The Society was registered as a Charity in 1978 (Registration No. 275980) with the Rules which were adopted on 17 May 1978. The objects of the Society are to advance education, research and learning for the public benefit in the study of the Mollusca from both pure and applied aspects. Meetings are held throughout the year. The Annual General Meeting is held in March. Membership is open to all individuals who are interested in the study of molluscs. The annual subscription for 1982 for Private members is £12.00 or S31.20 U.S. & Can.; for Student members £5.00 or $13.00; for Institutional/Library members is £25.00 or $66.60, due on January. Remittances should be drawn in in favour of 'The Malacological Society of London' and sent to the Hon. Secretary with applications or to the Hon. Treasurer with renewals. No receipt will be sent for payments by cheque on members' own accounts at either United Kingdom or United States banks, unless specially requested. Members with accounts at British banks are urged to pay by Standing Order; forms are available from the Hon. Treasurer, United States and Canadian members may pay by Standing Order; forms are available from the Hon. Treasurer. United States and Canadian members may pay by personal cheque. The dollar subscription rates take into account postage and the charges made by the Society's bank for processing foreign cheques. Members are entitled to receive a copy of The Journal of Molluscan Studies, to attend the meetings of the Society, to vote in the election of Council and Officers and are eligible for election to Council and Office. The Journal is issued three times a year, a volume consisting of three parts. The price of a single issue is £10 ($26.00). The annual subscription for non-members is £25.00 ($66.60) post free. Back numbers may be purchased on application to the Editor, but complete series are no longer available. In 1976 the Society started publishing a series of Supplements to the Journal which are available to members at a reduced rate. Orders for Supplements should be sent to: Angus Graham Associates, 70-78 Queen's Road, Reading, RG1 4BP. An Annual Award was also instituted in 1976. The award is given to a person who, in the opinion of the Society's adjudicators, has made an exceptionally promising initial contribution of the study of molluscs. Nominations from any member of the Society must reach the Hon. Secretary by 31 October each year. The Radley Library is available for study in the separate Library for Biological Sciences, Foster Court Building (first floor), University College, London.

  • Reconnaître Les Principaux Bivalves Fouisseurs Ou Foreurs Au Moyen De Leurs Siphons
    Reconnaître les principaux bivalves fouisseurs ou foreurs au moyen de leurs siphons. 56 espèces Clé de détermination des 20 taxons les plus gros Yves MÜLLER Yves Müller Mai 2016 Reconnaître les principaux bivalves fouisseurs ou foreurs au moyen de leurs siphons. Dans la quasi-totalité des ouvrages traitant des mollusques lamellibranches (ou mollusques bivalves), ce sont les coquilles qui sont décrites (la conchyologie) avec principalement la description des charnières pour la classification. Pour les parties molles (la malacologie) ce sont les branchies qui sont utilisées. Ce qui n’est pas très accessible au plongeur même photographe ! Selon Martoja (1995) 75 % des espèces de bivalves vivent dans les fonds meubles. Certaines espèces trahissent leur présence par leurs siphons qui affleurent à la surface du sédiment, mais il est difficile, au cours d’une plongée, d’identifier les bivalves enfouis dans le sédiment. D’autres espèces de bivalves vivent dans des substrats durs (bois, roche). Ils forent alors une loge dans ce substrat et en général seuls les siphons sont visibles. Le même problème se pose, à quelle espèce appartiennent les siphons ? Selon Bouchet et al. (1978 :92): « Les siphons constituent un moyen de détermination des bivalves aussi fiable que la coquille et la charnière ». Des auteurs anciens comme Deshayes (1844-1848), Forbes et Hanley (1850-1853), Jeffreys (1863, 1865) et Meyer & Möbius (1872) et quelques autres plus récents comme Owen (1953 ; 1959), Purchon (1955a, b), Holme (1959) et Amouroux (1980) ont décrit les siphons de plusieurs espèces. La plupart des espèces de bivalves mesurent entre un et plusieurs centimètres mais les siphons sont pour la plupart courts ou très fins et rétractiles au moindre danger, donc difficilement observables en plongée.

