“…It is possible there is a special relationship between the two species although I have no evidence for this. There is a parallel association dominated by the echiuroid Listriolobus pelodes off the south Californian coast (Jones, 1964) in which the characteristic mollusc is Saxicavella pacifica. With this association is grouped for convenience the Modiolus epifauna association, which scarcely occurred in the anchor-dredge samples, but which may be present locally around the Channel Islands, and the dense beds of Ophiothrix fragilis, with Ophiocomina nigra present in some places, which occur as epifauna on some stony or rocky grounds (cp.…”

An earlier paper (Holme, 1961) described the bottom fauna off the south coast of England, as sampled by a modified anchor-dredge. Sampling was later extended to cover the whole English Channel, a further 144 stations being worked, making 311 in all. This paper describes the results of the later survey which, as previously, was concerned mainly with molluscs and echinoderms. Distribution charts for the majority of species identified are given, in which are incorporated the results of both surveys.

Abstract, ddontorhiua cyclin BERRY, 1947 is widely distributed on the continental borderland of southern California. It is a fannal element I n every major habitat type including two of the outer deep basins, Santa Cruz Basin and 8an Nicolas Basin. On the mainland shelf it is discontinuously distributed from Point Conception to the USDiexican Border. The depth distribution of Adonforhincc reflects the fact that it inhahits both topographic highs and some of the deep basins of the tmrderland. Tts depth range is from 11.6 to 1,886.0 meters. While rldonforhina is able to inhabit H N ide range of sediment types, from 1.5 to 8.1 mean phi, it was primarily collect.ed from locations n here sediments ranged from 3 to 5 mean phi. A direrse array of macrofaunal taxa is associated with ddontorhina. The nrimerically dominant t a m varied from habitat to habitat.

A minute bivalve, Adontorhina keegani, new species (Thyasiridae) is described from the Porcupine Bank, west of Ireland. The new species occurs between 300 and 789 m on the continental slope. The shell is elongate and compressed, with a flattened posterior and complete lack of radial sulcus. The shell has a hinge margin bearing irregular granules and noticeably low umbones, located in the posterior. Hydroids were found growing on the margins of the shell, indicating a shallow burrowing habit. Adontorhina similis, new species, was previously recognized as a European variety of Mendicula pygmaea Verrill & Bush, 1898, but is here shown to be a distinct species. The hinge bears irregular granules, which precludes classification as a Mendicula species. The shell is elongate, moderately inflated with prominent umbones and a pointed posterior margin. The posterior flank of the shell is flattened and does not bear hydroids. In comparison with previously described species of Adontorhina, the new species are more elongate and less inflated.
