SONMAIRE Le repertoire est une liste en ordre alphabetique des taxons dino- kystes fossiles au rang generique et sous ce rang, incluant ceux signales par les auteurs au 1 avril 1981; it comprend 413 genres, 2210 espaces, 230 sous-espaces, et 2 varietes. On y trouve aussi 73 noms generiques, qui ne sont plus juges valides. On propose 117 nouvelles combinaisons, ainsi que 12 nouveaux noms pour les homonymes de rang inferieur et 9 changements de rang. On renvoie les nouvelles combinaisons au "basonyme" et aux autres combinaisons. Tous les articles mentionnes dans le texte sont inscrits dans la bibliographie. ZZi INTRODUCTION The number of taxonomic papers on dinoflagellates has increased dramati- cally since the appearance of the last index, Lentin and Williams, 1977b. That publication represented an update of the first index of dinoflagellate genera and species, Lentin and Williams, 1973, which listed 292 genera and 1328 species. In the second edition, the number of taxa had risen to 342 genera and 1700 species. Now, a mere four years later, the latest index includes details on 413 genera, plus 73 no longer considered legitimate, and 2210 species. This update attempts to provide a current listing of all dinoflagellate cyst genera and species included in publications available to the authors as of April 1st, 1981. Although most of the taxa listed are fossil, we have included a few Recent dinoflagellates whose equivalent motile stage is unknown or uncertain. Dinoflagellates have been described both as animals, necessitating their classification under the International Code of Zoological Nomenclature (I.C.Z.N.), and as plants which are subject to the International Code of Botanical Nomen- clature (I.C.B.N.). Since a preponderance of species are autotrophic (synthe- sizing organic compounds from inorganic substances and containing chlorophyll like the green plants) dinoflagellates are regarded by botanists as plants, constituting the Class Dinophyceae within the Division Pyrrhophyta of the Algae. Throughout this Index, as in previous editions, they are regarded as plants and therefore the articles and recommendations of the I.C.B.N. have been applied to their nomenclature. The format for this Index follows that used by Lentin and Williams, 1973. The genera are arranged in alphabetical order and the species and subspecies are presented in similar fashion within the genera and the species respectively. Taxa considered invalid, illegitimate or junior synonyms are denoted by quota- tion marks. For clarity and simplicity the abbreviated generic name is not repeated before each species, but the tabulated species names are indented so that no confusion will result from this omission. This practice is acceptable under Article 33, paragraphs 1-2 of the I.C.B.N. which allows, "...any topo- graphical device which indicates that an epithet is associated with a particu- lar generic or other name." The species list includes the author, date, page number, plate and figure numbers for each species which remains within the original generic assignment. For species which have been assigned to a genus by later transfer the author, date and page number of the first valid transfer are listed, and citation of the original description is included in parentheses if the species is now currently assigned to that genus. When further transfer has been affected the complete citation of the original description is included in parentheses only for that genus to which the species is now validly assigned. One exception to the author citation is Jiabo, 1978. This reference is a joint publication by several authors, including Sung Zhi-chen, He Cheng-quan, Qian Ze-shu, Pan Zhao-rin, Zheng Guo-guang and Zheng tue-fang. The word Jiabo represents a collective name for the authors. We have recently been informed by He Cheng-quan that the individual contributions should be recognized. Thus Bohaidina Jiabo should preferably be cited as Bohaidina Sung, He, Qian, Pan, it) G.G. Zheng and Y.F. Zheng, in Jiabo, 1978. Unfortunately, we received this information at too late a date to change the present index. It will, however, be borne in mind when compiling future issues. In cases where a species has been assigned to more than two genera, the first generic name given is that of the original combination. If a species has been transferred out of the genus under which it is listed, the specific name is given in quotation marks and its current generic assignment is listed. The age appearing with each specific name is that of the type material. Every attempt has been made to cross reference all names for species and taxa of lower rank which have been included within two or more genera. Although the present authors try to avoid detailed discussion of taxonomic papers, the magnitude of Stover and Evitt, 1978 and their adopted format demand some comment. For individual genera, these authors recognized: "type species"; "other accepted species"; "provisionally accepted species"; and "problematical species". These groupings, which are concisely defined by Stover and Evitt, op.cit., are treated as follows in the Index. All "accepted species" are listed without reference to Stover and Evitt, op.cit. "Provisionally accepted species" are preceded by a question mark (?) with a note that Stover and Evitt, op.cit. considered