    Intersex in the clam Scrobicularia plana (Da Costa): Widespread occurrence in English Channel estuaries and surrounding areas. N D Pope1*, K Childs1, C.

Tel.: +44 1752 633272; fax: +44 1752 633102 E-mail address: [email protected] Abstract Estuarine clams Scrobicularia plana were sampled from 108 intertidal locations around the English Channel and adjacent areas. Although S. plana is believed to be a strict gonochorist, 58% of the populations sampled included intersexed individuals (described as male clams exhibiting ovotestis). Over the entire region, on average, 8.6% of male clams exhibited intersex, although proportions of affected males ranged from 0% to 53% depending on location. The severity of intersex was assessed using a simple classification scale, with the majority of individuals showing low levels of impact. Sex ratios were significantly skewed at some sites. There were no significant relationships between the incidence and severity of intersex; or of associations with size or parasitism of individual clams. Intersex in S. plana is a useful tool to assess endocrine disruptive effects in estuaries, although mechanisms of impact and causative agents remain uncertain. Keywords: Intersex, endocrine disruption, Scrobicularia plana, sex ratio, English Channel 1. Introduction Intersex In gonochoristic (dioecious) organisms, intersex is defined as the abnormal condition of being intermediate between male and female sexes, a hermaphrodite.

  • Pursuing the Quest for Better Understanding the Taxonomic Distribution of the System of Doubly Uniparental Inheritance of Mtdna
    Pursuing the quest for better understanding the taxonomic distribution of the system of doubly uniparental inheritance of mtDNA Arthur Gusman1, Sophia Lecomte2, Donald T. Stewart3, Marco Passamonti4 and Sophie Breton1 1 Department of Biological Sciences, Université de Montréal, Montréal, Québec, Canada 2 Department of Biological Sciences, Université de Strasbourg, Strasbourg, France 3 Department of Biology, Acadia University, Wolfville, Nova Scotia, Canada 4 Department of Biological Geological and Environmental Sciences, University of Bologna, Bologna, Italy ABSTRACT There is only one exception to strict maternal inheritance of mitochondrial DNA (mtDNA) in the animal kingdom: a system named doubly uniparental inheritance (DUI), which is found in several bivalve species. Why and how such a radically different system of mitochondrial transmission evolved in bivalve remains obscure. Obtaining a more complete taxonomic distribution of DUI in the Bivalvia may help to better understand its origin and function. In this study we provide evidence for the presence of sex-linked heteroplasmy (thus the possible presence of DUI) in two bivalve species, i.e., the nuculanoid Yoldia hyperborea (Gould, 1841) and the veneroid Scrobicularia plana (Da Costa, 1778), increasing the number of families in which DUI has been found by two. An update on the taxonomic distribution of DUI in the Bivalvia is also presented.

  • Does Polyxenous Symbiosis Promote Sympatric Divergence? a Morphometric and Phylogeographic Approach Based on Oxydromus Okupa (Annelida, Polychaeta, Hesionidae)

We analyse these populations morphometrically, ecologically (including infestation characteristics) and genetically (intertidal popula- tions, 16S and ITS-1 genes). We consider “host”, “environment” and the combined “host and environment” as possible factors of interpopulation variability. Morphometry revealed three well-defined clusters for CI, CH and CS, showing intergroup phenotypic differences ranging from 35 to 50%. Hosts shell lengths ranged between 26 and 36 mm for S. plana and 20 and 28 mm for M. pellucida. The infestation of small M. pellucida by juvenile O. okupa suggests they show an active size segregation behaviour. The intertidal seems to be less favourable (infestation rate <25% vs. up to 65% in the subtidal), and did not show recent bottleneck events.
