Purpose of the present investigation In 1962 the Department of Oceanography, University of Washington, planned to start benthic investigations in the Northeast Pacific Ocean, but as the Depart- ment was inexperienced in the field of benthos research it was felt that a pilot study in Puget Sound would be necessary. The pilot study would be particularly concerned with sampling problems, processing of material, and spatial and sea- sonal variability. Methods and concepts of modern synecology, such as statisti- cal methods for delimiting communities and the concept of species diversity, have received little attention from benthos researchers, and one of the objec- tives therefore has been to test the validity and applicability of some of these methods. It was realized that future studies of the dynamics of productivity and energetics of benthic communities would have to be limited to the dominant spe- cies population. One of the objectives of the present investigation therefore has been to determine which species are the most important and to compile ecologi- cal and biological information about those species. B. Literature review 1. Review of concepts and methods A truly quantitative study of the bottom fauna is a product of this century, and is mainly attributed to the invention of a quantitative sampler, the Petersen grab (PETERSEN and JENSEN 1911). The advantage of grabs over the dredges that had been used in the last century is that they enable the scientist

Sea bottom was found muddy with high similarity in animal community between stations. Animal community found at Eyrarhlíð was predominantly made of common species found in fjord ecosystems in the Westfjords. Polychaetes were the predominant species with Levinsenia gracilis most abundant and good presence of species from the Maldanidae family (Euchone sp. and Galathowenia oculata). Shannon-Wiener diversity index (loge) resulted under 3 for all stations. AMBI classified the site as slightly disturbed. Considering farming was never done in proximity to this site we assume other natural conditions affect the diversity in this area. Visual and chemical parameters did not show any signs of organic impact.

    J. Mar. biol.Ass. U.K. (I954) 33, 457-472 457 Printed in Great Britain A COMPARATIVE STUDY OF THE BRITISH SPECIES OF NUCULA AND NUCULANA By J. A. Allen Zoology Department, The University, Glasgow, and the Marine Station, Millport (Plate I and Text-figs. 1-8) The survey of the sublittoral fauna of the Clyde Sea Area from 1949 onwards has shown that five species of the Protobranchiata are abundant throughout this region on a variety of substrata. Pelseneer (1891, 1899, 1911), Heath (1937), and Yonge (1939) have contributed much to the knowledge of the group as a whole, but little comparative work has been done at species level. Verrill & Bush (1897, 1898) studied the shell characters of the American Atlantic species. Moore (193Ia, b) worked on the faecal pellets of the British Nuculidae and attempted to distinguish the species by this means~ while Winckworth (1930,1931), mainly in the light of the latter work, attempted to clarify the nomenclature of these species. Winckworth (1932) lists six British species of the family Nuculidae: Nucula sulcata Bronn, N. nudeus (Linne), N. hanleyi Winckworth, N. turgida Leckenby & Marshall, N. moorei Winck- 'Worth and N. tenuis (Montagu); and four species of the family Nuculanidae: Nuculana minuta (Muller), Yoldiella lucida (Loven), Y. tomlini Winckworth !lD.dPhaseolus pusillus (Jeffreys). All species of Nucula, except N. hanleyi, were taken from the Clyde Sea Area, although the latter species is included in the Clyde fauna list (Scott Elliot, Laurie & Murdoch, 1901). Only Nuculana minuta of the Nuculanidae has been taken on the present survey. Yoldiella tomlini is included in the 19°1 list but is noted as being' insufficiently attested'.

FEYLING-HANSSEN Department of Micropalaeontology, Geological Institute, University of Aarhus, DK-8000 Aarhus C, Denmark INTRODUCTION Molluscs are an excellent too! in the stratigraphical evaluation of outcrops and cleared seetians where they can be sampied in reasonable quantities, bu t not in thin cores where the y, as other megafossils, are on ly casually and incompletely represented. Molluscs are so rare in the investigated cores that they should only be used with eautian for biostratigraphical purposes in the present stud y. The samples investigated represent half slices of the care. Most of them are 10 cm, same are 20 cm and some are less than 10 cm thick. The dry weight of the samples varies from 20 g to 90 g. Out of 76 examined samples of the Solberga care, only 43 contained fragments or valves of molluscs. The valves are rare and the fragments are usually small. Of 45 examined samples of the Brastad care, 26 contained valves or fragments of molluscs. On the other hand, only 2 of the examined samples of the Moltemyr care were completely barren, but many mollusc fragments of this care were reworked. It has been possible to group the occurring species into four zoogeo­ 12:1 , graphical units (Fig. ) viz. , High-Arctic: these are mainly limited to the present day High-Arctic region; Arctic-Boreal: Arctic species which may also occur in the Boreal region; Boreal-Arctic: Boreal species which may also occur in the Arctic region; Boreal: species which are limited to the Boreal region, or which are Boreal-Lusitanian in their distribution (for definition of these terms see Antevs 1928, p.

ABSTRACT - The present work completes the revision of the Early Pleistocene (Calabrian) protobranchs from the shallow water deposits of Monte Mario and surrounding localities (Rome), present in the Cerulli Irelli collection. Additional material, mostly from the Bellardi & Sacco collection, was also studied in order to clarify the taxonomic status of some poorly known species described in the early literature. Three nuculanid genera are dealt with: Saccella Woodring, 1925, Lembulus Risso, 1826, and Jupiteria Bellardi, 1875. The Plio-Pleistocene species of Saccella have been often confused as a single, notably variable species, usually reported as Nuculana fragilis (Chemnitz, 1784) or N. commutata (Philippi, 1844). Four species of Saccella occurred in the Mediterranean Plio-Pleistocene: S. commutata (Philippi, 1844), S. consanguinea (Bellardi, 1875), S. bonellii (Bellardi, 1875) and S. calatabianensis (Seguenza, 1877). Of these, S. commutata and S. calatabianensis were present in the Early Pleistocene. Other Plio-Pleistocene species of Saccella are expected, basing on literature data and on available material. Lembulus included a single Plio-Pleistocene and extant species, L. pella (Linné, 1758). Jupiteria occurred in the Plio-Pleistocene with a single shallow water species, J. fissistriata (Foresti, 1897 ex Meneghini ms), but two other deep-water species are known: J.
