In the course of dredging for the rich epifauna of the continental slope near 48° 30′N., 10° W. (Southward & Southward, 1958b) in May 1957, several hauls were made by chance on a muddy bottom at 500–700 fin. depth. At the time, these hauls were examined only cursorily after sieving, and the con-tents immediately preserved. One of the hauls contained several damaged siliceous sponges, and a recent careful examination disclosed a number of pogonophore tubes entangled among the threads and spicules of the sponges.

Two New Species

The aim of this study is to solve taxonomic problems pertaining to Spio filicornis (O.F. Müller, 1776). The original description by O. F. Müller was very brief and type material was not deposited. Based on the literature the confusion about the identity of the species has been tremendous; e.g., it was only recently realized that at least two different species from the North and Baltic Seas could be identified as S. filicornis (Bick et al. 2010). The present study is based on material collected by the authors in 2009 at the type locality in Iluilârssuk, near Paamiut, SW Greenland. Spio filicornis is redescribed in detail and illustrated comprehensively. A neotype has been designated and deposited in the collection of Rostock University. Species formerly referred to as S. cf. filicornis from the North and Baltic Seas (Bick et al. 2010) are formally described as two new species, Spio arndti sp. nov., and S. symphyta sp. nov. The morphological diagnostic characters within Spio are discussed. Information on three molecular markers (16S rDNA, 18S rDNA, cytochrome c oxidase subunit I) is also provided. The genetic divergence between the three Spio species corroborates the taxonomic discrimination.

Two New Species

In May 1958 it was thought that all species of Pogonophora so far discovered in the north-east Atlantic belonged to the genusSiboglinumCaullery (Southward & Southward, 1958). Since then I have had the opportunity of examining further collections from deep water off the British Isles and Spain. At least two species of multitentaculate pogonophores have been discovered, and re-examination of some material collected in May 1958 shows that one of the species was also present in these collections. Although considerable material belonging to other species remains to be worked up it has been thought worth while to describe these two species first. One is widespread and can be locally abundant, while the other is the largest pogonophote so far found in the Atlantic. Both are the first Atlantic representatives of their respective genera.

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.
