distributed, neatly separated rounded/polygonal granules. The new species is compared with Lepidopleurus (Leptochiton) alveolus (M.Sars MS, Lovén, 1846), from the North Atlantic, and Lepidopleurus (Leptochiton) tavianii Dell’Angelo, Landau & Marquet, 2004, from the Pliocene of Estepona (Málaga, Spain).

A New Species

A new species of Ophlitaspongia (Porifera: Microcionidae) from wave-exposed sublittoral rock in the north-east Atlantic is described and compared to the two other species recorded from the genus in the north-east Atlantic. The species known as Ophlitaspongia seriata is considered to be a junior synonym of Halichondria panicea. Consequently, the name O. papilla has been reinstated. The other recorded species O. basifixa, is from deep water. Ophlitaspongia basifixa has characters which differentiate it from Ophlitaspongia sp. nov. The genus Ophlitaspongia has been separated from related genera and reinstated for species in the North Atlantic.

A new cirratulid species of the genus Chaetozone has been discovered offshore in fine muddy sediments in the Bay of Biscay, France. This species is unusual in having an expanded fusiform anterior body region and numerous subdermal glands along the entire body that produce an elaborate and distinctive pattern when stained with Methyl Green. The new species is compared with closely related congeners and a review of Chaetozone species from the North Atlantic Ocean is presented.