each to be a "provisionally accepted species". The "pro- blematical species" are listed without preface but are followed by the note that Stover and Evitt considered each to be a "problematical species". In addition to describing several new genera, Stover and Evitt, 1978 emended several, and also provided "synopses" or "modified descriptions" for most. The latter two headings are not mentioned in the Index. It is our recommendation that the opinion of Stover and Evitt be closely adhered to in the determination ,of whether a generic diagnosis has been changed sufficiently to warrant the notation emend. in accordance with the I.C.B.N. Art. 47. By not following this course of action, considerable confusion my result in the deter- mination of the correct circumscription for many genera. Occasional comments on taxonomic problems are included immediately after the generic or specific entry. One such example is the status of Meiourogony- aulax Sarjeant, 1966b, and its contained species. Gocht, 1975, p.353 consid- ered this genus to be a junior synonym of Lithodinia Eisenack emend. Gocht. He did not, however, effect any formal transfer of species. Subsequently Gocht, 1976, p.334 invalidly (Stafleu, personal communication) transferred several species of Meiourogonyaulax to Lithodinia. Lentin and Williams, 1977b, at the request of Hans Gocht, validly transferred the species of Meiourogonyaulax to Lithodinia. Stover and Evitt, 1978, p.62-63, however, retained the genus Meiourogonyaulax, differentiating it from Lithodinia on the nature of the archeopyle: in the latter genus, the individual paraplates of the operculum are free. In this issue of the Index we have accepted the opinion of Stover and Evitt and retained both Lithodinia and Meiourogonyaulax. Lentin and Williams, 1973 (p.3-5) discussed the infraspecific classifica- tion currently used for fossil dinoflagellates, and recommended that the terms subspecies, variety and forma not be used indiscriminately. Their definitions for these infraspecific categories have been maintained in the present Index. This has necessitated the raising of infraspecific taxa previously described as varietates to the subspecies level, thus creating a "stat.' nov." or status novus. Sarjeant, 1976c (p.10) stated: "In my opinion, the name 'subspecies' carries evolutionary overtones that make its application inappropriate to the forms here treated with. I recognise that the definition of subspecies in the International Code of Botanical Nomenclature carries no such implications; but I prefer to apply the term 'subspecies' either to members of a population exhibiting a morphological feature whose development appears likely to link that species with another, or to geographically or stratigraphically isolated populations, all of whose members show a slight, but consistent, difference from typical forms." Lentin and Williams, 1977b did not concur with Sarjeant's reasoning which was based upon the recognition of evolutionary overtones. Bestowing such a connotation upon the subspecies, they reasoned, would lead to several erroneous conclusions. These authors therefore retained the variety only in the sense of Lentin and Williams, 1973, a course of action which is pursued in this present version of the Index. It has always been the policy of the present authors to adhere to the International Code of Botanical Nomenclature. There is, however, one notable exception. Article 26 states that the author's name does not follow the cita- tion of a subspecies name. Thus Defiandrea phosphoritiea Eisenack subsp. australis Cookson and Eisenack var. Zata Vozzhennikova is correctly written as DefZandrea phosphoritiea Eisenack australis Zata.

  • Evolutionary Trends in the Epithecate Scleractinian Corals
    Evolutionary trends in the epithecate scleractinian corals EWA RONIEWICZ and JAROSEAW STOLARSKI Roniewicz, E. & Stolarski, J. 1999. Evolutionary trends in the epithecate scleractinian corals. -Acta Palaeontologica Polonica 44,2, 131-166. Adult stages of wall ontogeny of fossil and Recent scleractinians show that epitheca was the prevailing type of wall in Triassic and Jurassic corals. Since the Late Cretaceous the fre- quency of epithecal walls during adult stages has decreased. In the ontogeny of Recent epithecate corals, epitheca either persists from the protocorallite to the adult stage, or is re- placed in post-initial stages by trabecular walls that are often accompanied by extra- -calicular skeletal elements. The former condition means that the polyp initially lacks the edge zone, the latter condition means that the edge zone develops later in coral ontogeny. Five principal patterns in wall ontogeny of fossil and Recent Scleractinia are distinguished and provide the framework for discrimination of the four main stages (grades) of evolu- tionary development of the edge-zone. The trend of increasing the edge-zone and reduction of the epitheca is particularly well represented in the history of caryophylliine corals. We suggest that development of the edge-zone is an evolutionary response to changing envi- ronment, mainly to increasing bioerosion in the Mesozoic shallow-water environments. A glossary is given of microstructural and skeletal terms used in this paper. Key words : Scleractinia, microstructure, thecal structures, epitheca, phylogeny.

Ryazanian black shales in a core dose to the eastern margin of the Trøndelag Platform offshore Hel­ geland, northern Norway are overlain by a condensed latest Ryazanian-Barremian sequence of grey and red Utvik Formation equivalent marls and mudstones. Palaeontological studies show that the 'Late Cimmerian Unconformity' represents only a minor hiatus in the Upper Ryazanian. Upper Val­ anginian-Lower Hauterivian beds seem to be absent. The generalized model for the North Sea and adjacent areas (Rawson & Riley 1982) thus seems applicable to more northern areas, as would be ex­ pected if sedimentation was mainly controlled by eustatic sea level changes.

V1cT., 16, 1949 https://doi.org/10.24199/j.mmv.1949.16.07 YERINGIAN (LOvVER DEVONIAN) PLANT REMAINS FROM: LILYDALE, VICTORIA, WITH NOTES ON A COLLECTION FROl\f A NE\V LOCALITY IN THE SILURO-DEVONIAN SEQUENCE By Isabel Cookson, D.Sc., Botany Department, University of ]lelbourne Plates IV-VI, Fig. 1. (Receiwd for publication June 21, 1949.) The main object of the present paper is to give a description of plant remains from type localities in Yeringian beds at Lily­ dale, Victoria. The principal locality (Hull Road, Lilyclalc) was referred to in a prnvious paper (Cookson 1935, p. 146) and subsequently a list of the main types collected there was recorded ( Cookson 1945). This collection now includes remains referable to or at least comparable ·with Sporngonites, Zostaophyllmn, )�aJTltL"ia a11d Iledeia. It will be supplemented by rnference to speeimens from two additional outcrops, one neaT Lilydale and the other at Killara, about 7l miles further east. The occurrence of plants iu this area is of special shatigraphical interest. For many years, the Y eringian series was believed to belong to the Silurian period, but the position assigned to it within that range of time varied according to the author (see Gill 1942, Table I). Chapman and Thomas (1935), when defining the Victorian Silurian succession, correlated the YeTingian with the Upper Ludlow of Britain. Beneath it they placed the Melbournian division (Lower Ludlow), whilst the basal series, the Keilorian or Lower Silurian, was correlated with the Llandoverian of the British succession. Later Thomas (1937), in dealing with Silurian 1·ocks of the Heathcote area, pointed out that detailed work was necessary to determine "how much of the Devonian is included in the Yeringian.'' In 1938 Shirley noted that "the Yeringian contains at least one fauna similar to that of the Baton River series" (Lower Devonian of New Zealand).

Rothwell Distinguished Professor of Environmental and Plant Biology Leslie A. Flemming Dean, College of Arts and Sciences TOMESCU, ALEXANDRU MIHAIL FLORIAN. Ph.D. November 2004. Biological Sciences Late Ordovician – Early Silurian terrestrial biotas of Virginia, Ohio, and Pennsylvania: an investigation into the early colonization of land (284 pp.) Director of Dissertation: Gar W. Rothwell An early phase in the colonization of land is documented by investigation of three fossil compression biotas from Passage Creek (Silurian, Llandoverian, Virginia), Kiser Lake (Silurian, Llandoverian, Ohio), and Conococheague Mountain (Ordovician, Ashgillian, Pennsylvania). A framework for investigation of the colonization of land is constructed by (1) a review of hypotheses on the origin of land plants; (2) a summary of the fossil record of terrestrial biotas; (3) an assessment of the potential of different continental depositional environments to preserve plant remains; (4) a reevaluation of Ordovician-Silurian fluvial styles based on published data; and (5) a review of pertinent data on biological soil crusts, which are considered the closest modern analogues of early terrestrial communities.
